How to measure the insulation effect of double glass cups


The appearance of double-layer glass cups is almost double-layered. Many people generally like double-layered glasses when they choose cups, because double-layered glasses have better thermal insulation effect than single-layered glasses. Friends who need to drink warm water will use double-layered glasses. Layer the cup, so the hot water will cool down more slowly. Whether the thermal insulation effect of the cup is good or not, you can know by measuring. So how do you measure the thermal insulation effect of the glass before the user uses it?

1. Look at the shape: check whether the inner liner of the heat preservation is the same as the polishing on the outside, whether it is very uniform inside and outside, and there is no uneven place, and then see if there are any parts that are damaged or scratched If you have these problems, you should choose another thermos cup, because it is not suitable for a defective double-layer glass to be given to others as a gift.

2. Look at the quality of the material: if the quality is not good, this cup will not be used for a long time, and people will also affect the health of the human body when they drink water. It is recommended that you buy a double-layer glass, which is beautiful and durable. It's very healthy, and you won't worry about chemical residues or odors like plastic cups.

3. Check whether the production process of the mouth of the cup is meticulous: this is a relatively small detail, and some people will not notice it when choosing it, but generally speaking, it often reflects the quality of a gift mug. If this place is not done well, it will feel awkward when drinking water.

4. Look at the tightness: whether the mouth of the cup matches the body of the cup when it is closed. If it does not match, it is likely to cause problems such as water leakage during use, which will cause trouble to the user.

The thermal insulation effect of the double-layer glass cup can be measured by the above method, and the double-layer glass cup with good thermal insulation effect can also be selected according to the above method. If it meets the requirements, you can use a double-layered cup to hold warm water, so that there will be no problem of the water cooling down too quickly. Especially in winter, it is more applicable.
