A natural anti-seepage material for artificial lake anti-seepage - sodium bentonite waterproof blanket, this bentonite waterproof blanket made of sodium bentonite particles, sodium bentonite particles have good anti-seepage performance and high expansion coefficient. The high standard and environmentally friendly anti-seepage material is a natural environmental protection waterproof layer.
Natural sodium-based swelling waterproof blanket layer, it should be remembered that sodium bentonite has the characteristics of water swelling, bentonite can expand more than 24 times when it meets water, so that it forms a uniform colloidal system with high viscosity and low fluid loss. Under the restriction of two layers of geotextiles, the bentonite is changed from disorder to ordered expansion. The result of continuous water absorption expansion is to make the bentonite layer itself dense, thus having waterproof effect, so that the sodium-based bentonite waterproof blanket http:// has A certain overall shear strength is a true natural waterproof layer.
The sodium-based bentonite waterproof blanket has excellent environmental protection waterproof layer, excellent tensile and anti-lining effects. Therefore, the sodium-based bentonite waterproof blanket should be applied to waste landfill, underground reservoir and underground infrastructure construction in environmental engineering. In the project, the sealing, isolation and leakage prevention problems are solved, the effect is good, and the damage resistance is strong.
The quality of the sodium bentonite waterproof blanket is directly related to the bentonite particles in the middle. Some bentonite has a high expansion coefficient and can be more than 24 times without the sodium anti-seepage coefficient. Some bentonite particles have a low expansion coefficient and are not suitable for doing. Anti-seepage blanket, and our company's sodium-based bentonite particles are all made of bentonite particles from Jianping County, Liaoning Province. The bentonite particles are uniform, have good texture and high expansion coefficient, and are suitable for raw materials of sodium-based bentonite waterproof blanket.
