磨抛可以使表面失光、表层粉化剥落、表面溶蚀的石材光面恢复原有的天然外观。一些新的磨具、磨料和化学助剂的结合可以使翻新后的石面达到9O度以上的镜面光泽度。清洗和翻新处理以后石材微孔隙应尽早作防护处理，由于石材微孔隙在清洗和翻新后被打开，增大了比表面积，加大了对灰尘和污液的吸附和扩散的能力.若不及时作防护处理很容易再次被污染。
Grinding and polishing can restore the original natural appearance of smooth surface of stone materials, such as surface losing gloss, surface powdering and peeling, and surface dissolution. The combination of some new abrasives, abrasives and chemical additives can make the retrofitted stone surface reach a mirror gloss of more than 9O degrees. After cleaning and renovation, the micro-pore of stone should be protected as soon as possible. Because the micro-pore of stone is opened after cleaning and renovation, the specific surface area is increased, and the ability of adsorbing and diffusing dust and dirt is increased. If not treated in time, it is easy to be polluted again.
