My factory looking for distributors.
Alumina ceramics is an industrial ceramic material that uses alumina as the main material and is manufactured through a specific process. Because alumina ceramics far outperform traditional metal materials in terms of conductivity, high temperature resistance and mechanical strength, they are popular and recognized.
Ceramic flange sleeve bushing: generally plays the role of positioning, not easy to fall off, sliding, bushing is mainly a protective role, the protection of the shaft and the matrix is not direct wear, general bushing material selection slightly soft material, and the shaft on the wear, wear, bushing can be replaced easily.If bushing is not used, parts are replaced after wear and tear.Now the replacement is the bushing;The price is generally cheaper, easy to process;For the normal application and maintenance of mechanical equipment plays a vital role!
All products through the German DIN standards: DIN43724 / DIN43725 / DIN40680
Alumina ceramics are often further processed into various alumina ceramic parts. Valves are one of them. Although metal valves have been greatly improved through structural and material improvements, they are limited by the characteristics of metal materials and cannot adapt to more and more The requirements of severe working conditions such as high wear and strong corrosion, which in turn show short adaptability life, serious leakage and other problems, greatly affect the stability of system operation.
Because ceramic materials have small thermal deformation, light weight, and have much higher bonding strength than metals, and excellent corrosion resistance, they can better adapt to harsh conditions such as high wear and strong corrosion. Therefore, alumina ceramic valves have replaced metal valves.
