Carbon Black has the advantages of excellent high temperature insulation, high purity, less pollution to heated substances, and less gas generation during use.
However, compared with ceramic insulation materials used at high temperatures below 1600 ° C, it has the disadvantage of easily producing dust to pollute the environment, so that its field of application is limited.
In recent years, the method of adding a layer of glassy carbon film on the surface of specialty carbon black particles has been used to develop high-temperature thermal insulation materials with less dust generation and good fluidity when filling.
It is a spherical porous substance with a diameter of about 0.5~3.0mm, with high particle strength and almost no dust generated by abrasion. Suitable for use in vacuum or resistance heating or high frequency induction furnaces filled with inert gas, up to 3000°C.
This heat insulating material has been applied in the carbon fiber graphitization firing process.
