Application of abrasives in coatings
Usually abrasives include artificial abrasives and natural abrasives.
Artificial abrasives include white fused alumina,brown fused alumina,pink fused alumina,black silicon carbide,green silicon carbide and so on,but natural abrasive usually means garnet sand.
Recently abrasives are used in making coatings more and more,mainly because abrasives has the applications in coating:
Improve coating quality: The use of abrasives can significantly improve the quality of paint. For example, white corundum 200 mesh and 325 mesh are used in the production of casting coatings, which improves the quality of castings; white corundum macrogrit and micropowder are used in the production of floor coatings and powder coatings, improving the quality and durability of coatings, green carborundum is widely used in the production of non-stick coatings, photosensitive coatings, Teflon coatings, powder and other coatings to increase their wear resistance and durability; brown corundum is used in wear-resistant coatings, anti-corrosion coatings, anti-rust coatings, insulation Coatings, fire retardant coatings, decorative coatings, etc.; garnet micropowder is used in novel three-dimensional spray wall coatings, which not only adds beauty to the wall, but also has excellent acid and alkali resistance.
Enhance the durability of the coating: Because the abrasive material, whether corundum or silicon carbide, not only has high hardness, but also has good toughness, it can maintain a long service life during the grinding process, thereby extending the service life of the coating.
Broaden application fields: Abrasives have a wide range of applications. They can not only be used for casting grinding under high pressure, but also can be used for fine grinding of a variety of materials, including gears, bearings, crankshafts, rolls, etc.. This makes coatings using abrasives applicable to more processing scenarios and workpiece materials.
In summary, the application of abrasives in the field of coatings not only improves the quality and durability of coatings, but also broadens its application fields, allowing coatings to perform better in various industrial and civil scenarios.
