Gepoedercoate aluminiumplaat verwijst naar de aluminiumplaat die is verwerkt door middel van een poederspuitproces;
Powder coated aluminum sheet refers to the aluminum sheet processed by powder spraying process;
The purpose is to change the surface of the aluminum sheet, so that the surface has beautiful colors and patterns, and at the same time enhance the weather resistance of the aluminum sheet;
Powder coating is to spray a powder coating on the surface of aluminum alloy substrate through electrostatic action. The adhesion, weather resistance, peeling resistance, strong UV resistance and dense coating of the coating are incomparable to the surface treatment of general aluminum profiles. The spraying effect is superior to the spraying process in terms of mechanical strength and aging resistance, and the cost is also lower. Under spray paint with the same effect.
PE: polyurethaan, polyurethane resin, epoxy resin, hydroxyl polyester resin and epoxy polyester resin
PVDF: Fluorkoolstofcoating
Coating thickness: It can be divided into single coating (4μm-20 μm); double coating (25μm-28 μm); 3 coating (35μm-38μm).
Momenteel, the current situation of Our country powder coated aluminium sheet is that the production capacity of ordinary products is excessive, and the production capacity of high-tech, high-precision and high-quality products is insufficient, which also leads to a large number of imports.
Features of powder spraying: manual spraying equipment, automatic hanging type, simple construction, coating thickness of more than 30 micron, good impact resistance, abrasion resistance, corrosieweerstand, weather resistance, enz., the coating price is cheaper than fluorocarbon .
The biggest disadvantage of powder spraying is: fear of ultraviolet radiation from the sun, long-term exposure will cause natural fading, and the color difference between the sunny side and the non-sunny side of the door and window profiles will be obvious after a few years, usually within 2-5 jaren.
Loading → pretreatment (chromizing) → spraying → curing → dropping
Purpose of chromizing: to form a fine and stable chromizing film on the surface of aluminum. This film layer has a certain degree of wear resistance, corrosion resistance and good adsorption capacity, so that the paint can improve its adhesion when it is painted.
Curing: Powder spraying is baked and leveled at high temperature and cured to form a final coating with different effects; in powder spraying, the baking and curing temperature and time of powder coating play a decisive role in the curing performance of the coating film. Daarom, it is necessary to classify the objects to be sprayed reasonably through multiple tests to determine the number and arrangement of the pendants, as well as the corresponding baking and curing temperature and time, in order to ensure the quality of the coated product.

Powder coating of aluminum veneer is to use powder spraying equipment (electrostatic spraying machine) to spray powder coating on the surface of aluminum sheet, and there are many types of powder coating process. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powder coating; the powder coating is then baked and leveled at a high temperature to become a final coating with different effects (different types of powder coating effects). The spraying effect of powder spraying is better than that of spraying paint in terms of mechanical strength, adhesion, corrosieweerstand, aging resistance, enz. Compared with spraying paint with the same effect, the cost is lower.
Advantages of powder coating compared with traditional painting process:
Powder coating of aluminum sheets is a common surface coating technique that involves spraying fine powder paint onto the surface of aluminium platen through a spray gun, and then forming a solid coating during drying and curing. This technique has wide applications in many fields, here are some examples:
Construction and building materials: Powder coated aluminum sheets are commonly used in construction for the coating of exterior walls, window frames, doors, railings and other metal components. This coating provides weather and corrosion resistance, making the building structure more durable.
Household items: Household items such as furniture, lampen, door handles, enz. are also often used powder coating aluminum sheet technology to endow the products with rich colors and decorative effects.
Automobiles and vehicles: Powder coated aluminum sheets are used for surface coating of body, wheels, frame and other components in automobile manufacturing. This coating provides scratch resistance, corrosion resistance and improved appearance.
Electronic products: Powder coated aluminum sheets are also used on the casing and exterior parts of electronic products, such as computer casings, audio casings, enz., which can protect the equipment and give it a beautiful appearance.
Outdoor facilities: Seats and sunshade structures of outdoor facilities such as parks and squares can also use powder coated aluminum sheet technology to increase the durability and visual appeal of the product.
Industrial equipment: Mechanical equipment, pijpleidingen, storage tanks and other metal components in the industrial field can also be surface coated by powder spraying aluminum sheet technology to prolong service life and improve corrosion resistance.
Sports facilities: sports venues, fitness equipment, enz. can also use powder coated aluminum sheets for surface decoration and protection.
In het algemeen, powder coated aluminum sheets are widely used, mainly because they can provide metal surfaces with multiple functions such as durability, beauty, en corrosiebestendigheid, and are suitable for various industries and fields.
Honingraat aluminiumfolie, ook bekend als aluminium honingraatkern, is een soort lichtgewicht kernmateriaal gemaakt van twee lagen aluminiumfolie die zo aan elkaar zijn gehecht dat er een reeks zeshoekige cellen ontstaat, net als een honingraat.
