Machine-developing concentrated solution kit chemical for industrial X-ray films

Abstract

The invention relates to machine-developing concentrated solution kit chemical for industrial X-ray films. The machine-developing concentrated solution kit chemical comprises developing concentrated solutions and fixing concentrated solutions, wherein the developing concentrated solutions include a developing concentrated solution A, a developing concentrated solution B and a developing concentrated solution C, the fixing concentrated solutions include a fixing concentrated solution A and a fixing concentrated solution B. The machine-developing concentrated solution kit chemical has the advantages that the latest model of phenidone Z is adopted as a main developing agent in the developing concentrated solutions, developing solution activity (photosensibility of a film) is improved, matching and use amount of two developing agents (the phenidone Z and hydroquinone) are increased, contrast ratio and the most blackening degree of the film are increased, and an organic developing accelerant and an inorganic developing accelerant are adopted to enable the film to obtain sufficiently high using density and contrast ratio in a film developing and processing process (a procedure fixed by a developing machine).

Description

technical field [0001] The invention belongs to the field of film flushing concentrated liquid kits, in particular to an industrial X-ray film machine flushing concentrated liquid kit. [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, and the film is de...

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
