What are the application areas of polypropylene engineering fibers?
polypropylene engineering fiberscan improve its crack resistance, impact load resistance and flexural resistance in concrete products. Through the stress transmission of polymer fiber, it can effectively control and reduce crack generation and expansion during concrete curing. 3D teeth The strength of the period can be increased by 30%, the tensile strength of the early 3D splitting can be increased by about 10%, the growth rate of the tensile strength is even greater than the tensile strength of the splitting, and the crack resistance is improved by more than 100%.
Mixing polypropylene engineering fibers in concrete products in a certain proportion can also improve the following properties:
1. Improve the anti-freezing effect and cyclic thawing performance of concrete. According to the 0.1% volume of concrete, no anti-freezing agent is added, and the anti-freezing effect increases from D50 to D200.
2. Reduce and eliminate fine cracks on the surface of concrete products, reduce air permeability, contain less than 1.8% gas, 2.6 times lower than without adding the fiber, and at the same time delay the corrosion of concrete to steel.
3. Polypropylene engineering fiber is modified, chemical resistance is good, shrinkage creep is small, and it can be used in special places for acid and alkali resistance.
4. Improve the abrasion resistance of concrete, anti-grinding performance, give concrete products good toughness, extend their service life, and increase the relative anti-wear strength by more than 50%.
5. polypropylene engineering fibers successfully adopts water-soluble small packaging bag, no pollution, no need to recycle, no adverse effect on concrete quality, and it is green packaging. The small bag can be directly put into the concrete mixer for mixing during construction. Polypropylene engineering fiber has good dispersibility in construction, strong gripping force, disordered distribution, automatic reinforcement; simple construction, safe and non-toxic, no magnetic rust, anti-corrosion and alkali resistance, and reliable effect.
6. polypropylene engineering fibers products have a wide range of applications, including water conservancy projects, highway bridges, factories, airports, warehouses, plazas, docks, high-rise buildings, underground buildings, banks and ports.
7. The amount of concrete fiber per cubic meter is 0.8-1.0kg, which can be evenly distributed by stirring in concrete.
Shandong Huimin Zhiwei Chemical Fiber Products Co., Ltd. is located in the Silk Road Industrial Park of Qinghe Town, Huimin County, Shandong Province, which enjoys the reputation of “Hometown of Chinese Rope Nets”. After several years of hard work, it has developed into a production and sales department. Long serviced large polypropylene chemical fiber company.
The polypropylene filament yarn produced by Huimin Zhiwei Chemical Fiber has small color difference, good color fastness and high strength. It is widely used in decorative belts, safety belts, marking lines, etc. It can also produce various special functional wires according to user requirements, such as resistance. Burning, anti-purple, etc.
