Description
Предметом изобретени вл етс флюс дл пайки меди, латуни и омедненного железа легкоплавким серебр ным припоем с применением солей фосфорной кислоты.The subject of the invention is a flux for brazing copper, brass and copper-plated iron with low-melting silver solder using phosphoric acid salts.
Известно применение аммониевых солей фосфорной кислоты в составе флюсов дл пайки. Однако эти флюсы не пригодны Дл пайки легкими серебр ными припо ми с интервалом те.мператур плавлени 450-55СР.The use of ammonium salts of phosphoric acid in the composition of fluxes for soldering is known. However, these fluxes are not suitable for soldering with light silver solders with an interval of thermal melting point 450-55СР.
Предлагаемый флюс устран ет указанный недостаток и улучшает восстановление спаиваемых поверхностей , что достигаетс применением в составе флюса двухзамещенной аммониевой соли фосфорной кислоты в сочетании с углекислым натрием в соотношении:The proposed flux eliminates this drawback and improves the recovery of soldered surfaces, which is achieved by using a two-substituted ammonium salt of phosphoric acid in combination with sodium carbonate in the composition of the flux in the ratio:
52-68% (NH4b НРО, 48-32% Na2 СОз52-68% (NH4b NRA, 48-32% Na2 CO2
Температура плавлени предлагаемого флюса находитс в интервале 450-550°. При пайке имеетс в виду в основном припой состава: Ag - 58%, Си - 20%, Sn -22%. Дл применени компоненты флюса замешивают па чистом спирте до пастообразного состо ни и полученную насту намазывают на спаиваемый шов.The melting point of the proposed flux is in the range of 450-550 °. When soldering, it is mainly the solder of the composition that is meant: Ag - 58%, Cu - 20%, Sn -22%. For use, the flux components are kneaded with pure alcohol to a paste-like state, and the resulting crust is spread on the weld seam.
