Polypropylene stabilized fiber

Polypropylene staple fiber is a kind of strong monofilament fiber made of polypropylene with unique production process. Adding it to concrete mortar can effectively control the microcracks caused by factors such as solid plastic shrinkage, dry shrinkage and temperature change of concrete mortar, prevent and slow the formation and development of cracks, greatly improve the crack resistance, impermeability and impact resistance. The seismic resistance and seismic resistance of concrete can be widely used in various mortar, underground waterproof works, walls, floors, cement, basements, roads and bridges. Properties of polypropylene in dry mortar or concrete 1. It is evenly dispersed in mortar, forming a three-dimensional disordered structure inside, which can lock the moisture inside the mortar, and has strong grip and wrapping force; 2. It is not easy to agglomerate in mortar or concrete, effectively ensuring its crack prevention performance. It is convenient to use without changing the mortar ratio. Put the fiber into the mortar mixture, add water and mix evenly; 3. In the concrete, the abrasion resistance, impermeability, freezing and thawing 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. The freezing thawing resistance of concrete is 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.
