The Heat Preservation Principle Of Double-layer Stainless Steel Cup

1, the closed structure of the cup body

The cup body of the thermos cup adopts a double-layer structure, and the vacuum of the cup bladder and the cup body can block the heat transfer. Moreover, whether the sealing performance of the thermos cup is good also plays a very important role in the insulation effect. The better the sealing, the more difficult it is to transfer heat, which makes the heat preservation effect better.

2, double-layer stainless steel vacuum structure

Vacuum does not transfer heat, which is equivalent to cutting off the heat transfer medium. The higher the vacuum degree, the better the heat preservation effect. The vacuuming technology is divided into two types: tail vacuum and tailless vacuum. Now most vacuum cup manufacturers use tailless vacuum because this technology is more advanced.

3, the inner tank is plated with copper or silver

The inner tank is plated with copper or silver, which can effectively form a layer of heat insulation net on the inner tank of the vacuum flask, so that the copper plating can reflect heat radiation and effectively reduce the heat loss through radiation.
