PP material synthesized chopped grid crude fiber structure
The invention discloses a chopped grid crude fiber structure synthesized by a PP (polypropylene) material, belongs to the technical field of grid crude fiber structures, and aims to solve the problems that the existing chopped grid crude fiber structure cannot ensure that all the chopped grid crude fiber structure can be dispersed into grids during concrete mixing, and the strength for resisting concrete cracking is limited due to the too small diameter. The fiber grid structure comprises multiple groups of long PP material synthetic fibers and/or short PP material synthetic fibers, and the multiple groups of long PP material synthetic fibers and/or short PP material synthetic fibers are fixedly distributed in a crossed mode to form the fiber grid structure. Therefore, a grid structure is formed before use, a blocky structure is formed through shearing during use, then the blocky structure is mixed with used concrete, grid fibers are distributed in the concrete in a non-overlapping mode or even a small amount of grid fibers are overlapped, dispersed uniformly and not prone to precipitation, and the three-dimensional grid type reinforcing effect is really achieved.
本发明公开了一种PP材料合成短切网格粗纤维结构，属于网格粗纤维结构技术领域，以解决现有的在混凝土搅拌中不能保证全部都能分散为网格，直径过细对抵抗混凝土开裂的力量有限的问题，包括纤维网格结构，所述纤维网格结构包括长PP材料合成纤维和/或短PP材料合成纤维，所述长PP材料合成纤维和/或短PP材料合成纤维均设置有多组，通过多组所述PP材料合成纤维和/或短PP材料合成纤维交叉固定分布形成纤维网格结构，由此使得在使用的前夕即形成了网格结构，在使用的时候经过剪切形成块状结构，然后在与使用的混凝土进行混合，网格纤维在混凝土中分布不重叠或偶有少量重叠分散均匀，不易沉淀，真正做到三维立体网格式加固作用。
