We cannot directly dissolve temperature-sensitive and color-changing pigment in water. If we want to prepare thermal paste, we can directly mix it with transparent ink before use. In addition, thermochromic powder can also be used for color matching. We can match color-changing pigments with different colors/color-changing temperatures/series. In this way, we can obtain more colorful color-changing effect.
Temperature-sensitive and color-changing cup is a kind of cup that changes color when heated. For hot color-changing cup, when the water temperature is above 40℃, it will change color. For cold color-changing cup, when the water temperature is below 20℃, it will change color. Water-sensitive and color-changing cup has not been popularized now. The principle is that the thermochromic powder pigment is painted on the cup wall and the material is a kind of heat-sensitive material.
