High-alumina refractory bricks are made from bauxite or kaolinitic clays. The definition of high-alumina refractory bricks contains between 50 and 87.5 percent alumina. They are much harder and tougher than fireclay refractories at high temperatures and in basic environments. In addition, high-alumina refractory bricks exhibit better volume stability and abrasion resistance. High-alumina bricks are used in blast furnaces, blast-furnace stoves, liquid-steel ladles, etc.
Application of High Alumina Bricks
The high alumina bricks are mainly used in masonry in blast furnaces, hot blast furnaces, electric furnace roofs, blast furnaces, reflecting furnaces, and lining of rotary kilns. In addition, high alumina brick is widely used in open hearth furnace lattice brick, plugs used in casting systems, nozzle brick, etc. But the price of high alumina brick is higher than the clay brick, so we do not need high alumina brick when the clay brick can satisfy the demand.

The rough surface HDPE geomembrane is based on the traditional production process of polyethylene 3D geonet factory price, and the technical innovation of the production equipment is transformed, so that the surface of the produced polyethylene geomembrane forms a granular rough surface, which improves the geomembrane surface. At the same time, compared with the smooth mask of the same specification, the tensile strength is stronger, the rough grain of the rough mask surface, when laying the film, it will form a small gap between the film and the base surface, which can enhance the HDPE geonet manufacturers Anti-bearing deformation is generally used in projects where the surface of the slope membrane needs to be covered with soil and requires a large friction coefficient.
When it comes to geotextiles, everyone is not unfamiliar. Of course, wholesale filament nonwoven geotextile are very widely used. When they are commonly used for greening, they will be covered with a layer of geotextile before covering the soil. , So many landscape projects will use geotextile, which is a typical application.
Of course, geotextile can also be used for road construction, laying on the road to protect the roadbed, and can be recycled after use. Geotextile has a simple structure, and compared with other engineering materials, the price of geotextile is also very economical. Geotextile can be customized according to different specifications to meet different engineering requirements and is very flexible.
In landscaping, geotextiles are also used to protect large trees, especially when the weather is very cold in winter. wholesale polyester nonwoven geotextile are wrapped around the roots to protect the trees and make garden maintenance easier.
The three colors commonly used for geotextile, white, black, geotextile, design and color, are indistinguishable from function, only the quality of raw materials and the length of service life. Generally speaking, white wholesale polypropylene nonwoven geotextile is widely used, whether it is a real estate project The Botanical Garden Project, the recent environmental audits, and the environmental requirements of raw materials are also getting higher and higher, so a good raw material brings good products. We always insist on serving customers with good materials, good products, and good services.
To be precise, the plastic film is a kind of plastic film. Geotextile is a synthetic material, it has woven geotextile, needle-punched geotextile, impervious geotextile and so on. Geomembrane is a commonly used anti-seepage polypropylene nonwoven geotextile for sale. Geomembrane is a geomembrane material composed of plastic film and non-woven fabric.
Geomembrane has better water barrier and impermeability than ordinary geomembrane. It can also be distinguished literally. One is the film, and the other is the cloth. Of course, the roughness of the cloth and the micro gaps in the weave are not low in water permeability. Of course, this has not been fully understood. Geomembrane consists of plastic film and non-woven fabric. It not only contains the excellent characteristics of the two materials, but also forms new advantages due to the complementarity of the two materials.
Geomembrane is widely used in water conservancy projects and other projects. Geomembrane is a geosynthetic material with very low water permeability, which can ensure good anti-seepage effect, play a good anti-seepage protection in engineering projects, and promote the smooth progress of the project.
