the characteristics of vacuum insulation cup
In fact, the length of the heat preservation time of the vacuum thermos depends on the structure of the cup body and the thickness of the cup material. 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. The vacuum equipment used in the society for vacuuming vacuum flasks includes vacuum exhaust table and vacuum brazing furnace, and there are about two types and four types. One type is benchtop with tail vacuum exhaust; the other type is brazing furnace type. The brazing furnace type is further divided into: single chamber, multi-chamber, and multi-chamber with increased pumping speed.
