ã€China Aluminum Network】 Industrial aluminum spray cleaning method is widely used, due to complex equipment, high process requirements, poor cleaning effect, then how to do a good job cleaning industrial aluminum spray:
1, to strengthen the process, and strict implementation of operating procedures.
Check the operation status every day and observe the process parameters at all times. Workpieces are prohibited from stagnating in the equipment to prevent rust.
2, pay attention to the quality of washing.
In order to reduce the degree of pollution, aluminum profiles should first minimize the contamination of the next process by the entrained cleaning solution. In addition, multi-stage washing should be considered, which is generally secondary washing, and some processes still use pure washing. The level of water used for cleaning in the next stage is not more than one-tenth that of the previous stage, so that the concentration of residual solution in the second-stage washing is only one percent of the original concentration. When adding clean water, use countercurrent supplements to save water.
3, foam and its control.
In metal cleaning, the generation or removal of foam is very important for the pre-treatment process. A certain amount of foam is beneficial to certain treatment processes, but the quality of industrial aluminum profile cleaning agent does not depend on the amount of foam, but in the past. When spraying, the cleaning agent is required to be low foaming, otherwise mass production cannot be performed normally.
4, degreasing agent formula.
Due to the poor effect of a single set of cleaning agents, multi-component, compound-type cleaning agents are generally used in the production of industrial aluminum extrusions, because of the proper combination of strong alkalis, weak bases, polymeric inorganic salts, surfactants, etc. The agent can exert its own cleaning properties, which can significantly improve the cleaning efficiency.
