Most people are aware of the basic factors that affect the polishing process. They are: A. Suspension by power, B. Powder crystal form, C. Powder Mohs hardness, and D. Powder particle size. How much does the particle size of polishing powder affect polishing?
The size and spread of rare earth polishing powder particles are key. They greatly affect the powder’s performance.
Polishing powder particle size application;
Rare earth polishing powder can also be divided by its additive type. Rare earth polishing powder production technology belongs to micro powder engineering technology. Rare earth polishing powder belongs to ultrafine powder. Internationally, ultrafine powder falls into 3 types. These are: nanometer (1nm ~ 100nm), submicron (100nm ~ 1μm), and micron (1μm ~ 100μm). This classification method says rare earth polishing powder comes in 3 categories. They are: nanometer, submicron, and micron. We usually use rare earth polishing powder. It is usually micron-grade and has particles from 1μm to 10μm. Polishing powder made from rare earths is generally used at the end of glass polishing. It is for fine grinding, based on its physical and chemical properties. Therefore, its particle size distribution is generally not greater than 10μm. The powder has particles larger than 10μm (including rare earth powder). It is mostly used for rough grinding in the early stages of glass processing glass.
The influence of particle size distribution on rare earth polishing powder
For some polishing powders, larger particles grind glass faster. But, they make the surface rough. In most cases, polishing powders with a particle size of about 4μm have the highest grinding speed. No, smaller particles mean less grinding and speed. This improves the flatness of the glass. Typically, polishing powders have a narrow range of particle sizes. There are few particles that are too fine or too coarse. Polishing powders lack large particles. They can polish high-quality surfaces. Powders with fewer fine particles can speed up grinding.
Application of nano-level rare earth polishing powder
Rare earth polishing powder is submicron, generally less than 1μm. It has gained attention for use in liquid crystal displays. It is also used in computer optical disks. Its output has increased each year. Nano-level rare earth polishing powder has also been launched. Modern science and technology have unclear uses. Their market share is small now. They are still in the research stage.
