  3. Their properties have been investigated by using scanning electronic microscopy ( sem ), differential scanning calorimetry ( dsc ), x - ray diffraction ( xrd ), thermogravimetry - differential thermal analysis ( tg - dta ), infrared spectroscopic analysis ( ir ), and gas chromatography ( gc ), etc. the effects of the mulser ' s stirring rate and the emulsifier concentration on the properties of encapsulated pcms have been systematically studied, and nanopcms have been obtained by increasing the stirring rate or the emulsifier concentration. the influences of different nucleating agents on micropcm performances have also been investigated in detail to search for a suitable nucleating agent to prevent micropcms from super - cooling

    首先，系統研究了乳化機轉速和乳化劑濃度對膠囊性能的影響，並通過提高轉速或乳化劑濃度獲得相變材料納膠囊；其次，系統研究了不同成核劑對微膠囊性能的影響，找到合適的成核劑抑制了相變材料微膠囊的過冷現象；再次，詳細研究了環己烷對膠囊性能的影響，並通過添加適量環己烷提高了相變材料微膠囊及納膠囊的耐熱溫度。
  4. This has an important meaning to the industrial manufacture. dsc, waxd and polarizing microscope with hot stage experiments were performed to describe what led the ssp rate acceleration of pet / mmt. it was shown that montmorillonite acted as a very good nucleating agent in pet crystallization process, which results in the lower crystallinity, more small microlites, and more surfaces of microlites

    為研究pet mmt固相縮聚效率提高的原因，通過熱臺偏光顯微鏡、 dsc 、 x -射線衍射等手段對樣品的結晶進行觀察與分析研究，結果表明蒙脫土對pet的結晶有明顯的成核作用，使其晶核生成速率迅速提高，晶核數量明顯增多，從而使整個結晶過程的時間變短，同時形成了更多結構不完善的微晶體。
  5. The nucleating effects of and nucleating agent on the crystallization behavior of polypropylene ( pp ) were studied by differential scanning calorimetry ( dsc ) and x - ray diffraction spectrum ( xrd )

    摘要用差示掃描量熱儀和x射線衍射儀對兩種類型成核劑改性的聚丙烯的結晶行為進行了表徵。
  6. The results indicate that the addition of a nucleating agent and a thickening agent can inhibit supercooling and eliminate segregation

    結論是，加入成核劑和增稠劑能抑制過冷並消除分層。
  7. In this paper, the crystallinity of pvc modified by homemade nucleating agent and heat treatment was increased. the maximum crystallinity reached 12 %

    採用自製的成核劑對pvc進行噴液處理和熱處理的各種改性，提高了pvc的結晶度，使pvc的結晶度達到了12 。
  8. The development situation and types of nucleating agent for clarified polypropylene are introduced systematically. the prospect of the market and the tendency of technology development are discussed briefly

    摘要介紹了透明聚丙烯成核劑的種類及其在國內外的研究開發進展，並對成核劑的國內外市場現狀、技術開發趨勢做了簡要介紹。
  9. The overall properties of the composite were the best when the content of - nucleating agent was 0. 5 % and the content of aid crosslinking agent was 3 %, the property of the composite came close to that of common engineering plastics

    當成核劑用量為0 . 5 % 、助交聯劑為3 %時，復合材料的綜合性能達到最好，接近普通工程塑料的各項力學性能。
  10. With the addition of nucleating agent, the crystallinity increased, resulted in higher rigidity and lower impact strength than those of pure pp ; while with the addition of - nucleating agent, the relative content of crystalline form of special sheaf - like structure increased and resulted in increase of impact strength and the toughness

    成核劑的加入使聚丙烯結晶度增大，從而使剛性增加，但抗沖擊強度有所下降；成核劑的加入使聚丙烯中晶含量大幅度地提高，從而使聚丙烯抗沖擊強度提高，即韌性增加。
