Three new uses of zinc oxide

1. Prevent discoloration of the coating film

As the zinc oxide process becomes more and more sophisticated, in addition to its original function, it has been recently discovered that this upgraded zinc oxide can effectively prevent discoloration of the coating film. In addition to being used as cosmetics, this zinc oxide can also be used as a raw material for automotive paint, furniture building materials, inks, and oil paints, as well as an anti-aging agent for rubber and plastics. What's more, it can be coated on transparent film of food packaging and covered on polyethylene film. The effect of this application can prevent ultraviolet rays, and at the same time can extend the time of food and ensure the quality of food. With the continuous improvement of technology, new uses of zinc oxide will gradually be developed.

2. Thermometer

The color of zinc oxide itself is white. As the temperature increases, it will gradually change from white to light yellow. When the temperature increases, zinc oxide will change from light yellow to lemon yellow. When the temperature slowly decreases, the color will change from  The shades fade back to white. This is the change in the thermometer.

3. Semiconductor field

Zinc oxide can emit light. Zinc oxide has a large energy band gap and exciton binding energy, high transparency, and excellent room temperature luminescence performance. It is used in liquid crystal displays, thin film transistors, light-emitting diodes and other products in the semiconductor field. In addition, micro-particle zinc oxide as a nano material has also begun to play a role in related fields.
