Non-reversible color expansion crack type low-temperature measuring device

Technical Field

The invention relates to color-changing temperature measuring equipment, in particular to an irreversible color-changing spalling type low-temperature measuring device.

Background

When an object needs temperature measurement, such as the temperature of a solid or the current environment, the temperature cannot be measured by a simple thermometer, and the existing irreversible temperature measurement equipment mainly comprises temperature measurement paper commonly called a color-changing temperature indicating sheet, a surface temperature label, temperature indicating paper, temperature sensing test paper, temperature sensing test paper or temperature test paper and the like. When the temperature measuring paper is used, the temperature measuring paper is adhered to the surface of an object, the temperature of the object once reached is measured, the corresponding temperature measuring paper can be recorded in a color changing mode when the temperature reaches a certain temperature point, the recording is irreversible, the Chinese standard centigrade degree and the European and American standard Fahrenheit degree are displayed, and the temperature measuring paper is simple, convenient and visual. The temperature measuring device is particularly suitable for the field of temperature measurement of moving objects or the field which can not be reached by the traditional temperature measuring equipment, and the precision is +/-1% of the temperature range. This allows the temperature to be known to which the object has been subjected.

The temperature measuring paper mainly uses a wax melting temperature indicating technology, and the working principle is as follows: the substrate of the temperature measuring paper is usually black, thermosensitive elements with different melting points are coated on the substrate, and when the temperature exceeds the melting point temperature of a certain thermosensitive element, the element is melted and absorbed, and the color (black) of the substrate is leaked, so that the purpose of irreversible temperature measurement is achieved. Based on the principle, the measuring range of the temperature measuring paper is usually 29 ℃ to 290 ℃, however, the temperature measuring paper is not suitable for measuring the temperature below 29 ℃ due to the problems and the defects in the structure, and the requirement of low-temperature (or normal-temperature) storage monitoring of partial food or medicine cannot be met.

Some foods and medicines are generally required to be stored in a low-temperature environment of 4-10 ℃, such as insulin, hepatitis B vaccine, gamma globulin, bifidobacterium, splenomenium, enzymes, probiotics and the like, and when the storage temperature of the medicines is higher than the storage temperature of the medicines, the biological products can be deteriorated and ineffective due to heat. How to carry out whole-process temperature monitoring on links such as storage, transportation and sale of the products is a technical problem which needs to be solved urgently at present.

SUMMERY OF THE UTILITY MODEL

To the problem mentioned above, for overcoming prior art's defect, an object of the utility model is to provide an irreversible discoloration's spalling formula low temperature measuring device can effectively solve prior art's temperature measuring device and can not measure microthermal problem.

For realizing the above-mentioned purpose, the technical scheme of the utility model is, a bloated formula low temperature measuring device of irreversible change look, including seal chamber and discoloration reaction material, its characterized in that, first discoloration reaction material layer is equipped with at the seal chamber center, and the separation dielectric layer is equipped with to first discoloration reaction material layer periphery, and the second discoloration reaction material layer is equipped with in the cavity between separation dielectric layer and the seal chamber, and it reacts to block first discoloration reaction material layer and second discoloration reaction material layer before the separation dielectric layer spalling, and when temperature measuring device was heated, first discoloration reaction material layer was heated the inflation, and the separation dielectric layer is spalled, and first discoloration reaction material layer and second discoloration reaction material layer contact take place to react, discolour.

The utility model discloses simple structure, the modern design is unique, and low in production cost, and is small, can effectively monitor the food or the medicine that need the low temperature storage, guarantees the quality problems of this type of product in the overall process such as dispatching from the factory, transporting, storage and selling, has good society and economic benefits.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

Combine figure 1 to give, the utility model relates to an irreversible change colour's spalling formula low temperature measuring device, including seal chamber and discoloration reactant, its characterized in that, seal chamber 1 center is equipped with first discoloration reactant layer 2, and separation dielectric layer 4 is equipped with to first discoloration reactant layer 2 periphery, is equipped with second discoloration reactant layer 3 in the cavity between separation dielectric layer 4 and the seal chamber 1, and separation dielectric layer 4 spalls and blocks first discoloration reactant layer 2 and second discoloration reactant layer 3 before spalling and reacts, and when temperature measuring device was heated, first discoloration reactant layer 2 is the thermal expansion, and separation dielectric layer 4 is spalled, and first discoloration reactant layer 2 and second discoloration reactant layer 3 contact and react, discolour.

In order to ensure better implementation effect, the sealed cavity 1 is a disc type hollow body or a spherical hollow body made of transparent glass or plastic.

The thermal expansion coefficient of the first color-changing reactant layer 2 is larger than that of the blocking medium layer 4.

The first color-changing reaction substance layer 2 is alcohol containing iodine (the concentration of iodine is 0.1% -20% g/ml), the second color-changing reaction substance layer 3 is starch solution, and the blocking medium layer 4 is solid paraffin.

The diameter of the sealing cavity 1 is 0.3-3 cm.

The utility model discloses in concrete implementation, will the utility model discloses put in the packing of the article that await measuring, when the temperature risees, first allochroic reaction material is heated can the inflation, because the coefficient of thermal expansion of first allochroic reaction material is greater than the coefficient of thermal expansion of separation medium, when first allochroic reaction material inflation, the separation medium can be by the spalling to make first allochroic reaction material and second allochroic reaction material contact mix, the reaction of changing color takes place, the colour becomes blue, through material and the thickness etc. that changes the separation medium, can be in the certain extent, set up the temperature that needs the detection wantonly.

The utility model discloses simple structure, the modern design is unique, low in production cost uses in the packing of the food or the medicine that need the low temperature storage, and this type of product of effective monitoring whether meets with high temperature and leads to rotting or becoming invalid dispatching from the factory, transports, storage and overall process such as sale, has good society and economic benefits.
