【摘要】 结垢现象在工业生产中普遍存在 ,化学垢处理剂主要通过对结垢离子 (Ca2 + 、CO2 -3 、SO2 -4 等 )引起的晶核形成及晶体生长过程产生影响。硫酸钙是垢中较难处理的成份之一。本文主要研究了过饱和溶液中二水硫酸钙晶体成核及生长现象 ,同时对垢的形成机理进行了探讨 ,针对这方面的研究有助于开发或选择更经济有效的垢处理剂。更多还原

【Abstract】 The phenomenon of scaling is common in the industrial production.Chemical treatmcnt agents mainly affcct the proccsscs of nuclcation and growth of the crystals causcd by inos （Ca 2+、CO 2-₃、SO 2-₄,etc.）.Calcium sulfate is one of the compositions of scales,which can’t be easily treated with.This article studies mainly the phenomenon of nucleation and growth of calcium sulfate dihydrate crystal,the mechanism of scale fomation is also discussed.The study on this part is helpfoul for developing or selecting more economic and effective scale treatment agents.更多还原
