The paint on the surface of the new water cup began to crack and fall off soon after using it. What is the cause? Is there a remedy?

In my spare time, I will crawl the Internet to read posts, and I also like to read the e-commerce purchase evaluations of my peers to see what aspects of people are more concerned about when buying water cups? Is it the thermal insulation effect of the water cup? Or the function of the water cup? Or the appearance?

After reading more, the editor found that the paint on the surface of many new water cups has not been used for a long time, and the paint on the surface of the water cup has begun to crack and start to fall off.Because the replacement conditions set by e-commerce platform shopping are generally up to 15 days, some consumers may purchase and use it just beyond this time, and they cannot return the goods.There is no way but to express your bad mood through comments. So what is the cause of cracking or falling off? Can it be remedied?

At present, the surface of water cups of various materials on the market is sprayed with paint (except the ceramic surface is colored glaze), whether it is plastic, stainless steel, glass, etc.In fact, these water cups will also have cracked or peeled paint on the surface. The main reason is the factory process control.

Professionally, the corresponding spray paint for each material is also different, including high temperature paint and low temperature paint.Once there is a deviation in the material of the water cup corresponding to the paint, it will definitely appear chapped or fall off.In addition, the production process is also very strict in the control of the spraying process, which includes the thickness of the spraying, the baking time and the baking temperature.The editor has seen many water cups on the market with uneven paint spraying at a glance. Due to the uneven spraying, it is necessary to control the paint color on the surface of the water cup without major changes.

Therefore, the effect of spraying thin areas is generally accommodated, which will result in insufficient baking temperature or time in thick areas.There is also a stainless steel water cup as an example, be sure to do enough cleaning on the surface of the water cup before spraying.Usually, ultrasonic cleaning is used to clean the stains on the surface of the water cup, especially the oily places, otherwise the paint will fall off first after spraying on any unclean places.

Is there a remedy?From a professional point of view, there is really no remedy, because neither the requirements for paint materials nor the requirements of the production environment can be achieved and satisfied by an ordinary consumer.But the editor has also seen many friends through the graying of their own artistic cells, some repainting and creating in the chapped place, and some sticking some unique patterns on the detached place.The effect of this is really good, not only blocking the flaws but also making the water cup unique and unique.

Finally, a warm reminder from the editor: after purchasing a new water cup, first wipe the surface of the water cup with warm water, you can repeat it several times to see the surface effect after wiping, if a new water cup is used for less than a month, it will If the paint is chapped, it can usually be seen by wiping, but do not use hard items such as steel balls for wiping. In this way, the merchant will not return or exchange the product.
