characteristic:
Compared with high-tech fibers such as carbon fiber, aramid fiber, and ultra-high molecular weight polyethylene fiber (UHMWPE), basalt fiber has the characteristics of high strength and high modulus of high-tech fiber, and basalt fiber also has good high temperature resistance and oxidation resistance. , radiation resistance, heat insulation and sound insulation, good filterability, high compressive strength and shear strength, suitable for use in various environments and other excellent performance, and cost-effective, is a pure natural inorganic non-metallic material, is also a kind of New basic materials and high-tech fibers that meet the development needs of basic industries in the national economy.
Basalt fiber and its composite materials can better meet the needs of structural materials in the fields of national defense construction, transportation, construction, petrochemical industry, environmental protection, electronics, aviation, aerospace and other fields, and play an important role in national defense construction, major projects and industrial structure upgrading. effect. It is not only a green material that meets the requirements of the ecological environment in the 21st century, but also a competitive new material industry that can sustainably develop in the world's high-tech fiber industry. In particular, my country already has the basalt fiber manufacturing technology and process with independent intellectual property rights, and has reached the international leading level with the post-development advantage of "come from behind". Therefore, vigorously developing the basalt fiber and its composite material industry is undoubtedly of great significance.
Application in the field of functional clothing
Basalt fiber cloth has high strength, permanent flame retardancy, short-term temperature resistance above 1000 °C, and can be used in a long-term temperature environment of 760 °C. It is an ideal material to replace asbestos and glass fiber cloth. According to the basalt fiber cloth, it has high breaking strength, high temperature resistance and permanent flame retardancy. It is a low-cost alternative to high-performance fibers and advanced fibers such as Nomex (Aramid 1313), Kevlar (Aramid 1414), Zylon (PBO fiber), and carbon fiber. The basalt 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 oil and water resistant permanent flame retardant cloth. The clothing that basalt fiber cloth can manufacture includes: firefighter protective clothing, heat insulation clothing, fire protection clothing, protective clothing for furnace workers, electric welding overalls, and flame retardant clothing for military armored vehicle crew members.
