preparation example Construction

[0034] A preparation method of a fixing system cleaner, the steps are as follows:

[0035] Add deionized water or distilled water into the stainless steel container, stir, add sodium sesquicarbonate, ethylenediaminetetraacetic acid tetrasodium salt, diethylene glycol or ethylene glycol, sodium metabisulfite, continue stirring for a period of time, the Stirring speed, add surfactant sodium lauryl alcohol ether sulfate, make up the remaining water and continue stirring to obtain a transparent colorless liquid.

[0036] Further, its preparation method, the steps are as follows:

[0037] The following are based on a weight ratio of 1:

[0038] S1: Add 700 parts of deionized water or distilled water to a 1000-liter clean stainless steel container, and control the water temperature at 30°C-50°C;

[0039] S2: the solution in S1 is stirred, and the rotating speed is at 100 rpm-150 rpm;

[0040] S3: Under stirring, gradually add 80 parts-120 parts of sodium sesquicarbonate; 10 parts...

Abstract

The invention discloses a photographic fixing system cleaning agent and a preparation method thereof. The cleaning agent comprises the following components: sodium sesquicarbonate, ethylenediamine tetraacetic acid tetrasodium salt, diethylene glycol, sodium metabisulfite and lauryl alcohol ether sodium sulfate; the preparation method comprises the steps: adding deionized water or distilled water into a stainless steel container and stirring; and adding sodium sesquicarbonate, ethylenediamine tetraacetic acid tetrasodium salt, diethylene glycol or ethylene glycol and sodium hydrogen sulfite, continuously stirring for a period of time, reducing the stirring speed, adding a surfactant lauryl alcohol ether sodium sulfate, complementing the balance water, and continuously stirring to obtain a transparent colorless liquid. The cleaning agent liquid solution is different from a powder bagged cleaning agent which easily produces flying dust and does not reduce the environmental cleanliness, the liquid cleaning agent is directly and mutually soluble with water, the use is convenient, the cleaning time is saved, the liquid cleaning agent does not contain impurities such as particles, the risk of blocking a circulating pipeline is avoided, and toxic gas is not produced when a fixing solution containing ammonium thiocyanate is cleaned.

Description

technical field [0001] The invention belongs to the cleaning field, in particular to a fixing system cleaning agent. Background technique [0002] Silver salt film processing machine, after a period of use, developing, fixing (or bleaching and fixing) and washing (or stabilizing) tanks and tanks will all produce dirt, if not cleaned regularly, the dirt will stain the processed film or photo paper. Therefore, regular cleaning of the film processor is a necessary condition for the photographic industry, especially the development of PCB photopainting film. [0003] The fixing system (tank and tank frame) cleaners launched on the market are in powder bags, and customers need to pre-dissolve or dissolve them in the fixing tank when using them. shortcoming: [0004] 1. There is powder in the powder bag cleaning agent after use and in the discarded packaging bag after use, which will cause a decrease in environmental cleanliness. For example, the working environment of PCB photo...
