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 characteristics in areas we usually do not cover. Some of the things are named in a variety of principles when naming them. of. Among them, white aluminium oxide, 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 abrasives are the most typical raw material products produced for the abrasive industry. 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 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.
The addition amount of sintering aid and sintering temperature have obvious effects on the flexural strength of brown corundum abrasives. When sintered at 1500 ° C, when the content of MgO and TiO2 accounts for 4% of the total content of brown fused aluminum oxide, the flexural strength of the abrasive is the highest, reaching 198.38. It can be concluded that the addition of a small amount of magnesium oxide can promote sintering and inhibit grain growth. The addition of a small amount of titanium oxide can improve the strength and toughness of the brown corundum abrasive.
However, the binding agent with too large reaction capacity, because the erosion of the abrasive particles is too large, will make the edges and corners of the abrasive particles round and sharp, which has little effect on the grinding with X as the main goal. However, for grinding and fine grinding with a small amount of general removal, the quality of the abrasive grains used for dressing is much greater than that during grinding, which has a greater impact. Therefore, for abrasives with sufficient strength, especially fine-grained abrasives, it is not necessary to use a highly reactive binding agent, and it is not even appropriate to use water glass as a wetting agent.
In building materials, the ratio of mass to volume of a material is called density. Under different structural states, it can be divided into true density, apparent density, and bulk density, and apparent density is divided into bulk density and apparent density according to its open holes. Generally speaking, the black corundum density we call is the bulk density, which is also called the specific gravity. Bulk density is the mass per unit volume of dust or powder that is freely filled in a container. Bulk density is divided into loose bulk density and tapped bulk density.
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.
