The vacuum insulation cup is generally a water container made of stainless steel and a vacuum layer. The top has a cover and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of the water and other liquids contained in it to achieve the purpose of heat preservation.
1. Cup body closed structure 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 transfer of heat. And whether the sealing performance of the thermos cup is good, it also plays a very important role in the insulation effect. The better the seal, the harder it is for heat to transfer, resulting in better insulation.
2. Double-layer stainless steel vacuum structure The vacuum does not transmit heat, which is equivalent to cutting off the heat conduction medium. The higher the vacuum degree, the better the thermal insulation effect. The vacuuming technology is divided into two types: tail vacuuming and tailless vacuuming. Now most vacuum cup manufacturers use tailless vacuuming because this technology is more advanced.
3. The inner tank is copper-plated or silver-plated. The inner tank is copper-plated or silver-plated, which can effectively form a layer of heat insulation net in the inner tank of the thermos, so that copper plating can effectively reduce the heat lost through radiation by reflecting heat radiation. .
