Ageing rack and ageing method of thermosensitive film

Abstract

The invention discloses an ageing rack and an ageing method of a thermosensitive film. The ageing rack comprises a main body, trays and installing parts arranged on the main body; and the ageing rackis movably arranged on an ageing production line through the main body, ventilating flowing channels are formed inside the main body and used for circulation of warm and humid gas in the ageing production line, the trays are installed on the installing parts so that the trays can be located in the ventilating flowing passages, and the trays comprise arc-shaped surfaces which are used for placing aplurality of thermosensitive films in a stacked mode. According to the technical scheme of the ageing rack and the ageing method of the thermosensitive film, the ageing conformity of the thermosensitive films can be improved.

Description

technical field [0001] The invention relates to the technical field of photosensitive film manufacturing, in particular to an aging frame and a heat-sensitive film aging method. Background technique [0002] The thermal film is mainly used for imaging in the printer after being exposed to light. The thermal film is generally composed of a base material and various additives to achieve a variety of photosensitive properties. Thermal film generally adopts a layered structure, such as: film base, bonding layer, upper and lower photosensitive emulsion, filter layer and interlayer, etc. In order to make the layers of the thermal film tightly bonded, it is necessary to go through the coating process to achieve delamination during production. [0003] At present, since the thermal film needs to be coated in the whole roll, the chemical composition of each layered structure cannot be in a stable state after coating. Therefore, it is necessary to perform aging treatment on the entir...

AI Technical Summary

Problems solved by technology

[0003] At present, since the thermal film needs to be coated on a whole roll, the chemical composition of each layered structure cannot be in a stable state after coating, so it is necessary to perform aging treatment on the whole roll of thermal film to achieve the purpose of coating curing However, even if the entire roll of thermal film is placed in a constant temperature and humidity environment, the temperature and humidity of the inner and outer layers of the entire roll of thermal film have a large difference in temperature and humidity, and the aging consistency of the thermal film is poor.
