Grinding white corundum sand is a commonly used abrasive material for metal surface treatment, 光学ガラス, セラミックス, 等. for fine processing and polishing. It has the advantages of high hardness and good heat resistance. 記事上で, we will introduce the grinding process, application areas and characteristics of abrasive white corundum sand.

I. Grinding process of white corundum sand

The grinding process of white corundum sand includes the following steps:

Rough grinding: use the coarser grain size of white corundum sand for rough grinding, go to the hard surface of the material, laying the foundation for the subsequent fine grinding.

Fine grinding: Use the finer white corundum grit for fine grinding to make the surface of the material smoother and flatter.

Polishing: Use fine-grained white corundum sand to polish the surface of the material to achieve a mirror effect.

Characteristics of white corundum sand

White corundum sand is a kind of ore treated by screening, crushing, magnetic separation, screening and other processes, with the following characteristics:

Heat-resistant temperature: white corundum sand has excellent heat-resistant temperature performance, and can maintain stable grinding performance in high temperature environment.

High purity: White corundum sand has a pure chemical composition and low iron content, making it suitable for grinding applications that are sensitive to iron contamination.

Chemical Stability: White corundum sand is highly chemically stable, not easy to react with acids and alkalis, suitable for various acid and alkali grinding applications.

高硬度: White corundum sand has high hardness and can withstand high loads of grinding pressure, which can remove hard spots on the surface of the material.

During the grinding process, the appropriate grain size and grinding process should be selected according to different applications and material types to achieve the grinding effect. Meanwhile, in order to ensure the grinding quality, operators need to be professionally trained and use qualified grinding equipment and process parameters.
