Conservation of natural marble has a new way!

With the rapid development of stone industry, stone conservation, more and more attention. More and more people into stone conservation methods and products in development. Currently, the conservation of natural marble, has a new way! Phosphate surface of marble slabs can also be cleared of impurities. This approach not only low-cost and easy to learn.
Finer texture of natural marble, natural joints clear stone contains small amounts of impurities. In the production, processing, stacking, the stains, dirt, rust and other impurities will be adsorbed to the surface of the marble plate pores, cracks, combined make the board ugly. Especially the polished plate surface color messy, unsightly.
To solve this problem, in addition to the processing of attention, the first to analyze the structure and composition of the marble. Marble on the petrology, metamorphism is made of limestone and dolomite crystals, most of them are carbonate, not acid, is easier to weathering, oxidation, especially white sand beige color is milky white, pores, holes and more it is easy to absorb dirt, board retained in the processing of impurities (such as rust, dirty things, stains). Only clean water will wash off, sometimes with a stone cleaner does not help, how the economy without damaging the stone's internal structure, taking into account the strong acid, strong base may damage the internal structure of stone, so after numerous experiments proved that the use of weak acid (the weakest acidic, corrosive small, colorless), wash the plate surface without dye my phenomenon, there is no corrosion of the internal structure of marble, no damage to the marble surface of the pores completely remove all debris (rust point, dirt, impurities remaining in production and processing, wood, abrasive colors, etc.), making the polished bright as ever after the color of the product.
How: First, dry the board with a hair dryer, and then the product flat on the floor and then, even with a brush in the brush at the plate surface impurities on phosphoric acid, see 5 to 20 minutes after the board of the impurities disappear, and then water rinse, if the small amount of impurities are not removed, can the 2nd, 3rd, until it is completely clean, but be careful, the board are slightly lower gloss (3-8 degrees), again, polishing, waste of time, materials and costs.
