| Abstract: | The curing process and cured strength of the used sands heated by different temperature used phosphoric acid(H_3PO_4)and paratoluene sulphonic acid (PTSA) as catalyst were compared by test. The different used sands were observed by scanning electron microscope (SEM) and were analysed by energy level equipment. The causes that residual catalysts affect the curing velocity and cured strength of used sand bonded with furan resin and reclaimed furan sand were studied and discussed deeply. |
