  • Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank. Zinc is a silver-white metal, brittle at room temperature, soluble in acid and alkali, known as amphoteric metal. Pure zinc is more stable in dry air. In humid air or small water containing carbon dioxide and oxygen, the surface of large rolls of galvanized wire will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer.
