THE WATERSOLUBLE FLUX SLURRY AND THE MANUFACTURING METHOD THE BRAZING PROCESS OF ALUMINUM ALLOYS

摘要

An aqueous flux slurry and a using method thereof are provided to prevent the environmental contamination due to flying of the aqueous flux. An aqueous flux slurry which is used for an aluminum blazing method is made from; glycerin 3~25 wt.% of the hydroxyl radical compounds; and the mixture of glycol compound 3~30 wt.%, flux 10~50 wt.% and water 1~25 wt.%. The hydroxyl radical compounds contain the glycerin, diolein, coconut oil, oleic polyglyco.
