Description
Vynález sa týká spósobu čistenia zariadení pre spracovanie fotografických materiálov.The invention relates to a method for cleaning photographic materials processing equipment.
V zariadeniach pre spracovanie fotografických materiálov sa v priebehu spracovávania vytvárajú usadeniny, ktoré je potřebné odstraňovat. Je známe použitie zriedeného vodného roztoku kyseliny chlorovodíkovéj na čistenie vyvolávacích zariadení. Takýto spósob čistenia je však zdlhavý a náročný.In photo processing equipment, deposits form during processing that need to be removed. It is known to use dilute aqueous hydrochloric acid to clean developing devices. However, such a method of cleaning is lengthy and demanding.
Taktiež je známe použitie čistiaceho prostriedku na báze kyseliny chrómsírovej (Morvay, F. : Maskovacie metody v reprodukčnej fotografii, Alfa Bratislava, 173, 1968). Jeho nevýhodou je skutečnost, že po vyčistění nie je možné čistiaci kúpel vypustit do kanalizácie.It is also known to use a cleaning agent based on chromosulphuric acid (Morvay, F.: Masking methods in reproduction photography, Alfa Bratislava, 173, 1968). Its disadvantage is the fact that after cleaning it is not possible to drain the cleaning bath into the sewer.
Uvedené nedostatky odstraňuje spósob čistenia zariadení pre spracovanie fotografických materiálov podlá vynálezu.The method of cleaning the photographic material processing device according to the invention eliminates these drawbacks.
Podstata vynálezu spočívá v tom, že na znečistěné zariadenie sa pósobí 0,5 až 2,6 %-ným vodným roztokom manganistanu draselného a 1,0 až 2,5 %-ným vodným roztokom kyseliny sírovéj počas 10 až 30 minút za cirkulácie, po ich odstránení a vypláchnutí zariadenia vodou 30 až 40 °C teplou sa na zariadenie pósobí dalších 10 až 30 minút 1,0 až 2,5 %-ným vodným roztokom kyseliny štavelovej. Vyčištěné zariadenie sa nakoniec dokonale vypláchne vodou (dvakrát, 10 minút pri zapnutej cirkulácii) až do odstránenia zbytkov čistiacich roztokov.The essence of the invention is that the contaminated device is treated with a 0.5 to 2.6% aqueous solution of potassium permanganate and a 1.0 to 2.5% aqueous solution of sulfuric acid for 10 to 30 minutes with circulation, after after removing them and rinsing the apparatus with water at 30 DEG to 40 DEG C., the apparatus is treated for a further 10 to 30 minutes with a 1.0 to 2.5% aqueous solution of oxalic acid. Finally, the cleaned equipment is thoroughly rinsed with water (twice, 10 minutes with the circulation switched on) until the residual cleaning solutions are removed.
Výhodou spósobu čistenia zariadení pre spracovanie fotografických materiálov podlá vynálezu je predovšetkým jeho rýchlosť; okrem toho nedochádza k poškodzovaniu čištěných zariadení (vyvolávacie tanky ap.) a čistiaci kúpel je možné hned po vyčistění - bez úpravy - vypúšťať do kanalizácie.The advantage of the method of cleaning photographic material processing devices according to the invention is in particular its speed; in addition, the cleaned equipment (developing tanks, etc.) is not damaged and the cleaning bath can be discharged into the sewer immediately after cleaning - without treatment.
Příklad 1Example 1
Příprava čistiacich roztokovPreparation of cleaning solutions
Roztok A: 64 kg manganistanu draselného, do 1 000 ml vodaSolution A: 64 kg of potassium permanganate, to 1 000 ml of water
Roztok B; 10 ml koncentrovanéj kyseliny sírovej, do 1 000 ml vodaSolution B; 10 ml of concentrated sulfuric acid, to 1 000 ml of water
Roztok C: 100 g kyseliny štavelovej .2^0) , do 1 000 ml vodaSolution C: 100 g of oxalic acid (2.0 ml), to 1000 ml of water
Jednotlivé roztoky sa připravili rozpuštěním zložiek v 1 000 ml vody za stálého miešania .Individual solutions were prepared by dissolving the components in 1000 ml of water with stirring.
Příklad 2Example 2
Do znečistěného vyvolávacieho tanku sa nalialo 100 1 30 °C teplej vody, přidal sa 1 1 roztoku B. Pri zapnutej cirkulácii sa čistiaci kúpel nechal 10 minút pósobiť. Po 10 minutách sa znečistěný kúpel vypustil, tank sa vypláchol vodou 30 °C teplou, opať sa naplnil 100 1 30 °C teplej vody, do ktorej sa přidal 1 1 roztoku C. Tento čistiaci roztok sa opať nechal pri zapnutej cirkulácii pósobiť 10 minút.100 l of 30 [deg.] C. warm water were poured into the contaminated developing tank, 1 l of solution B was added. With the circulation switched on, the cleaning bath was left to act for 10 minutes. After 10 minutes, the contaminated bath was drained, the tank was rinsed with 30 ° C warm water, refilled with 100 L of 30 ° C warm water, to which 1 L of Solution C was added. This cleaning solution was again allowed to act for 10 minutes with the circulation on.
Po 10 minútach sa znečistěný roztok vypustil a vyčištěný vyvolávací tank sa dvakrát vypláchol vodou až do odstránenia zvyškov čistiaceho roztoku.After 10 minutes, the contaminated solution was drained and the cleaned developing tank was rinsed twice with water until residual cleaning solution was removed.
Příklad 3Example 3
Do silné znečistěného vyvolávacieho tanku (objem cca 25 1) sa nalialo 25 1 40 °C teplej vody, přidal sa 1 1 roztoku A, po premiešaní 1 1 roztoku B. Pri zapnutej cirkulácii sa čistiaci kúpel nechal 30 minút pósobiť. Po 30 minútach sa znečistěný kúpel vypustil, tank sa vypláchol vodou 40 °C teplou, opáť sa naplnil 25 1 40 °C teplej vody, do ktorej sa přidal 1 1 roztoku C. Tento čistiaci roztok sa nechal pri zapnutej cirkulácii pósobiť dalších 30 minút.25 l of 40 [deg.] C. warm water were poured into a heavily soiled developing tank (volume approx. 25 l), 1 l of solution A was added, after stirring 1 l of solution B. With the circulation switched on, the cleaning bath was left to act for 30 minutes. After 30 minutes, the contaminated bath was drained, the tank was rinsed with 40 ° C warm water, again filled with 25 L of 40 ° C warm water, to which 1 L of Solution C was added. This cleaning solution was allowed to act for another 30 minutes with the circulation on.
