Alumina Ceramic Part of Insulator
Application Field
Alumina ceramics which are widely using in insulator with high mechanical property、high hardness、long wearing、 large insulation resistance、good corrosion preventive 、high temperature resistant
Alumina ceramics parts also have an important applications in the field of insulation. For example, in the aerospace field, alumina-based fibers can be used to manufacture thermal insulation materials such as heat-resistant tiles and flexible insulation materials on space shuttles, thermal barriers in rocket engines, and insulation materials for high-temperature components in aviation engines.
For other field, alumina ceramics parts can also be used as thermal insulation materials in high-temperature furnaces. Short fiber alumina-based composite materials have the advantages of low density, good insulation, and low heat capacity, which can reduce the weight of high-temperature furnaces a lot and make temperature control more precise, so it can save more energy.
Alumina/resin composite materials also have good insulation performance. This material has the characteristics of elasticity, high hardness, and can be used in the manufacture of sports equipment such as fishing rods, golf clubs, skis, and tennis rackets.
Frankly speaking, the application of alumina ceramics in the field of insulation can help to improve the performance and lifespan of equipment, while also reducing energy consumption. So It will be a positive significance for promoting sustainable development and environmental protection.
