How to Judge the Insulation Effect of the Vacuum Flask?
With the improvement of living standards, people began to pay attention to health preservation, and more and more people bought thermos cups. Many people think that the heavier the thermos cup, the better the insulation effect. However, it is not!
In fact, the criterion for judging the thermal insulation effect of a vacuum flask is not measured by its weight, but depends on other factors. The material of the thermos cup is one of the criteria for judging the insulation effect. The insulation effect of a vacuum flask with a good material is much better than that of a vacuum flask with a poor material. Just like the 304 stainless steel vacuum flask can keep heat for 12 hours, the 201 stainless steel vacuum flask can only keep 6 hours.
The insulation effect depends on its manufacturing process. The insulation effect of the vacuum insulation cup is much better than that of the ordinary insulation cup. The manufacturing process of vacuum insulation cups can be divided into tailed vacuum and tailless vacuum. Although the thermal insulation effect of the tailless vacuum cup is better than that of the tailless vacuum, the forming rate of the vacuum cup of the tailless vacuum process is lower.
The above two points can be used as factors to judge the insulation effect of the vacuum flask, and can also be used as a reference standard for purchasing a vacuum flask. Of course, the insulation effect of the vacuum flask will also be related to environmental factors.
