The reason of polypropylene non-woven fabric is waterproof

by:Sunshine     2020-09-28
Why do thin waterproof polypropylene non-woven fabric can be waterproof, first take a look at the characteristics of waterproof polypropylene: 1, the three-tier structure, surface strengthening, the core layer - 2 - Main waterproof layer adopted higher than ( Macromolecular side chain) Linear low density polyethylene ( LLDPE) , its extensibility, waterproofness, softness, penetration resistance, good low temperature resistance. 3, the surface of polypropylene ( Polyester) Composite non-woven fabric, with the core layer, solves the large polyethylene linear expansion coefficient. Increased the roughness on the surface of the product, improve the coefficient of friction, and the compound coil bonding problem is resolved, cement bonding was realized. Its structure characteristic: have strong permeability, high tensile strength, good low temperature flexibility, linear expansion coefficient is small, easy to adhesion, friction coefficient, good stability, non-toxic, deformation adaptable, adapt to the wide temperature range, long life and other good comprehensive technical performance. Polyethylene, polypropylene, Polypropylene) All chemical stability, corrosion resistance mildew resistant, resistant to ozone, and polypropylene fiber has good mechanical properties. Its use features: 1, polymer waterproofing materials belong to high polymer waterproofing materials series, which in addition to complete with all the advantages of the synthesis of polymer coil, the most prominent feature of its own, is the surface mesh structure, make its have the use of their own unique performance - - Cement bonding. 2, because of the high polymer adhesive composite cement coil can be used directly, therefore in the construction process is not affected by moisture content at the grass-roots level, as long as no MingShui construction. This is what other waterproofing materials does not have. 3, due to the high polymer composite coil the surface roughness and friction coefficient is big, the water conservancy project applications, can be directly buried in the sand, with sufficient stability. 4, due to the high polymer composite coil can be directly in the process of solidification with cement material bonding, thus can design in the structure of the cement materials directly.
