Ceramic fibers have the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, low specific heat, and resistance to mechanical vibration. Therefore, their products involve various fields and are widely used in mechanical, metallurgical, chemical, petroleum, transportation, shipbuilding, electronics, and light industry sectors. Their applications in cutting-edge scientific and technological departments such as aerospace and atomic energy are also increasing, improving the thermal performance of industrial furnaces, heating devices, and other thermal equipment, Basic materials for achieving lightweight and energy-saving structures. In recent years, due to the continuous rise in global energy prices and the fact that energy conservation has become a national strategy in China, ceramic fibers, which save 10% to 30% energy compared to traditional refractory materials such as insulation bricks and pouring materials, have been widely used in China, and their development prospects are very promising.

　　Ceramic fibers are mainly used for sealing furnace doors and curtain curtains in various insulated industrial kilns; High temperature flue, lining of air ducts, expansion joints; High temperature insulation and insulation of petrochemical equipment, containers, and pipelines; Protective clothing, gloves, headsets, helmets, boots, etc. in high-temperature environments; The insulation cover of the car engine, the wrapping of the exhaust pipe of the heavy oil engine, and the composite brake friction pad of high-speed racing cars; Sealing fillers and gaskets for pumps, compressors, and valves that transport high-temperature liquids and gases; High temperature electrical insulation; Fireproof joint products such as fire doors, fire curtains, fire blankets, spark pads, and thermal insulation covers; Thermal insulation, insulation materials, and brake friction pads for aerospace and aviation industries; Insulation and wrapping of cryogenic equipment, containers, and pipelines; The thermal insulation and fireproof partitions of important places such as archives, vaults, and safes in high-end office buildings, as well as automatic fire curtains for fire protection.

　　Ceramic fiber has low thermal conductivity, excellent thermal stability, chemical stability, and no corrosion. The brake lining produced with this fiber has good high-temperature resistance and dispersibility, making it suitable for various mixing machines. Suitable for brake linings with high temperature resistance requirements, good thermal recovery performance, and low braking noise. The application fields of ceramic fiber products mainly include the processing industry and heat treatment industry (industrial kilns, heat treatment equipment, and other thermal equipment), with a consumption of about 40%, followed by the steel industry, with a consumption of about 25%. While increasing the production of ceramic fibers abroad, attention has been paid to the development of new varieties. In recent years, in addition to typical ceramic fiber products such as 1000, 1260, 1400, 1600, and mixed fibers, components such as ZrO2 and Cr2O3 have been added to the chemical components of the melt, thereby increasing the maximum service temperature of ceramic fiber products to 1300 ℃. In addition, some production enterprises have successfully developed various new products by adding CaO, MgO and other components to the chemical components of the melt. For example, soluble ceramic fibers contain high-strength ceramic fibers with 62% to 75% Al2O3 and high-temperature resistant ceramic textile fibers. Therefore, the current application of ceramic fibers abroad has brought significant economic benefits, leading to an increasingly expanding range of application of ceramic fibers. The production of ceramic fibers in some major industrialized countries continues to maintain a sustained growth trend, with the development of glassy aluminum silicate fibers being the fastest. Meanwhile, with the continuous expansion of the application scope of ceramic fibers, the production structure of ceramic fiber products has undergone significant changes. For example, the production of ceramic fiber blankets (including fiber blocks) has decreased from 70% of the previous production of ceramic fibers to 45%; The production of ceramic fiber deep processed products (such as fiber ropes, cloth and other fiber products), fiber paper, fiber casting materials, plastic, coating materials and other fiber amorphous materials has significantly increased, approaching 15% of the production of ceramic fibers. The development, production, and application of new varieties of ceramic fibers have greatly promoted the development of application technology and construction methods of ceramic fibers.

　　HX high-strength insulation fiber spraying material has high-strength insulation performance. When used, high-pressure spraying construction method is used to spray processed high-strength spherical fiber velvet, binder, and refractory material onto the attached surface, forming a solid fiber refractory material bonding layer. It has advantages such as high strength, lightweight, personal, and energy-saving, effectively reducing heat loss, preventing furnace shell overheating, and increasing hot air temperature.
