Tens of millions of fibers of polypropylene staple fiber are evenly distributed in the mortar/concrete, which plays a good role of micro-reinforcement, which well maintains the integrity of the structure and prevents the structure from being dispersed into the mortar/concrete. Many fragments prevent the corrosion of the steel bars in the structure, which can greatly extend the service life of the project and reduce the maintenance cost of the project.

Polypropylene staple fiber characteristics: 　　

1. Higher strength and elastic modulus are conducive to the mechanical properties of concrete.

2. It has strong binding force with the cement surface, and the hydrophilic treatment is good for hanging dust and improving the strength.

3. Excellent dispersibility, does not clump, and effectively guarantees its anti-cracking performance.

4. The fiber has stable chemical properties and strong acid and alkali resistance.

The reinforcement function of polypropylene staple fiber to concrete:

Polypropylene staple fiber prevents shrinkage and cracking of mortar and concrete; improves the denaturation and toughness of concrete; enhances seepage and crack resistance; improves the impact strength of walls; improves peel resistance and wear resistance; improves impermeability and freeze-thaw resistance Enhance the function of reinforcing bars; prevent dry cracking of mortar and prevent crack propagation.

Polypropylene staple fiber use: used in anti-cracking putty powder, thermal insulation mortar, concrete, construction engineering levels, walls, floors, pools, basements, and passage bridges. It has anti-cracking, anti-seepage, wear resistance, improved toughness, and improved Impact force, explosion-proof, and resistance to tearing off, improving the bonding force between the new and the old interface.
