Polyacrylonitrile Fiber Acrylic Fiber Top For Concrete Light Yellow PAN Fiber Competitive Price

Acrylic 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 has good dispersibility and oil absorption. In practical applications, the bonding force with the concrete matrix is ​​strong, which improves the cohesion and fatigue resistance of the concrete, and enhances the impermeability, frost resistance and impact resistance of the concrete. Therefore, it is widely used in asphalt concrete and cement concrete engineering.

1. Adsorb asphalt through viscosifying effect, and increase the asphalt content in the mixture while keeping the viscosity of asphalt mortar unchanged. The adsorption of light oil in the bitumen increases the viscosity of the remaining unadsorbed bitumen. The high temperature stability of the asphalt mixture increases with the viscosity (resistance to flow deformation) of the asphalt mineral fiber mixture.

2. Toughening enhances the bonding force between asphalt, cement binder and aggregate surface to prevent spalling and improve water erosion resistance. Improve the low temperature deformation ability and toughness of asphalt mortar and cement mortar, and reduce low temperature cracking. Fibers play an orientation role in the deformation process of asphalt mortar, which greatly improves the deformation following ability of asphalt mixture.

3. The fiber-reinforced asphalt and cement mixture has good fatigue resistance, and the fatigue life is significantly improved. Fiber-containing asphalt and cement mixtures have good impact toughness and are especially suitable for asphalt overlays on old cement concrete pavements. It improves the wear resistance of asphalt and cement mixture mixed with fiber, and can be used in special places such as anti-skid pavement and tracked vehicle pavement.

4. The volume of asphalt adsorbed by most fibers expands slightly after filling, which can effectively reduce the voids of asphalt pavement, reduce the size of voids, and improve the uniformity of void distribution. The use of water-enhancing fibers can improve the bleeding ability of asphalt mixture, shorten the residual time of water in asphalt pavement, and reduce water damage.

5. Because it has more properties than other fibers, it further improves its toughness, impact resistance and crack resistance in cement concrete and cement products.
