Abstract
The present invention provides a kind of Biocidal algae-killing agents for handling washing water in course of manufacturing printed circuit board, it is characterized in that being made of sodium polysulfide, sodium bicarbonate, methacrylate, amide and surfactant and pure water, it has good bactericidal effect, has the function of quick sterilization under certain concentration, a killing rate is close to 100%；The washing water consumption of one third to 2/3rds can be reduced.
Description
Technical field
The invention belongs to course of manufacturing printed circuit board washing water sterilization algae removal technical fields, and in particular to a kind of chemistry kills
Bacterium algae removal method.
Background technology
During electroplating printed circuit board, for microorganism based on slime bacteria, metabolism generates a large amount of mucus, mucus
Other suspended matters in water are adsorbed again, once the bad of Filamentous copper ashes or other forms will be formed by being adhered in plate face.At present
General that artificial return is taken the methods of to wash, change pure water solution, the rinsing bowl as PCB factories are electroplated is maintained weekly once to go to remove water
A large amount of bacterial secretory objects of washing trough wall need manually scouring to re-replace water, take a substantial amount of time, and give producer's production capacity aspect band
Carry out certain pressure.But either it is not most economical method in cost and efficiency.It manually returns to wash to easily cause to scrape to injure and sever
It circuit bad and scraps.It changes pure water and then increases cost of manufacture and the cost of sewage disposal.Many circuit board cleaning agents, which use, to be added
Add oxidizing substance such as boric acid, hydrogen peroxide as Fungicidal substance, but oxidizing substance is there is a possibility that copper surface oxidation.To solve
This problem, some patent applications disclose the cleaning agent formula of addition protective substance, such as application number 201310523745.1, but
It is that formula is complex, cost of manufacture is relatively high.
The patent No. 200410012799.2 discloses one kind and adding Non-oxidized sterilization in printed circuit board water-washing process
The sterilizing methods of agent.But non-oxydizing sterilization algicide is typically the non-oxidizing compound of chlorophenols, quaternary ammonium salt,
Processing cost is higher with respect to oxydixing sterilization algicide, easily causes environmental pollution, and the microorganism in water is also easy to produce drug resistance.
Invention content
The purpose of the present invention is to provide a kind of Biocidal algae-killing agents, dedicated for the washing of board production and manufacturing
The professional sterilization processing of water can effectively kill the microorganisms such as bacterium, fungi.
To achieve the above object, present invention employs following technical proposals：One kind was manufactured for handling printed circuit board
The Biocidal algae-killing agent of washing water in journey, it is characterized in that by sodium polysulfide, sodium bicarbonate, methacrylate, amide and surface-active
Agent and pure water are made.
Preferably, the Biocidal algae-killing agent is prepared in following ratios：More sulphur of 0.20-0.25% are taken by weight percentage
Change sodium, the sodium bicarbonate of 0.28-0.35%, the methacrylate of 0.1-0.2%, the amide of 0.3-0.35%, 0.01-0.02%'s
Surfactant and 99% pure water are mixed and are made.
Preferably, the surfactant is dodecane and benzene sulfonic acid sodium salt or quaternary surfactant.
A method of the washing water sterilization algae removal in course of manufacturing printed circuit board goes out it is characterized in that preparing above-mentioned sterilization
Algae agent continuously adds the Biocidal algae-killing agent into washing water using automatic flow controller, and general dosage is 200-
300ppm.Surfactant is as the carrier with identification cell membrane function, and sodium polysulfide and sodium bicarbonate are with surfactant
It is adsorbed onto on cell membrane, and then cell growth is prevented to be metabolized to inhibit bacterial growth.
The beneficial effects of the invention are as follows：By the way that the Biocidal algae-killing agent is added into course of manufacturing printed circuit board washing water
Chemical sterilization algae removal is carried out, production yields and product quality are not influenced, it is a large amount of during can solving due to continuous production
Bacteria growth problems, part process may be used overflow washing, this may make printed circuit board manufacture in normally make
The water consumption that one third to 2/3rds is reduced on the basis of water consumption, solves the environmental protection pressure of producer well.Effectively
Comprehensive production cost is reduced, the speed and quality of production, especially a first-pass yield are improved.The Biocidal algae-killing agent is non-oxide
Property, do not realize that effective sterilization, sterilization component are attached to identification cell membrane function by destroying cell membrane
Carrier on by being effectively combined the progress for preventing cell growth from being metabolized, not will produce drug resistance problems, have and good kill
Bacterium effect, has the function of quick sterilization under certain concentration, and a killing rate is close to 100%.The Biocidal algae-killing agent will not
Adverse reaction occurs with liquid medicine such as existing all plating, any compatibility issues will not be caused to any processing procedures of PCB.
