Composition of aluminum veneer
Aluminum veneer suggests that it is the plate material made of aluminum or aluminum alloy, or plate type aluminum product heated by flat aluminum embryos made by the process of heating, rolling and straightening or solid solution aging. A variety of spraying surface colors are available, good strength, low-cost, long life, if not direct contact with steel, aluminum veneer will not fall off and corrode in 50 years hanging on the wall.
Aluminum veneer is used for architectural decoration works
Aluminum veneer used in building includes single-layer aluminum veneer, composite aluminum veneer a variety of materials, which generally often refers to single-layer aluminum veneer (also called single aluminum veneer or pure aluminum veneer), used for architectural decoration works, In recent years, single-layer aluminum is used more common in aluminum plate curtain wall. Anodized oxide film is generally more than 12µ, the color is only available for bronze and white, the color is monotonous; the more serious drawback is that each block of aluminum single plate board surface color shade is different; the overall effect of curtain wall formed by the combination of many blocks of curtain wall panels together is very ugly.
The single-layer aluminum veneer is best for aluminum veneer curtain wall material
Single-layer aluminum veneer is easier to bend, processing and form complex shapes than honeycomb aluminum veneer, which is better able to adapt to the endless changing demand of the building's exterior decoration. It is generally believed that the single-layer aluminum sheet is best for aluminum veneer curtain wall material. Liquid spray coating is the fluorocarbon polymer spray coating, commonly known as carbon fluoride sprayed coatings, is the fluorocarbon polymer resin for the manufacture of paints for metal finishes, the combination with the fluorine is the most solid molecules. Because aluminum veneer is not the batch number, chemical composition has a small difference, in addition, the upper oxide electrolyzer liquid current density and other factors cannot be completely the same, so the oxidized color may have differences. It may not be obvious if you see leaflets, if all row together that is very obvious. The spray powder is collide resistant and friction resistant, the aluminum veneer deforms under the impact of 50 kg, spraying layer has no cracks, no off layer and intact, resistant to dilute acids and mortar.
Pay attention to select powder spray coating
Aluminum veneer thickness is reduced from 3mm to 2.5mm; the alloy strength is about twice as pure aluminum veneer. Aluminum veneer thickness is 3mm, to strengthen the aluminum single plate board surface strength, the strengthen tendons must be installed in the back of the aluminum veneer ribs (upset existing manufacturers don’t install), which is made with thick aluminum. Weld the dolphin screw cap at the back of the aluminum veneer by flash welder, and then set aluminum drilling stiffeners into the screw. The single aluminum veneer generally uses aluminum veneer. The spray powder produced by many domestic manufacturers has very large weight difference, and some powder contains auriferous crumbs. This powder has change at day and in the evening, with the sun angle change after hanging to the wall; the wall color depth is different. So we should pay attention when selecting powder spray coating.
