Application of boron oxide as anti-oxidation coating
source：
When using boron oxide as an antioxidant coating, one of the most important problems is to solve the foaming problem. The coating is bonded to the body by adjusting the proportion of the coating, selecting the adhesive and the prepreg. In order for boron oxide to melt at high temperatures, it can be well wrapped on the surface of the graphite carbon block to prevent oxidation.
Under this condition, the graphite carbon block can not be oxidized for a long time at 900 ° C, the coating composition is simple, the preparation is convenient, and the industrial production is easy, thus reducing the electric ji loss, improving the service life, and improving the service life. Saving resources. The anti-oxidation mechanism of boron oxide coating is physical anti-oxidation. In the anti-oxidation process, only physical changes occur, melting from a solid to a liquid, and no other substances are added. It is an excellent antioxidant mechanism. Chemical coating.
Its antioxidant mechanism is mainly due to the melting of boron oxide into a liquid wrapped in graphite at °c, forming a dense glass layer protective film, thereby blocking the entry of oxygen and playing an antioxidant role.
