Shaanxi Hanzhong bentonite composite waterproof blanket is professionally produced

Bentonite composite waterproof blanket is a new type of geosynthetic material. It is made of graded natural sodium bentonite particles and the corresponding admixtures evenly mixed. The bentonite particles are fixed between two layers of geotextile through special processes and equipment to make a bentonite waterproof blanket. It has all the characteristics of geotechnical materials and Has excellent waterproof (permeability) performance. The waterproofing mechanism is: bentonite particles expand when exposed to water to form a uniform colloid system. Under the restriction of two layers of geotextile, the bentonite expands from disorder to order. The result of continuous water absorption and expansion is to make the bentonite layer itself dense and waterproof. effect.
Physical characteristics:
It has excellent waterproof and anti-seepage properties and is anti-seepage and hydrostatic pressure can reach the above permeability coefficient. Bentonite is a natural inorganic material that will not undergo aging reaction. It has good durability and will not cause any harm to the environment. It is an environmentally friendly material that has all the characteristics of geotextile materials, such as separation, reinforcement, protection, filtration, etc. It is easy to construct and is not restricted by the construction environment temperature. It can also be constructed below ℃. During construction, you only need to lay the waterproof blanket flat on the ground. During construction on the facade or slope, fix it with nails and washers and overlap it as required.
. Easy to repair. Even after the waterproofing (seepage) construction is completed, if the waterproofing layer is accidentally damaged, you can regain the perfect waterproofing performance by simply repairing the damaged part.
, the performance-price ratio is relatively high and has a wide range of uses.
The product width can reach meters, which matches the international geotextile (membrane) specifications, greatly improving the construction efficiency.
As a new type of environmentally friendly and ecological composite anti-seepage material, sodium bentonite waterproof blanket has been widely used in civil engineering projects such as water conservancy, environmental protection, transportation, railways, and civil aviation due to its unique anti-leakage performance. Basic treatment of landfills and anti-seepage of artificial lakes, reservoirs, channels, rivers, roof gardens, anti-seepage basements, subways, tunnels, underground passages and other underground buildings.
Bentonite waterproof blanket is a composite anti-seepage material made of a layer of clay or other low-permeability mineral materials covered with geotextile or geomembrane through needle punching or suturing. Our company uses sodium bentonite with high expansibility. When exposed to water, it expands to produce water and acts to form an impermeable gel. At the same time, bentonite also has the ability to store water. Its absorption and water content can reach more than three times its own weight. Bentonite waterproof blanket: Bentonite waterproof blanket product specifications: mass per unit area /㎡ Width - Performance characteristics of bentonite waterproof blanket: Compared with compacted clay liner, it has the advantages of small size, light weight, good flexibility, good sealing, good shear strength, high shear strength, simple construction and adaptability to uneven settlement. Bentonite waterproof blanket uses: It is mainly used in waste gas landfills, underground reservoirs, underground infrastructure construction and other projects in environmental engineering to solve the problems of sealing, isolation and anti-leakage. It has good effect and strong resistance to damage
Bentonite composite Waterproof blankets can be widely used in underground waterproofing and anti-seepage construction in municipal administration, highways, railways, water conservancy, environmental protection and industrial and civil buildings. When used in lining systems of landfills or water conservancy projects, compared with compacted clay linings, the hydraulic permeability coefficient equivalent to that of bentonite waterproof blankets is much thicker, so the use can significantly increase the tension strain up to %. Under the same strain, the permeability of bentonite waterproof blankets and geomembranes will increase sharply. In addition, there are many advantages such as bentonite waterproof blanket, which has the characteristics of easy overlapping, simple installation, fast construction speed, short construction period and low cost. The bentonite waterproofing materials produced and sold by our company have passed quality system certification and have been registered for product supply in the Beijing Building Materials Center, and have been used in many key projects. At present, the company has an annual production capacity of 10,000 square meters and can produce bentonite composite waterproof mats of any specification within the width and length according to user requirements.
Composite clay liner (bentonite waterproof blanket)
Bentonite waterproof blanket is composed of two layers of geotextile and a bentonite layer. The upper non-woven geotextile penetrates the bentonite layer by pinhole punching and is integrated with the bottom geotextile (woven or non-woven). This method can form a strong mechanical bond between the two layers of cloth. The fabric is then repaired and permanently reinforced in place using a heat treatment process known as heat bonding. Utilizing the property of sodium bentonite to swell when exposed to water, people naturally apply it in geocomposite clay liner products. When exposed to water in a closed condition, bentonite expands to form a low-permeability clay layer that is as water-resistant as several feet of compressed clay. Its unique properties including increased internal shear resistance and long-term creep resistance make composite bentonite waterproof blankets suitable for use in a variety of waterproof lining systems.
Unique pinhole stamping
The use of pinhole stamping allows the fabric to penetrate the bentonite layer to form a fully integrated and reinforced composite bentonite waterproof blanket, which has excellent shear resistance, creep resistance and stability. Advantages are important in any application condition.
Composite geomembrane, bentonite waterproof blanket geomembrane, D geomembrane and other waterproof and anti-seepage geotechnical materials. Composite geomembrane is a polyethylene geomembrane as an anti-seepage body and a short fiber needle-punched geotextile with excellent isolation drainage and waterproof properties. It is generally made of one cloth and one film, two cloths and one film, or multiple cloths and multiple films. Composite geomembrane width-thickness-complete specifications. Composite geomembrane has the characteristics of high strength, good elongation performance, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, good anti-seepage performance, and is not affected by climate. Composite geomembranes are mainly used in water conservancy dams, road construction, airports, drainage, construction, environmental protection, water supply and other projects. It plays the role of anti-seepage, protection and reinforcement in the project. Bentonite waterproof blanket, also called bentonite waterproof pad, bentonite waterproof blanket is filled with sodium bentonite particles between woven geotextile and non-woven geotextile. The method is connected to the lower fabric. The bentonite particles in the waterproof blanket made by this method do not flow in one direction, so it can form a uniform waterproof layer in the entire range. It has excellent waterproof and anti-seepage materials and can be widely used in waterproof and anti-seepage projects under various construction conditions. Bentonite waterproof blankets are mainly used for anti-seepage or sealing in civil engineering, water conservancy projects, and environmental protection projects, such as the anti-seepage design of channels, reservoirs, water tyrants, the foundation, periphery, and cap sealing design of garbage dumps, artificial lakes, landscape lakes, artificial rivers, and lakes. Leak-proof design and so on.
