2. Characteristics
①The texture of garnet sand is hard, with a Mohs hardness of more than 7.1, which is higher than that of commonly used quartz sand, sea sand, river sand and other sandblasting materials, and has a long service life.
②Because garnet is a crystal of an isometric system and has no cleavage, which it is easy to form approximate cube particles with edges and angles after making it into sandblasting, and the effect of sandblasting and rust removal is better. It can not only completely remove the rust, oxide skin, coating and its pollutants on the metal surface, but also because of its high hardness, it can produce an ideal angular rough surface on the cleaned metal surface, increasing the surface area of the metal, improving the adhesion of the interface, and making the binding force of corrosion-resistant protective coating and the metal surface significant. So it can enhance to improve the bonding performance of the coating and the metal surface.
③The density of garnet sand is larger, usually about 4g/cm³, strong impact force, which can better clean the metal surface.
④High strength. Treating the metal surface,garnet sand is not easy to break. Even after it is broken, it will produce new angular, almost cubic particles, so that it can be used repeatedly, usually up to 20 times. It is 20 times of siliceous sand (sea sand or river sand) and more than 2 times of quartz sand (artificial), and its relative cost is low once used.
3. Application
Water treatment: Garnet sand packed in filters can be used to remove suspended particles and impurities from water.
Anti-slip material: Garnet sand mixed with resin and other materials can be made into anti-slip material for floor finishes or walkway surfaces.
Chemical catalyst: It can be used as an auxiliary for chemical catalysts, such as in the synthesis of methanol catalyst.
Decoration material: Garnet sand is processed into different shapes and sizes of stone, which can be used for building decoration, indoor flooring, etc.
