After the Spring Festival, chemical fiber enterprises are slowly on the right track, and Hai'an County Qinfeng Chemical Fiber Co., Ltd. has also been put into normal work. As a professional manufacturer of polypropylene staple fiber, about the performance of polypropylene staple fiber, Qinfeng can be said to be full of economy.

polypropylene staple fiber type: bundled monofilament, general specifications: 3mm, 6mm, 9mm, 12mm, specific gravity: 0.9, tensile strength: >400Mpa, acid and alkali resistance: high, elastic modulus: >3.5Gpa, melting point: About 160 ° C, fiber diameter: 48 um, thermal conductivity: low, ignition point: about 580 ° C, humidity: <0.1%, safety: non-toxic materials, low temperature resistance: -78 ° C.

Anti-aging: The fiber has undergone special anti-aging treatment.

Application of polypropylene staple fiber in engineering

polypropylene staple fiber can be widely used in pouring concrete and shotcrete engineering such as water conservancy hubs, hydropower stations, ports, wharves, rivers, concrete dams, spillway, diversion tunnels, embankment reinforcement, slope reinforcement, dam surface repair, etc. The roof and basement of Fangjianzhong are resistant to cracking and waterproofing, the cracking of the slabs and columns and beams, the cracking of the mortar on the inner and outer walls, the seismic and impact resistance of the floor of the plant, the explosive parts and the repair of the building. Airports, municipal facilities, roads, bridges, etc. are often impacted by concrete structures and GRC products, European-style components, art sculptures, lightweight wall panels, pre-mixed mortar and so on.

polypropylene staple fiber can improve the crack resistance, impermeability, anti-wear, anti-freezing ability, anti-explosion ability and improve the workability of concrete. Tens of millions of fibers are evenly distributed in the mortar/concrete, which plays a very good role in micro-reinforcing, which keeps the integrity of the structure well and prevents the structure from being scattered into many fragments when it is damaged by impact. Corrosion of steel bars in the structure can greatly extend the service life of the project and reduce the maintenance cost of the project.

The polypropylene staple fiber content is 0.6-1.8 kg/m3 mortar or concrete, generally 0.9 kg/m3 mortar or concrete. According to the local area of the engineering site, the amount of fiber should be different. For the area where the freeze-thaw is more harmful and the amount of the burned part should be higher.

Hai'an County Qinfeng Chemical Fiber Co., Ltd. relies on the professional power of single flow, the front-end quality inspection system and perfect quality inspection system ranks among the high-quality enterprise queues in the industry, specializing in the production of polypropylene staple fiber, and the "Qinfeng" brand polypropylene staple fiber has superior guidance. Wet and fast drying, good combability and spinning performance, with fast melting, good filling and sound insulation.
