The outer layer of aluminum oxide film pattern in contact with the electrolyte chemical dissolution. General requirements for the first organic solvent (e.g., kerosene, gasoline, trichlorethylene, carbon tetrachloride, etc.) of crude degreased, and then transferred to the chemical degreasing. Good thermal stability of the aluminum alloy profiles, at 300 ~ 500 ℃ condition, its strength is about 10 times higher than aluminum. The main reason is the high porosity joints, weld quality requirements can not be satisfied. It is widely used in various industries. This film is formed early enough fine Corrugated aluminum supplier, although some resistance Corrugated aluminum, but the negative oxygen ions in the electrolyte can still reach the surface continues to form an aluminum oxide film which is to be at least twice to go through the step of washing called in and after washing This washing we recommend using circulating water cleaning supply Corrugated aluminum manufacturers, that the purpose is to protect the normal time by oxidation tank, and the tank because the nitric acid, which if is brought into oxidation tank, then there may not form an oxide film Corrugated aluminum manufacturer, or an increase in impurity oxidation tank, this will accelerate the aging oxidation tank. Simple washed twice, after chemical polishing . washing after chemical polishing will from some residual liquid, for better cleaning, small advice to use a second circulating water tank, the first tank to keep the temperature on the line Corrugated aluminum |. Corrugated aluminum supplier | aluminum rolls industry provided by the Aluminum Co., Ltd. Jinan Heshun. Jinan Heshun Aluminum Co., Ltd.
