摘　　要：目的探讨在含氯消毒液中的浸泡时间对石膏硬度的影响。方法采用含氯消毒液对石膏试样浸泡10 min、20 min、30 min、60 min,按照ISO6507-1标准进行硬度实验。结果不同浸泡时间的石膏硬度差异无统计学意义(P>0.05)。结论石膏经过含氯浸泡消毒后,硬度未发生明显变化。Objective To study the effect of immersion time of chlorine-containing disinfectant on the hardness of gypsum. Methods Hardness test was carried out according to ISO6507-1 standard by using chlorine disinfectant for 10 min,20 min,30 min and 60 min. Results There was no significant difference in the hardness of gypsum in different immersion time（P〉0.05）. Conclusion The hardness of the gypsum after disinfection by chlorine immersion does not change obviously.
