Study on the composition of brazing flux for aluminum alloy
Abstract In this paper used the XRD, IR spectroscopy, chromatography - mass spectrometry, nuclear magnetic resonance analysis, UV absorption analysis of the NHM-X100-20UB thermal decomposition of resin, diluents and Solvay NOCOLOK flux and composition of the main components. Simultaneously a different ratio, measured by Zahn cup viscosity and different ratios of the flux strength and the coating amount of the coating to explore the overall performance of the flux. The experimental results showed that: the main component of flux fume and potassium aluminum fluoride, the main component of the thermal decomposition of 18 resin amide, myristic acid amide, heptyl alcohol and acrylic resin, the main component of the diluent dimethoxy butane and malonic acid, when the diluent is added in an amount 31.2% 23.5% resin by adding an amount of flux added in an amount of 45.3%, the viscosity of the coating amount of 690 17g/m2 coating strength is 2H, brazing agent was great.
