Phosphoric acid can remove impurities from marble surface

Natural marble texture is fine, the natural joint, stone contains a small amount of impurities, in production, processing, stacked, stains, dirt, rust and other impurities will adsorption to the marble surface porosity, crack, and makes the board face ugly, especially after polishing, panel color mixed and disorderly, not beautiful, how to solve this problem, in addition to attention in processing, the first thing to analyze the structure and composition of the marble, marble on the petrology, refers to the crystal of limestone and dolomite metamorphism, most belong to carbonate, not resistant to acid and alkali, easy to weathering, oxidation, especially white sands cream-colored color to white,Many pores, holes, it is easy to absorb dirt, plate in the processing of impurities (such as rust, dirt, stains).

Only use clean water to wash not to drop, sometimes with stone cleaner also of no help, how the economy without damaging the internal structure of stone, given the strong acid, strong alkali can damage the internal structure of stone, so after numerous experiments show that the weak acid phosphate (the most weak acid, corrosion resistance, colorless) scrub, on board face no dye I phenomenon, no corrosion to the internal structure of Dali, no damage, can completely remove all the clutter of marble surface pore (rust, dirt, and retain the impurities in production and processing, the color of the wood, abrasive, etc.), make the product color fresh after polishing.

Operation method: first use hair dryer dry board face, and then the product flat on the floor, then evenly with brush brush in the panel have impurities on phosphate, disappeared see surface impurities after 5 ~ 20 minutes, reoccupy clear water is rinsed clean, if there is a little not to remove impurities, can undertake 2 times, 3 times, until completely clean, but note that with a little lower surface glossiness (3 ~ 8 degrees) and refinishing, waste of time, materials and costs.
