Hexagonal Boron Nitride Powder Used For Aluminum Industry
Feb 28, 2022
Boron nitride products are refractory products, it has excellent thermal shock stability, good acid and alkali erosion resistance, can be machined. What are its applications in metal anticorrosion?
In the development of modern industry, metal corrosion has always been concerned. Because of the huge waste of resources caused by metal corrosion every year, people always pay attention to the problem of corrosion prevention. Among many anticorrosion technologies, coating protection has become one of the most commonly used because of its economic and practical application. Because in industrial production, the cause of corrosion is often more than one, anticorrosive coatings often need a variety of materials used together, in order to achieve good anticorrosive effect.
Boron nitride products are also known as "white stone ink", similar to graphite structure, with good thermal conductivity, lubricity and high temperature resistance. Unlike graphite, hexagonal boron nitride products have electrical insulation, and because of their chemical resistance, hexagonal boron nitride products are ideal for use as components of anticorrosive coatings in the field of coating anticorrosion.
The anticorrosion mechanism of anticorrosive coating is that boron nitride dispersed in the coating expands the diffusion path of corrosive medium, effectively prevents the infiltration of water molecules, ions and oxygen, and delays corrosion. At the same time, soluble conductive polymers can form dense passivation films on multiple metal surfaces, effectively preventing the corrosion of metal surfaces.
