The color change cup is also called the magic cup. Injects hot water or cold water in the cup, the cup will change color changes.The color -changing cup is divided into thermal deformation cup and cold color transformer cup. They are composed of two parts: outer cups and inner cups set by coaxial cups. They are set up between the bottom of the two cups., So that different colors or artistic patterns are displayed through temperature changes.Lets take a look at it together.
What is the working principle of the discoloration cup
The discoloration cup can be divided into three types: thermal change and cold color change, and encountering water discoloration, and the discoloration of water has not yet been popularized.When the temperature of the thermal transformer cup is above 40 ° C, the color changes, and the temperature of the cold -changing cup changes when the color is below 20 ° C.
The reason why the discoloration cup is inseparable from its unique structure is composed of two parts of the outer cup and inner cup set by the coaxial axis. It is set up between the bottom of the two cups.The outer wall of the inner cup is engraved with an art graphics channel with the inner cavity in the layer.After the water cup is poured into the hot water, the thermal liquid in the mezzanine cavity will generate color changes and be promoted in the graphic channel of the inner cup, so that the cup wall shows the artistic pattern, so that people can get aesthetic and artistic enjoyment.
The discoloration of the discoloration cup is mainly due to this thermal coating structure. Because thermal material is completely isolated in the inner layer of the cup, it will not contact the drink in the cup, so it will not cause pollution.The color change of the cup in the internal color of the cup is a pure natural physical response. It is non -toxic, harmless, pollution -free, and can be used unlimitedly.
How is the discolored cup made?
1. Direct printing
Refers to printing directly on the cup with a roller. This technology has technical difficulty. Generally, the general factories can only print one or three colors. If you encounter the high requirements of the set, the color is incomparable.There are up to 20 colors without positioning. This technology is only suitable for small batches, and the efficiency is very low.It can only be printed with a face, and the effect of printing photos is difficult.
2, water transfer
It is printed on the water transfer paper with a printing machine. This can print a rich color and can also be produced in large quantities. However, the environmental requirements are relatively high.After the water transfer paper is placed in the water, the pattern is separated from the paper, and the pattern is transferred to the cup to bake the finished product.The Christmas color change cup below belongs to this process.
3. Hot transfer
The printing process of transferring water is basically the same, and the printing paper that is printed is reposted on the cup through the machine heating and pressing.When the water transferring cup is produced, the reposting pattern needs to rely on the manual operation of the person, and the thermal transfer depends on the automation processing of the machine.Printing production line is the strongest manifestation of competitive strength.
Precautions for use of color change cups
1. It is strictly forbidden to put in high -temperature places such as microwave oven/disinfection cabinets.
2. It should not be exposed in strong light.
3. It should not be soaked in water.
4. Do not scrape/rub the surface image of the cup, otherwise it will cause the cup body image to fall off.
