据国外报道,在照相冲显机加工液的液面上加一层 Allplas 浮球,可以收到省时、省力及节省药物的效果。照相加工液未遮盖Allplas 浮球之前很容易被空气氧化而迅速失效,以致必须不断更新药液,这样势必增加加工费用,而且耗时费力。如果给药液加入足量的 Allplas 浮球,使其铺满液面,即能防 According to foreign reports, adding a layer of Allplas float on the surface of the photographic processing liquid can receive time-saving, labor-saving and drug-saving effects. Photographic processing solution is not covered before the Allplas float easily oxidized by the air and rapid failure, which must continue to update the liquid, it is bound to increase processing costs, and time-consuming. If the solution is filled with sufficient amount of Allplas float and covered with liquid, it can be prevented
