Analysis of three major aspects of the new standard of renovation technology in the stone industry

First, the stone renovation of the finished product protection: 1, before construction must use plastic film glued to the wall, door leaf, door frame, furniture, floor and door and other parts, the height of at least 30cmm or more, after the completion of construction, remove the protection, inspection, cleaning tape and possible Defacement of the stain. 2. The construction unit must be equipped with a vacuum cleaner with water absorption function. The water on the stone working surface should be cleaned up in time when cleaning and polishing. 3, 10cm from the ground to use hard material protection to avoid bumps. Second, the stone renovation process requirements: 1, waterproof treatment, after renovation, no water back phenomenon. Caulking treatment: 3mm seam; tailoring with an angle grinder. 2. Use the knives to remove the concrete slurry at the gap of the stone first, and then thoroughly remove the dust with a brush, a vacuum cleaner, etc. 3, using imported stone professional caulking agent to fill the gaps and holes in the stone. 4. For the renovation of granite, bridge mills and professional grinding discs must be used. Resin grinding discs should not be used. Rough grinding: Do not reduce the number of grinding passes and change the number of grinding pieces. The 60-mesh grinding piece polishes the cut, height difference, scratch and deformation of the stone floor. The color of the glue is basically the same and must be full. Fine grinding: Do not reduce the number of grinding passes and change the number of grinding pieces. 5, 120 mesh, 220 mesh grinding to eliminate the traces left by the rough grinding. 6, 400 mesh, 800 mesh continue to finely polish the stone surface. Polishing: Do not reduce the number of passes and change the number of pieces. 1200 mesh, 2000 mesh, 6000 mesh polishing pad polishing 7. Repair: After grinding and drying, perform secondary repair. 8, the use of stone special repair, caulking rubber for the repair of some cracks after grinding. The part of the caulking rubber that is not full or peeled off is repaired twice, so that the seam and the corner of the chipping are flat and full. 9. After the stone surface is dry, do the crystallization and hardening treatment until the surface effect required by the sample is reached. The refractory travertine stone surface has a mirror gloss of 60 degrees or more, and there must be no difference in height between the stones. The granite stone surface reaches 80 degrees or more, and there is no leakage phenomenon. Third, the stone renovation to the sample of the liquid medicine, caulking rubber to seal the sample.