Where is the anti-seepage function of geomembrane? For example, the main mechanism of aquaculture geomembrane manufacturers is the impermeability of plastic film to block the leakage path of the earth dam, with its greater tensile strength and elongation to withstand the water pressure and adapt to the deformation of the dam body. Or, in the traditional flood control and emergency rescue, two measures are taken for the safety of various buildings: the first is protection, which is to prevent the emergence of the danger; the second is emergency rescue, that is, once the danger occurs, effective measures must be taken to eliminate it quickly Danger. The most commonly used traditional talents for flood control and emergency rescue are soil, sand, stone, straw bags, and hemp bags. They have been used for flood control for a long time, and the geomembrane has a good effect. It is still the main material for flood control and emergency rescue. It can be seen that the high quality environmental geomembrane has a significant anti-seepage effect.
Polyethylene membrane series products: HDPE impermeable membrane, LDPE flexible waterproof membrane, high-density polyethylene environmental geomembrane for sale used in industrial and mining enterprises sewage tank anti-seepage, waste water tank anti-seepage, chemical reaction tank anti-seepage, acid-base pool anti-seepage, sludge tank Environmental protection projects such as anti-seepage, anti-seepage for sedimentation tanks, anti-seepage for toxic liquid collection tanks, waterproofing, anti-seepage and anti-corrosion for power plant adjustment pools.
There are more and more different types of towels on the market, and our hotel towels are only in these categories
1. Jacquard towel You can find some terry on the wholesale custom promotional velour beach towel, and some are cloth files, which are lower than the terry. After the craftsmanship, these irregularities can show various patterns and patterns. The process of this towel is relatively more complicated, and the price is slightly higher than ordinary towels.
Second, broken towel In addition to the terry, there will be a large or small cloth stall in the middle of the towel. These towels are broken towels; its process can be varied; it can weave various patterns and patterns to meet the hotel's personalized customization.
3. Embroidered towel Various patterns can be embroidered on the produced finished new designs 70x140cm towel set cotton beach towel to improve the ornamental value of the towels and have a certain added value. For example, embroidering a certain hotel indicates that this towel was customized by a certain hotel. You can know which towel is at a glance, and it also plays a certain role in publicity.
4. Active printing towels A printing dye directly printed on velour reactive full-color printing beach towels. Most of the currently used is a new type of environmentally friendly dyes, non-toxic dyes, has gradually replaced ordinary paint printing. Paint printing is easy to distinguish. The pattern color of the active printing is shiny, and the paint printing is not shiny, and the terry or suede of the paint printing will be stained together, and there is no fluffy feeling. Paints are mostly used to print fonts, lines and reduce printing costs. The hotel generally does not use reactive printed towels, but usually in sports towels, gift towels and other places.
Waterproof geotextile is a water-permeable geosynthetic material made of synthetic fibers by needle punching or weaving, also known as high quality filament nonwoven geotextile. It is one of the new materials geosynthetic materials. What is the application of non-woven geotextile?
It is understood that the use of polyester staple fiber filament nonwoven geotextile manufacturers can isolate building materials with different physical properties, so that two or more materials will not be lost or mixed, and the overall structure and function of the material will be maintained, so that the structure can bear the capacity Strengthen, this product also has good water conductivity, can form a drainage channel inside the soil body, and discharge the excess liquid and gas in the soil structure; Good air permeability and water permeability, allowing water flow through, effectively intercepting soil particles, fine sand, small stones, etc., to maintain the stability of water and soil engineering.
The use of waterproof filament nonwoven geotextile factory price can also enhance the tensile strength and deformation resistance of the soil body, enhance the stability of the building structure to improve the quality of the soil body; when the water flow scours the soil body, it can effectively diffuse, transfer or decompose the concentrated stress To prevent the soil from being destroyed by external force and better protect the soil.
For hotel towel suppliers, they are familiar with the characteristics of hotel supplies. The following is a correct understanding of the characteristics of hotel towels with the editor, which can more accurately identify the quality of the China 100% cotton round beach digital printing towel and correctly master the washing skills.
1. It is highly absorbent: The water absorption of hotel towels has a great relationship with our use of pure cotton materials. The orange petal technology divides the filament into eight petals, which increases the surface area of the fiber and increases the pores in the fabric. The capillary wicking effect is used to enhance the water absorption effect. It absorbs water quickly and dries quickly as its distinguishing characteristics.
