Aluminum Silicate Needle Blanket Details
The thermal conductivity of the aluminum silicate needle blanket is slightly larger than that of air. Because the aluminum silicate blanket is composed of a mixed design of solid fibers and air, the porosity is as high as more than 90%. A lot of low thermal conductivity air is filled in the pores and destroys the The continuous network layout of solid molecules results in excellent thermal insulation properties. Moreover, the smaller the pore diameter and the greater the number of closed pores cut by solid fibers along the direction of heat flow, the better the thermal insulation performance of the high-aluminum aluminum silicate needle-punched blanket.
1. High Temperature Resistance:These blankets can withstand extremely high temperatures, typically up to 2300°F (1260°C) or higher.
2.Lightweight and Flexible: Aluminum silicate needle-punched blankets are lightweight and flexible, allowing for easy handling, cutting, and installation in various shapes and sizes.
3.Easy Installation:These blankets are easy to cut, shape, and install, allowing for quick and efficient insulation of various industrial equipment, furnaces, boilers, and pipes.

1. Industrial Furnace and Kiln Insulation:These blankets are extensively used for lining and insulating high-temperature industrial furnaces, kilns, and ovens in industries like steel, glass, ceramics, and cement manufacturing. They help conserve energy by minimizing heat loss and maintaining high temperatures within these units.
2. Boiler Insulation:In thermal power plants and other facilities with boilers, ceramic fiber blankets are employed for insulating boilers, steam pipes, and other components to enhance thermal efficiency and safety.
3. Petrochemical and Refining Industry:They are used for insulating equipment such as reactors, heaters, and pipelines in the petrochemical and refining industry where high temperatures and thermal insulation are crucial.
4. Foundries and Metal Processing:Aluminum silicate needle-punched blankets are utilized to insulate ladles, tundishes, and other equipment in foundries and metal processing industries, where they help maintain high temperatures and prevent heat loss during metal casting and processing operations.
Semi-silica brick refers to an aluminum-silicon refractory product with a SiO2 content of greater than 65% and an Al2O3 content of 15% to 30%. They generally use clay containing quartz impurities or native kaolin refractory clay or tailings and pyroph...
The Al2O3 content of anchor bricks is above 55%, and some users require that the alumina content reach 75%, and the load softening temperature of 75% bricks reaches 1550C. However, in actual use, anchor bricks with high aluminum content cannot be enough. The key is Flexibility is the most important t...
