Reference to 1 March 2008, Beijing began to implement local standards, "architectural engineering application of technical regulations marble" (DB11T512-2007) on the marble protection waterproofing, cleaning, degreasing, in addition to plastic, water courses clean, paint rust removal, Cement removal, the overall grinding, polishing renovation, crystallization further awareness and understanding of our future services in the service and be a bit simple understanding.
Protective cleaning marble grinding and polishing at this stage leveling gradually recognized. Professional services from selected companies to regulate the construction site to the completion and acceptance of delivery and subsequent maintenance cycle Note the use of all appropriate corporate standards. The re-formation of the new marble pavement deformation of the case is not even the best installed by craftsmen can not achieve the overall roughness after grinding. In a large mill marble cutting, transportation, field assembly when the surface wear, jumping side, off angle, pollution, damage to the marble. Now install the new marble paving marble craftsmen to fill the gap by pointing agent, easy to water seepage, color, not solid.
We will be on the marble before leveling seam to clean, straight, color sealant to fill the gap, jump off side corner repair, pothole repair sheet metal surface. After leveling the marble into the ground, repair, polishing, cleaning, protection, crystal, conservation treatment. After all granite, marble, gloss can meet the state standards for superior product factory. Protection by grinding leveling grinding polishing marble after crystallization can further improve the brightness, hardness, the overall sense, stain resistance, aesthetics, fully reflect the grandeur of the original marble and high-end.
First, choose a professional qualified construction company
Through various channels, by phone or on-site maintenance visit to choose a professional construction companies play a decisive role in the quality of the final acceptance.
Second, the marble construction site specifications
1, construction of marble protection
Paving marble construction marble protection before doing the processing, use of protective agent should meet the design requirements and the protection of the purpose of scientific choice protection products. The quality of protective agent should be consistent with "a natural decorative building marble protector" (JC/T973) standards. Certificate should be valid for the test report, using the manual. Chinese imports of products export should be manual, declaration, commodity inspection alone. The content of harmful substances protective agent selected must meet the "civil engineering indoor environmental pollution control norms" (GB of 50325) requirements.
Protection treatment of marble to do the quality required to achieve the requirements of the owner or party, no pollution. Construction Protection Process: marble laying by number - Dry marble - marble cleaning - marble cleaning - front and side protector brushing twice - twice brushing the back of the protector - standing - finishing. Brushing twice when the front and sides of the protector and the internal surface must be dry marble after brushing, protective agent can be spray, brush, brush and so on, brushing the first marble in the central four weeks and then brushing Zhong Shu parts, anyway the direction of the brush again, and then brushing the side. Protectant evenly brushing, no leakage of brush. Later residues and dust wipe the surface. Specific protective construction standards refer to "Application of architectural decoration marble Technical Specification" (DB11/T512-2007) section 100-103.
2, the overall grinding marble renovation
The basis of the overall grinding paste material should be allowed before the full strength after curing to be. Ground before the first in the overall construction of the nearby objects with a protective film for more than 80CM product protection, especially wood products, paint the walls shall not cause pollution or immersion. Special unit on the floor, such as glass, marble floor wall hanging so hard to be for protection, to ensure that construction does not weeks grinding damage and pollution than objects. Of wood or high-density seal to be done playing moldings processing (to play the glass glue) to prevent the water from the marble surface water immersion following deformation kicked moldings. Protection after finishing with a 0.4MM deal within the section cutting seam, cut out of the gap can not exceed 2MM. Complete vacuum clean slit gap.
Clean up after the protection gap is not tainted with the color resin-based sealant to fill the gap after the close of marble colors. Sealing material must reach a certain depth of the depth of sealing the surface after curing should be above the plate.
