Basalt fiber, is a continuous fiber made of basalt stone molten at 1450℃～1500℃ and pulled by platinum-rhodium alloy drawing funnel at high speed, the strength is comparable to high strength S glass fiber. The color of pure natural basalt fiber is generally brown, some resembling gold.
contact us's chemical composition is similar to gabbro or gabbro, SiO2 content varies between 45% and 52%, K2O+Na2O content is slightly higher than intrusive rocks, CaO, Fe2O3+FeO, MgO content is slightly lower than intrusive rocks. The mineral composition is mainly composed of basic feldspar and pyroxene, with secondary minerals such as olivine, hornblende and black mica, etc. The rocks are all dark, generally black, sometimes gray-green and dark purple. The rocks have a mottled structure. The pore structure and almandine structure are common.
Basalt fiber, is a continuous fiber made of basalt stone molten at 1450âï½1500â and pulled by platinum-rhodium alloy drawing funnel at high speed, the strength is comparable to high strength S glass fiber. The color of pure natural basalt fiber is generally brown, some resembling gold.
Basalt fiber is a new type of inorganic environmental protection green high performance fiber material, which is made of basalt stone composed of oxides such as silica, alumina, calcium oxide, magnesium oxide, iron oxide and titanium dioxide, etc. After melting at high temperature, it is quickly drawn through the funnel plate. 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 decides to produce less waste, less pollution to the environment, and the product can be directly degraded in the environment after disposal, without any harm, so it is a veritable green, environmentally friendly materials.

Basalt fiber has good tensile strength and reinforcing effect, high corrosion resistance and chemical stability, good insulation performance, high temperature resistance and low temperature thermal stability, high elastic film amount and heat and sound insulation performance and other properties. Especially, the fiber surface can be significantly improved by oxidation modification technology, chemical plating/electroplating surface modification technology, plasma modification technology and coating modification technology, which can significantly improve the surface chemical stability, adhesion performance, carrier surface energy, bioaffinity, etc.
China has listed basalt fiber as one of the four major fibers (carbon fiber, aramid, ultra-high molecular weight polyethylene, basalt fiber) to be developed and realized industrial production. At present, it is widely used in road civil construction, energy-saving and environmental protection, aerospace, military equipment, automobile shipbuilding and other fields.
Basalt ore in China is widely distributed, and has a good quality, which provides a relatively rich raw material for the production of high-quality basalt fiber. The basalt fiber also has many excellent properties that many fibers cannot have, so it is important to strengthen the research on basalt fiber, especially the research on the process.
We are sure that our basalt fiber will satisfy your requirements. If you need basalt fiber, please feel free to contact us.
