加筋混凝土的电化学realkalization和氯化物萃取处理. realkalization - Electrochemical realkalization and chloride extraction treatments for reinforced concrete - part 1 : realkalization ; german version cen ts 14038 - 1 : 2004
加筋混凝土的电化学realkalization和氯化物萃取处理 - The worm - like mesoporous materials were synthesized and characterized with tem , x - ray diffraction , nitrogen adsorption / desorption and ft - ir techniques , etc . the results showed that all the samples had larger porediameter than the samples through calcinations under resembled conditions , but the mesopore ordered poorly . ft - ir results showed hexagonal structural character were kept , but xrd , tem results showed that the samples have the structure characteristics of msu - x . it was analysized that all n2 adsorption isotherms of the samples belong to langmuir iv category which is related to mesoporous materials
Ft - ir光谱表征结果显示，经萃取处理后的介孔sio _ 2材料保持了六方的结构特征；经xrd 、 tem进一步分析，证实所合成的介孔氧化硅材料具有msu - x材料的结构特征， xrd谱图表明样品具有短程有序性：所合成的材料低温n _ 2吸附测试结果表明，各样品的n _ 2吸附等温线均与中孔(介孔)特征的第类曲线基本相符；由kelvin公式计算得到的孔径分布曲线说明，介孔材料具有较为集中的孔径分布；各样品的bet比表面积比较高。 - The polystyrene particles with 2 . 8 micrometer mean diameter were prepared by dispersion polymerization and hollow porous micro - sphere were prepared by extraction after seeding emulsion polymerization . particles with multi - hollow structure were obtained and characterized by sem , additionally the mechanism and factor about formation of porous structure were also discussed . to prepare the biodegradable nano - particles , reversed - phase micro - emulsion and ionotropic gelation methods were used
利用分散聚合法制得了粒径约为3 m的聚苯乙烯种子微球，再通过溶胀、交联、种子乳液聚合及萃取处理，最后得到中空多孔的聚合微球，并讨论了其成孔机理和各博士论文功能型复合超微粒子的制备研究因素的影响。
