The upper and lower surface roughness, non-woven fibers were irregular cross-structure polypropylene polyester, form three-dimensional mesh. You can use long-term stability in the ambient temperature range -40 ℃ ~ 60 ℃. Suitable for bonding a variety of materials, particularly cement material during solidification direct bonding, as long as no clear water can be construction, its good overall performance, high tensile strength. Impermeability ability polypropylene specifications, low temperature flexibility polypropylene Which is good, expansion coefficient of 77 for several hours, easy adhesion and friction coefficient is small, it can be directly set up on sandy soil use, stable and reliable performance. It is a non-toxic, pollution-free green product. mikjnio 4, to improve the frost resistance of concrete. In concrete added polypropylene fibers, can ease the temperature changes caused by the internal stress of the concrete, preventing cracks extended temperature; at the same time, to improve concrete impermeability is also beneficial to improve the ability of anti-freeze. Inhibit the production of the early cracks in the mortar, mainly has the following functions: (1) crack resistance, prevent mortar matrix and expand existing defects effectively delay the appearance of cracks.
