Many people will ask is chrome-plated self-spraying paint toxic? In fact, the metal chrome on the surface of chrome-plated parts is harmless. During the electroplating production process, chrome-plated products will be washed many times, and the amount of chrome salts left on the product parts is actually very high. Less. Chrome-plated spray paint, commonly known as electroplating, has better effect than ordinary spray paint, good color, and maintains brightness for a long time, while ordinary spray paint is easy to scratch and fall off, not as good as chrome-plated self-spray paint.
Chromium metal has few harmful effects on the human body, and there are no reports of industrial poisoning caused by it. Chromium entering the human body accumulates in human tissues, is metabolized and eliminated at a slower rate. Chromium metal in acid is usually characterized by surface passivation , Once the passivation is removed, it is easily soluble in almost all inorganic acids, but insoluble in nitric acid. Chromium is soluble in sulfuric acid, but not in nitric acid.
The most harmful to the human body is electroplating chromium, especially hexavalent chromium. Hexavalent chromium is easily digested and absorbed by the human body. According to digestion and absorption, respiratory system, skin and mucous membranes, it can invade the human body. According to different concentrations of chromium in the inhaled air It can also cause nasal septum perforation and bronchiectasis when the condition is severe. Invasion of the digestive system can cause vomiting and abdominal pain. When it invades the skin, it can cause dermatitis and eczema. Greater harm risk of long-term or short-term exposure or inhalation of carcinogens.
After all, chrome-plating self-spraying is a painting process, so the adhesion is definitely not as strong as that of chrome-plating on metal surfaces. As long as it is not compared with the effect of chrome-plating on metal surfaces, the process is acceptable. So we don’t have to worry about using chrome-plating self-spraying paint on itself. cause harm.
