The factors influencing on the performance of ash - jd such as the moore ratio of monomers, the reaction temperature and time, concentration, the ph value of reaction solution and the drippy speed of formaldehyde were studied carefully. through experiments, the optimum level of those factors was gained
論文詳細研究了反應單體的摩爾比、反應溫度、時間、濃度、反應溶液的酸堿度及甲醛的滴加速度等對產品ash - jd性能的影響,通過試驗,得到了這些因素的最佳水平。Using molecular imprinting method, the 1, 3 - dimethylxanthine theophylline, tho molecular recognition membranes, containing an segments as membrane formation sites and aa segments as functional sites, were prepared by the phase inversion technique. here, tho was selected as a template molecule. the hydrogen bonding between aa segments and the tho templates was measured by ft - ir and nmr. the tho templates can be removed from the membrane through washing with acetic acid aqueous solution. the permeation of tho through the membranes is far more than that of 1, 3, 7 - trimethylxanthine caffeine, caf, which demonstrated the function of tho molecular recognition of the membrane. the results also show that the increase of the tho templates concentration in the cast solution caused an increase of tho amounts taken into the copolymer membrane
Ft - ir及nmr測試結果表明:制備的高分子膜中, tho模板分子和膜中的丙烯酸功能殘基存在著氫鍵鍵合作用。大量的極性醋酸水溶液可抽出膜中的模板分子。 tho溶液和與模板分子具有相似結構的1 , 3 , 7 -三甲基黃嘌呤咖啡因, caf溶液的基質透過實驗結果:進入膜結構中tho分子的量遠大於caf分子,這表明制備的高分子膜具有tho分子識別功能。Testing method for corrosion of fine ceramics in acid and alkaline solutions

硝酸纖維素溶液中活性溶劑稀釋比的標準試驗方法With the very low water to cement ratio, rpc has ultra - high strength high ductility and low permeability. in this paper, the compressive strength of rpc can reach to a high point with the number approximately 135mpa. as illustrated from the study results, we can approve some fundamental conclusions : there are big effects on rpc with deferent kinds and properties of raw materials and deferent curing conditions ; stress - strain curve shows the process of destroy with rpc samples ; x - ray diffraction analysis indicates that heat treatment at temperatures 90 accelerate the hydration of rpc sharply, therefore, mechanical and microstructural properties of rpc are highly dependent on heat treatment ; it is believed that rpc materials have excellent resistance to chloride permeability ; during the heat treatment, the shrinkage of rpc developed quickly because of chemical reactions ; the rpc with slag mostly has the advantage of rpc without slag about resistance to solutions corrosion
研究結果表明:通過對rpc各組分摻量變化的研究,可以找到rpc的最優配合比;試件成型后的熱養護制度對rpc的性能影響巨大; rpc的抗壓應力?應變曲線可以反映出試件受破壞時微裂紋的擴展情況,剛纖維的摻入可以大幅改善rpc的韌性; rpc在成型后存在較大的收縮,而其中的化學收縮要遠遠大於乾燥收縮; rpc具有很強的抗氯離子滲透性能,漿體的密實度很高;通過x射線衍射實驗,可以發現rpc的膠凝體中ch晶體已經幾乎不存在,膠凝體主要由c - s - h凝膠和未水化水泥顆粒組成;在抗溶液侵蝕的實驗中,摻礦渣rpc的抗溶液侵蝕性能在絕大多數情況下要好於不摻礦渣試件,酸、堿溶液和浙江工業大學碩士學位論文摘要一些鹽溶液都會對rpc的結構產生侵蝕作用,但是機理各有不同。Testing of glass - resistance to attack by a boiling aqueous solution of hydrochloric acid - method of test and classification
