The accumulation of organic impurities caused by decomposition products and the pollution of some other metal impurities. There is no turnover of long-term stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe to avoid price difference. The price is % higher than the market price! The price of more than one ton is higher! So that the nickel bath can not get the ideal bright nickel coating, it is necessary to carry out large-scale treatment. In the solution of bright nickel plating on stainless steel pipe the brightener has developed rapidly and has many varieties. To sum up, the development of brighteners has experienced four generations. Instead of the original product saccharin and butynediol can be plated with bright nickel with high flatness. Its application flourished in the s and s. It seems that due to the instability of butynediol in the nickel plating bath, short service life and rapid accumulation of organic impurities, the nickel bath needs to be treated frequently. Therefore, epoxy chloropropyl or epoxy is branched with butynediol to synthesize the second-generation nickel plating brightener, such as b brightener. The situation has improved. Be and retain alkynyl. Later, pyridinyl is polymerized to form the third-generation product, Faster light output, less amount of brightener and longer service life. Now it further uses various combinations of nickel plating brightener intermediates to form a new brightener, which has developed to the fourth generation of products. It has less use, faster light output speed and longer treatment cycle. According to the connection and rolling process, stainless steel pipes with deep plating capacity mainly include hot-rolled, hot-rolled and cold drawn (rolled) stainless steel pipes.
