The results of the uni - factor experiments and perpendicular experiments show their best mechanic synthesizing craft as followed : nvp ( 10 % wt ), kh570 ( 20 % wt ), hema ( 70 % wt ), initiator ( 0. 2 % wt ), crosslinker ( 20 % wt ), reacting 20 hours under 80 c. the factors which influenced organic silicon modified pvp hydrogel soft contact lens material ' s swelling capabilities were researched, which included temperature, monomer content, ion concentration etc. the experiments showed the equation swelling content ewc improved with the increase of nw, droped with the increase of kh570 and ion concentration, improved then droped with the raise of temperature, and hydrogels got the least ewc at 45 c. experiment carried on todiscuss water dehydration mechanism of organic silicon modified pvp hydrogel soft contact lens materials, which showed dehydration process could be divided into evaporating stage and diffusing stage
正交實驗結果表明, nvp ? hema ? kh570共聚物的機械性能最佳時,其合成工藝條件為: nvp用量10 (質量百分含量,下同) , kh570用量20 , hema用量70 ,引發劑aibn用量0 . 2 ,交聯劑nmba用量0 . 2 ,反應溫度為80 ,反應時間16h 。討論了單體配比、溶脹溫度、離子濃度等因素對有機硅改性pvp水凝膠軟接觸透鏡材料溶脹性能的影響。實驗得出:水凝膠材料的平衡溶脹度ewc隨單體nvp含量的增加而增大, ewc隨kh570用量的增加而減小,隨離子濃度的增大而略微降低,隨溶脹溫度的升高先稍微下降後有所提高, 45時平衡含水量最低。Putting the potassium permanganate into the filter can improve its effect, the removal of organics and ammonia is increased, the influent concentration can satisfy the water reuse standard. but the turbidity of influent is unsatisfactory. the c / n ratio is the key factor to influence the nitrogen - removal of the anoxic / aerobic two - stage baf when the reflux ratio 、 hydraulic loading and the ratio of gas to liquid in aerobic filter are fixed. the anoxic / aerobic two - stage baf has a good removal of organics at different c / n ratio when the reflux ratio is 2, hydraulic loading is 2. 55m ~ 3 / m ~ 2 ? h and the ratio of gas to liquid in aerobic filter is 3 : 1. the influent concentration of organics is blow 7mg / l. from the beginning to 30cm of the anoxic filter, the removal of the organics is significant ; as the c / n ratio increasing, the influent concentration of ammonia is decreasing. when the c / n ratio is 3. 60, the enfluent concentration of ammonia is 3. 05mg / l which satisfies the water reuse standard. when the c / n ration is less than 3. 60, because of the imperfection
迴流比為2 : 1 ,水力負荷為2 . 55m3 / m2 ? h ,好氧柱氣水比為3 : 1時試驗表明:不同的c / n ( 1 . 05 7 . 45 )下,兩級曝氣生物濾池對有機物有很好的去除作用,出水有機物濃度小於7mg / l ,其中在缺氧柱進水端30cm內對有機物的去除最為明顯;隨著c / n的增加,系統出水氨氮濃度降低,當c / n為3 . 60時,出水氨氮濃度降到3 . 05mg / l ,已經滿足回用水的氨氮標準; c / n < 3 . 60時,因為缺氧柱的不完全反硝化,體系中硝酸鹽氮和亞硝酸鹽氮發生積累影響了好氧柱的硝化反應使氨氮降解效果較差;系統對總氮的去除隨著c / n的增加而增加,當c / n為3 . 60時,出水總氮已經降到11 . 18mg / l ,滿足回用水的要求。According to the features of naphthenic base oil ( i. e., high nitrogen and low sulfur content ) and based upon theoretical analysis of the h2s concentration needed for phase equilibrium of nickel sulfide and tungsten sulfide in hydrogen, the most economic quantity of sulfiding agent injected into the reactor for supplement of sulfur in lube oil hydrogenation catalysts was obtained
摘要針對環烷基油高氮、低硫的特點,通過對硫化鎢和硫化鎳在氫氣中相平衡態所需硫化氫濃度的理論分析,對反應器入口所需補硫量作了詳細的闡述,得出了最經濟的補充注硫量。The main simulation results were as follow : the average energy of electron decreases with the increasing pressure ; it decreases with the increasing methane concentration in the filling gas in the lower pressure range and increases in the higher pressure range ; the number density of fragment h and ch3 does not always increases with the gas pressure, but reaches an individual maximum ; energy carried by neutral dissociative fragment ch3 decreases with increasing gas pressure and ch4 concentration
主要結果如下:平均電子能量隨著反應室內氣壓的增加呈下降趨勢;在較低氣壓范圍內平均電子能量隨著反應源氣體中甲烷濃度的增加而減少;在較高氣壓范圍內平均電子能量則隨著甲烷濃度的增加而增加;隨著氣壓的增加碎片h和ch _ 3的數目並不是一直增加的,而是在不同的特定氣壓下出現各自的最值;碎片攜帶的能量基本隨甲烷濃度和氣壓的增加而減小。The content of styrene was found to be dependent on the investigated grafting conditions, of which the dose rate and monomer concentration were the major conditions, and the dependence of the initial rate of grafting on the dose rate and the monomer concentration was found to be of 0. 4286 and 1. 1662 orders, respectively. the results indicate that the grafting reaction is competitive and the copolymerization and the graft - copolymerization are existing at the same time. the grafting proceeds by the so - called front mechanism in which the grafting starts at the surface of the films and moves toward the middle of the film by successive diffusion of the styrene through the grafted layers
我們對輻射接枝反應中的各個因素如:單體濃度、輻射劑量率、輻射劑量以及反應時間進行了研究分析,結果表明:單體濃度和劑量率是反應的兩個主要影響因素,它們對反應速率的影響指數分別為1 . 1662和0 . 4269 ;反應的動力學方程為: rg k [ d ] ~ ( 0 . 4269 ) [ m ] ~ ( 1 . 1662 ) ;認為接枝反應是一競爭反應,單體的均聚反應和在聚合物上的接枝反應同時存在,單體濃度的高低決定著競爭反應的方向;輻射接枝反應是從聚合物表面開始的,隨著溶劑的溶脹和單體的擴散最後在整個膜體中形成接枝產物。It includes reducing the density of medicines, choosing the optimal medicine proportion, choosing unpolluted catalyst and controlling response time properly
