wood pallet fumigation-free export packaging, color coated aluminum roll (embossed color coated aluminum roll) : (polyester color coated aluminum roll, fluorocarbon color coated aluminum roll)

Thickness 0.024-1.2(mm) Width 800-1220(mm) Material 1100 1060 3003 5052, depending on the material.

Color coated aluminum plate used for aluminum profile, thickness, strength and oxide film, should conform to the relevant national standards, wall thickness should be more than 1.2 mm, tensile strength to reach 157 Newton per square meter of millimeter, yield strength to reach 108 Newton per square millimeter, oxide film thickness should reach 10 microns. If not up to the above standards, is inferior aluminum alloy doors and Windows, can not be used.

Two, look at the processing.

Color coated aluminum plate, fine processing, exquisite installation, good sealing performance, switch freely. Poor aluminum alloy doors and Windows, blind selection of aluminum series and specifications, processing shoddy, to saw cutting instead of milling processing, do not install according to the requirements, poor sealing performance, switch is not free, not only air leakage and rain and glass cracking phenomenon, but also encounter strong winds and external forces, easy to push and pull part or glass scraping or crashing down, damage damage.

Three, look at the price.

Under normal circumstances, color coated aluminum plate because of high production cost, the price is about 30% higher than inferior aluminum alloy slide. At present processing color coated aluminum plate more self-employed, they do not know the aluminum alloy anti slide structure characteristics and performance. In order to reduce the cost of jerry-building, shoddy products, hidden dangers are larger, generally not suitable for use. Can choose regular manufacturers of products.

Usually, when choosing color coated aluminum plate, we should first look at its material, some manufacturers cut corners, and the material is not good, so we must know the choice of material, and then to ensure the quality, followed by the production process.

How to remove the white spot of heat insulation color aluminum plate

Heat insulation color aluminum plate is commonly used in our buildings, so we must maintain it before use, when it can better ensure its quality, otherwise there will be a similar white spot, this is because aluminum is active metal, easy to be oxidized, thus generating a white alumina film, so the formation of the white spot we see, So how do we deal with it?

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

In fact, the main reason is very simple: after oxidation washing is not thorough, resulting in the formation of white spots on the surface after drying. The solution is to strengthen the washing after oxidation, as far as possible to choose to wash thoroughly with a water gun. At the same time, after washing should pay attention to protect the surface, try to let the product do not contact other products, natural air dry.
