Basalt Fiber Chopped Strands


Basalt Fiber

Basalt fiber is a continuous fiber drawn from natural basalt, obtained by high-speed drawing of a platinum-ruthenium alloy wire drawing and draining plate after the basalt rock material is melted at 1450 ° C to 1500 ° C. Pure natural basalt fiber is generally brown in color and has a metallic luster.

Basalt fiber is a new type of inorganic environmentally-friendly green high-performance fiber material composed of oxides such as silica, alumina, calcium oxide, magnesium oxide, iron oxide and titanium dioxide.

Basalt continuous fiber not only has high strength, but also has many excellent properties such as electrical insulation, corrosion resistance and high temperature resistance. In addition, the production process of basalt fiber determines that the waste generated is small, the environmental pollution is small, and the product can be directly degraded in the environment after being discarded, so it is a veritable green and environmentally friendly material.

China has listed basalt fiber as one of the four major fiber developments (carbon fiber, aramid, UHMWPE, basalt fiber), and has achieved industrial production. Basalt continuous fibers have been widely used in fiber reinforced composites, friction materials, shipbuilding materials, thermal insulation materials, automotive industry, high temperature filter fabrics and protection fields.

Chopped Strands

The basalt fiber chopped Strand is a product obtained by chopping continuous basalt fiber yarns. The fiber is coated with a (silane) sizing agent.

-Therefore, basalt fiber chopped yarn is the material for reinforcing thermoplastic resin systems, and is also the best material for reinforced concrete. Basalt is a high-performance volcanic rock component. This special silicate gives basalt fiber excellent chemical resistance, especially alkali resistance.

-Basalt fiber is an ideal material for reinforcing cement concrete instead of polypropylene (PP) and polyacrylonitrile (PAN); it is also a competitive product for asphalt concrete, such as polyester fiber and lignin fiber, which can be improved. High temperature stability, low temperature crack resistance and fatigue resistance of asphalt concrete.
