For example, if the indirect cooling method is used to lay heat exchange tubes inside the electroplating tank, and chilled water flows through the heat exchange tubes, then in this case, a standard coil evaporator structure and a standard chiller will suffice.
If the direct cooling method is used, there is no heat exchange tube in the electroplating tank, and the liquid entering the electroplating oxidation chiller is an acid-base solution, then the evaporator material of the electroplating oxidation chiller needs to be made of 316 stainless steel or titanium, and the structure is a closed shell tube.
In addition, the water pump needs to be equipped with a PP material that is an anti-corrosion plastic water pump. If the acid-base solution is directly cooled, the acid-base ratio is about 20%-25%.
But note: chemical materials such as oxalic acid, OP emulsifier, hydrogen peroxide, etc. are strictly prohibited in sulfuric acid. Otherwise, the stainless steel will react chemically to corrode the stainless steel.
The use temperature should not exceed 40°C, otherwise it will destroy the passivation film formed by stainless steel and cause corrosion.
Summary of the selected structure: the oxidation tank of the heat exchanger adopts a standard chiller (coil evaporator). The aluminum oxidation tank without heat exchange tubes adopts an electroplating oxidation chiller (the evaporator structure is shell and tube, and the material is corrosion-resistant).
The special chiller plays a very important role in the production and processing of electroplating oxidation equipment. It can ensure the stability of the process and the consistency of product quality, and plays an irreplaceable role in the processing. Therefore, when choosing a special chiller, it is necessary to choose the appropriate model and cooling capacity according to the actual needs, and choose a brand with high performance and quality to ensure the normal production and processing.
If the temperature of the electrolyte is out of control during electroplating oxidation, the quality of electroplating will be poor, and it will seriously cause problems in large quantities of products. Then the special electroplating oxidation chiller can effectively solve this problem.
Electroplating oxidation equipment is a technology often used in modern production and processing processes, and the normal operation of such processes requires a certain constant temperature. In order to achieve this goal, Jiusheng chiller is widely used in the production and processing of electroplating oxidation equipment to control the temperature and humidity of the process.
The price of a dedicated chiller varies depending on the model, cooling capacity and manufacturer.
Generally speaking, the price of an electroplating oxidation chiller ranges from thousands of yuan to hundreds of thousands of yuan, and the specific price will vary depending on factors such as model, brand, cooling capacity, and main materials for appearance. The lower-priced special-purpose chillers are mostly used in small-scale production and processing plants, while the higher-priced special-purpose chillers are mostly used in large-scale production and processing plants and processing plants that have extremely high requirements for temperature and precision. When choosing, you should choose according to your own needs and economic budget. Such customized services can meet the specific production and processing needs of customers, and also help to improve the performance of the special chiller for electroplating oxidation equipment.
When purchasing a special chiller for electroplating oxidation equipment, factors such as the actual production and processing needs, the temperature and humidity requirements of the process, the performance and quality of the machine need to be considered. Jiusheng chiller can be widely used in electroplating oxidation oxygen machine oxidation, optical coating, micro-arc oxidation surface treatment process, can provide effective cooling for rectifier cabinets and rectifiers, and improve the service life of equipment.
At the same time, the convenience and cost of maintenance and maintenance, as well as the after-sales service provided by the manufacturer, should also be considered when purchasing a special chiller. These factors will affect the service life and maintenance cost of the chiller, so they need to be fully considered before purchasing. Only by selecting a suitable special chiller can the normal operation of the electroplating oxidation equipment and the stability of product quality be guaranteed.
