Anodic oxidation, electrophoretic coating and powder spraying are the main surface treatment methods of aluminum profiles. Each method has its own advantages and occupies a considerable market share. But if you want to divide the high and low, personally think or spraying powder dominant, what are the advantages?

Advantage 1

The process is relatively simple, mainly due to the improvement of the automatic precision of the main equipment in the production process, some of the main technical parameters have been able to achieve microcomputer control, effectively reducing the difficulty of process operation, while greatly reducing the auxiliary equipment;

Advantage 2

High yield, in general, if the appropriate measures, can maximize the control of nonconforming products;

Advantage 3

The energy consumption is obviously reduced. In the production process of ordinary anodic oxidation and electrophoretic coating, the consumption of water and electricity is quite large, especially in the oxidation process. The output current of the rectifier can reach 8000~11000A, and the voltage is between 15~ 17.5v. In addition, the heat consumption of the machine itself needs to be constantly cooled by circulating water. The power consumption per ton is usually around 1000 degrees.

Advantage 4

The pollution degree of water and air is reduced, the use of flake alkali, sulfuric acid and other liquid organic solvents is no longer used, reduce water and air pollution, but also effectively improve the competitive strength of aluminum profile and as an environmental protection product of plastic steel profile, reduce some production costs accordingly;

Advantage 5

The labor intensity of workers has been significantly reduced, because the use of automated assembly line operations, feeding methods and the use of fixture has been significantly simplified, improve the production efficiency, but also reduce the labor intensity;

Advantages 6

The requirements for the surface quality of raw materials are significantly reduced. The powder coating can completely cover the extrusion lines on the profile surface, cover up some defects on the surface of aluminum profiles, and improve the surface quality of aluminum profiles.

Advantages 7

Some of the physical indicators of the coating film than other surface treatment film has significantly improved, such as hardness, wear resistance, acid resistance, can effectively extend the service life of aluminum profiles.

Powder spraying is powder coating, process is used is electrostatic spraying, the use of electrostatic spray gun, under the influence of accelerating wind, so that the powder particles ejected gun body carrying a positive charge, and with a negative charge profile contact, electrostatic adsorption, and then through high temperature curing. It also enhances the adsorption strength of the coating and prevents the paint film from falling off.

Look from craft itself, have quite tall science and technology composition, allocate the coating of each different color, produce the adornment effect of different color department, accord with the need of indoor adornment more, also be with the application of aluminous profile in bldement to indoor development trend photograph is consistent. In particular, the combined use of spraying profiles and thermal insulation bridge, so that it has a more fashionable trend, thermal spray powder profiles with a greater space for development, but also other processing methods produced by the profile can not be replaced.
