The carbon graphite rings used in mechanical seals. During the sintering process, there will be pyrolysis substances and pores discharged, and the porosity, calculated by volume, accounts for approximately 10% to 30%. This porous carbon graphite ring cannot be used as a mechanical seal ring. Therefo
Graphite material is widely used, but it is not suitable for all industrial applications. For example, the environment for smelting scrap iron requires the addition of strong alkali substances. Graphite has very limited tolerance to strong alkali and consumes too quickly. At this time, specialized materials are needed. As a supplement, our company provides special alkaline material smelting solutions. At the same time, we provide guidance on the use of alumina crucibles and graphite crucibles.
In order to better serve customers and achieve one-stop purchasing, with many years of industry experience, our company also provides peripheral products for graphite product applications, such as crucible tongs, insulation cotton, various furnaces, etc.
