摘要
该文借助TGA(热重法)、IC(离子色谱分析)等分析手段,研究了Na^+、K^+、Mg^(2+)对纸面石膏板粘结性能的影响。结果表明:Na^+、K^+对纸面石膏板的粘结性能基本没有影响,Mg^(2+)可以比较明显降低纸面石膏板的粘结性能;改性淀粉可以在一定程度上改善由Mg^(2+)浓度过高导致的粘结性能问题,但仍需在今后科研工作中找到更优的问题解决方案。
The effects of Na+, K+ and Mg2+ on the bonding performance of paper plasterboard were studied by means of TGA(thermal gravimetric method) and IC(ion chromatography). The results showed that Na+ ,K+ didn't affect the bonding performance,but Mg2+ decreased significantly the bonding performance; modified starch can improve the bonding performance caused by high concentrations of Mg2 + in a certain extent, but we are still needed to find better solutions to problems in the future research work.
