Technical Field

[0001] The invention relates to the field of preparation and processing control of an impregnation liquid for metal treatment, and in particular to a preparation and processing control system of an impregnation liquid for metal treatment. Background Art

[0002] Metal treatment impregnation fluid is a chemical solution used to improve the surface properties of metals. The impregnation process involves immersing the metal in the solution so that the active ingredients in the solution penetrate the metal surface and react chemically with it, thereby changing the properties of the metal surface. It is usually used for metal processing, surface treatment and lubrication. Metal treatment impregnation fluid can improve the surface quality and durability of metals and extend the service life of metals.

[0003] Monitoring the preparation process of metal treatment impregnation liquid can ensure product quality, safety and cost control, improve production efficiency, and is of great significance to the smooth progress of the production process and the stability of product quality.

[0004] There are some shortcomings in the existing monitoring methods for the preparation of impregnation liquid for metal treatment: First, when initially setting the process parameters for the preparation of impregnation liquid for metal treatment, they are often set based on the experience of the operator, which is subjective and does not combine the characteristics of the raw materials, such as dosage and material, to conduct quantitative analysis to obtain matching process parameters. As a result, the setting of process parameters is not reliable enough, which can easily make the production quality of the impregnation liquid for metal treatment unqualified or reduce production efficiency.

[0005] Secondly, after the process parameters for preparing the impregnation liquid for metal treatment are running according to the set initial values, the actual production situation is not monitored in real time. Due to the influence of factors such as equipment aging, production environment, and raw material quality, the actual production status may not meet expectations. At this time, it is necessary to dynamically correct the initially set process parameters, which makes the existing method for regulating the process parameters not very accurate and unable to guarantee the production quality and production efficiency of the impregnation liquid for metal treatment.

[0027] As a preferred solution, the relationship between the stirring parameters of the impregnation solution preparation process and the raw material information of the impregnation solution for metal treatment can be presented in the form of a table, a graph, a function, etc.

[0028] The raw material information for preparing the impregnation liquid for metal treatment is obtained, and the types and amounts of the impregnation agent and solvent for preparing the impregnation liquid for metal treatment are obtained, and the information is substituted into the prediction model of the stirring speed, stirring time and stirring temperature of the impregnation liquid preparation process to obtain the reference stirring speed, reference stirring time and reference stirring temperature of the impregnation liquid preparation process.
