POLYVINYL ALCOHOL FIBER
PRODUCT DETAIL
The high strength and modulus PVA fiber mainly is made of polyvinyl alcohol with the processes of dissolution, spinning, thermoforming, cutting and packing, the PVA can easily and rapidly be mixed into concrete and mortar, and because of its micro appearance and large specific surface area, there is about 30-40 fibers in each cubic centimeters, so it can build the disorderly distributional supporting system, effectively controlling the micro crack caused by the plastic shrinkage and dry shrinkage, effectively preventing the separation of the aggregate, preventing the formation of the sedimentation cracks, greatly improving the anti-permeability and the impact resistance of concrete, greatly improving the toughness and wear resistance, and can taking place of the secondary reinforcement rebar in the concrete.
