Manual developing concentrated solution kit for industrial X-ray film

Abstract

The invention relates to a manual developing concentrated solution kit for an industrial X-ray film. The manual developing concentrated solution kit comprises a developing concentrated solution and a photographic fixing concentrated solution. The manual developing concentrated solution kit provided by the inventioncompletely replaces an Agfa imported kit with original packaging, guarantees the quality of domestic large-scale projects, and meets the market requirements. After being prepared into a concentrated solution, the concentrated solution kit is convenient to use and store, multiple integration techniques are used, calcium and magnesium ions are masked, heavy metals like iron, lead, copper, iron and bismuth are also chelated into soluble salts, the kit is completely dissolved, and the cleanness of the kit is guaranteed.

Description

technical field [0001] The invention belongs to the field of film flushing and concentrated medicine kits, in particular to a concentrated liquid medicine kit for manual washing of industrial X-ray films. [0002] technical background [0003] The market demand for industrial X-ray film machine washing concentrate is large, the technical content is high, the production is difficult, and the domestic technical level is lower than that of western developed countries. [0004] Industrial X-ray machine washing kits are usually made into developer concentrate and fixer concentrate. The developing working fluid is made by mixing water, imaging A, imaging B, and imaging C in a certain proportion, and the fixing working fluid is made by mixing water, imaging A, and imaging B in a certain proportion. The developing working solution and fixing working solution are respectively injected into the developing tank, fixing tank and their respective replenishment tanks of the film processor...

AI Technical Summary

Problems solved by technology

[0009] The concentration of the developing solution is low, the activity is poor, the photographic performance of the film after washing is low, and it cannot meet the non-destructive testing requirements of high-energy rays for parts and equipment; the concentration of the developing concentrated solution determines the strength of the developed film and the four indicators of photographic performance. At present, domestic products of this type use all-sodium salt as a protective agent, which crystallizes at around 10°C, making the concentration of the drug solution much lower than the level of "Agfa"

[0010] At present, the wetting effect of the domestic industrial X-ray film machine-washed film is poor, and water stains and false defects often appear, which directly affect the defect detection rate; the fixer concentrate uses sulfuric acid to adjust the acidity. Potassium) hardening agent, it will release sulfur dioxide gas, which will damage human health
