1. Resin grinding wheel powder phenolic resin. For powder phenolic resin, fluctuations in flow length, particle size, urotropine content and gel time will all affect the stability of the quality of the grinding wheel. The process of powder resin affects the bonding agent The most important performance index of the structure, the particle size affects the amount of wetting agent, and the volatile content is also very important. In the actual grinding wheel manufacturing process, the stability of the performance of each batch of powder resin must be ensured to ensure the quality of the grinding wheel.
2. Liquid phenolic resin for resin grinding wheels. The solid content, viscosity, gel time and water solubility of liquid phenolic resins have varying degrees of influence. Therefore, grinding wheel manufacturers must combine their own product performance requirements according to their own product performance requirements. Blending, molding and hardening process characteristics, and work out the technical indicators and scope of liquid resin suitable for oneself.
3. The stability of the technical indicators of the resin grinding wheel mesh. The mesh was initially used in the resin grinding wheel, and the most important role was to improve the strength of the grinding wheel. With the continuous improvement of the performance of the resin grinding wheel, the role of the mesh in the resin grinding wheel is very important.
