Description

Liquid crystal temperature change label

Technical Field

The utility model relates to the technical field of temperature-change labels, in particular to a liquid crystal temperature-change label.

Background

The temperature change label is a common temperature measurement label, and can achieve a function of detecting the temperature of a sample by utilizing the multi-stage temperature change color development function of temperature change ink. The temperature-changing ink is also called thermochromic ink, temperature-indicating ink or temperature-sensing ink, and is a special ink capable of changing color with temperature change. The ink shows a certain specific color at a low temperature, the color disappears to be colorless or other colors after the temperature is increased, and the color changing temperature of the temperature-changing ink is not a temperature point but a temperature interval, namely a temperature range from the beginning of the color changing to the end of the color changing. The width of the temperature interval is generally 4-6 ℃, the label is a variety with higher precision, the color-changing temperature interval is narrower, and the temperature interval is only 0.5-1 ℃. In some sample temperature detection processes, most of the prior temperature-change labels have a color-changing intermediate hue which is difficult to observe by people, so that people feel worse in color-changing sense, the display effect is not obvious, and accurate detection of the sample temperature by users is not facilitated.