2. Strong detergency: Hotel wholesale velour reactive digital printing beach towel have strong detergency, because the fineness of the fiber is 1/10 of silk and 1/200 of hair. Its special cross-section can more effectively capture dust particles as small as a few microns. obvious.
3. Hair removal is not easy: The hotel bath towels are not easy to depilate. This feature has a lot to do with the raw materials used. We use imported cotton yarn for weaving. High-strength synthetic filaments are not easy to break. At the same time, the fine weaving method is adopted. Shedding off the surface of the towel.
4. Long life: The long lifespan of hotel custom comfortable digital printing microfiber beach towel free sample is due to the high strength and toughness of the cotton fiber used in the raw materials, so its service life is more than four times that of ordinary towels, and it will not deform after repeated washing.
5. Not easy to fade: The characteristics of hotel bath towels that are not easy to fade have an inseparable relationship with the weaving and bleaching and dyeing of our towel manufacturers. The dyeing process uses dyes for pure cotton fiber materials. Its retardation, migration, high temperature dispersion, and decolorization indicators have all reached Strict standards for export to international markets.
There are several reasons why the hotel towels are damaged: 1. There are burrs on the drum of the washing machine or some parts are not smooth. It is very likely that the wholesale super water-absorbent microfiber bath towel will be scratched or worn during the washing process, which is manifested as yarn drawing and yarn following, and then small holes appear and gradually expand.
2. The sorting work before washing is not serious, and some sharp or hard debris is mixed in it, causing damage during washing.
4. Distribute poorly during washing and dehydration or take too long time for high dewatering, mechanical force leads to breakage, or the washing time is too short, the number of times is low, the washing residue or the washing procedure is defective, the residual alkali and residual chlorine are not neutralized .
5. The quality and storage environment of hotel wholesale microfiber gym bath towel. The cotton fabric must be stored away from moisture, the warehouse should be well ventilated, and the edges of the shelf should be smooth, etc. At the same time, the towel warehouse should be protected from insects and rats.
There are several reasons why the hotel towels are damaged: 1. The feeding time is not correct during washing. Do not feed when the amount of water in the machine is insufficient. Pay particular attention to bleaching chemicals. This will easily concentrate the detergent on the wholesale embroidery microfiber sport towel and damage the towel.
2. Improper use of bleach. Laundry should be used with caution in bleaching detergents, especially bleaching powder (chlorine bleaching agent). If the temperature is not appropriate, the concentration is too high, too much residue after washing, etc. will cause the microfiber sublimation printed sports towel to change color or even appear small holes.
3. The towel is stained with corrosive chemicals. Some of the various cleaning products used in the hotel are corrosive, especially some strong acid detergents have a great impact on cotton fabrics. If the waiter collects or cleans the room, the cotton fabrics will be accidentally stained with these detergents If it is not cleaned immediately, the wholesale microfiber custom printed towel will be partially damaged and the fastness will be poor.
4. Misuse of detergent. The cleaning agents in the laundry room are all chemical products, which require certain knowledge and responsibility and correct use. Otherwise, there may be mistakes in the mixing of the washing products, or even the wrong feeding, which will also lead to this result.
The waterproof geotextile reduces the binding force between the surface layer and the lower layer. After calculation, after adding the polyester nonwoven geotextile manufacturers, the binding force at the interface between the two layers is obviously reduced, thereby reducing the maximum tensile strain of the cover layer. Now let's take a closer look at this knowledge introduction?
As permeated asphalt can effectively prevent surface water from infiltrating into the lower layer of the road and prevent the lower layer from further deterioration. As polyester nonwoven geotextile factory price penetration of asphalt can effectively prevent groundwater from infiltrating the human interface, reducing the peeling damage of asphalt cover layer at the reflective cracking. The sandwich material can slowly release the temperature drop of the cement concrete slab and reduce the displacement of the cement concrete slab. When the tensile stress of the asphalt cover layer due to the displacement of the old cement concrete slab exceeds the tensile strength of the asphalt cover layer, a cracking situation will occur, so we have to deal with the problem at the root of the flow to adjust for a better cure That is a good raw material.
