The advantages of garnet abrasives in the sandblasting industry
At present, the main garnets traded in international trade are iron-aluminum garnet and calcium-iron garnet. These two kinds of garnets are hard and heavy, and have wide industrial uses.
The use of garnet: The use of garnet began in the Bronze Age, mainly as a gemstone and abrasive, so according to the use of garnet, it is divided into gem-grade garnet and industrial-grade garnet.
Garnet has strong chemical inertness, high melting point, good toughness, insoluble in water, only 1% solubility in acid, basically free of silicon, and has high resistance to physical impact; as well as high hardness, edge sharpness, grinding Cutting force and specific gravity, combined with its recyclability, make it an ideal multi-purpose material for many sectors of industry; from being a leachate medium to water jet cutting, sandblast grinding and more. Use garnet; it has been used in many important industrial sectors, such as optical industry, electronics industry, machinery industry, instrumentation, printing industry, building materials, and mining and other sectors;
As a grinding grade garnet, it can be subdivided into two categories: sandblasting grade and water blasting grade; crushing the mined or collected garnet into small particles; more than 60 mesh is usually used for sand blasting; 20 mesh to 60 mesh garnet is used for For water jet cutting; others smaller than 20 mesh, for polishing glass and lapping; in general, larger particles are used for rapid machining operations, while smaller particles are used for fine trimming;
Sandblasting and grinding media: There are three main purposes: First, sandblasting grade garnet can be used for sandblasting, rust removal, sandblasting and decontamination, grinding steel and other materials, for metal surface preparation in shipbuilding and large-scale complete equipment manufacturing, ship maintenance, etc. ;
