Coated abrasives are used in grinding wheels, abrasive sticks or stones. Grinding wheels are used in an array of applications and industries, while abrasive stones or sticks are used for honing internal or external surfaces and sharpening edges. Abrasive grains of coated abrasives are in different bond types. They are used widely to take out surface materials like ceramics, metal, plastics, glass, and paint. Most uses require a controlled flexing of the coated abrasive, base on the contour of the object to be polished and the diameter and size of the contact wheel. The polishing of a flat object with a hard, large diameter contact wheel requires little or no flex. A very irregularly contoured object polished on a small or soft contact wheel will require a very flexible coated abrasive to permit the abrasive to follow the contour. Coated abrasives are also minerals that are used in the same way as bonded abrasives. Sandpaper is a best example of coated abrasive. Coated abrasive belts, used for polishing non-ferrous metals, zinc or aluminum die castings, are often discarded before their useful life is expended because the belts become loaded with metal particles. In addition, abrasive powder functions as a buffing compound “coloring agent” by bringing out a brighter luster than is obtainable with non-abrasive filled grease sticks.
We stock manufacturers of a wide range of high quality foam coated abrasive sponges including sanding blocks, sanding pads and nail buffing blocks which are available in a range of sizes grades and grain types. Engaged in export and supply of Coated abrasive, industrial Coated abrasive, polishing Coated abrasive. Available with high alumina pedestals, grinding wheels, grinding media, thermal insulation material, ceramic fibre blankets and precast prefired block. HAZ FLAP is ideal for grinding process of every type of marble, granite, steel and stainless steel. It allows high productivity, reduces costs and high quality of the finished product. HAZ FLAP which are available as conic and flat types, have high grinding capacity and long life. Coated abrasives have grains of abrasives held collectively in a matrix of resin, rubber, glass, or other binders. All coated abrasive products are compiled of backing, grain and a binder system. The main types of backings used are cloth and paper; alternatives are vulcanized fiber, non-woven webs, stitch-bonded cloths and foils. The most important mineral types used are aluminum oxide and silicon carbide. In recent years, zirconia alumina and micro-crystalline sintered aluminum oxide made through sol-gel technology have also become more important.
