Examples
- When butyl acetate and isobutyl acetate were selected as entrainer , tower bottom production contained entrainer , with the further decrease of the ratio of water to entrainer
进料处于最佳进料位置时，分离效果最好。随着进料位置从最佳进料位置上移或下降，分离效果降低。 - Based on the theory of shrinkage , capillary force theory , the influence of road concrete additives in common use on surface tension of water is studied , and the results show that the influence of water reducer is very small whereas shrinkage - reducing agent and air entrainer can reduce surface tension of solution significantly . the relation between surface tension and additive dosage are non - linear relation . each additive has an obvious critical micelle concentration ( cmc )
从混凝土收缩的基本理论? ?毛细管张力理论出发,通过道路混凝土外加剂对水的表面张力的影响研究发现,减水剂对水的表面张力的影响很小,而减缩剂和引气剂可以大幅度降低溶液的表面张力,溶液的表面张力随外加剂的掺量呈非线性形式降低,而且都存在临界胶束浓度。 - Vibration viscosity coefficient of fresh concrete with additives and mineral admixtures are tested . the results show that water reducer and air entrainer can reduce vibration viscosity coefficient while shrinkage - reducing agent has very small influence on it . proper quantity of citric acid , sodium glucaonate or carboxymethy cellulose can reduce vibration viscosity coefficient of fresh concrete
通过对选定的引气剂和减缩剂对硬化混凝土的收缩性能的影响研究发现,引气剂和减缩剂可以大幅度降低混凝土毛细孔中溶液的表面张力,对降低混凝土收缩具有显著作用,当二者复掺时,减缩效果更为明显。 - The influence of packing height , ratio of water to entrainer and acetic acid initial concentration to separation effect of azeotropic distillation was studied in detail . simulation calculations of general distillation and azeotropic distillation were carried out . the influence of reflux ratio , theoretical plate , feed position , feed temperature and feed concentration to distillation process were discussed
( 3 )与普通精馏比较，分离要求相同时，共沸精馏时所需要的理论板数要低于普通精馏所需要的理论板数，回流比减小，可降低设备投资70万元，塔釜加热量减少36 % 。
