Application of polypropylene staple fiber in engineering

polypropylene staple fiber can be widely used in water conservancy hubs, hydropower stations, ports, docks, rivers, concrete slabs, spillway, diversion tunnels, embankment reinforcement, slope reinforcement, dam surface repair and other concrete and shotcrete projects. 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 plant floor, 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-wearing ability, 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 maintains the integrity of the structure 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 various parts of the project site, the amount of fiber should be different. For the area where the freeze-thaw is more harmful, the amount of the part that is more difficult to burn should be higher.

"Qinfeng" brand polypropylene staple fiber has superior moisture permeability and quick drying property, good combability and spinning performance, and can produce soft and tough fabrics. The fabric is light in weight, warm in warmth, delicate in hand and comfortable to take. , acid and alkali resistant. At the same time, it has the ability to dissolve quickly, good filling and sound insulation.
