| Abstract: | Synthesizing technologies of furan resin modified with sorbitol and aromatic polyester polyols were studied on the base of existing synthesizing technology of furan resin,and the effect of adding amount and adding time of sorbitol and aromatic polyester polyols on strength of resin bonded sand was also investigated.Consequently the optimal synthesizing technology of furan resin modified with two kinds of polyols was obtained,and the reaction process was analyzed by means of infrared spectroscopy(IR),by whic... |
