Sell PAN fiber

Description

Polyacrylonitrile fiber Application- widely used in bituminous pavement and bridge construction, cold-patch and cementation of fissures of the road to protect the project from cracking. Features- 1. enhance the crack resistance of cement concrete effectively- a) the good cohesiveness with concrete makes it have bearing use for the architecture, and prevent the appearance of crack. b) Avoid desiccation fissure by adjusting moisture content. c) Reduce fissures by adjusting heat-release or other temperature change. 2. Improve anti-permeability and freezing resistance of concrete, increase its durability. a) The fiber can highly reduce the size and quantity of pore in the concrete, and improves the anti-permeability and freezing resistance of concrete. The frequency of freezing resistance of concrete is up to **0 times. 3. Lower the brittleness of concrete and prevent the crack from widening. 4. Improve the stability of concrete under high temperature. 5. Improve the tensile strength, shear strength and crack resistance under low temperature. 6. Improve the antifatigue and durability of concrete. 7. Improve the moisture stability and toughness of concrete. 8. Improve the abrasive resistance and anti-strip feature of the concrete.
