This production line uses polypropylene as the main raw material, adds modifiers, and uses a unique process to produce polypropylene monofilament fibers. Its production process includes polypropylene single-screw extruder, melt filtration, melt metering, spinning, cooling, seven-roller drawing, heating oven, cutting, and packaging finished products.
Polypropylene fiber reinforced wire can significantly improve the toughness and impact resistance of concrete, effectively prevent the generation and development of cracks, and improve the durability of concrete such as impermeability and frost resistance. In addition, as an industrial fiber product for strengthening asphalt concrete, it can not only greatly improve the adhesion, high stability and fatigue durability of asphalt pavement, but also have the properties of high temperature crack resistance and reflection crack prevention, effectively improving tensile and shear resistance. , compressive and impact strength. His great role and prospects in concrete have been more and more recognized and accepted by the engineering community.
