                Application of alumina fiber

                The new material industry is one of the ten strategic emerging industries in China and one of the ten major areas of development of "Made in China 2025", and the key area in the "Thirteenth Five-Year Plan" National Science and Technology Innovation Plan.

                Due to the outstanding product advantages of alumina fiber needle punched carpets, the core manufacturing technology has been tightly sealed by developed countries, and China has long relied on imports for this product. A very large application market for alumina fiber needle punched blankets is the three-way catalyst sealing gaskets in high-end automotive industry exhaust treatment equipment. At present, the sealing gaskets in the automotive industry are monopolized by companies such as Mitsubishi, IBIDEN, and 3M in the United States. In addition, alumina continuous fibers can be processed into alumina yarns and alumina fiber cloths, which are materials for high-temperature and fire-resistant fields such as aerospace and defense industries.

                The successful development of alumina fiber needle punched blankets has solved the key equipment problems restricting the alumina fiber industrialization, realized the alumina fiber industrialization and localization, broke the technical blockade of European and American countries, provided key materials for the military industry, and promoted Significant development of aerospace and military industries has laid a solid foundation; upgrading of China's high-tech inorganic fiber manufacturing technology has led to major breakthroughs in high-tech fiber industries such as zirconia and silicon carbide; reducing domestic companies' procurement costs of alumina products, saving the country A lot of foreign exchange funds.
