定影和水洗是影片加工中两道很重要的工序,但往往未予重视。本文通过对定影液的成份、搅拌以及温度对定影程度的影响;洗涤水的成份,水洗时搅拌和温度的影响试验,说明这些因素都很重要。试验目的是:(1)尽量减少定影液和水洗水的消耗量;(2)尽可能缩短加工时间;(3)确保影片质量并符合ISO贮藏标准。快速加工不仅已用于医疗用X光片,而且也开始应用到其它方面。如今医疗用X光胶片,从干到干的全过程总共只需要90秒钟。在这短短的加工过程中,对关键的显影虽为人们所重视,但对定影和水洗两道工序却很随意,其后果是很难保证经保管和长期贮藏后的影片质量,尤其是对微粒胶片的质量影响更大。
Fixing and washing are two very important processes in film processing, but are often overlooked. In this paper, the composition of the fixing solution, stirring and the effect of temperature on the degree of fixing; composition of the washing water, stirring and temperature when washing effect test, indicating that these factors are very important. The purpose of the test is to: (1) minimize the consumption of fixer and wash water; (2) minimize processing time; (3) ensure film quality and meet ISO storage standards. Rapid processing has been used not only for medical X-rays, but also for other applications. Today, medical X-ray film, the whole process from dry to dry only a total of 90 seconds. In this short process, attention is paid to the key development, but the two processes of fixing and washing are very random. As a result, it is difficult to guarantee the quality of the film after storage and long-term storage, The quality of the particle film has a greater impact.
