Embodiment 1

[0032] A method for monitoring the temperature of frozen products, comprising the following steps:

[0033] S1: According to the product refrigeration temperature standard and management specification, according to the specific product type and product manual, the temperature change value and failure display color of the temperature change ink are formulated;

[0034] S2: Under the standard of refrigerated temperature, spray the temperature-changing ink on the surface of the product or the surface of the only packaging through inkjet equipment;

[0035] S3: During the refrigeration or transportation of the product, once the temperature change value is exceeded, it will immediately change to the failure display color specified in the product manual, and this color change is irreversible;

[0036] S4: According to the failure display color obtained in the previous step, it can be determined that the product has failed and can no longer be used.

[0037] In this embodiment, the ...

Embodiment 2

[0044] The steps of the method for monitoring the temperature of frozen products and the steps of preparing the temperature-changing ink in this embodiment are the same as in Embodiment 1, and will not be repeated here.

[0045] In this embodiment, the temperature-changing ink is composed of the following components by weight: 65 parts of American Huntsman cycloaliphatic epoxy resin CY179, 30 parts of Amicure PACM curing agent, 30 parts of heat-sensitive pigments, and 30 parts of ordinary pigments parts, 0.7 parts of defoamer, and 1.5 parts of leveling agent.

[0046] Among them, the heat-sensitive pigment is selected from -15°C general blue heat-sensitive pigment (the temperature change value is lower than the general blue), and the ordinary pigment is selected from the medium yellow (presents the medium yellow).

[0047] The temperature value of the prepared temperature-changing ink is -15°C, and it is green below -15°C, that is, the mixed color of the general blue of the heat...

Embodiment 3

[0049] The steps of the frozen product temperature monitoring method in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0050] In the present embodiment, the temperature-changing ink is composed of the following components by weight: 40 parts of Japanese Daicel cycloaliphatic epoxy resin CELLOXIDE 2021P, 20 parts of 4417 curing agent, 30 parts of heat-sensitive pigment, and 0.5 parts of defoaming agent 1 part, leveling agent 1 part.

[0051] Among them, the heat-sensitive pigment is rose red heat-sensitive pigment at -5°C (rose red below the temperature change value).

[0052] The temperature-changing ink is prepared by the following preparation method:

[0053] S1: 40 parts of Japan Daicel cycloaliphatic epoxy resin CELLOXIDE 2021P and 20 parts of 4417 curing agent are added to the dispersion kettle, the control speed is 1500-1800r / min, and the dispersion time is 30-60min to obtain component A;

[0054] S2: Add 30 parts of heat-sensit...

Abstract

The invention discloses a method for monitoring the temperature of frozen products. The method comprises the following steps that: firstly, the temperature response value and failure display color oftemperature response ink are configured according to specific product types and product specifications based on the refrigeration temperature standard and management standard of a product; under the refrigeration temperature standard, the temperature response ink is sprayed onto the surface of the product or onto the surface of the only wrappage of the product by using an ink spraying device; during the refrigeration or transportation of the product, once the temperature response value is exceeded, the color of the temperature response ink immediately becomes the failure display color specified in the product specification, and such color change is irreversible; and finally, the product is determined to be invalid and cannot be used any longer according to the failure display color obtained in the previous step. The method of the invention can solve the problem of hidden quality problems of products during refrigeration or transportation caused by improper management; and the temperature response ink can realize the effect of irreversible discoloration at low temperature, has stable quality, strong acid and alkali resistance, strong adhesion and low viscosity.

Description

technical field [0001] The invention relates to the technical field of temperature-changing inks, in particular to a method for monitoring the temperature of frozen products. Background technique [0002] At present, the country attaches great importance to the quality and safety of food and medicine, especially some foods that need to be refrigerated, vaccines, blood, etc. need to be refrigerated at a certain temperature to ensure the quality, but some illegal elements have caused many quality problems due to improper management during storage and transportation. It is impossible for consumers and relevant management departments to identify, and they can only determine whether the company has violated the regulations through spot checks on the management process. It costs a lot of manpower and material resources, but ultimately fails to achieve the supervision of the market without dead ends. In view of this, a method for monitoring the temperature of frozen products is pro...
