What We Need To Pay Attention To The Selection Of Filters？
TIME：2024-06-03 Author：admin Views：
In the electroplating filtration industry, frequently used filters have various flow of chemical liquid filters, chromic acid filters, chemical nickel filters and activated carbon filters, etc., widely used in surface treatment, electroplating, painting and other fields. So what are the precautions for the selection and use of pp filter?
In addition to chemical plating and chromium plating is because of the different types of plating and the nature of the work of the filter material to put forward special requirements, activated carbon cycle filtration and pre-plating de-oiling filter is the electroplating process to improve the new requirements of the equipment manufacturing enterprises, in particular, pre-plating de-oiling filter to ensure that the quality of electroplating workpiece processing of a key process.
Aluminum oxidation, passivation and phosphating with a bag filter, is another model of surface treatment, which is commonly used with the solution filter of the obvious difference is the use of the filter structure is different.
PP filter can be widely used in solution filtration with high solid impurity content and large particles, such as passivation, aluminum oxidation, phosphating and so on for pretreatment of steel parts. At the same time, this form of filter can also be used for the recovery of useful substances in the solution, which significantly improves economic efficiency, reduces costs and reduces emissions.
How to correctly select the model to meet the reasonable needs of the plating tank, which has the relationship between the proportion of the cycle, but also the plating tank processing volume, the nature of the workpiece and the relationship between the content of impurities brought in.
In general, the flow rate calibrated in the model of the filter, refers to the determination of the pump's flow rate of clean water at room temperature, in the selection of electroplating filter, we need to consider three uncertain factors affecting the actual filtration volume. The specific gravity of the plating solution is greater than the specific gravity of water resistance of the filtration medium to the liquid caused by the loss of flow rate changes in the content of solid impurities in the solution on the loss of flow rate.
