|Precautions for the use of silicon carbide as an abrasive|
|Release time: 2018-4-18|
| Silicon carbide is also called golden steel sand or refractory sand. Silicon carbide is smelted from raw materials such as quartz sand, petroleum coke and sawdust in a high temperature furnace. At present, China's industrial production of silicon carbide is divided into black silicon carbide and green silicon carbide. Silicon carbide has been recognized by the market for cutting and grinding. After continuous promotion and use, the application of silicon carbide has been more and more valued by the market. |
The hardness, grain shape, particle size, circularity and fine powder content of silicon carbide fine powder play a vital role in cutting; the application of silicon carbide is also determined by the hardness of the raw material. Will seriously affect the quality of silicon carbide.
If silicon carbide is too hard or too soft, the product will be severely damaged when using silicon carbide as a cutting material. Will cause silicon carbide particles to be flattened and passivated, resulting in reduced cutting force. Damage to the product. Therefore, the quality of silicon carbide products must be guaranteed when selecting products.
In addition, in the production of silicon carbide sand, silicon carbide fine powder, model, particle size must be uniform, the use of machinery or screens are to ensure that the particle size of silicon carbide sand is uniform, so as to better ensure product quality. For example, silicon carbide fine powder is the most important abrasive in multi-wire cutting silicon wafers, and it is often used to cut harder and brittle materials.
