Problems solved by technology
However, non-oxidative bactericides and algicides are usually non-oxidative compounds such as chlorophenols and quaternary ammonium salts, and their treatment costs are higher than those of oxidative bactericides.

The invention provides a PCB water bactericide which is characterized by being prepared from sodium polysulfide, sodium bicarbonate, methacrylate, amide, a surfactant and purified water. The PCB water bactericide has a good sterilization effect and has a rapid sterilization function under a certain concentration, the one-time killing rate is close to 100 percent, and the amount of washing water can be reduced by 1 / 3 to 2 / 3.
Description
technical field [0001] The invention belongs to the technical field of washing water sterilization and algae removal in the manufacturing process of printed circuit boards, and in particular relates to a chemical method for sterilization and algae removal. Background technique [0002] During the electroplating process of printed circuit boards, the microorganisms are mainly slime bacteria, and their metabolism produces a large amount of mucus, which absorbs other suspended substances in the water. . At present, it is generally solved by manual backwashing and pure water replacement. For example, the washing tanks electroplated in PCB factories are maintained once a week to remove a large amount of bacterial secretions on the walls of the washing tanks. Manual scrubbing is required to replace the water, which consumes a lot of time. Bring some pressure on the production capacity of manufacturers. But it is not the most economical method in terms of cost and efficiency. Ma...
