The defects of the surface oxidation treatment process of aluminum profiles and home decoration aluminum cannot be ignored
Defects and solutions of aluminum surface oxidation treatment.
In the production process of aluminum products, the following defects often appear: 1. Stripe defects, such as black lines, 2. Surface spots, corrosion, 3. Surface oil pollution, different colors, etc., there are not many reasons for defects.
Oxidation treatment of aluminum surface spot defects.
Before oxidation, if the surface of aluminum is splashed with acid, alkali solution, or affected by acid mist, alkali mist, it is easy to appear white spots on its surface, and round spots will appear when the corrosion is serious, if there is no corrosion between crystals in its cross-section, it is alkali corrosion, and corrosion between crystals is acid corrosion, so the way to control aluminum is to try to put aluminum in a dry environment.
Corrosion after oxidation treatment on the surface of aluminum.
The presence of a small amount of chloride in the oxidation tank is easy to lead to the corrosion of aluminum, which is mainly caused by spot corrosion, the main influencing factors are temperature, alkali washing time, Fe content in the alloy composition, Si content, extrusion state of aluminum products, etc., in the thicker extrusion stripes, the spot corrosion has a certain directionality, because when the stress is concentrated, the crystal lattice changes, and the preferential precipitation of ions creates a strip of industrial aluminum for the subsequent production of spots.
According to the data survey, most families indoor air pollution is 5-10 times higher than outdoors, indoor pollution has become the cause of a number of diseases, and formaldehyde as a major aspect of indoor pollution, but also more and more attention to people, in the traditional wardrobe manufacturing process, particleboard, fiberboard, plywood these boards need to add many adhesives to form, and formaldehyde exists in these adhesives, which causes the inevitable problems of traditional furniture. The all-aluminum furniture is made of home decoration aluminum spliced furniture, which avoids the use of these adhesives and is a real zero formaldehyde healthy furniture.
The appearance is beautiful, the home decoration aluminum effect imitates solid wood, the color is natural and beautiful, because the home decoration aluminum is made of pure aluminum ingots, so he also has the characteristics of no rust and no fading, the product is long-lasting and beautiful, home decoration aluminum also has the characteristics of moisture-proof and waterproof, fundamentally effectively preventing moisture absorption and mold due to being in a humid environment, so that the product has the functions of waterproof, moisture-proof, radiation proof and so on.
Home decoration aluminum has excellent industrial design, simple installation, convenient construction, and also has the plasticity of aluminum profiles, this process can meet the customer's diverse choices of shape and color, and realize personalized formulation, industrial aluminum.
