以六次甲基四胺取代水解聚丙烯腈钠盐为主剂的高温堵水剂原配方中的甲醛,以草酸取代盐酸调节pH值,经改进的堵水剂使用安全、无毒,成胶时间的控制比较准确,适用温度下限由100℃扩展到了80℃。
Hexamethylenetetramine to replace the hydrolysis of polyacrylonitrile sodium salt as the main agent of the high temperature water-blocking agent in the original formulation of formaldehyde, oxalic acid instead of hydrochloric acid to adjust the pH value, the improved plugging agent to use safe, non-toxic, gelatin Time control more accurate, the applicable temperature limit extended from 100 ℃ to 80 ℃.
