1.Structure of Bentonite Composite Waterproof Blanket Description:
Waterproof blanket uses a natural grading sodium base bentonite particles and corresponding admixture mixed as raw material, through the acupuncture technology and equipment, fixed bentonite particles between geotextile and plastic woven cloth and blanket made of waterproofing materials. Bentonite waterproof blanket has all the characteristics of geotechnical material, but also has excellent waterproof performance (permeability).
Bentonite waterproof blanket according to the production process can be divided into: acupuncture method of sodium base bentonite waterproof carpet, acupuncture effect of sodium base bentonite waterproof blanket and sodium base bentonite waterproof carpet adhesive method.
2.Main Features of Bentonite Composite Waterproof Blanket:
Excellent waterproof and impervious performance,
All properties of geotextile material, such as separation, reinforcement and protection, filter, etc.
Cost performance is relatively high, a very wide range of aplication.
A width of product can be up to 6 meters,greatly improve the efficiency of construction
