Medical digital paper photographic film and preparation method thereof

Abstract

The invention discloses a medical digital paper photographic film. The medical digital paper photographic film comprises a piece of double-face plastic-coated and film-sprayed paper backing paper, wherein a nanoscale aluminum trioxide powder coating is coated on the surface of the backing paper. Through adoption of the medical digital paper photographic film in the technical scheme, small pollution is caused to the environment in the manufacturing process, harmful gases such as ozone cannot be generated by using ink-jet printing in the using process, and the medical digital paper photographic film can be naturally degraded. The invention further discloses a preparation method of the medical digital paper photographic film; the double-face plastic-coated and film-sprayed paper backing paper is selected to wetly coat the aluminum trioxide powder; the coating average degree is + / - 0.025 mm; the temperature is controlled at 60 DEG C; and a hot air furnace is used for heating. The preparation method of the medical digital paper photographic film, disclosed by the invention, has the advantages that energy consumption can be reduced, pollution can be reduced, the cost of the photographic film is reduced and environmentally hazardous substances substantially cannot be generated in the manufacturing process.

Description

Technical field [0001] The invention relates to the field of medical consumables, in particular to a medical digital paper film and a preparation method thereof. Background technique [0002] The existing medical film production technology is developed through the decomposition of silver halide by laser irradiation. The medical film contains a protective layer, an upper photosensitive emulsion, a filter layer, an interlayer, a middle and lower photosensitive emulsion, a bonding layer, a base, and an anti-halo static layer. . The image component of the film, that is, the photosensitive emulsion layer, is the core part, which is composed of gelatin, silver salt, and additives. Gelatin is a high-grade animal glue extracted from animal bones and skins. Silver salt is a salt compound formed by metallic silver and chlorine, bromine and iodine, which are chemically called halogens. Additives are generally chemical sensitizers, and there are generally potassium bromide that inhibits t...

AI Technical Summary

Problems solved by technology

The medical film of the prior art uses many raw materials, produces long reaction chain compounds, complex synthesis process, high energy consumption, high environmental pollution during the production process, is difficult to degrade naturally, and pollutes the environment

The film development effect of the prior art is poor, the three-dimensional effect is not strong, the definition and gray scale are low, and the cost is high. The ozone generated during laser irradiation in the printer will cause harm to the health of hospital staff.
