The role of the binder during the press molding process is mainly to increase the strength of the compact or prevent powder segregation and is a substance that is added to the powder and can be removed before sintering or during the sintering process. The binder is the guarantee of the bonding strength between the abrasive and the matrix. It can reduce water, plasticize, flocculate, etc., while ensuring that the structure of the adherend will not change significantly and giving the bonded surface enough strength. strength. During the press molding process, the type and amount of binder need to be rigorously screened and tested to ensure that the quality and performance of the pressed blank meet expectations.
