The invention is widely used in various manufacturing industries such as agriculture and animal husbandry, industry, high technology, transportation, electronic equipment and their daily life products, and it is the scientific research and processing process that this product is widely used. The cause of the electroplating process not only makes the metal material not easy to leach, makes the plastic products more durable, and makes the surface of such crafts more beautiful and generous, but also because of this excellent performance of the electroplating process goods, people around know that the electroplating process goods are very common.
Everyone realizes that a good plating process goods should have a smooth, glossy surface, a well-proportioned surface, and be applied without fading, rusting, or falling off easily. Thus, to improve the characteristics and the level of beauty and generosity of the plating products, some preservatives are often added to enhance the luster and gloss of the goods when the plating process is carried out. For example, in hot-dip galvanized products, often use blue zinc passivator, color zinc passivator, gray-black passivator, etc. The effectiveness of hot-dip galvanizing passivator is, to put it bluntly, to make the goods less likely to be effective with the co2 in the gas, with the actual effect of blocking air oxidation.
Add blue zinc passivate to make the plating parts deeper and brighter, at the same time, also make the plating products brighter and more uniform, improve the grade of goods, perhaps for the purpose of enhancing the solidity and corrosion resistance of the plating wafer is also necessary to improve the impact resistance of the product, and also play a role. Color zinc passivation, can improve the smoothness of the hot-dip galvanized layer, improve the corrosion resistance of goods, not easy to flower, not easy to fade, and in the hot-dip galvanized parts of the color feel more vivid. Gray-black passivation refers to the production of a layer of gray-black original film produced on the surface of the finished product, the appearance of goods look more imposing.
Perhaps this plating additive is too high for the actual operation. The temperature, concentration value and PH of the aqueous solution are all harmful to the actual effect of the plating process, and must be adjusted frequently during operation and strictly enforce safety procedures. There are two main categories of preservatives in electroplating plants, one is organic chemical preservatives (e.g. coumarin for nickel plating) and the other is inorganic preservatives (e.g. cadmium salt for barrel plating).
Most of the plating additives used are inorganic salts, which later gradually dominate the plating additives. According to the classification of the role of plating additives, they can be classified as leveling agents, brightening agents, wetting agents, stress relievers, etc. Preservatives with different roles usually have different structural characteristics and efficacy principles, but smart preservatives are also common, for example, saccharin can be used as a nickel plating brightener or as a general agent for stress relief; and preservatives with different roles follow the same efficacy principles.
