dynamic vulcanization meaning in English
动态硫化
Examples
- 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
摘要通过正交试验设计，研究了低硬度epdm / pp共混型热塑性动态硫化胶的反应挤出动态硫化制备工艺，初步探讨了机筒温度、喂料螺杆驱动电压及主机螺杆转速等主要工艺因素对挤出物微观相态结构的影响。 - 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
结果表明： ( 1 ) hdpe弹性体、 xlpe 、 hdpe动态硫化弹性体能够显著改善hdpe的形状回复能力；在hdpe epdm 、 hdpe nr和hdpe nbr三种共混体系中， hdpe nr的形状回复能力最好， hdpe弹性体共混体系的力学性能和流动性能随弹性体含量增加而降低； ( 2 ) ldpe耐80原油腐蚀性能很差， hdpe耐80原油腐蚀性能良好；共混体系中hdpe - 2480 nbr ( 15 )耐80原油腐蚀性能良好； ( 3 )作为穿插法修复旧管道的衬管材料，共混体系中弹性体含量以15为宜。 - 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
