What are the functions and uses of bentonite waterproof blanket?
Because sodium bentonite is a natural inorganic mineral particle size less than 2 m, the main component is montmorillonite crystallite formed by volcano glass thixotropic, service life can reach 200-700 million years, it will not be because of long time frequent aging or corrosion, but not change the chemical properties, so waterproof the performance of permanent.
Sodium bentonite can absorb 5 times its weight in water, can be expanded to about its volume of about 13-16 times, but also has high water density and self repair, recovery function, expansion after packing to 2 mm -5 mm wide cracks. In theory is the most close to the perfect waterproof material.
