Polyacrylonitrile Concrete Reinforcing Reinforcement PAN Polyacrylonitrile Fiber

Product properties:

PAN fiber has higher tensile strength, higher initial modulus and stable chemical properties than other fibers. Therefore, the fiber has acid and alkali corrosion resistance, light resistance, weather resistance, and good dispersion, oil absorption. After mixing concrete and polyacrylonitrile fiber, a three-dimensional random support system is formed, which reduces the shrinkage force of concrete and the cracking of concrete caused by the plastic shrinkage of cement paste. Some cracks will appear in the drying process of cement concrete, and the concrete mixed with polyacrylonitrile fiber can effectively prevent the continuous diffusion of cracks caused by dry shrinkage and plastic deformation. The real function and application prospect of polyacrylonitrile fiber in concrete have been recognized and accepted by the engineering community.

Specifications:

Application of the cement concrete:
1. Cement products, such as precast concrete panel and component
2. Cement concrete road, pavement, bridge deck, airfield runway
3. Port, sea terminal, bridge and cold region engineering
4. Highway anti impact retaining wall, anti impact damper
5. Pool, swimming pool, sewage treatment pond
6. Slab dam in hydraulic project and hydroelectric project
7. Basement wall, floor, roof, floor and other waterproof engineering
8. Shotcrete and pumping

9. In terms of the shrinkage of concrete, the addition of polyacrylonitrile fiber can significantly reduce the shrinkage of concrete.

Application of the asphalt concrete:
1. The overlay of old and newly built asphalt pavement
2. Pavement mending
3. The cold asphalt concrete pavement, cementation of fissures
4. The distribution of polyacrylonitrile fiber controls the plasticity of cement concrete materials, undertakes the shrinkage stress and toughness of local concrete, and effectively controls the diffusion of fine cracks in concrete.

5. polyacrylonitrile fiber has high elastic modulus, which increases the plastic strength of concrete crack resistance.
