Why does the cup change color when heated (why does the cup change color when heated)

1, the cup changes color when heated because of its thermal transfer process. The pattern on the mug doesn't usually appear. As long as hot water is added, the pattern will gradually become clear, novel and interesting.

2. To make this kind of cup, it is necessary to print the thermal sublimation ink on special paper with a printer, spray a layer of transparent resin on the surface of the cup, heat it under pressure and temperature, and transfer the special paper to the cup.

After the cup is made, it will change color when heated. The temperature-sensitive material used belongs to the heat-sensitive material, which can withstand the high temperature of about 320 degrees. Does not contain harmful substances, will not cause harm to the human body, and can be used with confidence.

With the continuous development of society, the styles of cups have become various, and the color-changing cup is one of them. The color-changing cup is also called the magic cup. As long as hot water is added, the appearance of the cup will change, just like magic, which is very interesting.

5. In general, color-changing cups are mostly ceramic mugs. Ceramic products need to be fired at high temperature, which has strong high temperature resistance, can withstand high temperatures as high as several hundred degrees, and is safe, environmentally friendly and pollution-free.

6. It should be noted that although ceramic products have good high-temperature resistance, the temperature-sensitive material on the outer layer of the color-changing cup has poor high-temperature resistance, so the color-changing cup cannot be used in high-temperature places such as microwave ovens, dishwashers and disinfection cabinets. It should be kept in a cool and ventilated place.