In fact, when we use waterproof geotextile, in order to ensure the quality of the product, we need to buy it from a more formal manufacturer, because such a manufacturer has more advanced equipment and technology to maintain the performance of the product.
The production of geotextiles must follow strict production standards, and the use of geotextiles also needs to be used correctly to exert their effects. The following editors will briefly introduce the role of geotextiles in isolation.
Geotextile isolation can use polyester staple fiber needled wholesale polypropylene nonwoven geotextile to isolate construction materials with different physical properties. The two or more materials are not lost or mixed, the overall structure and function of the materials are maintained, and the bearing capacity of the structure is strengthened. When the water flows from the fine soil layer into the coarse soil layer, the geotextile can be filtered by using polyester staple fiber needled geotextile with good air permeability and water permeability, allowing the water to pass through, and effectively carrying the fluid soil particles, fine sand, Small stones, etc., to maintain the stability of water and soil engineering.
Regarding the application technology of wholesale filament nonwoven geotextile synthetic materials, the state has proposed standard technical requirements in terms of anti-seepage, filtration, drainage, reinforcement, protection, etc., which has greatly accelerated the pace of promotion and application of new materials. This material has been widely used in the anti-seepage project of irrigation channel, combined with construction practice, the application technology of geotextile.
1. Since the synthetic fibers used for geotextile production are mainly nylon, polyester, polypropylene, and ethylene, they all have strong resistance to burial and corrosion; 2. The geotextile is a permeable material, so it has a good filter isolation function; 3. Non-woven wholesale polyester nonwoven geotextile has good drainage performance due to its fluffy structure; 4. Geotextile has good anti-puncture ability, so it has good protection performance; 5. Geotextile has a good friction coefficient and tensile strength, and has geotextile reinforcement properties.
Geotextile believes that many people know that in the process of use, if it appears damaged, how should it be repaired? Today, I will briefly introduce it to everyone!
In fact, it will show this kind of damage. We can still repair it. During the repair process, we need to mark the damaged parts in time, and then arrange it. Be sure to go through the laying and thermal connection of the high quality filament nonwoven geotextile. Small pieces are used to repair worn geotextiles. The small pieces of filament nonwoven geotextile for sale are at least 200mm longer than the missing edges in all directions, and the operation needs to be stricter, so as to better ensure the quality of the product in the future use process To reduce the occurrence of damage.
Through the above introduction, I believe that you have a new understanding of this knowledge. If you have any better methods, please share with us in time. I believe that in this process, you can learn a lot knowledge.
There are many types of geotextiles, permeable geotextiles are one of them. For permeable geotextiles, it is a high tensile strength material, and soil is a low tensile strength material. However, when the permeable wholesale polypropylene nonwoven geotextile is reasonably added to the soil, the stress distribution in the soil can be changed, and the lateral deformation of the soil can be restrained, thereby improving the stability of the structure. The following editors will briefly introduce the following three forms of enhancement of permeable geotextiles:
I. Diaphragm type: when laying permeable geotextile on soil surface for temporary road;
2. Anchor type: When the permeable geotextile covers the soil body, it will pull it out after being stressed. The key lies in the frictional resistance at the contact surface between the permeable polypropylene nonwoven geotextile for sale and the soil and the situation of mutual engagement.
3. Shear type: It is applied when the soil is under stress and a direct shear action occurs between the permeable geotextile and the soil interface.
The composite geomembrane is employed for day and night traffic of high-grade highway pavement and bridge pavement. Addition amount: kg / m3, abrasion layer: 3.5kg / m3.
