Precautions For Using Silicon Carbide As Abrasive

Silicon carbide is also known as emery or refractory sand. Silicon carbide is produced by smelting quartz sand, petroleum coke, wood chips and other raw materials in a resistance furnace at high temperature. At present, China's industrial silicon carbide is divided into black silicon carbide and green silicon carbide. Silicon carbide has been recognized by the market in cutting and grinding. Through continuous promotion and use, the application of silicon carbide has been increasingly valued by the market.
The hardness, particle size, particle size, roundness and powder content of silicon carbide powder play an important role in cutting; The application of silicon carbide is also determined by the hardness of raw materials. At the same time, smelting process and smelting time will seriously affect the quality of silicon carbide.
If the hardness of silicon carbide is too hard or too soft, the product will be seriously damaged when using silicon carbide as cutting material. It will lead to the grinding and passivation of silicon carbide particles, which will reduce the cutting force. Causing damage to the product. Therefore, the quality of silicon carbide products should be guaranteed when selecting products.
In addition, in the production of silicon carbide sand and silicon carbide powder, the model and particle size must be uniform. The use of machines or screens is to ensure the uniform particle size of silicon carbide sand, so as to better ensure the quality of products. For example, silicon carbide powder is the most important abrasive in multi-wire cutting of silicon wafers, and is often used to cut hard and brittle materials.
