reversible temperature-sensitive color pigments
The principle and structure of the reversible color temperature color pigments:
Reversible temperature-sensitive color pigment type organic compound by the electron transfer system prepared. Electron transfer-type organic compound is an organic chromophore system has a special chemical structure. At a specific temperature by electron transfer of the organic molecular structure is changed, in order to achieve color change. This discoloration substance not only colorful, but also from a “colored === colorless” and “colorless === colored” state of the color change, which is a heavy metal complex salt complex type and liquid crystal type reversible temperature change substances are not available.
Microencapsulation reversible temperature change substance called reversible temperature-sensitive color pigments (commonly known as: temperature change color, temperature or temperature change powder powder). This pigment particles are spherical cylindrical, with an average diameter of 2 to 7 microns (a micron is a thousandth of a millimeter). Its interior is discolored material thickness of the outer layer is 0.2 to 0.5 microns can neither dissolve nor melt the transparent shell, it protects it from erosion discoloration substance other chemicals. Therefore, to avoid the destruction of this crust is important in use.
