What are the characteristics of waterproof polypropylene non-woven fabrics

The characteristics of waterproof polypropylene non-woven fabrics, why thin waterproof polypropylene non-woven fabrics can be waterproof, I believe that my friends have a lot of questions, the author will tell you the reasons below, first look at the characteristics of waterproof polypropylene: 　　1, three layers Structure, surface enhancement 2. The core layer-the main waterproof layer uses linear low-density polyethylene (LLDPE) with a higher branch ratio (more macromolecular side chains), which is extensible, impermeable, soft, and resistant. Good penetration and low temperature resistance.　　3. The surface is polypropylene (polyester) non-woven fabric, which solves the problem of large linear expansion coefficient of polyethylene by compounding with the core layer. The surface roughness of the product is increased, the friction coefficient of the product is improved, and the bonding problem of the composite coil is solved, and cement bonding is realized. Structural characteristics of water-removing polypropylene non-woven fabric: 　 has strong impermeability, high tensile strength, good low temperature flexibility, small linear expansion coefficient, easy bonding, large friction coefficient, good stability, non-toxic, strong deformation adaptability, adaptability Good comprehensive technical performance such as wide temperature range and long service life. Polyethylene and polypropylene (polypropylene) are chemically stable, resistant to corrosion, mildew, and ozone, while polypropylene has good mechanical properties. In addition to the characteristics of the use of water polypropylene non-woven fabrics: 　　 1. The polymer waterproof membrane belongs to the series of polymer waterproof membranes. In addition to fully having all the advantages of synthetic polymer membranes, its own most prominent feature lies in its surface The net structure gives it its own unique performance-cement bonding.　　2. Because the polymer composite coil can be directly bonded with cement, it will not be affected by the moisture content of the base layer during the construction process, and it can be constructed as long as there is no clear water. This is not available in other waterproof membranes.　　3. Due to the rough surface of the polymer composite coil and the large friction coefficient, it can be directly buried in sand and has sufficient stability when applied in water conservancy projects.　　4. Because the polymer composite coil can be directly bonded to the cement material during the solidification process, it can be directly designed in the structure of the cement material.　　Quanzhou Nonwovens Co., Ltd. is a professional manufacturer of environmentally friendly nonwovens, with a complete and scientific quality management system.
