The order of preparating liquid can not be put upside down by the numbering standard program, uses enamel, and plastic products, drop into another kind of medicament again and dissolve after stirring confirmed that medicament dissolved fully in 6-10 minute before being equipped with a kind of medicament as stirred vessel; Color developing agent PH=12.5-13 bleach-fixing liquid PH=5-6.After the washing fluid of preparation was stablized 24 hours, it was standby to add 100% clear water dilution back again.The temperature that is fit to the washing fluid operation is 29 °-40 °.
Now the action and function with various chemical agents in the washing fluid is summarized as follows:
One diethyl acetal: be the first liquid that shows of colour reversal film, adjuvant impels photosensitive material emulsion film to expand slightly, adjuvant and phenmethylol dissolving, and the formation benzyl alcohol solution can be used as phenmethylol and helps and add agent in developer solution.It can make developer better play a role after referring to impel the emulsion film to expand, thereby quickens developing process.All contain certain phenmethylol in the colour developing solution of colour negative, printing paper and some colour reversal film of oil-soluble colour paper that high temperature is got express developed and normal temperature flushing.Phenmethylol content is big in general, and it is strong that photochrome presents photographic fog, and light sensitivity and contrast all will increase thereupon; Hour result is opposite for phenmethylol content.Phenmethylol is incomplete same to the influence of three layers of photographic layer of color sensitive material, and phenmethylol is thrown in therefore strict metering according to prescription.
Sodium sulphite: the protective agent that is colour developing solution and stop bath; prevent that in stop bath sulphur from separating out; silver halide there is faint dissolving power; in developer solution as promoter; the effect of intensifying is arranged; belong to alkalescence in developer solution, the pH value in the developer solution has the balanced protection effect of keeping pH value again by sodium sulphite and sodium carbonate or sodium tetraborate metering adjustment.
Potassium bromide: be the inhibitor in the developer solution.Potassium bromide stops the silver bromide reduction that does not possess the weak exposure position of participating in the development degree in the photosensitive material emulsion film, increase the contrast of image and prevent the generation that photographic fog is strong, and can adjust developing powder, consumption hour developing powder is accelerated, but it is strong to occur photographic fog easily, and consumption greatly then developing powder weakens.Potassium bromide is identical with the effect of ammonium bromide, all can be used as bleach boosters.In the color sensitive material washing fluid, make colored silver-colored shadow change into silver bromide photographic fixing on silver bromide change silver thiosulfate sodium complex soluble in water into.
NaOH: belong to alkaline drug, be easy to meet water-solubleization, in developer solution as promoter, but do not possess resiliency, the emulsion film of perishable photosensitive material, in order getting express developed when development needs to adjust pH value or modulation high-contrast developer, to add proper amount of sodium hydroxide and can remove the antihalation layer at the film back side.
Sodium tetraborate: it is better than using the resulting developed grain granularity of sodium carbonate level that its aqueous solution is alkalescent, as the apparent promoter of the head of colour reversal film, adds trace in the bleaching liquid of colored exposure material washing fluid, can adjust pH value.
Sulfuric acid hydroxylammonium: can be used as the additional protective agent of colour developing solution, use the protection color developer effect that reaches with sodium sulphite.
6-nitrobenzimidazole nitrate: get 0.1% solution as colour developing solution, be used as conditioning agent in the photography flushing, consumption is only used 10% aqueous solution of 2-5 milliliter, tests the standard that requires of this soup with pH value, depart from available other medicament as remedying as pH value, meet the requirements of pH value.The too high then development of pH value is too strong.Alkalescence as soup is strong more, can add an amount of aqueous sulfuric acid.
Natrium carbonicum calcinatum: be alkalescence, as the promoter in the colour developing solution, stability is strong, has the effect of intensifying, and also is the host that improves pH value in color developing agent, the bleach-fixing liquid.
Sodium bicarbonate: alkalescence, as the adjuvant of developer solution, keep the pH value of solution, be again development accelerant, again the stronger purificant of surfactivity in bleach-fixing liquid, it and natrium carbonicum calcinatum are used.
