As one of my country’s seven strategic emerging industries and one of the ten key development areas of "Made in China 2025", the new material industry is a key area in the "13th Five-Year Plan for National Science and Technology Innovation", which is the industrial basis for the transformation and upgrading of the entire manufacturing industry. .

　　 Due to its outstanding product advantages, the core manufacturing technology of alumina fiber needle-punched blanket has been tightly sealed by developed countries, and my country has long relied on imports for this product. A very large application market for alumina fiber needle-punched blankets is the three-way catalytic converter sealing gasket in the exhaust gas treatment equipment of the high-end automobile industry. At present, the sealing gaskets in the automobile industry are monopolized by companies such as Japan's Mitsubishi, Japan's IBIDEN, and the United States 3M. In addition, alumina continuous fiber can be processed into alumina yarn and alumina fiber cloth, which is a material in high-temperature refractory fields such as aerospace, national defense and military industry. The successful development of the alumina fiber needle-punched blanket has solved the key equipment problem restricting the industrialization of alumina fiber, realized the industrialization and localization of alumina fiber, broke the technical blockade of European and American countries, provided key materials for the military industry, and promoted The major development of aerospace and military industries has laid a solid foundation; the upgrading of my country’s high-tech inorganic fiber manufacturing technology will drive major breakthroughs in the high-tech fiber industry such as zirconia and silicon carbide; reduce the purchase cost of alumina products for domestic enterprises and save the country Large amounts of foreign exchange funds.
