Brown aluminum oxide micropowder P series
Brown aluminum oxide is made of high-quality bauxite as the main raw material. It is made into products of various particle sizes by purification, impurity removal, crystallization, sorting, crushing, magnetic separation, screening and other processing methods in an arc smelting furnace at a high temperature of more than 2200℃. The P series micropowder is made by acid washing and water washing, overflow classification under the P series, drying and screening.
Brown aluminum oxide micropowder P series is a special grinding material for coated abrasives. Its size standard, application scenarios and production process have the following characteristics:
1. Definition and particle size standard
Standard system
The P series belongs to one of the size standard of brown aluminum oxide micropowder, which is parallel to the W series, Fepa series and JIS series, but focuses on different application scenarios.

2. Application scenario
Coated abrasive manufacturing
The P series brown aluminum oxide micropowder is the core raw material of coated abrasives such as sandpaper, emery cloth and abrasive belt, and is suitable for high-precision surface treatment
High-precision grinding and polishing
Used in high-precision workpiece grinding processes in semiconductor, precision casting, refractory materials and other industries, such as semiconductor wafer polishing.
Special industrial fields
It is also widely used in sandblasting (such as acrylic surface treatment), superfine grinding paste preparation and other fields.
3. Purchase suggestions
It is necessary to select the size in combination with the process requirements.
For example, P500 and P600 brown aluminum oxide are often used in the semiconductor industry, and P320 and P240 are mostly used for general-purpose coated abrasives. In addition, P series brown aluminum oxide micropowder can replace the similar size under W series, JIS series or Fepa series, and even have better effects, such as brown aluminum oxide micropowder P280 P400 for sandblasting mobile phone carbon plates.
In summary, brown aluminum oxide micronpowder P series is an industrial raw material that is both universal and professional. Its selection needs to comprehensively consider the size, application scenario and production process differences.
