21.What is electrolysis? Answer:When the electric current passes through the electrolyte, the redox reaction occurs on the electrode so that the electrolyte is decomposed under the action of the current is called electrolysis. When the electrolyte is energized, the cations move to the cathode, and get electrons at the cathode and be reduced to a new substance; anions move to the anode, and lose electrons at the anode and be oxidized to a new substance. Sometimes the oxidation of the electrode material also occurs at the anode. An example is the electrolysis of molten sodium chloride.NaCl→Na++Cl-Cathode Na++e→NaAnode 2Cl–2e→Cl2↑Electrolysis industry plays a huge role in the national economy, the smelting of many non-ferrous and rare metals, the preparation of chemical industry products and electroplating, electropolishing, anodic oxidation and so on are realized by electrolysis. Translated with DeepL.com (free version) 22.What is electroplating? Answer: By electrolysis, in the metal parts on the surface of the deposition of a thin layer of other metal methods, it is called electroplating. Plating includes pre-plating treatment (oil removal, rust removal), plated metal layer and post-plating treatment (passivation, dehydrogenation) and other processes. It is used to prevent corrosion of metal products, repair worn parts, increase durability, reflectivity, electrical conductivity and aesthetics. Plating will be metal parts as the cathode, the plated metal plate or bar as the anode, respectively, hanging in the copper pole bar above the electrolyte containing plating components immersed in the direct current.In individual cases, there are also insoluble anodes, such as chromium plating with lead or lead-antimony alloy anode. 23.What is current strength? Answer:Current strength, referred to as current, is the amount of electricity passing through the cross-section of the conductor per unit time. The unit is ampere, referred to as ampere (A). 24.What is the current density? How to calculate? Answer:Current density…

Brand tag temperature of electrophoresis rack

2025-04-23

The term “Brand tag electrophoresis lattice” is not a common term in the industry, but in conjunction with the “electrophoresis lattice” related process, the temperature control needs to be determined according to the specific type of process and equipment requirements. The following is the possible temperature range and analysis: Electrophoresis process temperature Conventional electrophoresis We controll the temperature of the electrophoresis bath at 25°C to 30°C to make sure a uniform and dense electrophoresis film. Too high a temperature may cause the paint film to hang, and too low a temperature may affect the reaction rate of electrophoresis. Low temperature electrophoresis For some special processes ( low-temperature curing electrophoresis paint),we should control the bath temperature at 15°C to 20°C to match the low-temperature curing system. Curing temperature of the frame (coating) Heat curing If “lattice” refers to the curing of the coating after electrophoresis, the temperature is usually 160°C to 180°C and the time is 20 to 30 minutes, depending on the type of electrophoresis paint ( epoxy, polyester). UV curing We use UV curing to instantly cure coatings without heat, relying on a UV light source instead Equipment operating temperature Electrophoresis tank We should equip with a temperature control system in tank to ensure that the temperature of the tank liquid is stabilized within the range of process requirements, with a fluctuation of no more than ±2°C. Curing equipment The temperature of curing oven should be uniform, and the temperature difference should not exceed ±5°C to avoid uneven coating quality. Special process temperature Low temperature electrophoresis + high temperature curing Some processes may use low-temperature electrophoresis with high-temperature curing , and the temperature control of the electrophoresis and curing stages should be strictly differentiated. Rapid curing Some high solids electrophoresis paints may support low temperature rapid curing from 140°C…
