High-Performance Sodium Bentonite Geosynthetic Clay Liner For Impermeable Properties
Product Introduction
Sodium bentonite waterproof blanket is made of sodium bentonite as the main raw material by needling, needling coating or adhesive processing. Sodium bentonite can expand more than 24 times when exposed to water, forming a uniform colloidal system with high viscosity and low filtration.
Product Properties
Excellent waterproof and impermeable properties. In addition, sodium bentonite is an inorganic material, does not occur aging reaction, good durability, and environmental protection.
Product Application
Sodium bentonite waterproof blanket is extensively utilized in municipal engineering, subway, underground engineering of buildings and roof reservoir seepage prevention, as well as domestic waste landfill, sewage treatment site, seepage prevention and reinforcement for dams of rivers, lakes and reservoirs and other domains.
