It is not difficult to find that the performance of aluminum coil is very stable, not easy to be corroded, and light per unit volume. This is also the reason why many architectural decoration industries choose it.

Color coated aluminum plate is used in the construction industry, so its quality is particularly important, and in order to ensure quality, then you need to polish your eyes when purchasing, and all aspects of its purchase should be rigorous

Thermal insulation color aluminum plate is commonly used in our construction, so we must maintain it before use, when it can better ensure its quality, otherwise there will be a similar white spot situation, this is because aluminum is a active metal, easy to be oxidized, resulting in a white alumina film, so the formation of the white spot we see, So what should we do about it?

For the strict surface requirements of the heat insulation color aluminum plate, how to avoid its surface white spots, so that the product finish and brightness is better, which is not only related to the processing process, but also closely related to the surface treatment process.

In fact, the main reason is very simple: washing is not thorough after oxidation, resulting in the formation of white spots on the surface after drying, the solution is to strengthen the washing after oxidation, try to choose to wash thoroughly with a water gun.
