Skin hazards caused large electroplating industry

Electroplating is inseparable from the industrial production of the main job, and most metal workpiece must be polished before plating, mechanical polishing, etc., these operations will generate a lot of the process may contain silicon, chromium, aluminum, iron, copper and linen such as dust. Dermatology Hospital of Guangzhou General Hospital of Guangzhou Air Force) of the experts pointed out that, in addition to metal dust outside the human body has a deep against the skin and severe tissue damage. Dust contains a variety of harmful ingredients not only corrosive to the skin, but also makes the skin tissue rupture, bleeding, occurrence of various skin diseases, severe cases can lead to skin cancer.
Electroplating production crises produce skin need to be cautious
Electroplating production to extensive use of acids, alkalis, salts and organic solvents and other chemicals, in the work process will emit large amounts of toxic gases, such as security Molybdenum plate work done well, prone to poisoning, burns, causing skin swelling, bleeding, skin tissue rupture. On the other hand, wet electroplating workshop workplaces, equipment susceptible to corrosion, but also easily lead to electric shock. Skin diseases caused by electroplating production in crisis, people need to take special care, strengthen the prevention and tungsten carbide inserts of skin diseases is crucial.galvanized after passivation film, white and color passivation passivation layer that kind of good corrosion resistance?
A: galvanized after passivation film, color than white passivation passivation good corrosion resistance. This is because the treatment for blunt white is the color of the passivation film has been formed in the bleaching solution, dissolve treated layer, a passivation film of the color white. Since the white color passivation layer over the passivation layer is thin, the corrosion resistance can be reduced.
