By using XNR-400 melt flow index tester, the rheological characteristics of PIM feedstock of newly catalytic debinding binder and17-4PH stainless steel powder were studied. 利用XNR-400熔体流速仪,研究了催化脱脂型粘结剂体系和17-4PH不锈钢粉末混合制备的喂料的流变性能。
The effects of polymerization conditions in gas phase and the formulation and preparation of the chromium based polyethylene catalyst QCP 01 on catalyst activity and polymer melt flow index were investigated. 考察了聚合条件以及催化剂配方和制备工艺条件对气相法铬系聚乙烯催化剂QCP-01的聚合活性及产物熔体流动指数(MFI)的影响。
The melt flow index of the blends was increased when the content of PEEK was decreased and melt temperature was increased. 结果表明:共混物的熔体流动指数(MFI)随PEEK含量的降低和熔体温度的升高而增加;
A slight fluctuation in melt flow index of the PP-R power does not affect quality of extrudate and stability of extruding process. 粉料熔体流动指数(MFI)的微小波动,对挤出物的质量和挤出过程的稳定性没有影响;
The rheological behavior of the polyolefin colour masterbatches was studied by dynamic stress rheometer, torque rheometer and melt flow index rheometer. 采用动态应力流变仪、转矩流变仪和熔体流动速率仪研究了聚烯烃色母粒熔体的流变特性。
