  2. Veneer dyeing can improve wood visual characteristics and imitatethe color and luster of precious wood species, to increase the decorative effect. the veneers of hardwood species such as % populus tomentosa, paulownia elongata % were adopted to make dyeing experiments by using acid dyestuff. the result shows : the acid dyestuff in textile industry could be used in wood dyeing process. compound dyeing can be adopted by using the mixture of several kinds of dyestuff. the different treatment methods before the wood was dyed affects the dyeing effect of wood. there is a great difference in the deformed degree of dyeing veneers, smooth level has a relation with wood density. the density of dyestuff, dyeing time and dyeing temperature and so on have many influences on dyeing effect. different technological process has been used in veneers of different wood speicies

    木材單板染色有利於改善木材視覺特性，可以實現模仿珍貴樹種木材的色澤，提高裝飾效果.該研究選取毛白楊和泡桐等闊葉樹種木材單板採用酸性染料進行染色實驗，結果表明：紡織工業用酸性染料可用於木材染色，也可以採用幾種染料混合復合染色；木材染色前的不同處理方法影響木材的染色效果；染色單板的變形程度有較大差異，平整度與木材密度相關；染料濃度、染色時間和染色溫度等對染色效果有較大的影響，不同樹種單板應採用不同工藝

  5. The type of formed nanocomposite was depended on the kind of curing agent used : intercalated nanocomposite was formed for curing agents of deta or mz, and exfoliated nanocomposite was obtained for curing agent of toa

    用二乙烯三胺或咪唑作固化劑時，形成插層型納米復合材料，而用桐油酸酐作固化劑時形成的是剝離型納米復合材料。
  6. ( 2 ) xrd analysis showed that phenolic resin molecules could insert into the interlayer of organic - montmorillonite, but there are some differences of the behavior of intercalation between thermosetting phenolic resin and thermoplastic phenolic resin. ( 3 ) the cure kinetics parameters of epoxy resin / org - mmt / deta, epoxy resin / org - mmt / toa and epoxy resin / org - mmt / mz nanocomposites were investigated by differential scanning calorimetry ( dsc ). some kinetics parameters including the reaction order and activation energy were caculated with kissinger method

    （ 3 ） dsc研究了環氧樹脂二乙烯三胺蒙脫土、環氧樹脂桐油酸酐蒙脫土、環氧樹脂咪唑蒙脫土固化體系在不同org - mmt配比（ 0 ， 5 ， 10 ）及不同溫度下的固化動力學，除了運用常見的kissinger和crane方法求出活化能和反應級數等動力學參數外，還嘗試了用修正的avrami方程和自催化動力學模型研究了環氧樹脂蒙脫土體系的固化動力學。
  7. As to epoxy / toa / org - mmt system, the reaction order was 0. 9 and active energy was 66kj / mol by kissinger method ; and a similar result was obtained by ozawa method. the curing reaction was controlled clearly by diffusion mechanism in the later stage of curing reaction without addition of org - mmt, which leads to the increment of active energy with extend of curing ; as to the curing system with addition of org - mmt, the value of active energy was always kept the same level, which can be explained by the catalytic function of amine salt inserted in the galleries of org - mmt

    對于環氧桐油酸酐有機蒙脫土固化體系用kissinger方法看到固化體系的反應級數均為0 . 9左右，表觀活化能值為66kj mol ； ozawa方法的處理結果與之近似，但從ozawa方法可以看到未加入有機蒙脫土的體系在反應後期固化反應明顯受擴散控制，表現為活化能隨固化程度的增加而增加；而加入有機蒙脫土的體系，其表觀活化能則自始至終表現的較為均勻。
