Application scope of pure water equipment in water treatment

Release date: November 27, 2019 11:33:43

In the production of electric capacitors, pure water is needed for cleaning aluminum foil and working parts. If the water contains chloride ions, the capacitor will leak electricity. In the production of electron tube, if impurities are mixed into the cathode of electron tube, the emission of electron will be affected, and then the amplification performance and life of electron tube will be affected. Therefore, pure water should be used for the solution preparation. In the production of picture tube and cathode-ray tube, a layer of fluorescent substance is attached to the inner wall of the fluorescent screen by spraying or precipitation method, which is composed of zinc or other metal sulfide The light powder particles are bonded with potassium silicate, and the preparation needs pure water. If the copper content in the pure water is more than 8ppb, it will cause light discoloration; if the iron content is more than 50ppb, it will change color, darken and flash; if it contains colloid, particles, bacteria, etc., it will reduce the intensity of the fluorescent layer and its adhesion with the glass shell, and cause bubbles, streaks, light leakage points and other waste products. In the 12 processes of the production of black-and-white picture tube fluorescent screen, pure water is required for 5 processes, including glass shell cleaning, precipitation, wetting, film washing and tube neck cleaning, and 80 kg of pure water is required for each transistor production [1]. The LCD screen needs to be cleaned with pure water and mixed with pure water. If there are metal ions, microorganisms, particles and other impurities in pure water, the LCD circuit will fail, affect the quality of LCD screen and lead to waste.

The water quality of electronic components and water quality is becoming more and more important in the production of electronic components. In the production of electronic components, high-purity water is mainly used as cleaning water and preparing various solutions and slurry. The use of pure water in the production of different electronic components and the requirements for water quality are also different.
