The mass percent of described aqueous scaling powder raw material is as follows: cetyl trimethylammonium bromide 0.01%-0.1%, sodium hypophosphite 20%-30%, phosphatase 24 0%-50% and deionized water 25%-30%.
Embodiment one
The mass percent of described aqueous scaling powder raw material is as follows: cetyl trimethylammonium bromide 0.01%, sodium hypophosphite 20%, phosphatase 24 0% and deionized water 25%, the process that system is joined first puts deionized water in a reservoir, then in container, add phosphoric acid, next adds sodium hypophosphite, finally adding cetyl trimethylammonium bromide, uniform stirring completes preparation after 30 minutes.
Embodiment two
The mass percent of described aqueous scaling powder raw material is as follows: cetyl trimethylammonium bromide 0.05%, sodium hypophosphite 25%, phosphatase 24 5% and deionized water 27%.First putting deionized water in a reservoir in the process that system is joined, then add phosphoric acid in container, next adds sodium hypophosphite, finally adds cetyl trimethylammonium bromide, and uniform stirring completes preparation after 30 minutes.
Cetyl trimethylammonium bromide one surfactant, surface tension of liquid can be regulated, activity is strong, bright spot, rosin joint, weldering electricity full there is certain effect, sodium hypophosphite improves the reproducibility of scaling powder, phosphoric acid can regulate pH value, also has the content reducing pure water, reduces fried plumbous problem in production process.
The aqueous scaling powder that invention adopts is of value to the cast welding effect of plumbous cast panel grid, eliminate the oxide layer on lug surface, it is to avoid lug reoxidation, lug and lead solution is made better to fuse, decreasing the quantity of pore on grid, and reduce the volume of pore, the grid surface being is smooth.
