聚丙烯短纤维特点
Characteristics of polypropylene staple fibers
1.较高的强度和弹性模量，有利于混凝土的力学性能。
1. Higher strength and elastic modulus are beneficial to the mechanical properties of concrete.
2.与水泥表面握裹力强，亲水性处理利于挂灰，提高强度。
2. Strong bonding force with cement surface, hydrophilic treatment is conducive to hanging ash and improving strength.
3.分散性极佳，不抱团，有效保证其防裂性能的发挥。
3. Excellent dispersion, no clump, effectively ensure the performance of crack prevention.
4.纤维化学性能稳定，耐酸碱性极强。
4. Fibrosis has stable chemical properties and strong acid and alkali resistance.
对混凝土的增强功能：
Reinforcement function of concrete:
防止砂浆，混凝土的收缩裂缝；改善混凝土的变性我和韧性；增强防渗抗裂性能；提高墙面的抗冲击强度；提高抗剥离性耐磨性；提高抗渗性、冻融性；增强护筋功能；防止砂浆干裂及阻止裂纹扩展。
To prevent shrinkage cracks of mortar and concrete; to improve the denaturation and toughness of concrete; to enhance the anti-seepage and anti-cracking performance; to improve the impact strength of the wall; to improve the anti-peeling and wear resistance; to improve the impermeability, freeze-thaw resistance; to enhance the reinforcement function; to prevent dry cracking of mortar and prevent crack propagation.
