  • Through orthogonal experiment design , the preparation technology of reactive extrusion dynamic vulcanization for low hardness epdm / pp blend thermoplastic dynamic vulcanizates was studied , and the effects on micromorphology of extruded vulcanizates of such main technological factors as barrel temperature , feed screw driven voltage and host machine screw rotation rate were discussed
    摘要通過正交試驗設計,研究了低硬度epdm / pp共混型熱塑性動態硫化膠的反應擠出動態硫化制備工藝,初步探討了機筒溫度、喂料螺桿驅動電壓及主機螺桿轉速等主要工藝因素對擠出物微觀相態結構的影響。
  • At last the material and the craftwork are attempted to repair a pipe . the results show that : firstly , all of hdpe / elastomer , xlpe , hdpe / dynamic vulcanization elastomer can obviously improve the shape recovery properties of hdpe ; the shape recovery properties of hdpe / nr is the best among the three kinds of blended system hdpe / epdlvl hdpe / nr and hdpe / nbr , but the mechanical properties and flow behavior will decrease in a certain degree . secondly , hdpe and hdpe ( 2480 ) / nbr ( 15 % ) have the better anticorrosion to hot crude oil , and the anticorrosion of ldpe is the worst ; thirdly , the content of elastomer should be about 15 wt % if the blended system is used in the intercrossing method in repairing old pipes
    結果表明: ( 1 ) hdpe彈性體、 xlpe 、 hdpe動態硫化彈性體能夠顯著改善hdpe的形狀回復能力;在hdpe epdm 、 hdpe nr和hdpe nbr三種共混體系中, hdpe nr的形狀回復能力最好, hdpe彈性體共混體系的力學性能和流動性能隨彈性體含量增加而降低; ( 2 ) ldpe耐80原油腐蝕性能很差, hdpe耐80原油腐蝕性能良好;共混體系中hdpe - 2480 nbr ( 15 )耐80原油腐蝕性能良好; ( 3 )作為穿插法修復舊管道的襯管材料,共混體系中彈性體含量以15為宜。
  • The development history of preparation technology of reactive extrusion dynamic vulcanization for thermoplastic dynamic vulcanizates was introduced , and reactive extrusion dynamic vulcanization technology , including its characteristics , preparation technology conditions , vulcanization rate and vulcanization process , was systematically discussed
    摘要介紹了制備熱塑性動態硫化膠的反應擠出動態硫化技術的發展歷史,系統論述了該技術的特點、工藝條件、硫化速率及硫化過程。
