Tens of millions of fibers of polypropylene staple fiber are evenly distributed in mortar/concrete, which plays a good role of micro reinforcement, which well maintains the integrity of the structure, avoids the structure being dispersed into many pieces when it is damaged by impact, prevents the corrosion of the steel in the structure, can greatly extend the service life of the project and reduce the maintenance cost of the project.

Polypropylene staple fiber has the following functions in mortar:

1, crack resistance, prevent the expansion of the original defects in the mortar matrix and effectively delay the appearance of cracks.

2. Anti-seepage: improve the compactness of the mortar matrix and prevent the intrusion of external moisture.

3, durability, improve the mortar matrix frost resistance, fatigue resistance and other properties, improve its durability.

4, impact resistance: improve the mortar matrix deformation resistance, so as to improve its toughness and impact resistance.

5. Tensile strength: The use of fiber can improve the tensile strength of the matrix.

6, high toughness: mortar fiber has high toughness and strength, it is not easy to bend into a ball in the mortar mixing, the appearance of the mesh polypropylene fiber is a network of fiber monofilament interconnecting with each other.

Characteristics of polypropylene staple fiber:

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

2. Strong binding force with cement surface, hydrophilic treatment is conducive to hanging ash, improve strength.

3. Excellent dispersion, no huddle, effectively ensure its anti-crack performance.

4. Stable chemical properties of fiber, strong acid and alkali resistance.

Strengthening function of polypropylene staple fiber to concrete:

Polypropylene staple fiber to prevent mortar, concrete shrinkage cracks; Improve concrete's denaturability and toughness; Enhance anti-seepage and anti-cracking performance; Improve the impact strength of the wall; Improve stripping resistance and wear resistance; Improve impermeability, freeze-thaw property; Enhance the reinforcement function; Prevent dry crack of mortar and prevent crack propagation.

Polypropylene staple fiberuses: Used for anti-crack putty powder, thermal insulation mortar, concrete, construction engineering level, wall, floor, pool, basement, and access bridge engineering, with crack and anti-seepage, wear resistance, improve toughness, improve impact force, explosion-proof, but also with tensile resistance, improve the old interface bonding force.
