   摘要通過正交試驗(yàn)設(shè)計(jì)，研究了低硬度epdm / pp共混型熱塑性動(dòng)態(tài)硫化膠的反應(yīng)擠出動(dòng)態(tài)硫化制備工藝，初步探討了機(jī)筒溫度、喂料螺桿驅(qū)動(dòng)電壓及主機(jī)螺桿轉(zhuǎn)速等主要工藝因素對擠出物微觀相態(tài)結(jié)構(gòu)的影響。
2. 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(jié)果表明： ( 1 ) hdpe彈性體、 xlpe 、 hdpe動(dòng)態(tài)硫化彈性體能夠顯著改善hdpe的形狀回復(fù)能力；在hdpe epdm 、 hdpe nr和hdpe nbr三種共混體系中， hdpe nr的形狀回復(fù)能力最好， hdpe彈性體共混體系的力學(xué)性能和流動(dòng)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(fù)舊管道的襯管材料，共混體系中彈性體含量以15為宜。
