The company adheres to the principle of honesty, trustworthiness, mutual benefit and win-win to provide users with products and after-sales services, so that you can buy safely and use sparingly. Over the years, our factory has accumulated rich production experience, constantly improved the production process, and strived to make * * * good products to give back to new and old customers. We have always been with you on the road of geotechnical materials!
Bentonite The waterproof blanket is made of expansive Sodium bentonite Filled in reunite with Geotextile Between and non-woven fabric, the bentonite anti-seepage pad made by needle punching method can form many small fiber spaces, so that the bentonite particles can not flow in one direction, and will form a gel with uniform density in the pad when encountering water Waterproof layer To prevent water leakage. Mainly used for artificial lake waterscape Landfill , underground garage.
1、 Bentonite waterproof blanket is not. The main waterproof component of the bentonite waterproof blanket is sodium bentonite, which is an inorganic mineral of this kind. There is no problem, so the service life of the bentonite waterproof blanket is as long as its structure.
2、 Bentonite waterproof carpet fruit is harmful to biology. When sodium bentonite encounters water and expands, negative pressure will be formed inside the blanket. When rats, lobsters, tree roots and other organisms destroy the blanket, the surrounding bentonite particles or cementitious materials can quickly migrate to repair the cavity, which is what we call the self-healing function of the bentonite waterproof blanket.
3、 Bentonite waterproof blanket * * * adapts to uneven settlement. First of all, the bentonite waterproof blanket is flexible and light, which can better adapt to uneven settlement. Moreover, the bentonite waterproof blanket is lapped, unlike Geomembrane It is welding, and the overlapping parts can have proper dislocation during settlement without affecting the seepage control effect, and the materials will not be damaged as a whole.
4、 Bentonite waterproof blanket is not easy to be broken or punctured. Therefore, the requirements for laying site conditions are lower than that of geomembrane, and even if punctured, the possible leakage points will also be self generated due to the migration of bentonite.
5、 Bentonite waterproof blanket has simple and reliable connection and construction efficiency. In particular, and The Conduit Or when the building is connected around, it is simpler than the geomembrane, and the sealing performance of the joints is also easy * * *, and the product range can reach 6 meters, greatly improving the construction efficiency.
6、 Bentonite waterproof blanket can overcome freeze-thaw and dry cycle. Bentonite waterproof blanket is easy to transport and install, and because bentonite is an inorganic mineral, its anti-seepage performance will not be reduced due to repeated cycles of drying, freezing and thawing, and possible water leakage will also be caused by the migration of bentonite.
