What is garnet
Garnet is a kind of gem, with specific gravity of 3.8~4.0, Mohs hardness of 7.5~8.0, acid and alkali resistance, crystal shape of 32 faceted, rich and sharp corners and edges. Garnet is a high-grade abrasive.
Main uses of garnet
Garnet began to be used in industry in 1878 as abrasive for sandpaper with a small amount; From 1944 to 1988, garnet was used for polishing and grinding optical lenses, jewelry, picture tubes, etc; After 1988, high-pressure water jet cutting machine came out and was rapidly popularized. Garnet is the only available cutting abrasive, and the successful application of garnet in sandblasting and sewage treatment showed explosive growth.
Garnet usage 1:
Surface sandblasting pretreatment before spraying/electroplating In order to prevent the artifacts from corrosion for a long time, sandblasting pretreatment should be carried out on the surfaces of artifacts before spraying/electroplating to extend the service life of coatings/coatings, that is, to extend the service life of artifacts. Characteristics of garnet sandblasting ◆ The highest surface sandblasting quality can be achieved by using garnet sandblasting, and the service life of the coating/coating is greatly increased. ◆ High efficiency and low cost of garnet sandblasting ◆ The garnet sandblasting abrasive is safe, non-toxic and harmless. It is harmless to the environment and workers' health during sandblasting. It is a healthy and environment-friendly sandblasting abrasive. The quartz sand abrasives commonly used now will cause serious silicosis when sandblasting, and the copper sand sandblasting abrasives containing heavy metals will cause cancer. ◆ There is almost no fugitive dust during garnet blasting, and the working environment is good. To sum up, garnet is a new and efficient sandblasting abrasive, which is superior to traditional abrasive in terms of sandblasting quality, health and environmental protection, sandblasting efficiency, use cost and sandblasting working environment. It is an upgrade product of traditional abrasive.
Garnet application path 2:
High pressure water jet cutting abrasives High pressure water jet cutting machine tool is a multi-purpose cutting equipment with perfect performance. Its biggest feature is the processing of high-energy jet beam without heat source. There is no thermal process in the cutting, so it can cut all metal and non-metallic materials. Besides, the garnet cutting precision is high, and the cutting surface does not need to be polished. The traditional metal cutting methods include flame, plasma, laser cutting, etc., which melt the metal with heat. This cutting method makes the metal oxidized at high temperature, deformed and discolored, and has poor processing accuracy; The traditional cutting of non-metallic materials (such as glass, ceramic tile, etc.) usually uses a wire saw, which is slow in speed and low in accuracy. High pressure water jet cutting machine has obvious advantages in the cutting of metal and non-metallic materials because of its rapid popularization. Garnet is the only abrasive available for high-pressure water jet cutting machine.
Garnet usage 3:
Garnet, the filter material for sewage treatment, has the characteristics of high specific gravity, abrasion resistance, resistance to acid, alkali and chemical corrosion, moderate porosity, and no harm to the environment. The water filtering effect, service life and use cost of garnet are better than the high-density filter materials such as magnetite and ilmenite currently used, and it is rapidly popularized in the sewage treatment industry.
