Industrial aluminum jet cleaning method is widely used, due to complex equipment, high process requirements, in order to ensure the best pre-treatment effect, we must strengthen management from the following aspects:
1. Strengthen the process management, strictly enforce the operating procedures, check the operating status every day, always observe the process parameters. Prohibit the workpiece stagnated in the equipment, so as not to rust.
Pay attention to the quality of washing, the workpiece in the degreasing process, the surface with residual liquid, if not washed, affecting product quality. Therefore, the residue must be washed off the surface of the workpiece is called washed. In industrial production, in order to save water, the washing water is usually recycled, so the washing water will gradually be deteriorated by the cleaning agent. Aluminum profiles in order to reduce the degree of pollution, first of all should be to minimize the workpiece entrainment cleaning fluid pollution under the procedure. In addition, multi-level washing should be considered, generally two washing, and some processes or pure water washing. The last level of washing water stains no more than one-tenth of the cleaning of the previous stage, so that the second-level cleaning of the workpiece is only the original concentration of the residual concentration, one percent. When adding clean water, countercurrent supplement, to save water.
3. Foam and its control. In metal cleaning, the generation or removal of foam is important to the pretreatment process. A certain amount of foam is advantageous for some treatment processes, but the quality of industrial aluminum cleaners does not depend on The amount of foam, and spray in the future, requires low-foam cleaning agent, or mass production can not be normal. Common defoaming methods by: adding defoamers; low foam surfactant; temperature control; reduce the air mixed with other.
In addition to oil formulations, as a result of a single group of poor cleaning agent, so the production of industrial aluminum rarely used, the general multi-component, complex type of cleaning agent, because the strong base, weak base, inorganic salts, the surface Active agent and other appropriate combination of cleaning agents, can have their own wash performance characteristics, which can significantly improve the cleaning efficiency. Especially after adding a small amount of surfactant, the cleaning efficiency can be doubled. The formula of industrial aluminum cleaner can be experimentally determined according to the type of oil to be cleaned, the material of the aluminum workpiece, and the cleaning method.
