表面张力系数实验配制泡泡液

Making the Bubble Liquids with Surface Tension Coefficient Measuring Instrument

应用拉脱法测量分析了一些日用品溶解在自来水中后对表面张力系数的影响,同时测量了一种市售泡泡液的表面张力系数,分析发现市售泡泡液主要成分为水、表面活性剂和甘油,其中表面活性剂主要是用来降低水的表面张力的.利用日用品如洗涤剂、甘油、食盐(NaCl)、胶水等自制泡泡液,测量其表面张力系数的大小并与市售液的数据进行对比,获得较好的配方.

The surface tension coefficient of different solution in same temperature is measured using the FD-NST-I liquid surface tension coefficient measuring instrument. And the surface tension of a commercially available bubble liquid is measured and analyzed in same method. It is found that the main components of the bubble liquid are water,surfactant and glycerol. On that basis,the common items in our daily life such as detergent,glycerol,salt,glue and so on are utilized to make the bubble mixture.
