Industrial aluminum profiles are widely used as raw materials in many fields. But in the production process, it is not so easy, often due to a variety of factors, so that the aluminum profile is not so extreme. In which the aluminum profile is very easy to air oxidation, is a vexing problem, to deal with such things should be how to deal with it?

        (1) Aging. The aging mode of aluminum profile can be decided according to the climate conditions. In the summer of sunlight, it can be exposed to sunlight, and in the rainy day or winter, it can be baked by drying box. The processing standard is: the temperature is 40 ~ 50℃ for 10 ~ 15min.

        (2) Wash with boiling water. Boiling water is used to wash the aging film. But the temperature and time should be strictly controlled, the temperature is too high to thin the film layer, the tone becomes shallow. Industrial aluminum profile solution time is too long will also occur above similar problems, suitable temperature and time is: temperature 40 ~ 50℃ time 0.5 ~ 1MIN.
