    Analysis of advantages and characteristics of ultrapure water equipment for electroplating

    Electroplating coating ultra pure water equipment mainly uses reverse osmosis technology to produce pure water. The conductivity of pure water made by reverse osmosis membrane can reach below 10us / cm. Because the membrane pore size of the reverse osmosis membrane is very small (filtration accuracy of 0.0001 microns), the desalting rate of the water produced by the system can reach about 99%. Therefore, it can effectively remove dissolved salts, colloids, microorganisms, and organic matter in water (removal rate is as high as 97-98%). Reverse osmosis pure water equipment has the advantages of good water quality, low energy consumption, no pollution, simple technology, and simple operation. At present, it is widely used in industrial ultrapure water production process.
    The ultra-pure water equipment used for electroplating coating can have a resistivity of more than 18 trillion. In the process of electroplating and rinsing in the electroplating industry, the resistivity of water can usually meet the requirements below 15 trillion. The surface of some metal objects or other materials must be sprayed with an anticorrosive coating. At the same time, in order to increase the brightness of the product, ultrapure water needs to be used for cleaning. Electroplating and coating ultrapure water equipment can save energy. , Purified water equipment structure is rigorous.
    Work flow of ultrapure water equipment for electroplating coating There are currently three methods of preparing ultrapure water. The most widely used technology is resin replacement technology, and the second is pure water resistivity, which is not the leading two-stage reverse osmosis technology. Three are the most commonly used RO + EDI combined processes. The raw water enters the pressure pump in the equipment to increase the pressure value of the water. After the raw water passes through various filtering devices, it can remove a large amount of colloids, visible particulate impurities and sediments in the raw water, and it can also adsorb the remaining chlorine in the water. After reaching the host composed of RO and EDI , the impurities of the raw water are further removed. The effluent after this step has already met the relevant standards, and then processed again by the disinfection and sterilization device, and the water quality reaches the best.
    Advantages of ultra-pure water equipment for electroplating coating The ultimate water resistivity of ultra-pure water equipment for electroplating coating can reach 18.2 trillion or more, which can meet the water demand of any industry. There will not be a large number of equipment in the process of preparing pure water. The emergence of wastewater, less operating capital investment, and enhanced reliability.
