聚丙烯抗裂防渗短纤维是采用纤维级聚丙烯为原料，经特殊工艺加工处理而形成的高强度束状单丝有机纤维，其固有的耐强酸，耐强碱，弱导热性，具有极其稳定的化学性能。加入砂浆或混凝土中可有效的控制砂浆、混凝土在初期塑性收缩阶段中由温度变化等因素引起的微裂缝，防止及抑止裂缝的形成及发展，大大改善混凝土的阻裂抗渗性能，抗冲击及抗震能力，可以广泛的使用于地下工程防水，工业民用建筑工程的屋面、墙体、地坪、水池、地下室，以及道路和桥梁等工程中。是砂浆、混凝土工程抗裂，防渗，耐磨的新型理想材料。
The anti cracking and anti-seepage short fiber of polypropylene is a high strength bundle of monofilament fiber, which is made of fiber grade polypropylene, which is formed by special process and processing. It has strong acid resistance, strong alkali resistance, weak thermal conductivity, and has extremely stable chemical properties. Adding mortar or concrete can effectively control the micro cracks of mortar and concrete in the initial stage of plastic shrinkage, which can prevent and restrain the formation and development of the cracks. It can greatly improve the anti crack and seepage resistance of concrete, the impact resistance and the anti-seismic ability, and can be widely used in the waterproof of underground engineering, roofs, walls and floors of industrial and civil engineering. Such as pool, basement, road and bridge. It is a new ideal material for mortar and concrete engineering, including crack resistance, seepage control and wear resistance.
