Coated Aluminum Coil Gloss And Smoothness

Caitu aluminum tape is the surface of the coating after the treatment of aluminum and aluminum alloy strip, aluminum and aluminum alloy plate with deep processing products. Coated Aluminum Coil He is divided into polyester color coated aluminum (PE) and fluorocarbon coated color coated aluminum (PVDF).

Polyester color coated aluminum (PE) is an anti-UV UV coating for interior decoration and advertising boards. Polyester resin is the use of the main chain of ester bond-containing polymer as a monomer, Coated Aluminum Coil add alkyd resin. It can give a rich color of aluminum products, Coated Aluminum Coil but also has a good gloss and smoothness, as well as superior texture and feel, but also can increase the sense of hierarchy and three-dimensional.

Fluorocarbon coated color coated aluminum (PVDF) fluorocarbon coatings are PVDF resins mainly refers to the vinylidene fluoride homopolymer or fluorophene and other small amount of fluorine-containing vinyl monomer copolymer coating. Especially in harsh climates and the environment showing long-lasting anti-fading, anti-UV performance. Coated Aluminum Coil Particularly suitable for public places in the indoor, Coated Aluminum Coil outdoor decoration, commercial chain, exhibition advertising and other decoration and display.

Caitu aluminum is widely used in building decoration, Coated Aluminum Coil food packaging, electronic appliances, printing, transportation and other fields. Here we look at the specific application of color coated aluminum:

Building Decoration: manufacturing roof panels, Coated Aluminum Coil roof panels, curtain wall panels, interior wall panels, ceiling ceiling panels, honeycomb panels, thermal insulation panels, shutter doors, shutters and so on.

Food packaging areas: the manufacture of non-pressure food cans, Coated Aluminum Coil pressure food cans, cans, caps, lid, pull ring, food boxes, all kinds of food packaging sealed bags.

Electrical and electronic areas: manufacturing air-conditioning panels, Coated Aluminum Coil washing machine panels, refrigerator panels, cabinets panels, all kinds of digital electronic products shell.

Transportation: manufacturing box-type truck shell and inner wall, Coated Aluminum Coil car body panels, train car panels, ship interior panels, traffic signs signs, advertising panels, luggage.

Polyester color coated aluminum, for example, why increase the adhesion of aluminum surface coating performance, the coating before the material on the pre-treatment, Coated Aluminum Coil the current market more chromic acid and silica system chromium-containing passivation A coating treatment is carried out, Coated Aluminum Coil or a chemical reaction film for imparting a phosphate system is applied.

Chromate is highly toxic and carcinogenic, colleagues in the process of chromate passivation process of aerosol and other harmful to workers, the discharge of waste water seriously pollute the environment. As a result, Coated Aluminum Coil countries around the world have in recent years made increasingly stringent restrictions on the use of chromate and waste water emissions in environmental regulations.

The reactive type of film, Coated Aluminum Coil there are more inconvenient construction, such as the need for sewage treatment and other issues.

Therefore, the development of the coating type of chrome-free aluminum passivation is necessary.
