Ultrapure water Tips: ultrapure water refers to the following low impurity content of water: - EDI EDI ultra-pure water equipment ① inorganic ionized impurity Guangzhou ultra-pure water equipment purchases, such as Ca, Mg, Na, K, Fe, Fe , Mn, Al, HCO Yin, CO Yin, SO Yi, Cl, NO entertainment, NO Yin, SiO Yin, PO etc; ② organic compounds, such as benzene sulfonic acid, oil, organic iron, organic aluminum and other hydrocarbons etc; EDI ③ ultra-pure water equipment factory Guangzhou particles, such as dust, iron, aluminum, colloidal silica, etc; ③ microorganisms, such as bacteria, plankton and algae; ⑤ dissolved gases, such as N2, O2, CO2, H2S, etc. Resistivity values ??of water content in ultrapure water to measure ionized impurity. In theory, pure water only H ions and OH ions participate conductive. When ultrapure water at 25 ℃ resistivity of 18.3 (megohm-cm), typically about 15 to 18 (megohm-cm). Determination of organic content in ultrapure water from the organic carbon content, depending on the provisions of the electronics industry ultrapure water content of 50 to 200 micrograms / liter Guangzhou EDI ultra-pure water equipment, and requires a diameter larger than 1 micron particulate matter per 1 ml within amount of 1 to 2 EDI ultra-pure water equipment wholesale Guangzhou, microbes per 1 ml of 0 to 10. Modern use of pretreatment, electrodialysis, ultraviolet disinfection, reverse osmosis, ion exchange, ultrafiltration and various membrane filtration techniques, so that the resistivity of ultra-pure water reached 18 (megohm-cm) at 25 ℃. - EDI Applications EDI ultra-pure water equipment, ultra-pure water equipment, ultra-pure water is often used in the microelectronics industry, the semiconductor industry, power industry, the pharmaceutical industry and laboratories. EDI water can be used as pharmaceutical distilled water, boiler feed water, food and beverage production water, power plants, as well as ultra-pure water for other purposes. EDI ultra-pure water equipment is more advanced in the current international reverse osmosis desalination technology to prepare deionized water preparation technology is a purely physical process. EDI ultra-pure water equipment application areas: 1, the production of aluminum electrolytic capacitors and cleaning the workpiece; 2, sub-tube production, of a cathode coated with liquid carbonate; 3, tubes and cathode ray tube production, ingredients with pure water; 4, black and white CRT screen production, glass cleaning, sedimentation, moist, washing the membrane, neck washed with pure water; 5, the production, the need to use a liquid crystal display screen and with pure water cleaning with liquid; 6, transistor production mainly used to clean silicon wafers, while a small amount of liquid used in the preparation; 7, the integrated circuit wafer manufacturing high pure water; 8, semiconductor materials, devices, printed circuit boards and integrated circuits; 9, LCD liquid crystal display, PDP plasma display panel; 10, high-quality tubes, fluorescent powder production; 11, a semiconductor material, wafer material production, processing, cleaning; 12, ultra-pure materials and ultra-pure chemical reagents, ultrapure chemical materials; 13, laboratory and pilot plant; 14, automotive, appliance surface polished; 15, optical products, other high-tech microscopic products.
