Jilin Siping bentonite composite waterproof blanket special supply

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 thermal 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 swells 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 Punching
Pinhole punching is used to allow the fabric to penetrate the bentonite layer to form a fully integrated, re-reinforced composite bentonite waterproof blanket that is resistant to shear, creep resistance and stability Advantages such as sex are of great significance in any application conditions.
Composite geomembrane, bentonite waterproof blanket, geomembrane, geomembrane and other waterproof and anti-seepage geotechnical materials. Composite geomembrane is a polyethylene geomembrane as the anti-seepage body, and short fiber needle punching with excellent isolation drainage and waterproof properties Geotextiles are composited by hot pressing, usually with one cloth and one film, two cloths and one film, or multiple cloths and multiple films. Composite geomembrane has complete width and thickness 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 is also called bentonite waterproof mat. Bentonite waterproof blanket is filled with sodium bentonite particles between woven geotextile and non-woven geotextile. The upper non-woven fiber is passed through the bentonite particles through special processes and equipment. It is made by attaching it to the underlying fabric using a special method. 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 waterproofing and anti-seepage under various construction conditions. project. Bentonite waterproof blankets are mainly used for anti-seepage or sealing in civil engineering, water conservancy projects, and environmental protection projects, such as anti-seepage design of channels, reservoirs, and water dams, foundation, perimeter, and roof sealing design of garbage dumps, artificial lakes, and landscape lakes. Leak-proof design of artificial rivers and lakes, etc.