No overall grind from coarse, medium, small number (50 #, 100 #, 200 #, 400 #, 800 #, 1500 #, 3000 #, 6000 #) for grinding, grinding and then rough grinding process if found in the ground have holes, off angle, crystal shedding, when there honey-like and must be completely dry form a separate patch. The overall surface roughness after grinding is not seeing a wave, in the context of the overall smoothness of the construction is 0.5MM. Test Methods: straightness tolerance (± 0.2MM) 2M's on foot, away from the wall surface should be measured, columns or other blocking objects outside 20CM. Grossly, most of the basic sheet metal grinding marble to a new board of brightness and light transmission. After grinding the marble surface should be allowed to air dry before further processing. If cross-hard materials during the construction of applications for protection, until the completion of crystal hardening. After grinding the ground can not have traces of grinding
3, crystal hardening
Hardening in the crystal surface of the marble before the best brush with water and oil repellant function, to repair the original grinding marble worn away the protective layer. Protective agent such as dried using crystal hardening agent, crystal powder and maintenance of hard-hardened liquid crystal. Crystalline material hardened marble material according to a reasonable choice of different marble crystal hardening agent. Can not use polishing powder, polishing agent instead. The choice of crystal hardening agent, hard crystal powder, supporting the maintenance of fluid content of harmful substances, must meet the "civil engineering indoor environmental pollution control" (GB50325) requirements. Crystal marble ground Yaoqiu drying before curing shall not have cracks, water stains, water courses, or other disease, no pollution, no dust, no bonding glue, marble surface gloss of not less than 50 degrees. 175,208,300 common ground crystalline rev / min weight 40-70KG multi-functional crystal refurbished hard drive or a professional machine. Crystallization can be used like steel wool polishing pad, requiring site formation, full, and on the need to do the hard marble ground grain to grain hardening agent is ready to clean up the ground can not have a barrier property to open, install needle plate, pressure plate well in the wire cotton, start the machine can be hardened crystal. If the beginning of crystallization when the ground polished black marble in the renovated mill that did not completely dry or the ground water too much dust. If time permits, and other marble dry before making a crystal can be used if time does not permit the use of the following crystalline powder with a polishing pad crystallization treatment. Grinding shall not be less than 5 times, until the crystal hardening effect.
Crystallization of the steel wool wall into a small pan with the governor speed adjusting hand polishing machine will turn 400 below the pressure plate a good steel wool grinding head polishing machine in hand under the marble surface on the test machine in order to steel wool does not prolapse is not subject to spread, start grinding machine normal crystal hardening. Not less than three times polished until the crystal had to hardening effect. Crystallization of the granite wall above the ground with the corresponding crystal hardening agent for crystallization of granite processing. Crystallization can also be used when curing pad with crystal crystal crystalline powder. White cushion pad mold available, red mat (not fade), horse hair pad and crystal powder crystals. Hard crystal marble powder diluted with water, was better than paste. Under uniform pressure in the polishing pad, start the machine uniform grinding and polishing can be add a little water until crystals appear bright hard marble effect. Hardened crystal and glass must be cleaned with water scraper scraper. Crystalline powder with a crystalline hard granite hardening agent into a paste, even under pressure in the grinding pad, polished to a bright, crystal hardening effect can appear. After hardening the surface of crystal gloss mirror had obviously improved, no marble should be worn over the marble a new national standard. Loss of a grinding marble crystal optical phenomena should be apparent after hardening crystal hardened layer, the gloss at least 10 gloss units. Crystal should have some hardened non-slip effect. Can not leave when the grinding marble grinding traces of crystallization, the surface can not spend, there can be other colors. Attention to product protection tips Party, crystal surface should be kept clean and, after hardening can not have dust, or liquid pollutants. Prevention, human galling scratches. Ground leveling, repair, refurbishment, polishing, protection, crystallized marble surface, flat and bright as a mirror near distance, seen through the light intensity is high, from the marble surface can clearly see objects above the ground surface of the image in the marble. Improve the marble's stain, increase the hardness of marble, marble to improve brightness, enhance the texture of marble, fully embodies the high-grade marble.
Third, the post-maintenance considerations
Party after party in the use of the delivery note as little as possible with water when cleaning and maintenance, it is best to use spray oil on the dust dust led push push dust regularly maintained. Dust onto the dust and spray oil on the pull of 24 hours or completely into dust can be used to push Bristol faces. Dust plot for a long time to push long-term use the dust cloth dust mop can be washed off again. If there is dust in the ground pushing when things do not go inside that can be used alone tidal scrub cloth. Try to keep the ground clean, no sand, sand, dust, acid alkaline cleaning agent on the marble the most devastating. marble in dusty areas or high traffic wear and tear on the marble surface to increase, shortening the time of marble high brightness, the average family re-crystallization hardening period of 1-2 years, the hotel building hotel crystal hardening cycle in 15 days - half a year. Crystal hardening concrete on-site maintenance over the same period the actual subject.
