Why does the water cup have such a serious peeling phenomenon?

The editor has nothing to do today, log on to Amazon to find out which are the hottest water cups in the current C-end market? Add your knowledge.When I saw a well-known brand water bottle, I was attracted by the buyer's comments.In fact, what really attracted the editor was not what the buyer said, but the photo of the water bottle that the buyer showed after using it for a while.The editor made a screenshot of this photo, which is the picture in the article.I believe you are as surprised as I am.Under what kind of usage environment can such a serious paint peeling phenomenon occur on the surface of a water bottle?

Based on my work experience, I will analyze the reasons for this phenomenon.But with such a serious phenomenon in the picture, it doesn't look like it was caused by improper use.A joke unless the water cup has been used by consumers for a long time, from childhood to adulthood, and then to have children.

The editor analyzes the production quality problems that cause this phenomenon.The first could be a problem with the paint material.If the material is not up to standard, even if it is produced according to the standard operation requirements, such a phenomenon may occur.(But in the experience of Editor, although I have experienced the problem of paint materials failing to pass the test, I have never seen such a serious problem.)

Every stainless steel water bottle must be polished and cleaned before painting.If you do not go through this step, the adhesion of the paint will be seriously reduced after spraying, and there is a possibility of such a serious phenomenon in the picture.

After the stainless steel water cup is sprayed with paint, it must be baked under strict temperature and time control, so as to increase the adhesion of the paint.Insufficient or too high temperature will cause quality problems in the product.The temperature is not high, the adhesion is low, and this phenomenon does occur after the finished product is used for a period of time.Although the temperature is too high, it will not have a significant impact on the paint adhesion, but the high temperature will directly change the color of the finished paint.

If the product in the picture happens occasionally, the editor's analysis is not caused by the first and third operations, and the second is the most likely.

After buying a water bottle, if you are worried that the paint will peel off, you can find a pencil or wooden object and tap the surface of the water bottle lightly.But don't use a lot of strength, after all, the merchant will not return the cup after the pit appears.If there is a real possibility of paint peeling, such a light tap can also be detected, and the most obvious one is the appearance of fine cracks on the surface.When tapping, it is best to hit the position close to the mouth of the cup.
