Mild renovation of marble: if the stone surface is slightly scratched, a mild renovation process can be used for renovation. If there is old wax on the ground, wax it first, and then polish it with 800 # diamond sanding pads and clean water for ten minutes. Note: add water during the polishing process to keep the ground wet, and use the water suction machine to absorb the sewage to prevent the sewage from polluting the ground for the second time. Then replace 1500 ＃ and 3000 ＃ polishing discs and diamond grinding discs, and polish them one by one with the above methods. After all the renovation procedures are completed, clean and absorb the water on the stone surface with clean water, and the light renovation of marble is completed. Moderate renovation of marble: when the stone surface loses luster and can not reflect the object completely without too deep scratches, the moderate renovation process can be used for renovation. Use 200 ＃, 400 ＃, 800 ＃, 1500 ＃, 3000 ＃ polishing discs and wet diamond polishing pads to grind one by one, and the grinding methods and precautions are consistent with the above.
Deep renovation of marble: when there are holes, weathering, serious corrosion, complete loss of luster and deep scratches on the stone surface, the deep renovation process can be used for renovation. Before renovation, the holes shall be repaired as follows: first clean the dirt in the holes, and then dry the stone in the air. According to the color and reflective characteristics of the original stone, the imported epoxy resin glue or unsaturated resin glue shall be used. After color mixing, the holes shall be repaired. The weighing machine, renovation plate and 50 ＃, 150 ＃, 200 ＃, 400 ＃, 800 ＃, 1500 ＃, 3000 ＃ diamond polishing pads shall be used for grinding one by one. The polishing method and precautions shall be consistent with those of light refurbishment.
Precautions:
1. When using the portable water mill polishing machine, the motor speed should not exceed 4500 rpm; The maximum pressure is within 3kgs/cm2.
2. It is better to select soft (water) grinding discs with the same color as the stone to prevent staining.
3. Grinding sequence: from coarse to fine, and then polishing. The whole process needs adequate water cooling, but the water volume should not be too much in the polishing stage. Generally, there are many diamond water grinding discs used for stone grinding. The diamond water grinding discs are made of diamond micro powder and resin bond materials with exquisite technology and advanced production process. They are mainly used for grinding and polishing of natural or artificial stones of various shapes, as well as for cleaning, finishing and updating of decorative stones. Tianbang’s water grinding discs can be flexibly matched with various hand grinders, floor refurbishers, ceramic polishers, angle grinders, horizon grinders, etc. according to customers’ needs and habits. The grinding sequence is from coarse to fine, and then polishing to obtain the ideal surface effect.
characteristic:
1. The grinding plate has uniform blade, sharp and durable, stable quality, long service life, high working efficiency, good surface finish, environmental protection, non-toxic and non fading.
2. It has a complete and standardized grain size color system and good flexibility, and is skilled in processing granite, marble, artificial stone and other lines, chamfers, curved plates and special-shaped stones? There are avariety of shapes and specifications available, and various particle sizes are easy to identify.
3. The diamond dry grinding disc can finish polishing and grinding of stone, glass, ceramics and other materials without water cooling
