过氧化氢凝胶化技术研究

对过氧化氢凝胶剂进行筛选的基础上,制备了30wt%与90wt%的过氧化氢凝胶,利用Brookfield流变仪研究了其流变性能,并研究了添加剂对凝胶体系的影响。研究发现,气相二氧化硅与上海产的二氧化硅纳米粉可以将30wt%与90wt%过氧化氢溶液凝胶化,其它微纳米二氧化硅及表面亲酯性修饰的二氧化硅不具有凝胶行为,小分子量有机化合物胆固醇类衍生物也不能使过氧化氢水溶液凝胶化。结果表明凝胶剂表面特性及其粒度大小对其凝胶行为有较大影响,而氢氟酸与部分表面活性剂可以提高凝胶的热稳定性。

Research on gelled hydrogen peroxide

Hydrogen peroxide(30 wt% or 90 wt%)gel system was prepared by selecting gallant .The reheological property was investigate with Brookfield rheometer. Influence of additives on gel system was also researched. The experiment shows that gas phase silica dioxide and nano silica dioxide can make hydrogen peroxide(30 wt% and 90 wt%)form gelation. The result shows that gel superficial characteristic and its particle size effect gelling capability, but idrofluore and some surface active agent can enhance its thermostatbility.
