With the development of the cutting sheet industry, cutting sheets are now more and more widely used in our industrial production. Many users also choose to use the green cutting disc. Although everyone has a certain understanding of them, for cutting The production process of the film is not known to many people. Today, the Aurora Abrasives will give you an explanation of the production process of green cutting disc.
Cold pressing process: The bonding agent used in the cold pressing process is a wetting agent and a powdery resin. The liquid phenolic resin, furfural, decyl alcohol, cresol and the like are usually used as a wetting agent, and the most used liquid phenolic resin. The factors determining the proportion of liquid resin and powdered resin are abrasive particle size distribution, filler type, filler amount, the viscosity of the liquid resin, properties of the powdered resin, and the like. If the viscosity of the liquid resin is larger, more liquid resin is required to completely cover the surface of the abrasive; the smaller the particle size of the abrasive and the filler, the larger the specific surface area, and the more the liquid is used; the molecular weight of the powdered resin is higher. The lower the high and free phenol, the worse the adhesion to the liquid resin and the greater the amount of liquid required. In all of the above cases, it is necessary to increase the liquid to powder ratio. Generally, a liquid resin is used as a wetting agent, and the ratio of liquid to powder is 1:2 - 1:4, and a mixture of furfural or decyl alcohol and eucalyptus oil is used as a wetting agent, and the ratio of liquid to liquid is 1:6 - 1:8. The mixer is process-proven to achieve the desired mixing and does not damage the abrasive. The mixing time after adding the fine powder is generally 2-4 minutes. If the mixing is too short, the mixing is not uniform, the resin film is too long to fall off, and the temperature of the material is raised, and the resin is pre-cured.
