Stone polishing abrasives what role

Stone with its elegant posture , loved by the people , with economic development , more and more extensive use of stone , especially a variety of public places, but the use of stone , as time changes, there  sanding paper will be pollution and other issues of aging , which can be By way of preliminary cleaning solution , but sometimes must be refurbished by grinding way to achieve the following through abrasive materials , abrasive materials introduced , so that we have a preliminary understanding of this .
Abrasive polishing materials are used , are generally classified ordinary abrasives, superhard abrasive types ; ordinary abrasive including corundum ( corundum, corundum , etc. ) , and  concrete ring saw its main chemical composition Al2O3 ( aluminum oxide ) , silicon carbide ( black silicon carbide, green silicon carbide ) , and its main chemical components of SiC (silicon carbide ) .
Diamond grinding tools are metal, resin , ceramic, etc. , which are classified according to type of binding agent , metal abrasive materials include iron, copper , cobalt-based these categories , will determine the different types of materials, processing costs, which is characterized by long life, but the cost will be higher . resinous abrasive materials, due to the production costs are relatively low, the application should be  cutting discs relatively more, it is now also used for rough grinding to polishing, polishing fine-grained aspects of its greatest advantage ; ceramic diamond in recent years, the fastest growing abrasive tool , its processing performance , the length of metal processing , to avoid resin processing short, is technically a very good advantage, but because of cost reasons , have not seen the stone used in the refurbishment .
