How to eliminate the influence of aluminum plates in sri lanka hard anodizing on the quality of the oxidized surface? The anodizing of aluminum alloy is a very common aluminum plates in sri lanka Surface treatment method, which can generate a dense anodic oxide film on the aluminum surface to protect the aluminum substrate and obtain the characteristics of corrosion resistance, wear resistance and non-conductivity. There is also a hard anodizing in aluminum alloy anodizing. How to eliminate the influence of hard anodizing on the quality of the oxidized surface?
How to eliminate the influence of aluminum plates in sri lanka?
1) Before treatment: oil surface aluminum plates in sri lanka product processing, there is a layer of oil on the surface, oil stains, can be divided into two types, saponified oil and saponified oil. Vegetable oil and animal fat can be dissolved and alkali saponification reaction, called saponified oil. Various mineral oils, such as anti-rust oils, lubricating oils, etc., emulsify alkali in the non-saponification reaction. Commonly used degreasing methods include organic solvent degreasing, chemical degreasing, electrochemical degreasing and degreasing.
2) Oxidized surface pretreatment: chemically or electrochemically etched aluminum plates in sri lanka oxide film on the surface of the overall corrosion products, the etching process can be divided into improved photo-etching surface brightness, removing the acid immersion of the surface passivation film , Activate the metal surface, remove the thick oxide film and the strong erosion of the skin.
3) Rough surface pretreatment: aluminum plates in sri lanka rough surface can be achieved by mechanical, chemical and electrochemical pretreatment methods. The polishing mechanical method that is often used to remove roughness and mechanical defects on the surface of the part can be selected according to different requirements, different materials, and different particle sizes of abrasives. Coarse and fine polishing, polishing can reach the degree of mirror brightness and fine polishing. Chemical polishing is a method of electrochemical polishing anodized electrolyte in a specific solution to the etching process, in order to obtain a mirror gloss. Other processing methods and sandblasting, brushing, etc.