When 2.5 kilograms of asphalt pavement 5000 1.5 special reinforcing fibers are added per kiloliter of asphalt concrete, the composite wholesale HDPE geomembrane has approximately 5000-6000 2.5 per kiloliter of asphalt concrete. There are quite 850 million separated fibers during a three-dimensional structure. it's evenly distributed in> 6000 3.5 asphalt concrete, which provides an honest reinforcement effect for asphalt concrete, thereby ensuring that asphalt concrete has excellent strength, stability, durability and crack resistance.
Benefit analysis: The lastingness of the composite geomembrane is greatly improved. a rise of about 15% can improve the oil permeability. If the quantity of asphalt is that the same, the void ratio will increase, which can help improve the steadiness of the asphalt concrete. It can increase by 0.3%. When laying the film, it must be laid from top to bottom.
The film should be pressed tightly between the film and therefore the base surface, but it shouldn't be pulled too tight. Generally, it should be slightly loose, but there should be no air bubbles at the rock bottom of the film. Because the geomembrane is comparatively thin and lightweight, it's easy to be blown by the wind before the protective layer is laid, therefore the area of one film shouldn't be large, and it's best to hide the protective earth with the film.
According to the knowledge provided by the manufacturer, the width of the composite geomembrane is 1.0 ~ 1.9m. This project uses a width of 1.9m to scale back the joint material. The joints have methods like hot sticking, gluing, lap jointing, etc. This project is meant with gluing, and therefore the joint width is 50mm. Now there's a replacement sort of composite geomembrane-warp knitted composite textured geomembrane factory price.
The warp-knitted composite geomembrane may be a new sort of geotechnical material made from man-made fiber (or glass fiber) as a reinforcing material and compounded with a composite geomembrane.
Warp-knitted composite geomembrane is different from the general composite geomembrane. the most important feature is that the intersections of the warp and weft aren't curved and that they are during a flat state.
Tie the 2 together firmly with a binding line, which may be synchronized more comprehensively and uniformly, withstand external forces and distribute stress, and when the external force is applied to tear the fabric, the yarn will gather along the initial crack, increasing the tear resistance.
When the warp knitting is combined, the warp knitting yarn is employed to repeatedly pass between the warp, weft yarn and therefore the fiber layer of the needle-punched non-woven waterproof geotextile, in order that the three are knitted into one. Therefore, the warp-knitted composite geomembrane not only has the characteristics of high lastingness and low elongation but also has the waterproof performance of the composite geomembrane.
PET Geogrid is often used for highway, railway, embankment, bridge abutment, construction road, wharf, revetment, flood dike, dam, beach control, freight yard, slag field, airport, sports field, environmental protection construction, soft soil foundation reinforcement, wall reinforcement, high slope treatment and another engineering, and exposed to the surface water conservancy projects.
Features Of PET Geogrid 1. Strong, creep small, adapt to all or any sorts of environmental soil high quality biaxial geogrid, can fully meet the utilization of the high wall within the high-grade highway. 2. It can effectively improve the locking and occluding action of the reinforced bearing surface, greatly enhance the bearing capacity of the inspiration, effectively restrain the lateral displacement of the soil, and enhance the steadiness of the inspiration. 3. compared with the normal grid has more strength, bearing capacity, corrosion resistance, aging resistance, friction coefficient, uniform holes, convenient construction, long service life, and other characteristics. 4. more suitable for deep-sea operations, embankment reinforcement, fundamentally solve other materials do stone cage thanks to long-term erosion by seawater caused by low strength, corrosion resistance, short service life, and other technical problems. 5. It can effectively avoid the development damage caused by the crushing and destruction of machinery and tools within the construction process.
