Description

A diacetylenic color-changing detection label

technical field

The utility model relates to a detection label, in particular to a diacetylenic color-changing detection label.

Background technique

At present, when high-temperature disinfection is carried out under the existing technical conditions, the disinfection effect is generally achieved by setting the temperature and time of the sterilizer, but this method often causes the internal temperature of the sterilizer to fail to reach due to mutual contact or interference of the sterilized items. Setting requirements and other issues, so that the disinfection requirements of the items to be sterilized cannot be guaranteed, especially the high-temperature disinfection safety of food and medical packaging containers is particularly important. At present, there is still no suitable disinfection product that can closely track the disinfection information of the sterilized items and identify the disinfection status of the sterilized items in time.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a diacetylenic color-changing detection label for identifying whether the temperature and time of high-temperature disinfection have reached the target.

In order to solve the above technical problems, the utility model is realized through the following technical solutions:

A diacetylenic color-changing detection label, comprising a self-adhesive, a color-changing layer, a thermal insulation layer, and a filling material. Between the insulation layers, the area of the discoloration layer is smaller than that of the sticker and the heat insulation layer, and is completely covered by the insulation layer, and the filling material layer is filled in the accommodation chamber formed by the sticker, the discoloration layer, and the heat insulation layer .

The self-adhesive layer is food-grade self-adhesive.

The material of the color-changing layer is a diacetylenic color-changing material, and the temperature is 50°-120°.

The heat insulation time of the heat insulation layer is adapted to the material of the filling material layer.

The filling material is air or liquid.

Compared with the prior art, the beneficial effects of the utility model are:

Through the identification of discoloration, it can be effectively judged whether the sterilized item has been kept at the set temperature within a certain period of time, so as to directly determine whether the item has completed the disinfection process. The manufacturing process of the label is simple, practical and simple, and has high operability, and is especially suitable for the disinfection of packaging containers in the fields of food and medicine safety.

Description of drawings

Fig. 1 is a cross-sectional view of a diacetylenic thermochromic label of the present invention.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

A diacetylenic color-changing detection label, comprising a self-adhesive, a color-changing layer, a thermal insulation layer, and a filling material. Between the insulation layers, the area of the discoloration layer is smaller than that of the sticker and the heat insulation layer, and is completely covered by the insulation layer, and the filling material layer is filled in the accommodation chamber formed by the sticker, the discoloration layer, and the heat insulation layer .

The self-adhesive layer is food-grade self-adhesive.

The material of the color-changing layer is a diacetylenic color-changing material, and the temperature is 50°-120°.

The heat insulation time of the heat insulation layer is adapted to the material of the filling material layer.

The filling material is air or liquid.

As shown in FIG. 1 , a diacetylene temperature-sensitive color-changing label described in the present invention includes a self-adhesive layer 1 , a color-changing material layer 2 and a thermal insulation layer 3 . Paste a diacetylene temperature-sensitive color-changing label product described in the present invention on the surface of the object to be sterilized. When the ambient temperature reaches the set temperature, the temperature will be transmitted to the color-changing material layer 2 through the heat insulation layer 3 to make the color change Layer 2 changes color, thereby judging the temperature and time to achieve disinfection.

The time of heat conduction is controlled by selecting different insulation materials and thicknesses of the insulation layer. If air is used as the heat insulation material, when the thickness of the heat insulation layer is set to 1.4mm and the discoloration temperature is set to 50 degrees, when the outer layer of the label quickly reaches a temperature above 50 degrees due to the heating of the disinfection cabinet , because of the protection of the heat insulation material, the inner temperature is lower than 30 degrees, and the heat of the outer layer will be conducted to the inner color-changing material through the heat insulation material. After 1.7 seconds, the inner temperature exceeds 50 degrees, and the color-changing material changes color. The discoloration can indicate that the object to be sterilized is in a sterilization environment of 50 degrees for at least 1.7 seconds, indicating that the object to be sterilized has been sterilized for at least 1.7 seconds.

According to the above principle of the temperature difference between the inside and outside of the heat insulation material and the time required for heat transfer, when different heat insulation materials and different thicknesses are selected, the speed of conduction and the time of heat conduction can be controlled to set different disinfection times.

Table 1 below shows the different heat transfer times of various filling materials:

The above embodiments are only to illustrate the technical concept and characteristics of the present utility model, and its purpose is to allow those familiar with this technology to understand the content of the present utility model and implement it accordingly, and cannot limit the protection scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the claims of the utility model shall fall within the scope of the claims of the utility model.

This type of label is mainly used to closely track the disinfection status of the sterilized items, and is especially suitable for food and medical safety packaging containers with high disinfection requirements.

The unexplained parts involved in the utility model are the same as the prior art or are realized by adopting the prior art.
