1. Strengthen the process and strictly implement the operating procedures. Check the operation status every day and observe the process parameters at any time. Do not allow the workpiece to stay in the equipment to avoid rust.
2. Pay attention to the quality of washing. Aluminum profile in order to reduce the degree of pollution, first of all should minimize the workpiece entrainment cleaning fluid pollution next process. In addition, multi-stage water washing should be considered, generally secondary water washing, and some processes are still washed with pure water. After the first stage of washing water stain is not more than one tenth of the previous stage of cleaning the workpiece, so that the residual liquid concentration of the second stage of washing the workpiece is only one percent of the original concentration. When adding clean water, countercurrent supplement is used to save water.
3. Foam and its control. In metal cleaning, the corresponding amount of foam is beneficial to some processing processes, but the quality of industrial aluminum profile cleaning agent does not depend on the amount of foam, and in the injection, the cleaning agent is required to be low foam, otherwise the mass production can not be normal.
4. Recipe of oil remover. Because a single group of cleaning agent effect is poor, so the production of industrial aluminum profiles generally use multi-component, composite cleaning agent, because by strong alkali, weak alkali, polymerized inorganic salt, surfactant and other appropriate with the cleaning agent, can have to play their own cleaning characteristics, thus can significantly improve the cleaning efficiency.
