Waterproof mechanism of waterproof blanket
The permanent waterproof performance: because sodium bentonite series natural inorganic material, even after a long time or the surrounding environment changes, also does not occur, aging or corrosion, therefore durable waterproof performance.
Construction is simple: compared with other waterproof materials, the construction is relatively simple, without heating and pasting. Only with bentonite powder and nails, gaskets and other connections and fixed. No special inspection is required after construction, and it is easy to repair if water proof defects are found. GCL is the shortest construction period in existing waterproof materials.
Swelling of bentonite particles in the water, so as to form a colloidal system in uniform, two layers of geotextile restrictions under the action of the bentonite from disorder into order expansion, continued expansion with the result that bentonite self compacted, thus having waterproof function. 1. density: high density diaphragm sodium bentonite formation in the hydraulic condition, the thickness of about 3mm, permeability of it is 5 x 10 - 11m/s, the compactness of 30cm is equivalent to 100 times the thickness of clay, has a strong self water performance.
