The function of the wetting agent is to wet the brown fused alumina before mixing it into the molding material, and then mix the material to maintain the wet strength of the green body. Common wetting agents are ethanol, water, motor oil, kerosene, etc. The general dosage is 0.1% ~ 0.8%, and the strength of the abrasive tool can be increased by 10% ~ 30%, the combined dosage of SiC abrasives is more than that of green silicon carbide.


Plasticizer is used to reduce the glass transition temperature of resin, increase fluidity, and improve the toughness of brown aluminum oxide tools. Dibutyl phthalate, polyamide, liquid glue, etc. are commonly used. The coupling agent is to promote the formation of a chemical bond between the bonding agent and the adhered aluminum oxide grit, and improve the bonding strength. Commonly used coupling agents are Volan, A-151, KH-550, KH-590, B201, B202.


Ordinary resin abrasives refer to resin abrasives of corundum and silicon carbide abrasive. The formula design of the resin binder is to determine the proportional relationship among the set abrasives, abrasives, binders, fillers and auxiliary materials. The mass of abrasive is 100 parts, and the other materials are expressed as a percentage of the synthetic corundum and the total mass of the raw materials of each component of the abrasive tool is 100 parts.


The basic elements of ordinary resin abrasives are the type and size of brown aluminium oxide, abrasive hardness, combined dosage, abrasive structure, forming density or pressure. Under the same conditions, the combined dosage of mixed particle size is less than that of single particle size. Especially for high-strength black silicon carbide, increasing the forming density is more effective than adjusting the combined dose, and the percentage of each raw material is the total mass.


The relationship between the type of white alumina and the combined dosage: the relationship between the particle size of the abrasive and the binding agent; the relationship between the forming density and the hardness of the abrasive article; the relationship between the combined dosage and the hardness of the emery abrasive article. Under the same conditions of particle size and forming density, to make abrasives of the same strength level.


When the strength (or hardness), type of black corundum, and forming density (or pressure) of the abrasive are the same, the combined dosage increases with the increase of the abrasive particle size number, that is, the finer the abrasive, the more binder is required. In the case of the same type of abrasive, particle size and forming density, increasing the combined dose can improve the strength and hardness of the garnet abrasive tool.


Grit size determines the roughness and grinding efficiency of the pink corundum surface being machined. The basic rule for the formulation of resin abrasive tools is to control well: in the case of the same type of abrasive, particle size and combined dosage, as the forming density increases, the hardness and strength of the abrasive tools also increase. Adjusting the forming density is the main method for adjusting the hardness and strength of the garnet suppliers abrasive tool.
