改进化学成熟温度控制系统功能 提高乳剂照相性能的稳定性

Improvement on the function of temperature control system for chemical ripening to heighten the consistency of emulsion photographic properties

彩色感光材料生产工艺要求严格控制乳剂化学成熟温度,容许偏差为±0.2℃。引进的生产线配备有计算机自动温控系统,能达到此精度要求,但在加热或冷却系统运转不正常时,会出现温控滞后现象,导致乳剂报废。从乳剂配方、工艺和计算机程序上进行的一系列改进措施克服了这个弊端。本文系统地报导了这项技术成果。

The production process of color photographic materials requires a strict control of chemical ripening temperature with a tolerance of + 0. 2C . The imported production line is e-quipped with a computerized automatic control temperature system meeting well the above accuracy requirement. However, a delay of temperature control may happen when the heating or cooling devices could not run properly, thus leading to the production of waste emulsion. Through a series of improvement measures carried out on the emulsion recipe, technology and computer programme, this shortcoming was overcome successfully. This paper presents a comprehensive report on this technical achievement.
