The difference between composite geomembrane and bentonite waterproof blanket
The products of different materials, bentonite waterproof blanket composed of clay minerals and natural material processing machine, high expansibility and high water absorption capacity, moisture permeability is low; the composite geomembrane material is polyethylene particles by calendering equipment to produce plastic film
Natural bentonite can be divided into two categories: sodium and calcium. Bentonite has the characteristics of water swelling and bentonite waterproof blanket. General calcium bentonite expansion, the expansion of its volume is only about 3 times, while sodium bentonite in water adsorption weight five times of water, the volume expansion to more than 15-17 times the original, the sodium bentonite lock in the middle of the two layers of geosynthetic materials, maintenance and the role of strengthening, so that GCL is the shear strength of a whole.
Different waterproof performance. Composite geomembrane: composite geomembrane composite impermeable membrane is divided into one cloth and two membrane. Tensile, tearing resistance, bursting and other physical and mechanical properties of high index, the product has high strength, good elongation, deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, good performance of seepage control, etc..
