The color-coated aluminum plates produced by Henan Chalco use various grades of alloy aluminum plates as substrates, through surface pretreatment (degreasing, cleaning, chemical conversion treatment), coating with paint in a continuous method (roller coating method), baking and cooling White painted aluminum sheet has light weight, beautiful appearance and good corrosion resistance, and can be directly processed. It provides a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing, furniture industry, electrical industry, etc. It compresses the use of aluminum instead of steel. Aluminum instead of wood, construction, energy saving, pollution prevention and other good effects.
At present, the white painted aluminum sheet produced by Henan Chalco are divided into two categories: fluorocarbon sprayed aluminum plates and polyester painted aluminum plates.
Fluorocarbon sprayed aluminum plate: Fluorocarbon sprayed aluminum plate is an electrostatic sprayed aluminum plate, and also a method of liquid spraying aluminum plate, called fluorocarbon sprayed aluminum plate. It belongs to sub-spraying, the price is relatively high, and its technology has been applied abroad.
Polyester painted aluminum sheet is also called unsaturated polyester painted aluminum sheet. It is a kind of multi-component painted aluminum sheet. It is a thick painted aluminum sheet made of polyester resin as the main film-forming material. The paint film of the polyester lacquered aluminum plate is full, and the layer is thick and hard. Polyester varnished aluminum sheet has varnish varieties, called polyester varnished aluminum sheet. Polyester paint aluminum panels need to be cured during the construction process, and the amount of these curing agents accounts for one third of the total amount of paint. These curing agents are also called hardeners, and their main component is TDI (toluenediisocyanate). These free TDI will turn yellow, which not only makes the furniture paint surface yellow, but also makes the adjacent wall yellow. This is a major disadvantage of polyester painted aluminum panels.
