Abstract

The invention relates to a method for monitoring accumulative heating quantity of heat reactive articles and an indicator used by the method. The method for monitoring accumulative heating quantity of heat reactive articles comprises the following steps: (a) providing a heat reactive article; (b) adhering a layer of volatile dye to certain areas of the heat reactive article; (c) adhering a layer of adsorbing materials to the volatile dye; and (d) adhering sealing film to the certain areas and the peripheries of the certain areas, wherein the sealing film enables the adsorbing materials layer and the volatile dye layer to adhere on the heat reactive article in sealing mode, the volatile dye can volatilize under the condition of being heated, the adsorbing materials are adhered on the volatilized dye in irreversible mode, the color fading quantity of the volatile dye layer is in positive correlation with volatilizing quantity of dye, and the volatilizing quantity of dye is in positive correlation with heat absorbed by the heat reactive article. By means of the method for monitoring accumulative heating quantity of heat reactive articles and the time-temperature indicator provided according to the method, heating condition and quality state of the heat reactive articles can be effectively indicated.

Description

technical field

[0001] The invention belongs to the technical field of materials, and relates to a method for monitoring accumulated heat of heat-sensitive objects by using heat-sensitive materials. Specifically, the present invention relates to making time-temperature indicators using the volatile properties of materials, and through the material transfer process of heat-volatility-adsorption, the color change of the functional parts of the indicators can be realized, and the items using the time-temperature indicators are particularly special. It is whether heat-sensitive items deteriorate or fail due to excessive heat. Background technique

[0002] Some items or products whose stability is very sensitive to temperature need to be stored or transported at low temperature, such as most vaccines, biological products, biologically active samples and some pharmaceuticals, as well as fresh milk, dairy products, fresh meat, fresh fish, etc. food etc. For a long time, marking t...