Landfill leakage can cause serious environmental pollution. Soil contamination, salinization, are going to be poison, parasites, pathogenic bacteria and other pathogens within the soil that can make people sick. Penetration will pollution of groundwater, and eventually entered the human organic phenomenon, causing serious harm to the physical body. Starting within the 80s within the landfill anti-seepage treatment abroad utilized in 1-2 mm thick of HDPE, environmental geomembrane for sale price has become a mature technology and getting more and more applications. China’s environmental protection landfill started late, but in recent years, under the eye of the state environmental protection administration and therefore the improvement of national environmental protection awareness, the environmental protection landfill with HDPE anti-seepage treatment has been widely utilized in the country.
For landfill, wholesale HDPE geomembrane thickness is often 0.75mm, 1.0mm, 1.25mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, and 3.5mm, etc. consistent with the wants of national standard CJ/ t234-2006 and therefore the actual situation, the recommended thickness of HDPE geomembrane should be a minimum of 1.5mm, and therefore the tolerance should be within ±3%. However, 1.5mm and 2.0mm are more commonly used as landfill sites.
Of course, the selection of the thickness of environmental geomembrane manufacturers purchasable utilized in different positions of the landfill site is additionally different, mainly because of the substrate seepage prevention, slope seepage prevention and field sealing cover. differing types of film utilized in a special position, as the substrate with a smooth surface, slope with a rough surface. additionally, there are many other factors affecting the selection of thickness, like landform, soil quality, impermeable materials, impermeable requirements then on.
The points of the HDPE geomembrane are made by the rolling roller of the model, the points are evenly distributed, the surface of the points HDPE geomembrane looks beautiful, the HDPE geomembrane of the stagnation point improves the friction coefficient, and therefore the front & back of the low price aquaculture geomembrane surface are often made from different materials and different colors, which may be integrated into one, within the engineering application, the front and back of the merchandise are often set consistent with the geological conditions and engineering requirements.
Products of the assembly process in retaining the first resin itself have excellent mechanical properties and good elongation and stable chemical performance, on the idea of column point HDPE geomembrane manufacturers by adding a particular proportion of functional additives by melting, extrusion, rolling, drawing, reasonable control of the method is further enhanced products like tensile, abrasion resistance, durability performance, single stationary point textured geomembrane factory price, the ratio of functional additives added fusion, make products to be immune to acid and alkali, microbial and chemical erosion features to further improve the mechanical properties of the merchandise than an equivalent general process of rough antiskid geomembrane nearly 3 times higher.
A composite drainage mat is a new kind of drainage geotechnical material. It is made of high density polyethylene (HDPE) by special extrusion process.
It has a special structure of three layers. The middle ribs are rigid and arranged longitudinally to form drainage channels. The upper and lower ribs form supports to prevent geotextile from embedding into drainage channels, which can maintain high drainage performance even under high loads. Double-sided bonding seepage geotextile composite use, with “anti-filtration – drainage – ventilation – protection” comprehensive performance, is the most ideal drainage material.
It is mainly used in railway, highway, tunnel, municipal engineering, reservoir, slope protection, and other dimple drainage board factory price projects.
1. The composite drainage mat is composed of one or two layers of non-woven geotextile and one layer of the three-dimensional composite geogrid core with different structures, which has the function of drainage isolation. 2. A composite drainage mat is applied to roof planting, roof planting, underground sidewall protection and drainage, bottom drainage, tunnel waterproof and drainage, highway slope protection, saline, and alkaline land, desert planting, artificial lake; 3. The application function of the dimple drainage board factory price can be bent construction, rapid drainage of the waterproof layer of static water, HDPE geomembrane water, timely reduce the load of the main structure, protect the waterproof layer and structure, avoid suffering from soil backfill, plant roots, acid and alkali, underground insects and microorganisms damage to the waterproof layer.
Combined with a waterproof layer, it has a double waterproof and impermeable function, so that waterproof layer can isolate gas and prevent oxidation, and greatly improve the life of a waterproof system. Flexible material, high compressive and tensile strength, to meet the needs of crack elongation and road facilities. Durable material, to meet all kinds of planting roofing use, but also can apply the old building roof planting. Construction is simple but also can be used in the old building roof planting.
