The Desider Processor Film Dirty Point Analysis and Exclusion

I plant purchased the matching equipment of the Sailing Angel Whole Page Imposition System. The photo grouping and developing machine used less than a month to find that the photo-removal film had appeared dirty after fixing, fixing, and washing. The same phenomenon occurs after the water tank and the rubber roller are scrubbed and dusted.

We analyzed this kind of failure and thought that it might be impurities in the water, but why did the film produced by the M95 processor used for many years under the same conditions cleaner? Then we compared the two developing machine structures and found that Hope The developing machine adds a circulation pump to the washing department so that impurities and film residues that should have settled in the bottom of the water tank are pumped up by the circulation pump, and the water is mixed and mixed, resulting in residual dirt on the film and causing the film to appear dirty.

There is a circulation pump in the developer and fixer. Its purpose is to make the temperature of the developer and fixer uniform. Washing the part with a circulation pump is a good thing, and its effect is counter-productive. In addition, the DQ265/DQ228 processor washing machine previously used by us has not installed a circulation pump. Based on this situation, we removed the circulation pump in the lower part of the machine and operated normally. The quality of the punched film was greatly improved.
