During the anodizing process, part of the electrical energy will be converted into heat energy. As the bath temperature increases, the quality and metal loss of the film are significantly reduced, and the outer layer of the film has a low hardness. Under atmospheric conditions, this film will appear "pulverized". Therefore, it is very important to control the temperature of the oxidation tank. Generally controlled between 18℃-22℃.
Oxidation tank refrigeration types are generally divided into three types
l? First, direct cooling: one oxidation tank corresponds to a freezer, and an acid-alkali resistant pump is used to directly cool the sulfuric acid oxidation solution. It is pumped into the ice water machine, cooled in the acid and alkali resistant SS316L exchanger, and then returned to the oxidation tank. This method cools quickly. One-to-one correspondence, the oxidation tanks will not affect each other's operations.
l? Second, indirect cooling: a set of temperature control tanks are specially designed. This temperature control tank implements heating tubes and cooling, and the temperature can be set as needed. There are 1-2 ice water machines for temperature management. Each group of oxidation tanks corresponds to a plate exchanger. The plate exchanger has an inlet and outlet for ice water and liquid medicine to implement the temperature control of each group of oxidation tanks. This method saves energy. In summer, the ice water machine needs to be turned on at full load. In winter, the ice water machine needs to be turned on at full load. The ice water machine is half turned on.
l? Third, direct mixed flow type: a set of management tanks are specially designed. This management tank can perform functions such as chemical addition, heating and cooling. Each group of oxidation tanks overflows to the corresponding management tank through circulation. When passing through the ice water machine (or heating pipe), the temperature of the management tank is controlled between 18°C ??and 22°C. Advantages of this method: The temperature of several oxidation tanks is guaranteed to be consistent.
Based on the ingredients of the potion, there are two types of heating designs: electric heating and steam heating.
For electric heating tubes, our company adopts brands with reliable quality. The quartz tube is guaranteed for half a year. The stainless steel and TEFLON heating tubes are guaranteed for one year, and are designed to be heated to process temperature within 3 hours.

7. Open program (software) 7.1 The oxidation line crane control programs are all intelligent and fully open programs. After the on-site supervisor inputs the password for process and working time operations, it can be automatically implemented according to production needs and environmental changes. Revise. 7.2 Multiple material numbers can also be mixed for production. There is no need for professional programming engineers to draw ladder diagrams and then enter DM codes, which greatly improves work efficiency.
8.DMS data monitoring system (optional item) 8.1 The computer monitoring system can monitor the working status of the production line crane. The electroplating process parameters can be monitored and modified, including the rectifier current setting record, the working temperature setting record in the tank (setting records are automatically added), and the processing time of each tank can be monitored, and high and low water level abnormality alarms can be monitored.
8.2 The computer collects, displays, records and saves relevant operating process parameters and data, and prints them out in the form of production reports, so that managers can have a good grasp of the production status of the equipment.
8.3 When an equipment failure occurs, the alarm device will sound an alarm and display the corresponding fault code. The operator will promptly troubleshoot the fault according to the code instructions, and the computer will also record the time of occurrence and repair time. And can print or make reports.
8.4 The DMS system sets the permission to enter the operation. The operator can modify the parameters after entering with the password.
8.5 It can be connected to the Internet to remotely monitor all production data, which also facilitates the management of the entire enterprise.
