With the continuous deepening of the news media in various fields in various industries, we have gradually learned a lot about the latest features of some of the features in areas that we usually do not cover. The principles of naming are diverse of. Among them, brown corundum, which is commonly used in the industrial field, is also named because of its function and properties; another name for its corundum is also because of its main use.
Emery manufacturers have high requirements for quality inspection and must meet qualified production specifications in order to better launch them on the market. Emery manufacturers also have strict requirements for the production of other raw materials. Among them, resin sand is a more prominent one and silicon carbide abrasive has played a significant role in applicable industries. The application characteristics of glass sand are relatively obvious, and the outer packaging is used for decoration, and has gained a lot of recognition.
Pure silicon carbide is generally non-conductive, but if the proportion of carbon and silicon is appropriate, it can become a semiconductor. This kind of semiconductor is different from some other semiconductors such as silicon, germanium, etc. It is a special semiconductor material, even if the temperature is as high as 1000 ° C, it still has semiconductor properties. The reaction ability mainly refers to the ability of the binder to dissolve the surface layer A12O3 in the corundum abrasive. Emery abrasives are the most typical raw material products produced for the abrasive industry.
So how to calculate the bulk density of aluminum oxide grit? What is the weight per cubic meter? Let’s continue: The common method for calculating bulk density is presumably everyone will be the mass per unit volume of corundum / unit volume of corundum, take each cubic meter The density of silicon carbide is the mass of 1 cubic meter of silicon carbide / 1 cubic meter, and the volume density of general silicon carbide is 3.20 ~ 3.25g / cm3.
White corundum abrasive has a well-known characteristic, that is, hydrophilicity. How do you understand this? The white corundum manufacturer will explain the hydrophilicity of white abrasive. The so-called hydrophilicity is the ability to attract water molecules. The molecules with polar groups on the surface of many materials have a large affinity for water and are easily wetted by water. Generally, abrasives have such properties, and the abrasiveness of white corundum abrasives is more ideal, which is mainly related to the properties of their materials.
As for the molding material of the abrasive tool, since it is composed of a variety of green silicon carbide powder materials with a monthly density and a wetting agent is added, the bulk density and the formula of the molding material, the types and number of the lubricant It has a relationship, more specifically, it has a relationship with the type and size of the abrasive, the type and density of the wetting agent, and the address of the wetting agent (that is, the dryness and wetness of the molding material). The former conditions generally change less.
