(1) Resina fenólica líquida. El rango de fluctuación de indicadores como el contenido sólido, la viscosidad, el tiempo de gel y la solubilidad en agua de la resina fenólica líquida tiene diferentes grados de influencia, por lo que la muela abrasivaEl fabricante debe desarrollar los indicadores técnicos y la gama de resina líquida adecuada para él de acuerdo con sus propios requisitos de rendimiento del producto, combinados con sus propias características del proceso de mezclado, moldeado y endurecimiento. Además, las resinas fenólicas líquidas deben almacenarse correctamente, ya que las resinas fenólicas líquidas son inherentemente muy inestables y sus especificaciones técnicas pueden cambiar incluso en condiciones de temperatura ambiente. El fabricante de la rueda debe almacenar la resina fenólica líquida en condiciones de baja temperatura para garantizar la estabilidad de la resina fenólica líquida, lo que a su vez garantiza la estabilidad de la mezcla de la rueda de resina y la estabilidad de la calidad de la rueda de resina .

(2) Powdered phenolic resins. For powdered phenolic resins, fluctuations in flow length (fluidity), particle size, urotropine content and gelling time can affect the quality stability of the resin grinding wheel. In this regard, flow length is the first consideration that should be made. These indicators illustrate the changing behavior of the resin under certain experimental conditions. They are only resin performance indications, and the exact magnitude of the effect on the performance of the grinding wheel product can only depend on the actual application of each resin wheel plant. The flow of the powder resin is the most important performance indicator affecting the structure of the bond, the particle size affects the amount of wetting agent, and the content of volatile components (free phenol, moisture) is also important. In the actual grinding wheel production process, it is necessary to ensure the stability of the performance of each batch of powder resin, so as to ensure the quality of the grinding tool.

(3) Stability of the technical index of the mesh. The most important role of mesh flakes initially applied in resin grinding wheels is to improve the strength of grinding wheels. With the continuous improvement of the performance of resin grinding wheels, the role of mesh in resin grinding wheels becomes very important. It is mainly manifested in the fluctuation of grinding wheel strength, the deformation of slices, and the delamination of grinding discs. Theoretically speaking, under the condition that the grinding wheel production process is stable and allowed, the higher the gum content of the mesh, the higher the strength of the grinding wheel, the better the bonding performance, and the more stable the cutting and grinding at the same time.
