本文所介绍的是银回收自动装置。该银回收控制器可连续测量定影液中银的浓度,并自动进行三级控制。该控制器除了可调节电流密度和自动操作中的电池数外,还能以克/升单位对银的浓度进行数字显示。本文还讨论了不同的银传感器系统,参考溶液以及控制器的操作及内部功能等问题。在电影胶片加工室中,一般的过程是对定影液的银进行分析,并调整电解回收银电解池的电流密度或使用中的电解池数,每天或每班做一次典型分析,但对于高速显影的机器,由于经常加工不同的片种,很难确定出一个回收银的最佳条件,而使用一个银控制器的自动控制器,就可连续测量定影液中银的浓度,并自动进行不同级别的输出控制,或是开/关型的或更为理想的三级控制型(开/低/高),这些控制在操作中用于自动调节电流密度或电解池数目。
This article describes the silver recycling automatic device. The silver recovery controller can continuously measure the concentration of silver in the fixer and automatically perform three levels of control. In addition to the adjustable current density and the number of batteries in automatic operation, the controller digitally displays the silver concentration in g / l units. This article also discusses different silver sensor systems, reference solutions, and controller operation and internal functions. In the motion picture film processing room, the typical process is to analyze the silver in the fixing solution and adjust the current density of the electrolytic silver cell or the number of electrolytic cells in use to perform a typical analysis on a daily or weekly basis. However, for high speed development Of the machine, due to the frequent processing of different slices, it is difficult to determine the best conditions for the recovery of silver, and the use of a silver controller automatic controller, you can continuously measure the concentration of silver in the fixing solution and automatically carry out different levels of Output control, or on / off or even more ideal three-stage control (On / Low / High), these controls are used in operation to automatically adjust the current density or the number of cells.
