What is the mechanism of action of polypropylene engineering fibers?

The raw material of polypropylene engineering fibers are pure polypropylene, with special additives, it is resistant to acid and alkali salts, polypropylene engineering fiber in the manufacturing process, special static electricity and anti-ultraviolet treatment, so that the fiber is in concrete mortar It is non-agglomerated and evenly distributed, and has the characteristics of anti-ultraviolet aging to ensure long-term performance in concrete and thermal insulation mortar.

polypropylene engineering fibers are very chemically stable and do not absorb other substances and produce chemical reactions. Polypropylene engineering fiber is mainly used to change the physical properties of concrete and mortar, and has excellent compatibility with cement coarse and fine base materials and other admixtures.

When the polypropylene engineering fibers are blended into the cement base material, the crack resistance is increased by 1.2 times or more. In the case of reasonable ratio and construction examples, the occurrence of gaps can be completely prevented. Incorporating into concrete or mortar, it can extremely effectively control the gap caused by plastic shrinkage cracking or temperature changes of concrete or mortar, prevent and inhibit the growth of cracks, and improve the impermeability and crack resistance of concrete. The addition of polypropylene fiber can also greatly improve the crack resistance and impact resistance of concrete or mortar, resist abrasion, freeze-thaw resistance, and eliminate plastic settlement and cracking.
