powder. Soluble in acid, insoluble in water. It can be complexed with potassium pyrophosphate to form a water-soluble copper potassium pyrophosphate complex. Pyrophosphate copper plating is a widely used electroplating copper process used in electroplating plants. The characteristic of the process is that the plating solution is relatively stable, the plating layer is finer, the dispersing ability and the covering ability are better than the acid copper plating, the cathode current efficiency is higher than the cyanide copper plating, and a thick coating layer can be obtained, and no irritating gas is obtained during the electroplating process. Escaped, so the ventilation equipment can be omitted, the plating solution is non-toxic, and it has no corrosion to the equipment, and is especially suitable for electroplating of printed circuits and zinc alloy die-casting parts.

Industrial grade Potassium pyrophosphate 7320-34-5 (K4O7P2) uses Price

Potassium pyrophosphate, also known as tetrapotassium pyrophosphate, is produced by the melting of potassium dihydrogen phosphate to lose water molecules. It is a white crystalline powder or granule at room temperature. It has strong hygroscopicity in air and is highly soluble in water. However, it is insoluble in ethanol, and the aqueous solution is alkaline, which inhibits food spoilage and fermentation. It is often used in combination with other condensed phosphates. In order to make the plating layer smooth and firm, the formulation of the plating solution in industrial production is often complicated. In the past, cyanide was commonly used as a complexing agent to prepare a plating solution. However, due to the high toxicity of CN-, the health of electroplating workers is greatly damaged. At the same time, the discharge of sewage and exhaust gas containing CN- also seriously pollutes the environment. Therefore, electroplating is now mainly used for cyanide-free plating, and this complexing agent for r

Stannous chloride, chemical formula SnCl2. It is a white or white monoclinic crystal. The relative density is 2.710, the melting point is 37.7 degrees, and it is decomposed into hydrochloric acid and a basic salt at the melting point. The anhydrous has a density of 3.950g/cm3 and a boiling point of 623°C. It decomposes into hydrochloric acid and basic salt at the melting point, and is easily soluble in water, alcohol and glacial acetic acid. The solubility in concentrated hydrochloric acid is greatly increased, and one water can be used. The form of matter and tetrahydrate exists.
