olypropylene short fiber is a kind of strong bundle monofilament fiber made from polypropylene with a unique production process. Adding it into concrete mortar can effectively control the micro cracks caused by solid plastic shrinkage, dry shrinkage, temperature change and other factors of concrete mortar, prevent and slow the formation and development of cracks, and greatly improve the crack resistance, impermeability, impact resistance and seismic resistance of concrete It can be widely used in various mortars, underground waterproof works, walls, floors, cement, basements, roads and bridges. Performance of polypropylene in dry powder mortar or concrete 1. It is evenly dispersed in the mortar to form a three-dimensional disordered structure inside, and can lock the moisture inside the mortar, with strong grip and wrapping force; 2. It is not easy to agglomerate in mortar or concrete, which effectively ensures the play of its crack prevention performance. It is convenient to use, without changing the mortar ratio. Put the fiber into the mortar mixture and add water to mix evenly; 3. In the concrete, the wear resistance, impermeability, freeze-thaw resistance of the concrete are improved, and the reinforcement protection function is enhanced; 4. The fiber has stable chemical properties, strong acid and alkali resistance, and can be used in any project.
Fiber type: bundle monofilament density: 0.91/g/cm3 equivalent diameter: 18~48 tensile strength:≥500MPa modulus of elasticity:≥3850mpa elongation at break: 10-28% acid and alkali resistance: very high melting point: 160~180℃ignition point: 580℃length: 3, 6, 9, 12, 5, 54mm advantages of short fibers in mortar improve the impermeability of mortar▲improve the toughness of cement mortar, Relieve fatigue and abrasion resistance▲improve crack resistance▲improve the durability of cement mortar▲improve the resistance of cement mortar to freeze-thaw damage
