Electronics Industry Sector
Semiconductor Manufacturing: In the production of semiconductor chips, almost every step requires highly purified water. From wafer cleaning to processes like lithography and etching, the water must be virtually free of impurities. The ultra-pure water produced by EDI systems (with resistivity exceeding 18.2MΩ?cm) effectively prevents ions, organics, and microorganisms from affecting the chip manufacturing process, ensuring the performance and quality of the chips. For instance, during lithography, even minute particles of impurities can lead to defects in the chip's circuitry. EDI pure water provides a clean rinsing medium for photoresist, guaranteeing the accuracy of the chip's pattern.
In the manufacturing of electronic components such as capacitors, resistors, and transistors, high-quality pure water is also required. In processes like electroplating and cleaning, EDI pure water prevents impurity ions from depositing on the surface of components, thereby enhancing their electrical performance and stability. For instance, using EDI pure water for cleaning boards in capacitor production can avoid impurity ions affecting the capacitance value and tangent of loss angle of capacitors.
Printed Circuit Board Manufacturing: During the production process, printed circuit boards require multiple cleanings to remove impurities generated from drilling and etching. EDI pure water effectively removes metal ions and particulates from the board's surface, ensuring optimal conductivity and insulation. For instance, in the final cleaning stage of the circuit boards, using EDI pure water prevents residual impurities from causing short circuits or other electrical faults.
Chemical Industry
In the synthesis of chemical raw materials, many reactions must be conducted in a pure water environment to ensure the accuracy of the reactions and the quality of the products. EDI pure water provides a reaction medium free of impurity ions, avoiding interference from impurities in the chemical reactions. For instance, when producing high-purity chemical reagents, such as analytical reagents and premium reagents, EDI pure water is an essential raw material, used in processes like dissolution, crystallization, and purification of the reagents.
In the manufacturing of fine chemical products, such as cosmetics, fragrances, and coatings, the purity of water directly impacts the quality and stability of the products. EDI pure water is used in formulation, emulsification, and dilution processes to ensure the optimal color, texture, and performance of the products. For instance, in the production of cosmetics, using EDI pure water can prevent chemical reactions between metal ions in the water and active ingredients in the cosmetics, extending the shelf life and enhancing safety.
Lab Application
Biological Laboratory: In biological experiments, such as cell culture, genetic engineering, and protein purification, sterile and pyrogen-free pure water is required. EDI pure water equipment can provide high-quality water that meets the requirements of biological experiments, creating a favorable environment for cell growth and preventing contamination from microorganisms and impurities in the experimental samples. For instance, during the cell culture process, EDI pure water is used to prepare culture media and clean cell culture vessels, ensuring the normal growth of cells and the smooth progress of the experiment.
Electric Power Industry
Boiler Feed Water: During the process of thermal power generation, boilers require a substantial amount of feed water. High-purity water produced by EDI (Electrodeionization) systems can serve as boiler feed water, effectively preventing scaling and corrosion within the boiler. Hardness ions like calcium and magnesium in the water can form scale on the boiler's heat transfer surfaces, reducing efficiency and potentially causing damage to boiler piping. EDI pure water is nearly free of hardness ions, thus extending the boiler's lifespan and enhancing power generation efficiency.
Nuclear Power Plant Cooling System: The cooling system of nuclear power plants has strict water quality requirements, necessitating the use of high-purity water to ensure optimal cooling efficiency and equipment safety. EDI pure water supplies cooling water free of impurities and radioactive substances, preventing damage to critical equipment like the nuclear reactor during the cooling process. For instance, in a nuclear reactor's primary cooling system, EDI pure water serves as the cooling medium, effectively removing heat generated by the reactor while avoiding the risks of impurities causing radioactive leaks and other safety incidents.
