The invention provides a sterilizing and alga killing agent for treating washing water generated in a printed circuit board manufacturing process. The sterilizing and alga killing agent is characterized by being prepared from sodium polysulfide, sodium bicarbonate, methacrylate, amide, a surfactant and pure water. The sterilizing and alga killing agent has a favorable sterilizing effect and has a rapid sterilizing function at a certain concentration, and the single-time killing rate is approximate to 100%; and the dosage of the 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...
