Gongye shui chuli, 2004 地下水基本没有悬浮物,污染指数SDI低,比较适宜做反渗透的水源,但硬度高,容易引起反渗透膜结垢,故地下水反渗透除盐,预处理的重点是防止膜表面结垢。软化法预处理操作繁琐,设备复杂,讨论了在地下水中加入阻垢剂防止反渗透膜表面结垢的方法,结果表明此法有效可行。

Gongye shui chuli, 1986 硅酸盐被膜剂是一种新型固体水处理药剂。微溶于水,能够在与水接触的金属表面上形成一层厚度为一微米的较硬保护膜,防止了氧化、电化腐蚀;具有良好的防结垢防腐蚀作用,从而达到保护金属设备延长使用寿命的目的。

Gongye shui chuli, 1985 以汽油(或甲苯)为溶剂,过氧化二苯甲酰为引发剂,合成了水溶性顺丁烯二酐、醋酸乙烯酯与丙烯酸或丙烯酸甲酯等其它第三单体的三元共聚物。研究了影响共聚反应的因素与共聚物防垢效果的关系。通过差热和热失重分析,明确了共聚物的热性质。制得的共聚物经油田室内评定和现场应用,被认为具有较好的防垢效果。
