Basic Information

Aluminum profiles are classified by surface treatment
1. Anodizing, electrochemical oxidation of metal or alloy. The process in which aluminum and its alloys form an oxide film on aluminum products (anodes) under the corresponding electrolyte and specific process conditions under the action of an applied current.
The main uses are:
(1) Improve the wear resistance, corrosion resistance and weather corrosion resistance of parts.
(2) The transparent film produced by oxidation can be colored to make various colored films.
(3) As a capacitor dielectric film.
(4) Improve the binding force with the organic coating, as the bottom layer of the coating.
(5) As the bottom layer of electroplating and enamel.
(6) Other applications under development, such as solar absorbing panels, ultra-high hard films, dry lubricating films, catalyst films, nanowires, and deposition of magnetic alloys in porous films as memory elements.
2. Electrophoresis, electrophoresis is the electrophoretic coating on the cathode and anode, under the action of voltage, the charged coating ions move to the cathode, and interact with the alkaline substance produced on the cathode surface to form insoluble matter, which is deposited on the working surface.
3. Powder spraying, powder spraying is to use powder spraying equipment (electrostatic spraying machine) to spray powder coating on the surface of the workpiece. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating; powdery The coating is leveled and cured by high temperature baking, and becomes the final coating with different effects.
4. Wood grain transfer printing, the wood grain is transferred to the surface of the workpiece by thermal transfer printing. It is not easy to fade, and the wood grain is realistic, which improves the quality of the product. Widely used in: aluminum alloy doors and windows, anti-theft doors, fire doors, steel and wood furniture, filing cabinets, computer casings, household appliances, metal decorations, etc.
5. Fluorocarbon spraying, a kind of electrostatic spraying, is also a liquid spraying method, called fluorocarbon spraying. It belongs to high-grade spraying, which has a higher price and has long been used abroad. Fluorocarbon spraying has excellent fading resistance, frost resistance, corrosion resistance to air pollution (acid rain, etc.), strong UV resistance, strong crack resistance and can withstand harsh weather conditions. It is beyond the reach of general coatings.
The process flow of fluorocarbon spraying is:
Pre-treatment process: degreasing and decontamination of aluminum → water washing-alkali washing (degreasing) → water washing → pickling → water washing → chromization → water washing → pure water washing
Spraying process: Spray primer→topcoat→finish paint→baking (180- - 250°C)→quality inspection
The multi-layer spraying process consists of three sprays (referred to as three sprays), spraying bottom paint, top coat and finish paint, and secondary spraying (primer, top coat).
1. The purpose of pretreatment: Before spraying aluminum alloy profiles and plates, the surface of the workpiece must be degreased, decontaminated and chemically treated to produce a chromium film, increase the bonding force and oxidation resistance of the coating and the metal surface, and benefit Extend the life of the paint film.
2. Primer coating: As a primer coating for sealing the substrate, its function is to improve the coating's anti-penetration ability, enhance the protection of the substrate, stabilize the metal surface layer, and strengthen the adhesion between the topcoat and the metal surface, which can To ensure the color uniformity of the topcoat coating, the thickness of the paint layer is generally 5-10 microns.
3. Topcoat coating: The topcoat coating is a key layer of the spray coating, which is to provide the decorative color required by the aluminum, so that the appearance of the aluminum can meet the design requirements, and protect the metal surface from the external environment, acid rain, Erosion from pollution, prevents UV penetration. The anti-aging ability is greatly enhanced. The top coat is the thickest paint layer in spraying, and the thickness of the paint layer is generally 23-30 microns.
4. Finish paint coating: Finish paint coating is also called varnish coating, the main purpose is to more effectively enhance the paint layer's ability to resist external erosion, protect the finish paint coating, increase the metallic luster of the finish paint color, and make the appearance more colorful Bright and dazzling, the coating thickness is generally 5-10 microns. The total thickness of the three-spray coating is generally 40-60 microns, which can be thickened for special needs.
5. Curing treatment: The three-spray coating generally needs secondary curing, and the aluminum material enters the curing furnace for treatment. The curing temperature is generally between 180'C-250C, and the curing time is 15-25 minutes. Different fluorocarbon coating manufacturers, They will provide the best temperature and time according to their own paint. Some chlorocarbon spraying factories (curium oil factories) also changed the two-time curing to one-time curing based on their own experience.

FAQ

Q: How to place an order?
A: First let us know your requirement or application.
Secondly, we quote according to your request or our suggestion.
Third, the customer confirms the sample and makes a deposit for the formal order.
Finally we arrange production.

Q: Are all color products the same finish?
A: No. With powder coatings, bright colors will be higher than white or gray. Regarding the price of anodizing, the color will be higher than the silver, and the black will be higher than the color.
