powder coating MATT BLACK aluminum profile

In the application of aluminum alloy profiles, matte spray black surface treatment is a common and effective process. It not only provides a beautiful appearance, but also increases functionality. The following are the applications of this process in various fields as well as the specific process flow and advantages:

1. Application field

Electronic equipment radiator

Heat dissipation performance: The black matte surface helps to improve the radiation heat dissipation performance and is suitable for radiators of high-power electronic equipment.

Anti-corrosion: Spraying treatment enhances the corrosion resistance of aluminum alloy and is suitable for electronic equipment in humid or harsh environments.

Architectural decoration

Beautiful appearance: The black matte surface has a modern and high-end feel and is widely used in building exterior wall decoration, door and window frames, etc.

Weather resistance: Enhances the weather resistance of the material to prevent aging and discoloration caused by long-term exposure to sunlight and rain.

Automotive industry

Parts: Used for automotive exterior and interior parts such as roof racks, pedals, dashboards, etc., providing beauty and durability.

Lightweight: Aluminum alloy materials help to lighten the car, reduce fuel consumption, and improve fuel efficiency.

Furniture manufacturing

Frame structure: Used for the frame and bracket of modern furniture, the matte black surface enhances the overall texture of the furniture.

Durability: Provides a wear-resistant and scratch-resistant surface to extend the life of furniture.

Consumer Electronics

Casings and Frames: Used for the casings and frames of consumer electronic products such as mobile phones and laptops, which are beautiful and have a good feel.

Shielding Interference: The black matte surface can reduce electromagnetic interference and help the performance of electronic products.

2. Process Flow

Pretreatment

Cleaning: Remove oil, dust and oxides from the surface of the aluminum alloy to ensure the surface is clean.

Polishing: Mechanical polishing or chemical polishing to eliminate surface defects and provide a smooth base.

Frosting

Sandblasting: Use a sandblasting machine to spray abrasives (such as aluminum oxide sand or glass beads) onto the surface of the aluminum alloy to form a uniform frosting effect.

Adjusting Roughness: Adjust the type of abrasive and the spraying pressure according to needs to control the surface roughness.

Spraying Primer

Primer Spraying: Spray primer on the frosted surface to improve the adhesion and durability of the coating.

Baking and Curing: Curing the primer to improve its adhesion and corrosion resistance.

Black Spraying

Paint Selection: Use high-quality black paint to ensure uniform coating and full color.

Spraying process: Electrostatic spraying or painting process is used to ensure that the paint is evenly covered on the frosted surface.

Baking and curing: Bake and cure again to ensure the hardness and wear resistance of the coating.

Surface treatment

Cleaning: Remove the spray powder or impurities remaining on the surface.

Inspection: Check the surface uniformity, color consistency and defects to ensure quality.

III. Advantages

Improve heat dissipation performance

The black frosted surface increases the radiation heat dissipation capacity, which is particularly suitable for high-power electronic equipment.

Enhanced corrosion resistance

The coating formed by the spraying treatment effectively prevents the oxidation of aluminum alloy and adapts to various environments.

Beautiful and durable

The black frosted surface has a high-end, modern appearance, and is wear-resistant and scratch-resistant, suitable for decorative and practical occasions.

Reduce reflections

The frosted treatment reduces the reflection of the surface, which is particularly suitable for applications that need to avoid glare, such as display device housings.

Good feel

The frosted surface provides a comfortable feel, suitable for parts that require frequent contact, such as electronic products and furniture.

Through the above process flow and advantages, black frosted sprayed aluminum alloy profiles have been widely used in many fields, which not only improves the functionality of the product, but also provides an elegant appearance design.
