    The core tip: thermochromic paint contains thermochromic pigment, which will change color obviously with the change of temperature within a certain temperature threshold, and play a role of mark and warning This kind of coating products can be used on various surfaces, such as the high heat discoloration paint on the heat sink, fire door, motor components, etc., which can play a role in fire warning, while the low temperature discoloration paint can be used as a road signal to alert the road and Bridge icing conditions, and a very successful application is to apply it on the handle of the pot, when reaching the hot temperature, the pot will turn bright red to alert Effect The thermochromic materials under study include four categories: 1) Organic compounds Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: thermochromic paint contains thermochromic pigment, which will change color obviously with the change of temperature within a certain temperature threshold, playing a role of mark and warning This kind of coating products can be used on various surfaces, such as heat sink, fire door and electric machine The high heat discoloration paint on the parts can play a role of fire warning, while the low temperature discoloration paint can be used as a road signal to warn the road and Bridge icing conditions Another very successful application is to paint it on the handle of the pot When the temperature reaches the hot hand temperature, the pot will turn bright red to play a warning role The thermochromic materials that have been studied include four categories: 1) the thermochromic polymer based pigment developed by organic compounds can change color reversibly in the range of - 35 ℃ ~ + 125 ℃, and it is stable at high temperature (< 200 ℃), which is composed of microcapsules, and the temperature change value can be controlled artificially by chemical modification When the temperature rises to a certain degree, the color changes with the change of molecular structure, and then returns to the primary color after cooling The mechanism of discoloration may be that heat leads to an equilibrium between two molecules, two stereoisomers or two liquid crystal structures 2) There are many metals and inorganic compounds that exhibit thermochromic behavior Their mechanisms include phase transfer, coordination geometry changes, the balance between different molecular structures, and the change of the number of solvent molecules in the coordination region Transfer metal system and organic metal system are also used as inorganic thermochromic materials Cobalt chloride in inorganic chemicals changes from light pink to blue at 35 ℃, nickel sulfate turns green at room temperature and yellow at 155 ℃ 3) The thermochromism of the polymer results from the planar non planar hook transition of the polymer, and the color will be changed when the polyacetylene structure changes to the butriene structure 4) many gelation of sol gel will undergo reversible change with temperature, which is caused by mutual repulsion between the tension and attraction force of the polymer network Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
