摘　　要：为了研究洗衣粉溶液的合理使用浓度和温度,利用FD-NST-I型表面张力测定仪测量溶液表面张力系数,同时用pH计进行实验检测。结果表示:0.05%～0.10%的洗衣粉溶液在30.0～45.0℃时表面张力系数较小,更有利于洗净衣物,同时pH值较低,对手及被洗织物都不会产生损害,此区间取值与日常生活习惯相一致。To find the reasonable concentration and temperature of washing powder solution, the coefficient of surface tension is measured by the FD-NST-I liquid surface tension coeffident instrument, and the pH value of solution is also given. Our results show that 0. 05%-0. 10%washing powder solutions in 30. 0℃～45.0℃ is more favorable for washing,and its pH is lower,it will not bring damage to hands and clothes,and the above pa- rameters of washing powder solution are consistent with practical situations.