Ammoniacal liquor: be alkalescence, as the promoter of developing, can increase developing function sometimes, improve the pH value of solution.
B diammonium edta: make heavy metal ion in the water be converted into the chelate of stable performance, it is just harmless to colour photo development that in a single day heavy metal ion transforms into chelate, therefore also reached the purpose of demineralized water.
Potassium iodide: have hydroscopicity, water soluble, flavescence look behind the aqueous solution chance light is separated out free-iodine.In colour developing solution, add the potassium iodide and the potassium bromide of trace, can promote the dissolving of silver halide.
Ferric trichloride: be used with b diammonium edta.
ATS (Ammonium thiosulphate): with the silver halide effect that is not developed agent reduction in the photosensitive material, generate the silver complex of solubility, photosensitive material is unlikely to continue sensitization again thereby make, and as-reduced silver-colored shadow or dye image are fixed up.It also is a kind of activating agent.Its fixing performance is better than sodium thiosulfate.
Sodium thiocyanate: float and decide auxiliary agent, impel to float and have made to order with thoroughly finishing, its toxicity is less than potassium rhodanide and ammonium thiocyanate.
Sulfuric acid: stop showing agent and add sodium sulphite in the developer soup, its effect is the protective agent in the colour developing solution, prevents separating out of sulphur, is again the stabilizing agent of pH value.Sodium sulphite and potassium bromide, ATS (Ammonium thiosulphate), compatible with each other and its special role all arranged in developer, as potassium bromide is the inhibitor of developer, can stop the reduction of the silver bromide that does not possess the weak exposure position of participating in the development degree in the photosensitive material emulsion, increase the contrast of image and prevent the generation of photographic fog, can also regulate developing powder, consumption hour developing powder is accelerated, but cause photographic fog easily, can cause development capability to weaken when consumption is big.ATS (Ammonium thiosulphate) is fixer in developer, when processing solution is strong basicity (pH value＞13.5), can make colour developing solution carry out photographic fixing when developing.
Ethylenediamine tetraacetic acid and ferric trichloride, NaOH (or sodium carbonate) can substitute the EDTA ferrisodium in traditional bleach-fixing liquid in proportion behind the mixed dissolution, and it is the potpourri of low toxicity.Safe in utilization than the FDTA ferrisodium.Simultaneously a little less than its oxidability, be difficult for reacting to each other unlikely pollution so developer solution and bleach-fixing liquid may reside in the same solution with reductive agent sodium thiosulfate.
Owing to contain fixer in the developer solution, when developing, carry out photographic fixing, developer has high temperature and gets the complementary function that shows photographic fixing express developed, and the medicament major part in the bleach-fixing liquid is the medicine of the same race in the developer, and other medicine is also compatible with developer.So developer can not pollute bleach-fixing liquid, but never permitted with developer opposite chemical reaction to take place so as not to the bleaching agent in the bleach-fixing liquid in the bleach-fixing liquid mixing developer solution, lost developing performance and effect.
If the colour negative photo washes simultaneously, and use same machinery,, float and decide to increase by one in the two procedures washing step developing.
Preparating liquid should be noted following item:
(1) container of preparating liquid should use glass, enamel and plastic products.Stir soup and use glass bar, rubber bar or sticking plaster.Must guard against metallic articles such as using copper, iron, aluminium.
Molten device and apparatus: apparatus should clean up after using immediately, so that use again.
(2) preparing developer liquid, bleach-fixing liquid is used distilled water, deionized water, the water through boiling and cooling off or tap water, contains water softener in the soup.As also using river or well water because of the limitation of conditions.
Coolant-temperature gage generally impels low some medicine that can make again of some medicine accelerated oxidation water temperature to be difficult for dissolving 30 ° of-45 ° of too high meetings of water temperature when (3) preparing.
