There are some general mentions, it has a certain degree of oxidation resistance under natural conditions.
But the copper bars used in stone inlays do not necessarily meet the conditions of "natural conditions".
Like copper oxalate, it is green. Basic copper carbonate is blue.
Under the corrosion of the crystalline material of the stone, these colored copper compounds will naturally penetrate into the inside of the stone next to the gap, and the phenomenon of green and black will appear over time.
Moreover, copper compounds are not like ordinary organic pigment pollution, which can be decomposed and taken out of the stone, so it is also difficult to clean. In addition, the copper bar itself will be corroded and lose its luster if exposed to acidic substances for a long time.
Because many marbles inlaid with copper bars, the crystalline materials used for maintenance must contain acidic components, such as oxalic acid, fluorosilicic acid and so on. Even copper with anti-oxidation ability, under the continuous corrosion of acidic materials, under the combined action of air and water, produces divalent copper ions. The copper compounds are generally green and blue.
How to maintain?
①Grinding (Diamond Turbo Row Grinding Cup Wheel concrete Masonry grinding discs) after careful processing.
When the ground is refurbished, if the copper strip can be ground and has been ground (Aluminum Based Grinding Cup Wheel supplier). Then the fine copper particles that are ground out will stay in the area of the gap twice.
Therefore, be sure to use a high-power pumping machine along the ground copper strips to pump several times to thoroughly clean the water slurry. This will suck away the tiny copper particles that we can or can't see. It can prevent or mitigate the subsequent complex changes.
②The stone is well protected
The stone inlaid with copper bars must be well protected. Especially marble with high water absorption rate requires the highest level of protective treatment. Even using high-quality penetrating protective agent or fluorine protective agent, do multiple brushing treatments. The number of passes should be increased at the gap.
③Use sealing glaze instead of crystal for polishing
Because the crystallization technology itself is built on the basis of "acid etching".
After years of development of crystallization technology, products of various brands have emerged, using different ingredients, but the basic principles are the same. Therefore, there is no crystalline material that does not contain acidic components.
In other words, if the marble floor inlaid with copper strips is polished with crystallization technology, there will always be a hidden danger of copper compound pollution.
Therefore, this kind of ground should be polished by sealing glaze technology. Can avoid the green and black phenomenon caused by copper strips.
The principle of glaze sealing technology is to apply the silicon dioxide (SiO2) component extracted from natural quartz ore to the surface of the stone.
The crystallization technology is a chemical effect, and the glaze sealing technology is a physical application.
Therefore, it will not cause any impact on the copper itself. It will also produce complex chemical changes.
