Polypropylene fiber Storage method and environment of silk
Polypropylene fiber prevention mortar Shrinkage crack
◆ Improve the impact strength and peel resistance of the wall
◆ Improve the abrasion resistance of the wall
◆ Improve the impermeability of the wall
◆ Improve freeze thaw resistance
◆ Enhance the rebar protection function
◆ Prevent mortar from drying and crack propagation
◆ Replacement (for plastering) hardware cloth Road concrete polypropylene fiber, also known as engineering fiber
Concrete fiber, crack resistant fiber, crack resistant fiber or synthetic fiber, plastic fiber, etc,
It is a kind of high degree bundle fiber made of polypropylene as the main raw material and unique production process. Adding it into concrete or mortar can effectively control the micro cracks caused by factors such as solid plastic shrinkage, dry shrinkage and temperature change of concrete (mortar), prevent and suppress the formation and development of cracks, and greatly improve the crack resistance and impermeability, impact resistance and seismic resistance of concrete, It can be widely used in various applications of bridge deck and pavement (highway and airport runway) overlay, mining and tunnel engineering, * * *, high-rise buildings, slope fixation, fire prevention facilities, concrete repair, roofs of industrial and civil construction projects wall Waterproof works of basement, pool and roof garden, various precast concrete products, etc.
