在23℃和32℃下,对藻酸盐印模材料和聚醚印模材料调和完成后的流动性进行连续的无间断测定.23℃下,藻酸盐印模材料在调和开始190 s后固化完成,聚醚印模材料在调和后310 s固化完成.32℃下,藻酸盐印模材料在调和开始130 s后固化完成,聚醚印模材料在调和后180 s后固化完成.温度对2种印模材料调和后的操作时间和硬化时间均有影响,对聚醚印模材料的影响更大,临床应用要注意温度的变化.%The flow property of alginoplast alginate impression material(AAIM) and impregum penta polyether impression material(IPPIM) was measured at 23 ℃ and 32 ℃ respectively. At 23 ℃ the flow property of AAIM and IPPIM ended 190 and 310 seconds after mixing respectively, at 32℃ they did 130 and 180 seconds after mixing respectively. The effect of temperature on the flow property of IPPIM was stronger than on that of AAIM.
