Marble, commonly known as marble in the world, is widely used for building interior walls because of its natural and primitive texture and bright color. Marble is relatively loose and soft, and its water absorption is relatively high. There are many joint lines, so in process of processing, transportation, installation and use, various pollution, warping, deformation, loss of light and other phenomena are easy to occur, affecting the decorative effect. Therefore, the care of marble is also a required course in the nursing industry. To compare and analyze the status of marble veneer, nursing methods can be divided into:
1. Refurbishment grinding treatment. 2. Local drop treatment. 3. Cleaning and protective treatment. 4. Crystal polishing treatment. 5. Seamless filling treatment, etc.
Pembinaan proses daripada marmar pengisaran dan kristal menggilap:
Pertama, waterproof measures shall be taken before the renovation and polishing to reduce the water absorption of the stone as much as possible. Waterproof measures shall be taken after 300 #. At that time, the waterproof effect will be reduced or disappeared due to grinding. If conditions permit, it is better to take waterproof measures after 800 #.
In case of loose stones, such as white sand and beige, sandstone, tropical rainforest, wood grain stone, etc., high content sealing agent (such as super hard inorganic coating, organic silicone resin sealant with a content of more than 40%) shall be used for pre-treatment to make the stones harden while filling the loose.
1. Rough grinding: use 50 #, 150 #, 300 #, 500 # diamond resin hard grinding blocks (do not use soft water grinding discs for rough grinding, which is prone to waves and affects the flatness). The water supply for rough grinding is slightly larger, but remember not to use too much water. After each grinding disc is polished, thoroughly absorb water. Check the deep scratches left by the shear abrasives are polished off with 50 # grinding discs, and so on. The machine takes 45% of the overall grinding time for rough grinding, It is the key link to ensure the quality acceptance of project completion.
2. Fine grinding: 800 #, 1000 # and 2000 # diamond resin soft water grinding discs are used. Fine grinding takes up 35% of the overall grinding time. After fine grinding to 800 #, there is initial light, and after fine grinding to 2000 #, the glossiness can reach 50 degrees.
3. Fine grinding: 3000 # diamond resin soft water grinding disc is used to spray A2 grinding, conduct ion exchange, and fine grinding takes up 20% of the overall grinding time. After fine grinding, the glossiness is greatly improved, and the surface density of marble is improved, laying a solid foundation for the polishing agent (NO{2+Q5 mirror repair agent), and enhancing the adhesion daripada menggilap bahan.
4. Polishing: Use a crystal surface machine with a power of more than 2HP, rotating speed of 175-210 rpm, weight of 45-70 kg, animal hair pad with 70% animal hair content, 3M pad, nano pad, marble mirror face make-up cream NO2, 2X mirror face locking knife into milk Q5 for polishing and grinding. After polishing, the marble surface gloss can be at least 90-100 degrees.
5. In case that it is difficult to make transparent stones, such as jazz white and resin artificial stones, if the above methods are still not bright enough, then spray A2 once more and grind it to dryness with 3000 #, and then repeatedly polish and grind it with nano pad, marble mirror face make cream NO2, 2X mirror face locking knife into milk Q5, so that the nano inorganic polymer copolymer can form a crystal layer, which is glassy and bright. It has high hardness, abrasion resistance, transparency, water resistance, dirt resistance, skid resistance, etc.
