Bentonite gcl
The swelling waterproof blanket is a kind of door Geosynthetics used for anti-seepage of artificial lake waterscape, landfill, underground garage, roof garden, pool, oil depot, chemical storage yard, etc. It is a composite filled with expansive sodium bentonite 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 cannot flow in one direction, and when encountering water, a gelatinous waterproof layer with uniform density will be formed in the pad to prevent water leakage.
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.
