The matt degree of the electrophoretic coating for aluminum profiles can be adjusted by changing the ratio of high-gloss paint and matt paint, which produces a matt effect. The principle of making matting electrophoretic paint is as follows. (1) Disperse ultrafine silica in the coating to achieve low gloss. However, the alkali-resistance of ultra-fine silicon dioxide is poor, and it can not obtain a good transparent coating film. For the coated object with complex coating construction, ultra-fine silicon dioxide will deposit on the coated object, so there will be differences in gloss and other defects in some areas of the coated object, especially in the vertical plane.
(2) The editor of Hengxing Paint also knows the method of dispersing organic particles with small density into the paint. This method is practical for solvent-based coating or impregnation-based coating, but for the electrophoretic coating of aluminum profiles, the electrophoretic property of the organic particles should be considered, that is, the constant rate swimming property after power on, and whether the organic particles will fall off when washing.
(3) The insoluble micro gel in particles is formed in the resin for electrophoretic coating, so as to achieve low gloss.

1. Chemical oxidation
At a certain temperature, a thin oxide film is formed on the surface of aluminum alloy profile through chemical reaction, which is called chemical oxidation of aluminum. This method does not need to pass through current, and the process is simpler and cheaper than electrochemical oxidation. The oxide film is very thin, and the film thickness is 0.5~4 μ M or so, the film is soft and has low wear resistance, so it cannot be used alone. The film has good physical adsorption capacity and is a good primer. The protective layer obtained by chemical oxidation can greatly improve the protective ability of parts.
2. Anodic oxidation method
Anodizing of aluminum alloy profile is made by electrolysis in oxalic acid, sulfuric acid and chromic acid aqueous solution with aluminum or aluminum alloy as anode and lead, carbon or stainless steel as cathode. Electro anodic oxidation can obtain film-forming speed that is difficult to obtain by natural oxidation. In the process of oxidation film formation, two processes occur at the same time: one is the formation of Al2O3 oxide film on the surface of aluminum plate; Second, the formation process of oxide film is accompanied by the dissolution of oxide film. Only when the formation rate of the oxide film exceeds its dissolution rate can a certain thickness of the oxide film be obtained, and the thickness of the film is generally 5~15 um. The film is a double-layer structure consisting of a dense barrier layer and a porous layer with a columnar structure. Anodic oxidation films of aluminum alloy profiles can be divided into two categories: porous films formed in acid electrolyzers such as sulfuric acid and oxalic acid, forming micropores perpendicular to the surface; Barrier film is a porous and extremely thin film formed in electrolyte, such as ammonium borate, which is commonly used in electrolytic capacitors.
The aluminum alloy doors and windows we often say refer to the doors and windows made of aluminum alloy extruded profiles, window frames, mullions, and sashes. They are called aluminum alloy doors and windows, and are now also referred to as aluminum doors and windows. Compared with doors and windows made of other materials, aluminum alloy doors and windows have natural advantages.
01. Aluminum alloy doors and windows have light deadweight and high strength:
Aluminum alloy materials are mostly hollow thin-walled composite sections, which are easy to use, reduce weight, have a density of only 1/3 of steel, and the section has high bending strength. The doors and windows made of aluminum alloy materials are durable and have little deformation.
02. Good sealing performance of aluminum alloy doors and windows
The airtightness directly affects the use function and energy consumption of doors and windows. Sealing performance includes air tightness, water tightness, heat insulation and sound insulation.
03. Beautiful appearance of aluminum alloy doors and windows
After anodizing, the aluminum alloy surface can show the colors of ancient lead liver copper, gold, silver white, etc., which can be selected at will. The oxidized surface is bright and bright. The window sash frame is large and can be inlaid with large area of glass, which makes the indoor light sufficient and bright, enhances the contrast between the virtual and real facades between indoor and outdoor, and makes the room more layered.
