Abrasive paper is used for many products nowadays. It is a kind of product for surface grinding and is used in many fields. So what are the types and production process of abrasive paper? Here are a detailed introduction.
1. Sponge abrasive paper: It is suitable for grinding smooth parts of all kinds of materials.
2. Dry-grinding abrasive paper: It is made by bonding silicon carbide abrasive on latex with synthetic resin as binder and is coated with anti-static coating. It is a high-grade product with the advantages of anti-blocking, anti-static, good flexibility and high wear resistance.
3. Water-grinding sandpaper: It is suitable for grinding some things with fine texture and for post-processing because of its fine texture.
1. The selection of abrasive
Select different abrasives according to different requirements. Silicon carbide or alumina is preferred. After the selection of the abrasive, the abrasive materials need to be divided as fine as possible. There are 60 #, 80 #, 100 # and other types of sand. If 400# sand is mixed with 600# sand, the quality will be very poor. So please pay special attention.
2. The Selection of paper
The raw materials of paper are grass, miscellaneous trees, good wood and bamboo. When the wholesale price of the abrasive paper is less than 0.6 yuan, it is made of miscellaneous trees. The price of abrasive paper made of good wood is about 1 yuan. The wholesale strength of abrasive paper is very high.
Glue formula determines the firmness. More EVA means greater fastness. If you want to know more about abrasive paper, please consult and follow ZIBO RIKEN MT COATED ABRASIVES CO., LTD.
