ATMP、IDPA等水质稳定剂的性能与其表面张力的关系

PRELIMINARY STUDY ON THE RELATIONSHIP BETWEEN WATER QUALITY STABILIZATION PROPERTIES OF ATMP, IDPA, ETC. AND THEIR SURFACE TENSION

在室温下,用滴重法测定不同浓度的表面活性剂——ATMP(氨基三甲叉膦酸)、IDPA(亚氨基二甲叉膦酸)及PAA(聚丙烯酸)水溶液的表面张力,发现表面活性剂的阻垢性能、缓蚀性能、协同效应与其表面张力之间存在着一定的关系。测定添加表面活性剂后水的表面张力的变化,将有助于预测表面活性剂在工业水处理方面的应用。

The surface tension of surfactant solutions with various concentration was determined by drop weight method at room temperature. These surfactants are ATMP. IDPA. and PAA. It is found that the corrosion and scale inhibition and synergistic effect of these surfactants are related to their surface tension.The application of the surfactant to industrial water treatment can be predicted by measuring the change of the surface tension of the treated water.
