We want to determine the cooling capacity of the chiller must be greater than the amount of heat produced in the plating process, so that the solution can be cooled. And we know that, the electroplating bath solution is sulfuric acid solution, to prevent corrosion of the refrigeration equipment is to in the electroplating bath with corrosion resistant heat exchange coil, cold water machine out of the chilled water into the corrosion resistant heat exchange coil, directly with the inner groove of acid liquid for heat exchange, take away heat of solution tank cooling. If in the plating bath casual clothes are not design corrosion resistant heat exchange coil, outside the groove arranged is provided with a resistance to corrosion of the water heat exchanger, side walk chilled water walking acid plating liquid.
If the acid liquid directly into the cold water machine, the direct cooling method, the heat exchanger inside the cold water heater must be made of corrosion-resistant materials, its cost is higher than the general cold water machine. So in understanding of the advantages and disadvantages, we should according to the actual situation to determine the need for cooling, and then choose the chiller.
The role of electroplating cold water machine:
Electroplating production and processing technology, electroplating bath solution continuously produce heat build-up, solution temperature increased gradually, when the solution tank temperature high technological requirements, for the production of electroplating products surface coating fastness, uniformity and flatness and surface smooth degree has a greater impact. Therefore, it is required to use the chilled water cooler to cool the solution in the bath and keep the temperature of the solution in the plating bath to be constant.
