中文拼音 [tuōguīchǔlǐ]
脫硅處理
英文
desiliconizing treatment-
Explanation : this is kind of sand which is washed. got rid of clay. graded and disposed sarface. and it. saiso molding and core sand used in casting iron and middlesmall sized casting stee
水洗硅砂系列：這是一種經過洗滌、脫泥、分級和表面處理的砂，具有較清潔的原形顆粒，用於鑄鐵件，中小型鑄鋼件的型芯砂。After analysis of the xrd data, an obvious small peak was observed at 29 = 32. 62 ? the experimental results showed that the improved stabilization of the porous silicon layers was due to the formation of sio2 ( 1103 ) structure in the internal surface
Xrd光譜顯示在2口= 32 . 620出現了一個小峰，揭示了經過過氧化氫后處理后多孔硅表面形成了一層二氧化硅（ l10刀）脫，從而提高了多孔硅厚膜的穩定性。2. in this thesis, the mesoporous silica was experimented by using macromolecule microemulsion as template, and template was removed through calcinations and extraction with hot ethanol. the 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 samples " through calcinations under resembled conditions, but the mesopore ordered poorly
首先以剛合成的粒徑均勻分佈的高分子微乳液為模板劑和反應介質，採用萃取和煅燒的方法得到了介孔氧化硅材料，採用ft - ir 、 xrd 、 tem 、 n _ 2吸附脫附曲線等測試手段對經不同處理過的介孔氧化硅材料結構進行了表徵。The changes of specific surface area before and after sintering were measured by nitrogen adsorption. the results show that the surface of sioi particles become coarser along with the remove of polymer template, but the particle size keep no change. the composite microspheres include more uf polymer under low ph value but turn into more looser under high ph value, so the result mesoporous sioi microspheres have big pore volume and average pore size
對脲醛sio _ 2復合微球進行熱處理后得到介孔二氧化硅微球，用示差掃描量熱（ dsc ）熱重（ tg ）分析研究了脲醛sio _ 2復合微球的脫水、脫醇及有機物炭化分解的過程；用氮氣吸附法分析了不同ph值、熱處理溫度對介孔二氧化硅微球的比表面積及孔結構的變化影響；用sem表徵了不同ph值下二氧化硅微球的形貌變化。分享友人
