Basalt fiber properties, basalt fiber use, BF is the abbreviation of basaltfiber

 

　　Basalt fiber is a continuous fiber made of basalt stone after melting at 1450 ℃ ~ 1500 ℃ and high speed drawing by platinum rhodium alloy wire drawing leakage plate. Similar to glass fiber, its performance is between high strength s glass fiber and alkali free E glass fiber. The color of pure natural basalt fiber is generally brown, some like gold.

 

　　Properties of basalt fiber and application of basalt fiber

 

　　Basalt fiber products are:

 

　　1. Basalt fiber roving is a basalt fiber product made by combining multiple parallel or single parallel raw wires in a non twisted state,

 

　　2. Basalt fiber textile yarn is a yarn made of several basalt fiber raw wires twisted and combined. The diameter of single wire is generally ≤ 9 μ M. The textile yarn can be divided into weaving yarn and other industrial yarn; Weaving yarn is mainly pipe yarn and milk bottle shaped bobbin yarn.

 

　　3. Basalt fiber short cut yarn is a product made by short cutting of continuous basalt fiber raw wire. The fibers are coated with (silane) wetting agent. Therefore, basalt fiber short cut yarn is the first choice for strengthening thermoplastic resin, and also the best material for reinforced concrete. Basalt is a kind of high-performance volcanic rock component, which makes basalt fiber have excellent chemical resistance and alkali resistance. Therefore, basalt fiber is a good material for reinforcing cement concrete instead of polypropylene (PP) and pan; It is also a competitive product for asphalt concrete, such as substitute polyester fiber and lignin fiber, which can improve the high temperature stability, low temperature crack resistance and fatigue resistance of asphalt concrete.

 

　　4. Basalt fiber yarn is made by using the high performance expanding yarn machine. The forming principle is: high-speed air flow enters the forming expansion channel to form turbulence. The basalt fiber is dispersed by this turbulence function to form a hairy ring fiber, thus giving the basalt fiber the expansibility and making the expanded yarn.

 

　　5. Basalt fiber cloth

 

　　6. Basalt fiber felt

 

　　7. Basalt fiber composite

 

　　Compared with high-tech fibers such as carbon fiber, aramid fiber, UHMWPE, basalt fiber has the characteristics of high strength and high modulus, and it has excellent performance of high temperature resistance, anti-oxidation, radiation resistance, insulation and sound insulation, good filtration resistance, high compression strength and shear strength, and can be used in various environments, It is a kind of pure natural inorganic non-metallic material, and also a new basic material and high-tech fiber which can meet the development needs of the national economic basic industry.

 

　　Basalt fiber and its composite materials can meet the needs of national defense construction, transportation, construction, petrochemical, environmental protection, electronics, aviation, aerospace and other fields, and play an important role in promoting national defense construction, major projects and industrial structure upgrading. It is not only a green material which meets the requirements of ecological environment in the 21st century, but also a competitive new material industry which can be developed sustainably in the world high-tech fiber industry. Especially, China has owned the technology and technology of basalt fiber manufacturing with independent intellectual property rights, and has reached the international leading level with the advantage of "staying up later". Therefore, it is of great significance to develop basalt fiber and its composite industry.

 

　　8. Basalt fiber is used in functional clothing field: basalt fiber cloth has high strength, permanent flame retardant, short-term temperature resistance of more than 1000 ℃, can be used in 760 ℃ for a long time, and is an ideal material for replacing asbestos and glass fiber cloth. According to the fracture strength of Xuanwu fiber cloth, it has high temperature resistance and permanent flame resistance. It is a low-cost substitute for high-performance fibers and advanced fibers such as Nomex (Aramid 1313), Kevlar (aramid 1414), Zylon (PBO), carbon fiber and other high-performance fibers. Xuanwu fiber cloth can be dyed and printed by chemical printing and dyeing. After functional finishing, such as organic fluorine finishing, it can be made into a permanent flame retardant cloth for oil proof water. Xuanwu fiber cloth can be made of: fire protection clothing, heat insulation clothing, fire avoidance clothing, pre furnace work protective clothing, welding work clothes, and fire retardant clothing for military armored vehicles.
