What is the insulation material and principle of Lekou mug?

1. The insulation material of Luck mug is two layers of stainless steel. The principle is the same as that of a thermos, which is double-layered, and then the air inside is pumped out and turned into a vacuum state to prevent the loss of heat energy.

2. The thermos cup is generally a water container made of ceramic or stainless steel with a vacuum layer. The top is covered and sealed tightly. Vacuum insulation layer can delay the heat dissipation of water and other liquids to achieve the purpose of insulation. The thermos cup is developed from the thermos bottle. The principle of heat preservation is the same as that of thermos bottles, except that people make bottles into cups for convenience. There are three ways to spread heat: radiation, convection and transmission. The silver liner in the thermos cup can reflect the radiation of hot water, and the vacuum between the liner and the cup can block the heat transfer, while the bottle which is not easy to transfer heat can prevent the heat convection. Now the principle of magnetized water is also applied to thermos bottles, that is, magnets are added to the bottom and cap of the bottle to magnetize the water. It is said that magnetized water has magical effects.
