Hazards of illegal electroplating

Date of issue: 2019-09-21 Author: Click:

illegal Electroplating equipment manufacturer Due to the imperfect pollution treatment mechanism, production has caused great harm to the environment and the health of the surrounding people:




First, air pollution: strong acids, alkalis, salts, organic solvents and other chemicals should be used in large quantities in electroplating production, which will emit a large number of toxic and harmful gases in the process of operation. For example, hydrofluoric acid smokes in the air, and the steam has very strong corrosivity and toxicity; When electroplating chromium, a large amount of chromium mist will be emitted. Chromium compounds can cause skin ulcers, anemia, nephritis, neuritis and other diseases, and have the effect of carcinogenesis and inducing gene mutation.






The second is water resource pollution: the main source of zinc in electroplating and metal processing wastewater is electroplating or pickling drag solution. The pollutants are transferred to the rinsing water through the metal rinsing process. The pickling process includes first immersing the metal (zinc or copper) in strong acid to remove the oxide on the surface, and then immersing it in the brightener containing strong chromic acid for polishing. The wastewater contains a large amount of hydrochloric acid, zinc, copper and other heavy metal ions and organic brighteners, which are highly toxic. Some of them also contain carcinogenic, teratogenic and mutagenic highly toxic substances, which are extremely harmful to human beings.

Third, dust hazard: most hardware parts must be polished and mechanically polished before electroplating; In addition, in order to remove the slag, molding sand, oxide skin and other impurities on the surface of castings, forgings or heat treated parts, sandblasting is also required. These operations will produce a large number of dust that may contain silicon, chromium, aluminum, iron, copper and linen.

Fourth, there is an explosion risk: organic solvents are often used to degrease and degrease workpieces in electroplating production. Common organic solvents include gasoline, kerosene, acetone, benzene, trichloroethylene and carbon tetrachloride; In addition, paint remover is used to remove the old coating and varnish (sealing) paint is used to seal the coating. The paint remover contains a large amount of dichloromethane and other organic solvents, and varnish (sealing) paint also contains a variety of organic solvents. Gasoline, kerosene, benzene and other organic solvents have low flash points and are volatile in the air, When the mixture of vapor and air reaches the lower explosion limit, fire and explosion accidents will occur in case of spark and other ignition sources.
