Ito Ink Coating Chemical Technology launched a high temperature irreversible color recognition ink suitable for aluminum heat treatment recognition
Industrial temperature display irreversible color ink, with separate identification of product hot spots and no spots, such as high-strength aluminum alloy plates; tested at various temperatures, when the temperature rises to the specified temperature, from one color to another color ; After the temperature decreases, the color will not change.
Thermosensitive color change (temperature change) ink is divided into four categories:
1. Display a certain color at room temperature, the color disappears and becomes colorless after heating, and it returns to the original color immediately after cooling. Because of its reversible change process, it is called "reversible temperature change decolorizing ink"
2. It shows colorless at normal temperature, changes to another color after heating, and then returns to the original colorless after cooling. Because its change process is reversible, it is called "reversible temperature change color ink";
3. The ink displays color at normal temperature and changes to another color after heating, because its reversible process is called "reversible temperature change color ink";
4. After heating, it changes from colorless or from a specific color to another color, and the color displayed after heating will not disappear, so it is called "irreversible temperature-changing ink".
The existing varieties are mainly (heating):
1. Reversible temperature change and decolorization (colored and colorless) For example: red → colorless cooling temperature: 10 ℃, 15 ℃, 30 ℃, 40 ℃, 50 ℃, 60 ℃, 70 ℃, 80 ℃, 100 ℃
Second, reversible temperature change color (colorless and colored) 60 ℃ For example: colorless → red colorless → blue cooling heating
Three, reversible temperature change color (colored and colored) temperature: 50 ℃, 60 ℃, 70 ℃, 80 ℃ For example: black → red cooling
Fourth, irreversible temperature change (colorless → colored, colored → colored) Above 65 ℃ For example: colorless → red red → black. Temperatures are: 65 ℃, 80 ℃, 100 ℃, 120 ℃. Other irreversible color temperatures need to be specially customized, ranging from 200 ° C to 500 ° C, up to 1200 ° C.
Industrial temperature irreversible color ink coatings are widely used in communications, power, chemical, transportation, high-pressure containers and other industries. When the temperature of the equipment reaches the preset temperature, the color changes significantly, prompting the staff to check the equipment container in time, paying attention to whether the temperature is too high High burnout can prevent accidents in time and control disasters in the bud.
