1. Why does the stainless steel water cup make a sound?
Taking the stainless steel water cup as an example, some friends found that there was a noise in the water cup after using the thermos for a period of time. Take it out, some friends think that the water glass is broken when they find that the water glass is in such a situation, and will discard the water glass and replace it with a new one when they cannot get after-sales service. When this happens, we first judge whether the thermal insulation performance of the water cup has decreased. If the thermal insulation performance of the water cup has not changed, then even if there is a sound inside the water cup, it will not affect everyone’s continued use. There is a sound inside, like a small stone, because the getter inside the water cup falls off.
2. Why can stainless steel water cups be kept warm?
The reason why the stainless steel water cup is kept warm is that it can have a good heat insulation effect through the vacuuming process.
