What are the problems with the water cup that has been used for a period of time that will not affect the use?

In the previous article, editor wrote what problems occurred in the water cup after using it for a period of time, which affected the use?Today, the editor will talk about what problems will occur after the water cup has been used for a period of time that does not affect the use?Some friends will have questions. Can the water cup be used even if there is a problem?Still not affected? Yes, don't worry, the editor will tell you all about it.

Taking the plastic water cup as an example, the plastic water cup just purchased is very high in terms of color and transparency.After using it for a period of time, you will find that the accessories in the white part begin to turn yellow, the transparency of the cup body also begins to decrease, and the color appears dull and foggy.

This kind of problem does not affect the use of the water cup.The white and yellowing phenomenon is caused by the oxidation of the material, and the cup body is no longer transparent partly because of the oxidation of the material.Another reason is caused by the friction of use and cleaning. This situation cannot be understood as the deterioration of the material, and it will not affect the use after normal cleaning.

Taking the stainless steel water cup as an example, some friends found that there was a sound in the water cup after using the thermos for a period of time.The faster the rhythm of shaking the water glass, the more intense and louder the sound becomes.They always feel that there is a small stone inside the water glass, but there is no way to get it out.Some friends think that the water cup is broken when they find such a situation, and will discard the water cup 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.

The editor mentioned in the previous article that 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.It is the getter that guarantees the effect of vacuuming. In production, some getters have some offsets due to their placement and the angle is not in place. Although they have played the role of auxiliary vacuuming, they may be closed after a period of use. Due to external force, there will be a phenomenon of falling off.

Even some water cups have this situation before they are put into storage. Of course, if such problems occur in production, the factory will not let such water cups out of the warehouse as good products.The factory where Editor is located will dispose of these water cups in-house every year. On the one hand, it can recover a certain cost, and on the other hand, it can also reduce carbon emissions.

There are also some included paint on the surface of the water cup, scratches, etc., which will not affect the continued use of the water cup.
