摘要
乳剂生产的pBr参数,是决定乳剂晶体的大小,形状结构,以及晶体分布情况的关键指标,一般仪表控制的乳剂生产,pBr不能直接闭环控制,仅仅通过流量的闭环控制来间接控制。本文所阐述的平衡双注乳化控制技术平台,不仅可以实现pBr的闭环控制,还可以根据工艺配方的需求,进行流量的开环、闭环、恒流量、变流量等各种控制,满足复杂配方的控制需求。
The pBr parameter in the photographic emulsion preparation process is the key parameter determining the emulsion grains size,crystals shape,structure and distribution.In normal emulsion preparation processes controlled by instruments,the pBr cannot be controlled directly by a closed control circle,but indirectly controlled by a closed control circle of flow rate of reactants.This paper described a balanced double jet emulsification technology control platform which allows the closed circle control of pBr and also miscellaneous flow control systems e.g.open circle,closed circle,constant flow rate,variable flow rate etc,to meet the requirements of different sophisticated recipes.
