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
The invention belongs to course of manufacturing printed circuit board washing water sterilization algae removal technical field, be specifically related to a kind of chemical sterilization algae removal method.
Background technology
In electroplating printed circuit board process, microorganism be take slime bacteria as main, and its metabolism produces a large amount of mucus, and mucus is other suspensions in adsorbed water again, once stick on plate face, will form thread copper ashes or other forms of bad.Generally taking at present manually to return methods such as washing, change pure water solves, the rinsing bowl that RuPCB factory electroplates is all to maintain weekly once to remove a large amount of bacterium secretion of washing cell wall, need artificial scouring again to change water, expend a large amount of time, bring certain pressure to producer's production capacity aspect.But be in cost and efficiency, not to be most economical method.Manually return to wash easily to cause to scrape to injure and sever the bad of circuit and scrap.Changing pure water increases the cost of cost of manufacture and waste water treatment.A lot of circuit board cleaning agents adopt and add oxidizing substance if boric acid, hydrogen peroxide are as Fungicidal substance, but oxidizing substance likely makes copper surface oxidation.For head it off, some Patent Application Publication add the cleaning agent formula of protective substance, as application number 201310523745.1, but formula is comparatively complicated, cost of manufacture is relatively high.
The patent No. 200410012799.2 discloses a kind of sterilizing methods that adds non-oxidative bactericide in printed circuit board (PCB) water-washing process.But non-oxidizable Biocidal algae-killing agent is the non-oxidizable compound of chlorophenols, quaternary ammonium salt normally, the relative oxidisability Biocidal algae-killing agent of its disposal cost is higher, easily causes environmental pollution, and the microorganism in water easily develops immunity to drugs.
Summary of the invention
The object of the present invention is to provide a kind of Biocidal algae-killing agent, be specifically designed to the professional sterilization processing of the washing water of board production and manufacturing, effectively the microorganism such as kill bacteria, fungi.
For achieving the above object, the present invention has adopted following technical proposals: a kind of Biocidal algae-killing agent for the treatment of washing water in course of manufacturing printed circuit board, is characterized in that being made by sodium polysulfide, sodium bicarbonate, acrylic acid formicester, acid amides and surfactant and pure water.
As preferably, described Biocidal algae-killing agent is prepared in following ratio: get by weight percentage the sodium polysulfide of 0.20-0.25%, the sodium bicarbonate of 0.28-0.35%, the acrylic acid formicester of 0.1-0.2%, the acid amides of 0.3-0.35%, the surfactant of 0.01-0.02% and 99% pure water are mixed and make.
As preferably, described surfactant is dodecane and benzene sulfonic acid sodium salt or quaternary surfactant.
A method for washing water sterilization algae removal in course of manufacturing printed circuit board, is characterized in that preparing above-mentioned Biocidal algae-killing agent, adopts automatic flow controller to add continuously described Biocidal algae-killing agent in washing water, and general dosage is 200-300ppm.Surfactant is as the carrier with identification cell membrane function, and sodium polysulfide and sodium bicarbonate to cell membrane, and then stop Growth of Cells metabolism with bacteria growing inhibiting with SURFACTANT ADSORPTION.
The invention has the beneficial effects as follows: by adding described Biocidal algae-killing agent to carry out chemical sterilization algae removal in course of manufacturing printed circuit board washing water, do not affect production output and product quality, can solve due to bacteria growth problems a large amount of in quantity-produced process, part operation can adopt overflow washing, this can make on the basis of normal Water usage, to reduce by 1/3rd to 2/3rds water consumption in printed circuit board (PCB) manufacture, has well solved the environmental protection pressure of producer.Effectively reduce comprehensive production cost, improve speed and the quality, particularly a first-pass yield of producing.Described Biocidal algae-killing agent is non-oxidizing, it is not to realize effective sterilization by destroying cell membrane, but sterilization component is attached to the carrying out that stops Growth of Cells metabolism on the carrier with identification cell membrane function by effective combination, can not produce drug resistance problem, there is good bactericidal effect, the function under certain concentration with quick sterilization, one time killing rate approaches 100%.Described Biocidal algae-killing agent not can with existing all liquid medicine generation bad reactions such as plating, can not cause any compatibility problem to any processing procedure of PCB.
