Description

Предлагае мый флюс от.чичаетс  от известных тем, что он HMCOI другой состав, представл ют опреде.,теи1юе сочетап1 е аыгивных компонентов фтористого кальци  и лигатуры алюмпнии-медь-х аг1ги; | с растворител ми бурой и борной кислотой. Применение этого флюса повыи:ает качество соедине к  и обесиечива.ет доио.чиите.и..ный технико-экономический эффект.The proposed flux is derived from the well-known fact that it is a HMCOI different composition, which is defined as the original combination of the active components of calcium fluoride and aluminum-copper-ligatum ligature; | with boric and boric acid solvents. The use of this flux is better: the quality is combined and optimized by the doio.chite.i... technical and economic effect.

Metals, which are located c) to the left of chromium, nickel and iron, oxides of which can be used to restore stainless steel heat-resistant alloys in the process of soldering.

Восстановление окислов может происходить по следуюпиш уравнени м:The reduction of oxides can occur according to the following equations:

Активными компонентами в предлагаемом флюсе  вл ютс  фтористый кальций (5,5-9%) и лигатура (4.о магпи , 48 а.помипп  ц 48:и меди) до 1,3%.The active ingredients in the proposed flux are calcium fluoride (5.5–9%) and ligature (4. o magpi, 48 a.pomipp c 48: and copper) to 1.3%.

Такой состав лигатуры выбран из услови , чтобы она была хрупкой и легко размельчалась в тончайший порошок даже в фарфоровой стуцке. Фтористый ка.изций раствор ет окислы легируюшнх элементов , а лигатура, содержаща  алюмини и маги, восстанавли15ает окислы до металла в процессе пайки.Such a composition of the ligature is chosen from the condition that it is fragile and easily crushed into the finest powder, even in porcelain stutz. Fluoride calcium dissolves the oxides of the alloying elements, and the ligature containing aluminum and magi restores the oxides to the metal during the soldering process.
