In life, copper strip is more common, wall, ground, machinery and so on, can find the figure of copper strip, which marble inlaid copper strip is more common, we all know that copper strip for a long time will produce verdigris, will be very ugly, how to avoid this?
① stone to do a good job of protection
The stone material of enclose copper strip, must do a good job of protection. Especially the marble with higher bibulous rate, it is the need for advanced level protection treatment. That is, the use of high quality penetration type protective agent or fluorine protective agent, do more than brush treatment. In the gap should also increase the number of times.
② Careful treatment after grinding
When the floor is being refurbished, if the copper strips can be ground and have been ground. Then the fine copper particles, which are ground out, will be stuck in the area where the cracks are twice.
Therefore, must use high-power pumping machine along the polished copper bar, pump a few times, the water slurry thoroughly clean. This sucks away the tiny particles of copper that we can see or not see. Can prevent or mitigate complex changes that follow.
③ with sealing glaze instead of crystallization for polishing
Because the crystallization technology itself is built on the basis of "acid etching". Crystallization technology has developed over the years, and various brands of products have emerged using different ingredients, but the basic principles are the same. Therefore, there is no crystalline material that does not contain acid. That is to say, the marble ground that inlaid copper bar, polish with crystallization technology, always have the hidden trouble that produces copper compound pollution.
Therefore, this kind of ground, to use sealing glaze technology to polish. The principle of sealing glaze technology is to extract silica (SiO2) from natural quartz ore, applied to the surface of the stone. Crystallization technology is chemical action, sealing glaze technology is physical application action. So it doesn't have any effect on the copper itself. Complex chemical changes can occur. Can avoid the occurrence of copper strip caused by the green, black phenomenon.
