This thesis was composed in three parts : ( 1 ) the performance of the catalysts for the oligomerization and polymerization of ethylene ; ( 2 ) the comonomer effect of the in - situ copolymerization of ethylene by the bis ( imino ) - pyridyl iron complexes and metallocenes ; ( 3 ) the in - situ copolymerization of ethylene by cobalt - based catalysts and metallocenes
本論文共分為3部分:催化劑性能的評價,雙亞胺基吡啶鐵配合物與茂金屬復配催化乙烯原位共聚中的共單體效應以及雙亞胺基吡啶鈷配合物與茂金屬復配催化乙烯原位共聚。George forrest, a businessman who does industrialised mining in katanga, says that " the development of china means that there is a need to produce an extra 20, 000 tonnes of cobalt per year "
同時,中國的鈷礦石消費穩定增長,因為它需要加工鈷礦石做電池供應給亞洲市場,年需求35000噸。The turnout of smco magnet per year reach 70 tons, products have been exported west europe, north america and southeast areas and countries etc, the export sum for one year is more than thirty million rmb, in the meantime, ngyc is running according to rwtuv iso9001 : 2000 qualtiy system, and was listed in one of the ningbo export products quality guaranteed enterprises. contact person
經過十幾年的創業發展,公司固定資產已達千萬元,擁有各種先進的加工生產檢測設備,年產釤鈷70噸,質量產量均排名全國前列,接近世界先進水平,產品遠銷西歐北美東南亞等幾十個國家和地區,年出口額三千萬元人民幣以上。In part 3, the in - situ copolymerization of ethylene was investigated by the combinations of the cobalt - based catalyst and the metallocene to prepare short - branched polyethylene. the major oligomers catalyzed by the cobalt - based catalyst 5, 6 and 7 werel - butene, and the minor were 1 - hexene. the comonomer effects were also observed
在雙亞胺基吡啶鈷配合物與茂金屬復配催化乙烯原位共聚制備短支鏈支化聚乙烯中,合成了3種雙亞胺基吡啶鈷配合物,研究了反應條件對其催化乙烯齊聚活性和所得產物碳數分佈的影響。On the basis of catalyzing mechanism, it can raise the reaction efficiency of sodium sulfite and reduce the remains of sodium sulfite, and has evident catalyzing action by adding bivalent nickel ions and bivalent cobalt ions into the water under the condition of weak alkali
根據催化機理,在弱堿條件下加入二價鎳離子和二價鈷離子能提高水中亞硫酸鈉的反應效率,降低水中亞硫酸鈉的殘余量,對亞硫酸鈉的除氧效果具有明顯催化作用。The heterogenite is partly treated in furnaces either in dr congo or in neighbouring zambia and then exported mostly to china via south african and tanzanian ports
水鈷礦在剛果金或者鄰國尚比亞入爐進行粗加工然後大部分經南非和坦尚尼亞的港口出口到中國。If the fewer the remains of sodium sulfite in water sample and the lower the water treatment expenditure are, the better the judge criterion is ; cabaltous sulfate catalyzing sodium sulfite is the most applicable deoxidant used for the vapor injection boiler water
若按處理后水樣中亞硫酸鈉的殘余量和噸水處理費用越少越好為衡量標準,硫酸鈷催化亞硫酸鈉除氧劑是最適合用作油田注汽鍋爐用水除氧的除氧劑。With the increasing of knac4h4o6 * 4h2o and naacehso ? ? 2h2o, the speed of plating was increasing when the concentration of them was low
鍍液的ph值與次亞磷酸鈉和硫酸鈷的摩爾比對鍍層成分、及相結構的影響較為顯著。" induction period " was reflected the quality of electroless plating solution, and affected the efficiency of electroless plating, " induction period " was shortened with the increase of the concentration of nah2 ? o2 ? i - ho and coso4. it was shortened by increasing the ph and the loading of powder
硫酸鈷和次亞磷酸鈉濃度的增加,鍍液的ph值升高,裝載量的增大,反應的孕育期變短;鍍速是反應時間與增重綜合作用的結果。If phosphorus was adequacy in composite powder, co - p alloy coating becomes non - crystalline. the quality of composite powder was better, and the stabilization of solution is improved with the increase of the ph from 9. 5 to 11. 0
硫酸鈷濃度18 40g / l ,次亞磷酸鈉濃度20 40g / l ,可以得到鍍覆均勻、分散性好的復合粉末;增加其濃度,復合粉體的鍍覆質量得以提高。分享友人
