It can be seen from the above that polypropylene fiber is a non-toxic and harmless safety material, and it will not cause harmful effects on the living environment and health. It meets the requirements of clean and environmental protection of high-tech materials in today's society.
Polypropylene fiber is a specially treated polypropylene monofilament. It is a synthetic fiber spun from isotactic polypropylene obtained by propylene polymerization. Through special surface treatment technology, it ensures that the fiber has good dispersibility in concrete and good bonding force with cement body, and can be used for the resistance of concrete/mortar. Crack seepage control engineering. Moreover, the fiber has the advantages of light weight, high strength, good elasticity, abrasion resistance and corrosion resistance. Adding a certain amount of polypropylene fiber to concrete can improve the crack resistance, impermeability, impact resistance, frost resistance and abrasion resistance of concrete, at the same time improve its toughness and ductility, thereby improving the durability of concrete.
