Judgment Criteria of Thermal Insulation Effect of Vacuum Water Bottle
Many buyer friends will ask a question when they buy vacuum water bottle products. How long does the insulation time of your vacuum water bottle? In fact, this problem is ambiguous in a sense. Why?
As we all know, the temperature of the best vacuum water bottle will drop slowly with time after pouring hot water. For example, after pouring hot water, the initial temperature will be 98 ℃; after 6 hours, the temperature will drop to 75 ℃, and after 8 hours, the temperature will drop to 68 ℃.
For people who drink water, 75 and 68 degrees centigrade belong to the category of "hot" temperature sensation, that is to say, holding for 6 hours or holding for 8 hours is the insulation time. It can be seen that this answer is not very scientific and accurate, and it is also more misleading to consumers.
