The discoloration cup discoloration tumbler can drink water. There are two types of discoloration cups on the market:
1. Changing color cups when put into hot water(the most common), as the name implies, will start to change color when it encounters hot water with a temperature above 40 degrees, showing the printed pattern.
2. Changing color cups when put into cold water (currently less), that is, it can change color when encountering water, of course, it is low temperature instead of hot water!
In fact, the principle of discoloration cup is the same whether it is thermal or cold, but the temperature-sensitive materials are different! The color changing cup cannot change color without its unique structure. The color-changing cup is composed of an outer cup and an inner cup which are coaxially arranged. A sandwich cavity filled with a thermosensitive color-changing volatile liquid is provided between the bottom ends of the two cups. The outer wall of the inner cup is engraved with the layer. Intracavity art graphics channel. After the drinking cup is poured into hot water, the heat-sensitive liquid in the interlayer cavity will produce a color change and escape to the inner cup graphic channel, so that the wall of the cup displays an artistic pattern, which makes people get beauty and artistic enjoyment.
Therefore, the discoloration of the color changing cup lies in this heat-sensitive coating structure, and the color changing cup is completed inside the cup wall, which is a pure natural physical reaction. It is non-toxic, harmless and pollution-free fun plaything. Because the temperature-sensitive materials used are printed on the cup body, the materials used are imported high-quality heat-sensitive materials, which can withstand high temperatures of 320 degrees Celsius, non-toxic, lead-free, and chromium-free, and can meet the European Food FDA standards.
At the same time, the heat-sensitive material is completely isolated in the inner layer of the cup, and does not contact the beverage in the cup, and it will not cause pollution. It is completely a closed space, and the heat-sensitive material cannot run out, so it can be used unlimited times. Due to technological breakthroughs, the scope of the current color change cups is constantly expanding: black, red, line color, green, blue, brown, purple, light blue, light yellow, light green, light red, light purple, including dot effect , Can be designed as the surface layer of the color changing cup. But no matter what the current technical level is, the black matte color cup is the mainstream, no matter from the mask effect, the color effect or the black color cup technology is more mature, the effect is the best!
