Powder coated aluminium suppliers produce powder coated aluminium is to replace the paint coating with powder coating, powder coating has four major characteristics of high efficiency, energy saving, economy and environmental protection.
Powder coating has 100% solid content, no "three wastes" in the manufacturing process of powder coated aluminium, no need to add solvents to the process, using air as the dispersion medium, and utilizing high-voltage electrostatic adsorption for coating. This is the coating structure of high-performance powder coated aluminium sheet, the substrate is aluminum-magnesium-manganese alloy aluminum sheet. Depending on the corrosive medium of the environment, different coatings such as galvanized, aluminized zinc or galvanized aluminum-magnesium can be selected. On top of the coating is a chemical conversion layer, which adopts the passivation treatment technology of PAKA, Japan, to effectively ensure the strong adhesion of the coating. And the most surface is high-performance powder coating, according to the use and engineering design of different years, can choose SPE polyester, SDP super weathering polyester, DVDF fluorocarbon and other different coatings.
A 1.5mm thick powder coated sheet produced by powder coated aluminium suppliers, after doing 0T (180°) bending, the coating still has no cracking and peeling phenomenon. It is very difficult to achieve 0T coating without cracking and peeling off for such a thick coated aluminium sheet, which is difficult to do for the traditional painted aluminium sheet. This layer of "powder" is how to adhere to the surface of the metal substrate, and how to cure to form a dense hard coating? Let's walk into the powder coated aluminium production workshop of powder coated aluminium suppliers to find out.
Electrostatic powder color coating production line is the high-speed electrostatic powder coating production line with international advanced level introduced by HC Aluminum, with a total length of more than 230 meters, which can complete the front and back coating of metal plates at one time, and has an annual production capacity of 220,000 tons of powder coated sheetss. In the coating section, it is a relatively closed environment, which is commonly known as "powder room". The "powder room" is the core technology of this production line. Here, the treated metal substrate will pass through the powder coating device installed in the box, under the strong electrostatic field, high-tech coating equipment to produce paint "powder cloud", the metal substrate through the "powder cloud" at high speed, the powder particles are uniformly adsorbed on the metal substrate surface. Powder particles are evenly adsorbed on the surface of the metal substrate, and the thickness of the one-time coating film can be up to 120 microns or more. The substrate adsorbed on the dry powder film is cured at a high temperature to form an ultra-high density coating, which is then air-cooled by water cooling. In the completion of the process section of the processing at the same time, but also for the metal substrate "wear" can effectively resist the invasion of corrosion factor "gold armor". With this layer of "golden armor", color coated aluminum sheet corrosion resistance, aging resistance significantly improved, especially acid corrosion resistance is more than 5 times the traditional painted aluminum plate. Therefore, HC Aluminum high-performance powder coated aluminium plate is also known as the "golden armor" of the building metal enclosure.
With its superb corrosion resistance, powder coated aluminium suppliers high-performance powder coated plate is widely used in steel mills, power plants, chemical industry, papermaking, ceramics, animal husbandry, metal processing and other metal structure enclosure projects with high corrosion resistance requirements in strong acid, alkali and salt spray environments. The new generation of color coated sheet high-performance powder coated is becoming a brand new upgrade and alternative to the traditional painted color coated sheet.
