Why must the water cup with ceramic paint inside pass the 100 grid test and the dishwasher test?

The source of the technology and craftsmanship of spraying ceramics in the water cup and the pots and pans sprayed with Teflon, the idea comes from the European and American markets.The purpose is to avoid the direct contact of the stainless steel with the coffee, which will lead to the change of the coffee taste.

Insulated ceramic mugs first entered the market in early 2018.Once the water cup was launched in the European and American markets, it was adopted by many water cup brands.However, the temperature quickly cooled after only half a year of listing, which once led to a large number of quality water cups being returned by the market.Until 2020, the water cups sprayed with ceramics will be disgusted by many businesses in the global market.

With the continuous improvement of production, the continuous improvement of technology, and the continuous deepening of water cup testing.The new internal spray ceramic paint interview in the second half of 2020 is very different from the previous products.Why were early water glasses returned?How good is the technology now? This is exactly what the editor wants to talk about why the water cup with ceramic paint inside must pass the 100 grid test and the dishwasher test？

In the early days, the ceramic paint materials purchased by the water cup factory did not have a unified standard, and the performance of different materials produced by material manufacturers in different batches was unstable.Manufacturers are not proficient in technology during production, which causes various problems in the finished product, such as different baking temperatures, and the color of ceramic paint will change greatly.

The material properties are not up to standard, causing the baked coating to be soft, and a slightly harder object will have obvious scratches when scratched.The most serious thing is that most factories at that time did not realize that the adhesion of ceramic paint directly sprayed on the stainless steel water cup would be poor.Only after sandblasting the area to be sprayed before spraying, the adhesion of the baked coating will be higher.

But even now in 2022, there are still many manufacturers who know how to produce to meet the market requirements, so there is a 100 grid test.The purpose of the 100 grid test is to detect the adhesion of the coating.Why take a dishwasher test?At present, there are still many ceramic paint brands on the market.

Here, the editor has to advertise our company. For the technology of spraying ceramic paint inside the water cup, our company has rich experience and has exclusively developed a variety of technologies. Currently, the water cups with ceramic paint sprayed inside are sold all over the world.
