Product Description
The printing films high-temperature and rapid-processing developer and fixer being produced domestically now make serious pollutions to film processors more or less, thus damaging their functions. For example, thick film shedding and developer oxide on rubber rollers block up the circulation system of film processor, and result in an accumulation of thick stain that can not be removed by water in the developing and fixing troughs. A long-term use of this product will lead to the cracks of rubber rollers, break circulation installations and increase maintenance costs. The machines, which should have a regular service life of over 10 years, may become scrapped after a short-term service merely due to quality problems of this product. To solve the above problems, our factory, through many years research, has produced developer & fixer up to international advanced level, which proves to be fully able to settle the above.
Purpose:
Suitable for developing a whole series of plate-made films (electronic scanning films, bright & dark-room copies, helium neon, radium emanation, infrared ray, photo-composing films and photo-composing photographic paper) by working with all kinds of high-speed film processor.
Features:
a). Wide processing latitude, sharp contrast and clear dots.
b). Suitable for a whole series of plate-made films by working with high-temperature & rapid-processing film processor.
c). Scrubbing and washing the mechanical parts of the developing and fixing troughs with clean water to get them clean during a change of the developer & fixer.
Dilution:
a). For developing, the dilution proportion of working solutions is 1:2 (developer: water) with a replenishing volume of 150-200ml per square meter film.
b). For fixing, the dilution proportion of working solutions is 1:4 (fixer: water) with a replenishing volume of 200-300ml per square meter film.
Instructions before use:
Before the first use of our international-level developer & fixer, special-purpose cleaners should be applied for rinsing every part of developing troughs to get them clean. If the film processors have been seriously polluted, following circumstances will occur:
a). Film developer becomes grayish black with much sediment at the bottom of the troughs that all are the pollutants of the machines.
b). After the occurrence of the above, the efficacy of the developer will be greatly reduced and haze will appear when the condition gets much worse.
c). Regular horizontal pollutant marks and a layer of bright silver grey matter will appear on the film when developed films come out.
d). The ways of solving the above problems: Clean the troughs with the special-purpose cleaners according to the instruction and then renew film developer. Brush and wash the troughs with clean water every 2 to 3 moths from then on, which will keep the film processors clean.
