AI Technical Summary
Traditional brazing fluxes are prone to powder particle agglomeration during preparation, have complex reaction steps, and high post-processing costs, making it difficult to obtain nano-sized potassium fluoroaluminate products with fine particle size and uniform distribution.
Nanoscale liquid soldering flux was prepared by using an alcohol/water mixture and adding an emulsifier. The reaction was carried out by an alcohol organic solvent to form a stable nanoscale liquid soldering flux suspension, avoiding the powder processing steps in traditional aqueous phase reactions.
It effectively controls the nucleation and growth of nanoparticles, simplifies the production process, reduces environmental pollution, and allows the product to be used directly in the brazing process without additional mixing, thus improving coating uniformity.
