Polyacrylonitrile Fiber Acrylic Fiber Top For Concrete Buff 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, good dispersibility and oil absorption. In practical application, the combination with the concrete matrix is ​​strong, which improves the cohesion and fatigue resistance of concrete, and enhances the impermeability, frost resistance and impact resistance of concrete. Therefore, it is widely used in asphalt concrete and cement concrete engineering.

1. Adsorb asphalt through viscosification, and increase the asphalt content in the mixture while keeping the viscosity of asphalt mortar unchanged. Adsorption of light oil in bitumen increases the viscosity of the remaining unadsorbed bitumen. The viscosity (flow deformation resistance) of the asphalt mineral powder fiber mixture increases, and the high temperature stability of the asphalt mixture improves.

2. Toughening enhances the binding force between asphalt, cement binder and aggregate surface, prevents spalling and improves water damage resistance. Improve the low-temperature deformation ability and toughness of asphalt mortar and cement mortar, and reduce low-temperature cracking. The fibers play an orientation role in the deformation process of the asphalt mortar, which greatly improves the deformation following ability of the asphalt mixture.

3. The fiber-reinforced asphalt and cement mixture has good fatigue resistance, and its fatigue life is significantly improved. The asphalt and cement mixture containing fiber has good impact toughness, especially suitable for asphalt overlay on old cement concrete pavement. The wear resistance of asphalt and cement mixture mixed with fiber is improved, and it can be used in special places such as anti-skid road surface and crawler vehicle road surface.

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

5. Since it has more characteristics than other fibers, its toughness, impact resistance and crack resistance are further improved in cement concrete and cement products.
