Embodiment 1

[0026] In the one-time over-temperature detection method provided in this embodiment, filling material A and filling material B are respectively put into inner and outer airtight containers nested with each other, and the volume of the inner airtight container is 1 / 2 of the volume of the outer airtight container. one twenty-seventh;

[0027] Among them, the filling material A is an aqueous solution of ammonia and ethanol and air, the content of ammonia is 80.9%, and the content of ethanol is 17.5%. When filling at -40 ° C, the aqueous solution of ammonia and ethanol needs to fill 5% of the volume of the inner airtight container. %, the air pressure is one atmosphere; the filling material B is 1% ethanol solution of phenolphthalein and air, filled at -40°C, the volume of the ethanol solution of phenolphthalein is 10% of the volume of the outer airtight container, and the air pressure is one atmosphere .

[0028] This embodiment can indicate that the temperature of the object t...

Embodiment 2

[0031] In the one-time over-temperature detection method provided in this embodiment, filling material A and filling material B are respectively put into inner and outer airtight containers nested with each other, and the volume of the inner airtight container is 1 / 2 of the volume of the outer airtight container. one twenty-seventh;

[0032] Wherein, filler A is the aqueous solution of ammonia and ethanol and air, and the content of ammonia is 27.4%, and the content of ethanol is 48.3%, fills at -40 ℃, and the aqueous solution of ammonia and ethanol needs to fill the inner layer airtight container volume 5 %, the air pressure is one atmosphere; the filling material B is 1% ethanol solution of phenolphthalein and air, filled at -40°C, the volume of the ethanol solution of phenolphthalein is 10% of the volume of the outer airtight container, and the air pressure is one atmosphere .

[0033] This embodiment can indicate that the temperature of the object to be tested, which shou...

Embodiment 3

[0036] In the one-time over-temperature detection method provided in this embodiment, filling material A and filling material B are respectively put into inner and outer airtight containers nested with each other, and the volume of the inner airtight container is 1 / 2 of the volume of the outer airtight container. a quarter;

[0037] Wherein, filler A is water and air, fills at 0 ℃, and water needs to fill 5% of the volume of inner layer airtight container, and air pressure is 1.9 atmospheric pressure; Filler B is anhydrous copper sulfate powder and air, in When filling at 0°C, the anhydrous copper sulfate is 0.2 g, and the air pressure is one atmosphere.

[0038] This embodiment can indicate that the temperature of the object under test, which should always be between 0°C and 20°C, was once higher than 25°C.

[0039] The working principle of this embodiment is that the air pressure in the inner airtight container with higher air pressure increases faster than the outer airtig...

Abstract

The invention provides a one-time over-temperature detecting method. The method comprises the following steps: getting a filler A and a filler B; pouring the filler A into an inner closed container; pouring the filler B into an outer closed container; arranging the inner closed container and the outer closed container by a mutual embedding and sleeving manner, wherein the inner closed container is manufactured from a material which is broken when the difference between the inner pressure and the outer pressure is beyond certain atmospheric pressure, and the inner closed container is broken when the outside temperature varies beyond the temperature limit; mixing the filler A with the filler B, and enabling permanent color changing; determining that the detected article reaches or exceeds the temperature as indicated by an one-time over-temperature detecting device when the one-time over-temperature detecting device suffers from obvious color change. With the adoption of the method, whether the article to be detected or the environment exceeds the temperature limit can be completely monitored within the valid period; in addition, the method is small in cost, applies to mass production and use, and is greatly convenient to the temperature monitoring of foods, drugs or agents and the like.

Description

technical field [0001] The invention belongs to the technical field of temperature detection, and in particular relates to an over-temperature detection method. Background technique [0002] Many foods, medicines, and reagents have strict requirements on heat preservation, and they will deteriorate or fail if they are higher or lower than a certain temperature. And when consumers buy them or before using them, they generally don't know whether they will deteriorate or fail due to being higher or lower than a certain temperature in the process of production, transportation, storage and sales. Existing digital display thermometers or temperature testers with memory functions cannot fully monitor the minimum packaging of each food, medicine or reagent within the validity period. Therefore, there is an urgent need for a novel technical solution to solve this problem in the prior art. Contents of the invention [0003] The technical problem to be solved by the present inventi...
