As the name implies, resinoid grinding wheels are grinding wheels made of resin. Their advantages are high strength, certain elasticity, good self-sharpening, simple production, short process cycle, and they are widely used in rough grinding, rough grinding, cutting and free grinding. The quality stability of resinoid grinding wheels is different, and its stability is related to the raw materials:
1. Liquid phenolic resin, the solid content, viscosity, gel time and water solubility of liquid phenolic resin and other indicators and fluctuation ranges are affected to varying degrees. Therefore, grinding wheel manufacturers must formulate their own liquid resin technical indicators and ranges based on their own product performance requirements, combined with their own mixing, molding and hardening process characteristics. In addition. Liquid resin must be stored correctly, because liquid phenolic resin is very unstable, and its technical indicators will change even at room temperature. Grinding wheel manufacturers must store liquid phenolic resin at low temperature to ensure the technical indicators and range of liquid phenolic resin. In addition, liquid phenolic resin must be stored correctly, because liquid phenolic resin is very unstable, and its technical indicators will change even at room temperature. Grinding wheel manufacturers must store liquid phenolic resin at low temperature to ensure the stability of liquid phenolic resin, and then ensure the stability of resinoid grinding wheel mixture and the stability of resinoid grinding wheel quality.
2. Powdered phenolic resin. For powdered phenolic resin, the fluctuations of flow length (fluidity), particle size, (particle size, fineness), hexamethylenetetramine (six times) content and generation time will affect the quality stability of resinoid grinding wheel.
