Basalt Fiber

Basalt fiber, basalt after 1450 ℃ ~ 1500 ℃ melting platinum and rhodium co-brushed drain board high-speed drawn from a continuous fiber. Similar to the glass fiber, the performance range of high-strength S-glass fibers and E-E glass fibers, natural basalt fiber color is generally brown, some like gold.
 Basalt fiber and carbon fiber, aramid, ultrahigh molecular weight polyethylene fiber (UHMWPE) compared to high-tech fibers, in addition to the characteristics of high-tech fiber high strength, high modulus, basalt fiber also has good heat resistance, anti-oxidation , radiation, noise insulation, filtration, good resistance to compression and shear strength, adapted to the excellent performance of the use of a variety of environments, and cost-effective, is a natural inorganic non-metallic materials, but also a can meet the basic industries of the national economy needs a new foundation materials and high-tech fibers.

Basalt fiber and composite materials can better meet the needs of national defense construction, transportation, construction, petrochemical, environmental protection, electronics, aviation, aerospace and other structural materials in the field of national defense construction, major projects and upgrading the industrial structure has an important boost torole. It is a 21st century green materials to meet the requirements of the ecological environment, but also a sustainable development in the world of high-tech fiber industry competitiveness and new materials industries. Especially basalt fiber manufacturing techniques and technology, China has independent intellectual property rights reached the international leading level, and to "come from behind after development advantages, vigorously develop the basalt fiber composites industry is undoubtedly of great significance.
 Chopped basalt fiber yarn is made of continuous basalt fiber chopped strand products. The fiber is coated with (silane) sizing. Chopped basalt fiber yarn is to enhance the thermoplastic resin material of choice, while still the best material of reinforced concrete. Basalt is a high performance volcanic group, this particular silicate, basalt fiber has excellent chemical resistance, in particular, has the advantages of the alkali resistance. Therefore, the basalt fiber is the alternative to polypropylene (pp), polyacrylonitrile (pan) is used to enhance the fine cement concrete materials; also the alternative to polyester fibers, lignin fibers for asphalt concrete competitive products can be improved high temperature stability of asphalt concrete, the low temperature crack resistance and resistance to fatigue.

       One, the main technical parameters of the basalt fiber
 Basalt fiber is very good chemical stability, thermal stability is also good, strong high-level resistance to hydrolysis folding is also very good, the main technical indicators of the basalt fiber and comparison with the performance of other fibers.

Second, the applications
 1 reinforced thermoplastic resin, is the manufacture of sheet molding compound (the smc, bmc), Bulk Molding Compound (dmc)
 High-quality materials;
 2, suitable for the resin composite used as a reinforcing material of the shells of cars, trains, ships;
 3, is to enhance the cement concrete, asphalt concrete the material of choice for a hydroelectric dam impermeable crack anti
 Pressure and extending the service life of road pavement reinforcing material;
 4, can also be used for heat and power plant condensing tower, nuclear power plant steam cement pipe;
 For high temperature resistant needle felt: Automotive sound-absorbing piece, hot-rolled steel, aluminum tubes, etc.
