| 摘 要： | 本文通过测定胶体的Zeta电位和观察胶粒结构等方法,研究了沉淀过程中加入非离子表面活性剂或阴离子表面活剂对胶体溶液所起到的静电效应和空间位阻效应.结果表明,加入PMG(20000 200)或PAA1460可使胶体分散,防止胶粒的团聚,可制得均匀分散的Zr(OH)_4等胶体溶液.

| Abstract: | This paper, according to the measuring the potential of coloid Zeta and observing its structure, discussed the efTects of nonionic and anionic surface activator on the eletrostatic result and spacial steric effect of the coloid. Experiments showed that putting PEG(20000 200) or PA A1460 in the coloid solution could fractionlize it and therefore prepare Zr(OH)4 uniform and fractional coloid solution. |
