Compared with other industrial production, electronic tube production has many unique properties.
(1) Covering a wide range of technologies 1. Vacuum technology 2. Glass technology 3. Mechanical Technology 4. Chemical Technology 5, Radio Technology 6, Metallurgical Technology (2) Various kinds of materials 1. Metal materials: tungsten, molybdenum, copper, nickel, iron, mercury, zirconium and titanium, as well as tungsten-molybdenum, nickel-manganese, chromium-copper, Iron-Nickel-Cobalt alloys, and nickel-plated, gold-coated, silver-coated, zirconium-sprayed, titanium-sprayed, carbon-sprayed process composite materials. 2. Chemical materials: alcohol, butyl acetate, caustic sodium, barium nitrate, acetone, nitrocotton, etc. 3. Insulation materials: mica, ceramics, bakelite, quartz and glass, etc. 4. Industrial gases: hydrogen, oxygen, nitrogen, natural gas, steam, purifying compressed air, etc. (3) Good vacuum environment High cleanliness is the most important condition to ensure the quality of electronic tubes. Especially in cathode manufacturing and rack room, dust-proof level is higher. Employees must strictly abide by the vacuum hygiene system, such as washing hands, changing clothes, changing shoes, wearing hats, etc.
