Winter is approaching. At this time, many people will start to buy glasses. Because the temperature is about to drop, the hot boiling water will quickly cool down. Drinking cold water in a cold weather is very bad for the body. Therefore, there will be many people who want to keep their water warm. Generally speaking, the better insulation performance is to count glasses, but there are also many brands of glasses. Which brand of glass is good? How to choose The glass is a very big problem.
We have to look at the structure of the thermos first. Generally, this kind of thermos is composed of an inner liner and an outer liner, so we have to see if the two are the same. If they are the same, then it is The quality is better, if it is not the same, for example, there is some roughness, then the production process is not rigorous enough.
It also depends on whether the part of the cup mouth is relatively smooth, whether the whole cup mouth is the same without unevenness, because this is related to the comfort when drinking water. If the internal sealing of the insulated glass is not enough, or If the piston on the mouth of the cup does not match the whole cup body, you cannot choose this brand of cup.
You can also look at the mouth of each cup. Generally, if the quality is better, the mouth must be relatively round. If it is not round, it must be caused by the immature production process. There is a relatively simple judgment method, then Just twist off the lid of the cup and see if the lid of the cup matches the interface of the entire cup body.
The important thing about the glass vacuum flask is the heat preservation characteristics. It depends on which brand of glass is good. The very important point is to look at the heat preservation characteristics. You can pour boiling water into it. After a period of time, touch the body of the cup to see if it is hot, if it is not hot. It means that the characteristics of heat preservation are not very good, and it can be returned with proof of amount.
