Aluminum profiles of different surface treatment products

Aluminium profiles are aluminum materials that are made of aluminum rods that are hot melted, extruded, and thus have different cross-sectional shapes. In order to improve the decorative effect, enhance the corrosion resistance and prolong the service life, aluminum profiles are generally subjected to surface treatment. There are numerous production lines for aluminum profiles in JLG, covering surface treatment methods such as oxidation, electrophoresis, spray coating, fluorocarbon, thermal transfer wood grain and thermal insulation (through-bar and plastic injection), etc. The physical and chemical properties of each product are superior. .

1

Substrate

Untreated aluminum alloy surface.

Anodizing, coloring profiles

Oxidation is the substrate as the anode, placed in the electrolyte for electrolysis, the substrate surface to form a protective oxide film. Has strong wear resistance, weather resistance, corrosion resistance, strong hardness, anodized after electrolysis can be carried out, with the increase in color time, the color from light to dark. Can produce a variety of colors. The types of polychromatic anodization are silver, glossy silver, white oxide, bronze (No. 1 to No. 5) from light to black and other colors. Suitable for a variety of construction, industrial materials production.

Electrophoretic paint profiles

Electrophoretic coating is based on the anodization, through the role of electrophoresis on the oxide film covered with a layer of water-soluble acrylic paint film. Therefore, the surface layer of the electrophoresis profile is a composite film of anodized film and water-soluble acrylic film. It has better corrosion resistance, weather resistance and wear resistance than anodizing, and the profile surface is more smooth and beautiful. Poly Grid electrophoretic paint color types are silver, matte silver, champagne, frosted champagne, pearlescent electrophoresis and so on. Suitable for outdoor buildings or vehicle parts.

4

Powder spray profile

The coating has good adhesion, weather resistance, peeling resistance, and strong UV-resistance. The existing powder coating coloring types can be used in a variety of colors, and color matching can be performed. Rich colors provide designers with a vast design space.

5

Fluorocarbon paint spray profile

It has the extraordinary function of resisting bad weather, resisting the erosion of acid and alkali and being free from air pollution, ozone and acid rain. Fluorocarbon coatings are uniform in color and have excellent resistance to fading and staining. Even if the building is expanded many years later, old and new colors can still be perfectly matched. There are thousands of colors available for fluorocarbon spray coloring, which can be used for color grading. Fluorocarbon paint spray coating types include two coats (primer plus top coat), three coats (primer, top coat plus varnish), four coats (primer, barrier paint, top coat plus varnish).

Broken Bridge Insulation Energy-saving Profile

A low thermal conductivity spacer is inserted between the inner and outer aluminum alloys of high thermal conductivity, so that an effective thermal insulation layer is formed between the inner and outer sides of the aluminum alloy section, so that the way to dissipate heat through the door window frame or the window sash profile is Cut off, to achieve high energy efficiency of the purpose of heat insulation, this isolation is called "bridge insulation" or "hot cold bridge." The thermal conductivity of insulated aluminum alloy doors and windows is 40% to 70% lower than that of non-insulated aluminum alloy doors and windows. Insulation profiles are divided into strip-type insulation profiles and cast insulation profiles.

7

Wood profile

Woodgrain transfer is used as a surface treatment method for re-engraving various wood grain textures on the surface of aluminum profiles. The surface of the product after woodgrain transfer has a very realistic wood grain processing effect. The three-dimensional effect is strong, and it can better reflect the nature of wood grain. Feel that anti-aging fade, corrosion resistance, weather resistance, is an ideal energy-saving and environmentally friendly material to replace the traditional wood, in line with the current advocacy of "aluminum on behalf of the wood" of the green concept.

Surface treatment is an indispensable and extremely important process for the production of aluminum alloy profiles. The surface of aluminum alloy profiles is rich and colorful. Various colors of Hing Fat Aluminum are available for customers to choose. The future aluminum surface treatment technology will be more in line with the development trend of building curtain walls. It puts forward higher requirements for technological development, energy conservation and environmental protection, and safety and cleanliness.
