The effects of type of emulsifier, type of ethylenically unsaturated carboxylic acid and its degree of neutralization, the manner of monomer addition, and the speed of agitator on polymerization were examined. 考察了乳化剂、乙烯基型不饱和羧酸单体及其中和度、加料方式、搅拌器转速对聚合反应的影响。
High speed unequal diameter, multilayer mainshaft of vertical agitator has high alternating stress and fracture happens often. 高速不等直径、多层叶片立式搅拌主轴工作时受到较大的交变应力作用,断裂问题时有发生。
X_Q decreased as the speed of agitator increased, but the trend became weaker. 随着搅拌转速的增加,XQ减小,但其减小的趋势逐渐变缓;
The result shows that rotation speed of agitator and the concentration and interface of catalyst are the major causes and the catalyst regeneration and deterioration are also the cause. 结果表明:搅拌器转速、催化剂浓度、催化剂界面是影响催化剂流失的主要原因,催化剂的再生、劣化也是影响催化剂流失的原因。
X_Q increased greatly as the viscosity of water solution of HEC increased at the same speed of agitator, but the trend became weaker. 在相同转速下,XQ随着流体黏度的增加而增加,但增加的趋势有所减缓;
Speed of agitator must be changed according to the change of height of inclined plates, so that a good separation index can be reached. 要取得较好的分选指标,搅拌器转速必须随着斜板高度变化而变化。
