强碱

Some of the matrix have been aminated after the chlorome thylation of the copolymer giving an anion exchange resin.

部分共氯甲基化及季铵化后,制得强碱型阴离子交换树脂。

Compared with alkali-washing electrofining method, no strong acid and strong base were used, no high electric field settling separation tank.

与碱洗电精制法相比，该法不使用强酸强碱，不需要高压电场沉降分离罐。

PTFE fiber has good corrosion resistance, low friction factor, nonflame, strong acid and strong alkali resistance, high temperature and low temperature resistance.

PTFE纤维具有优的耐腐蚀性,低摩擦因数,不燃,能耐强酸、强碱、强氧化剂等强腐蚀性试剂或溶剂,耐高、低温性能优。

A method for determination of nitrogen in N-MnFe by titrimetry with amidosulfonic acid after alkaline distillating separation has been studied in this paper.

本文研究了强碱蒸馏分离-氨磺酸滴法氮化锰铁中氮的分析方法。
