What is the basis of the material for the formation of nitride bonded silicon carbide?
- Nov 29, 2018 -

Nitrogen bonded silicon carbide products need to be widely used in various industries, such as powdering, crushing, grading, dust removal, filtration, sedimentation, centrifugation, drying, crystallization, mixing, transportation, feeding, packaging, etc. The basis for the production of materials - silicon carbide waste, silicon carbide waste powder technology is the most important branch of the powder and particle process.


Silicon carbide waste pulverization technology is divided into two categories, one of which is the forming process. The main feature of this method is that the powdered silicon carbide waste is processed into a specific shape that meets the market needs through specific equipment and methods. Bulk-packed silicon carbide waste required for composition, density, etc. The second method is the particle size increasing method. The main feature of this method is that it can agglomerate the fine powder into coarser particles.


In order to meet the requirements of China's silicon carbide waste pulverization and nitrogen-carbon bonded silicon carbide products, wet pulverization can be used, which is made by mixing silicon carbide waste and fluid binder to produce finished products or semi-finished granules. This method can increase the density of the particles, make the silicon carbide waste easier to be controlled, and has good fluidity, compressibility, stability, and wettability, and can achieve no agglomeration, no foam, and easy dispersion.


You can also use the hot melt molding method, which mainly utilizes the low melting point of the product, and condenses and crystallizes the molten silicon carbide waste into a desired sheet, strip, block, hemisphere, etc. by special condensation method. It lays a good foundation for the production of nitrogen bonded silicon carbide products.
