Stainless steel vacuum flask:
The stainless steel vacuum flask is made of double-layer stainless steel inside and outside. The inner tank and the outer shell are combined by welding technology, and then the air in the interlayer between the inner tank and the outer shell is extracted by vacuum technology to achieve the effect of vacuum insulation.
Generally speaking, the thinner the cup material, the longer the holding time. However, the cup body is easily damaged and deformed, which affects the service life; measures such as coating the outer layer of the vacuum cup with metal film and copper plating can also increase the degree of heat preservation; large-capacity, small-diameter vacuum cups have a longer heat preservation time, on the contrary, small capacity vacuum cups , The large-diameter vacuum insulation cup has a short holding time; the service life of the vacuum cup also depends on the cleaning of the inner layer of the cup and the time of vacuuming, and the most important thing is the structure of the vacuum furnace.
