Study on the effect of binder on the properties of aluminum fiber agent
Abstract：In this paper,the infrared spectroscopy,nuclear magnetic resonance, chromatography-mass spectrometry have been used to analyze composition of diluent for aluminum brazing. At the same time the import of binder and the synthetic binder groups was analyzed by spectrum.The effects of the different binders and the amount of binder on the coating amount and coating strength have been. investigated. The experimental results showed that: with the increasing the amount of diluent, binder viscosity decreased. The No.2 synthesis binder is similar to import binder ,the coating amount and coating strength closed to the import binder, can be used as aluminum brazing binder. Diluent mainly consisted of alcohol ether and alcohol mixture. when ethylene glycol: ethylene glycol monomethyl =70:30, the quality of coating, coating amount and coating strength closed to imported diluents.
