Polypropylene Staple Fiber, the "big white" around us!


Polypropylene Staple Fiber is a kind of strength bundle-shaped monofilament fiber which is made of polypropylene as the main raw material and is produced by a unique production process. It can effectively control the solid-plastic shrinkage, shrinkage and temperature change of concrete mortar by adding concrete into mortar. Micro-cracks caused by other factors prevent and inhibit the formation and development of cracks, and greatly improve the crack resistance, impermeability and impact resistance of concrete. Can be widely used in a variety of mortar, underground waterproofing engineering, walls, floors, cement, basement and road and bridge engineering.


When Polypropylene Staple Fibers are blended into concrete, the static elastic modulus is lower than that of ordinary concrete. When thePolypropylene Staple Fiber blending ratio is in the range of 0.05%~0.10%, the change of fiber content does not have much static elastic modulus. The effect, but the fatigue deformation modulus increases with the increase of the admixture. This indicates that Polypropylene Staple Fibers can exert greater effects on the structure under dynamic loading.


Polypropylene Staple Fibers with low modulus of elasticity and high fatigue strength are better at improving the fatigue resistance of concrete. The addition of Polypropylene Staple Fibers in concrete can alleviate the internal stress of concrete caused by temperature changes and prevent the expansion of temperature cracks. According to the concrete antifreeze test method, repeated freeze-thaw cycles, no delamination and cracking . Practice and research have shown that the addition ofPolypropylene Staple Fibers in concrete can be used as an effective concrete temperature compensation for crack resistance, thus improving the frost resistance of concrete.


Polypropylene Staple Fiber use:


Used in anti-cracking putty powder, thermal insulation mortar, concrete, construction engineering level, wall, floor, pool, basement, and access bridge engineering, with anti-cracking, anti-wear, wear resistance, improve toughness, improve impact, explosion-proof, It also has resistance to tearing and improves the bonding between old and new interfaces.


The high strength and elastic modulus of Polypropylene Staple Fiber are beneficial to the mechanical properties of concrete; the grip strength of cement surface is strong, the hydrophilic treatment is good for hanging ash, and the strength is improved; the dispersibility is excellent, and it does not hold the group, effectively ensuring its defense. The performance of the cracking performance; the fiber chemical properties are stable, and the acid and alkali resistance is extremely strong.


PP woven geotextiles made of Polypropylene Staple Fibers with high strength, acid resistance, alkali resistance, antimicrobial resistance, wet and dry strength, etc., can be used for civil works (such as dams, reservoirs, highways, etc.) built on soft soil foundations. Railways, etc., play a reinforcing role, and evenly distribute the load on the geotextile, so that the roadbed is evenly settled and the ground cracks are reduced.


When constructing slopes, woven polypropylene geotextiles can stabilize slopes, reduce slope collapse, shorten construction periods and extend the life of slopes. When carrying a large load, a composite geotextile with a woven geotextile and a nonwoven fabric as a base can be used.Polypropylene Staple Fiber can be used as a filling material for concrete, plaster, etc., to improve the impact resistance, waterproof and heat insulation of concrete.
