Title
(EN) ENVIRONMENTAL-FRIENDLY DEVELOPING AND FIXING WASHING LIQUID

Abstract
(EN)
An environmental-friendly developing and fixing washing liquid, comprising a developer, a protective agent, an accelerator, and an inhibitor, and further comprising a defoaming agent, a dispersant, and a cellulose sodium salt. The developer is prepared from hydroquinone independently or by mixing metol with hydroquinone. The mass of metol and hydroquinone is 2-3 g and 5-12 g, respectively. In the process of preparing the developing and fixing washing liquid, the liquid can be effectively dispersed, thereby avoiding the condensing agglomeration in the liquid so that the prepared environmental-friendly developing and fixing washing liquid has good dispersibility and fluidity. Moreover, the manufacturing process is simplified, and the concentration of the disposition liquid can be measured after a primary disposition is completed. The disposition liquid can be effectively protected from contamination by means of vacuum processing, and the environmental-friendly developing and fixing washing liquid having different properties can be prepared according to different mass ratios in formulas.

La présente invention concerne un liquide de lavage de développement et de fixation respectueux de l'environnement comprenant un révélateur, un agent de protection, un accélérateur et un inhibiteur, et comprenant en outre un agent antimousse, un dispersant et un sel de sodium de cellulose. Le révélateur est préparé à partir d'hydroquinone de manière indépendante ou en mélangeant du métol avec de l'hydroquinone. La masse de métol et d'hydroquinone est de 2 à 3 g et de 5 à 12 g, respectivement. Dans le procédé de préparation du liquide de lavage de développement et de fixation, le liquide peut être efficacement dispersé, ce qui permet d'éviter l'agglomération par condensation dans le liquide de telle sorte que le liquide de lavage de développement et de fixation respectueux de l'environnement préparé présente une bonne dispersibilité et une bonne fluidité. De plus, le processus de fabrication est simplifié et la concentration du liquide de disposition peut être mesurée après l'achèvement d'une disposition primaire. Le liquide de disposition peut être efficacement protégé contre la contamination au moyen d'un traitement sous vide, et le liquide de lavage de développement et de fixation respectueux de l'environnement ayant différentes propriétés peut être préparé selon différents rapports de masse dans des formules.
