Polypropylene fiber and polyacrylonitrile fiber are both synthetic fibers, but there are great differences in practical application.
Polypropylene fiber used in concrete parts can greatly improve the crack resistance and impermeability of concrete. It is an ideal material for mortar and concrete engineering with crack resistance, impermeability, wear resistance and heat insulation.
Polyacrylonitrile fiber is golden in appearance and is usually used in asphalt concrete. As the secondary reinforcement material of concrete, acrylic fiber can obviously improve the toughness and impact resistance of asphalt concrete. And effectively prevent the occurrence and development of cracks. Improve the impermeability, frost resistance and durability of concrete.
In addition, polypropylene fibers are used as industrial fiber products to strengthen asphalt concrete. It can not only improve the adhesiveness, high temperature stability and fatigue durability of asphalt pavement. It has the characteristics of low temperature crack prevention and reflection crack prevention.
Polyacrylonitrile fiber melting point is not so high, heat resistance is not so high, can be added to asphalt, polypropylene can only be added to concrete, mortar.
Each has its own advantages. We can choose more suitable products according to our actual needs.
