Polypropylene Fiber PP Staple Fiber PP Fiber
Polypropylene staple fiber
Polypropylene fiber is made of polypropylene particles by thermal agent made in the process of continuous process.The fiber through special ultraviolet resistance and anti-static, and processing, make the fiber dispersed evenly in the mortar, can exert its efficacy for a long time.Polypropylene short fiber content of 0.6-1.8 kg/m3 mortar;Average of 0.9 kg/m3 mortar.According to the engineering parts, and different regions, fiber content should be different, to blunt grinding is better place and freezing and thawing is better geographical content should be h

2 Function
Greatly improve the crack resistance of cement mortar
In the mortar, the chaos to the distribution form of fibers can be greatly weakened mortar plastic shrinkage and the stress of freezing and thawing,
Thus extremely effective enhance the toughness of the mortar, inhibits the cracks of fine.
Greatly improve the waterproof impermeability performance of mortar
Fibers were distributed evenly in the mortar interlaced with each other in a large number of filaments have played an important role in the "retainer" aggregate, reduces the mortar on the surface of the drainage and aggregate segregation, in pool, basement engineering, roofing, cisterns, wall plaster, etc., using fiber as waterproof effect is significant, which can effectively solve the seepage problem.
, enhance the ability to resist shock and anti-seismic ability
Join fiber mortar after solidification of bond cement high-strength fibers of adhesion for the density of the random distribution of reticular enhancement system, increase the toughness of the mortar, improve the limit drawing ratio.Mortar impact on fiber absorbs a lot of energy, to enhance the impact resistance of cement mortar and anti-seismic ability.
3. Packing: 20 kg per bag or 25 kg woven bag, within each small bags of 1 kg.
4. Transportation storage: this product transportation should be to prevent the rain.Should be stored in a cool, ventilated warehouse, avoid direct sunlight