(4) during preparating liquid, must dissolve one by one by the succession of medicine in the prescription.By the thorough a kind of medicine under the solubilized just after the dissolving of preceding a kind of medicine, can't arbitrarily put upside down its order.Be combined into another kind of chemical agent so as not to a kind of medicament and another kind of medicament.The performance or the chemical reaction that lose development, bleach-fixing liquid play adverse effect.
(5) when preparating liquid, get 3/4ths the water yield of cumulative volume earlier, finish by whole medicines dissolvings, again water is added to desired volume.The water yield also should stir a moment after adding foot, re-uses.
(6) during preparating liquid, note sulfuric acid is added toward water in lentamente, allow anything but in the water adding sulfuric acid.When the preparation sodium sulphite, during as the protection developer solution, dissolve in should aborting earlier, drop into according to the prescription medicament program again, this does not suffer a loss in process for preparation to the protection developer solution, and oxidation is very important.
Combination has b diammonium edta as bleach-fixing liquid, and natrium carbonicum calcinatum, ferric trichloride ratio ground in order drop into stirring chemical molecular ground reaction in the water, produce a kind of EDTA ferrisodium, and it is effective to float silver than EDTA ferrisodium salt.Never allow earlier other several medicaments to be dropped into earlier in the water, to mix earlier stirring also be not all right otherwise lose bleach-fixing liquid with these three kinds of medicines and another kind of medicament.
(7) preparing this soup should ceaselessly stir when the dissolving medicine.The speed that stirs is too not fierce, otherwise can quicken the oxidation of some medicine.Slowly can make the medicine dissolving irregular but can not cross.Should evenly stir by certain orientation during stirring, mustn't positive and negatively stir back and forth, prevent that air from entering oxidation.
(8) the sky gentle pan scale etc. of weighing medicine keeps clean, and should often calibrate, and when using day gentle pan scale or measuring cup graduated cylinder, measuring device should be balanced, and weighing accurate, otherwise can influence this fluidity energy quality.
(9) listed chemical agent all should use pure chemical reagent in the prescription, or indicates the reagent of photography with medicament printed words, never permitted to use contain excessive impurity or through make moist, the medicament of rotten oxidation.
(10) prepare the number of chemical reagent of this soup, should classify to preserve and put shady and cool place and avoid sunlight direct projection or high low temperature storehouse in order to avoid chemolysis is rotten.Just can not deposit together so as not to their chemical reactions or pollution mutually as alkaline agent with acid medicine.
After this soup is mixed with, avoid packing, break in order to avoid move with vial or glassware box jar.Use plastics black Bottle ﹠ Can packing, convenient transportation.
In developing technique, kept development, wash or do not wash with water, it is fixed to float, dry four procedures, though when developing, carried out photographic fixing for the first time, but still kept to float and decided operation, promptly carry out the photographic fixing second time, this is in order to stablize color image purity better, clean the thorough rinsing of chemical reaction particulate of plastic-coated silver bromide emulsion, when silver halide directly was reduced development by solid, the silver-colored shadow covering power of generation was big, chemical reaction forms silver ion in the washing fluid and when it is dissolved in, behind the silver complex ion, be reduced precipitating again on latent image the time, the silver-colored shadow covering power of generation is just little.The present invention adopts high temperature to get technology express developed, adopt the main body of ethylenediamine tetraacetic acid organic oxidizing agent as bleaching agent, oxidized metal silver shadow is a silver ion, and is nontoxic with ethylenediamine tetraacetic acid, substitute the potassium ferricyanide that tradition is used, potassium dichromate inorganic oxidizer with toxicity.
As flushing by hand, can omit washing process.Machinery develops as using, photographic fixing, colour negative and printing paper can be placed in the same machinery, but colour negative and photo after developing must pass through washing process, and the influence of avoiding bleach-fixing liquid bondd by foreign material and silver-colored shadow is reduced simultaneously with surperficial emulsion layer and to be caused ill effect.
Use developer solution of the present invention (A liquid) and bleach-fixing liquid (B liquid), colour negative, colour paper are not subjected to standard temperature, and time restriction can be calculated according to formula flexibly and develop, floats and fix time:
T=W " bt ... (1)
