Basalt Fiber

EFP-012

Basalt mineral fiber, using specially selected basalt ore as raw material, after specific pretreatment, melting at 1500 °C high temperature, refining, and extraction, and after special surface treatment and become. The softening point of basalt fiber is about 1200°C, the appearance of the fiber is smooth and complete, and the safety of use is high. Basalt fiber chopped yarn is a product made of continuous basalt fiber filaments chopped into short pieces. The fibers are coated with a (silane) wetting agent. Therefore, basalt fiber chopped yarn is the preferred material for reinforcing thermoplastic resins, and it is also an excellent material for reinforcing concrete.

The usual dosage is 0.5% of the mass of the mix (PE asphalt soluble sachets).

Increase asphalt viscosity and modulus. Basalt fiber can effectively increase the viscosity and modulus of asphalt, so it can effectively increase the amount of asphalt and asphalt film thickness of asphalt mixture, is an indispensable fiber stabilizer for embedded structure mixture.
Improve high-temperature rutting deformation resistance. Increasing the asphalt viscosity and modulus improves the rutting resistance of various asphalt mixtures. Asphalt mixture dynamic stability increases with the increase in the amount of basalt fiber, basalt fiber can significantly improve the rutting resistance of SMA mixture.
Improvement of low temperature cracking resistance. Basalt fibers can significantly improve the tensile strength and toughness of asphalt mixtures, thereby significantly improving the low-temperature cracking resistance of asphalt pavement.
Improve the water damage resistance of asphalt pavement. Basalt fibers can significantly improve the cracking resistance of asphalt mixture and can prevent water from soaking into the mixture and asphalt, thus preventing early water damage to asphalt pavement and improving water stability.
Improvement of oxidative aging and fatigue durability of asphalt mixtures. Test results show that basalt fibers can significantly reduce the oxidation of asphalt mixtures, and aging and improve fatigue durability, which can be increased up to 400 times. Therefore, basalt fiber improves the fatigue durability of asphalt mixture and a is very effective means of service life.

It has excellent chemical resistance, especially the advantage of alkali resistance, which can improve the high-temperature stability, low-temperature crack resistance, and fatigue resistance of asphalt concrete.
