What is the difference between electrolysis, ceramic paint coating and enamel in thermos cups? Which is the best? (one)

At present, the inner surface of thermos cups on the market generally has these processes, polishing, electrolysis, spraying ceramic coating and enamel technology. What's the difference between these? Which of these crafts is the safest and harmless to the body?

This question is summed up by the editor in the recent period of contact with customers. Because there are many customers who are confused about the production cost and safety of these processes, most of these customers are encountered when developing new products.

Internal polishing is easier to understand. The inside of the water cup is polished and smoothed by the polishing machine without burrs and no welding tumors, which ensures the safe use of the water cup and the interior is relatively more beautiful. There are still many customers who only require polishing inside the finished water cup. The markets targeted by these customers have more requirements for products, and the products are as authentic and simple as possible, so that everyone will feel more at ease when using them, and at the same time, the price will not rise due to the addition of too many processes to the water cup.

Inner liner electrolysis, the popularity of liner electrolysis process is mainly based on the final visual appearance of the inner liner, which is also more beautiful. The purpose of electrolysis is to make the inner surface of the water cup smoother. At present, there are basically two electrolysis methods on the market, one is to carry out sandblasting company treatment after electrolysis, and the other is to mirror electrolysis effect. The effects of the two processes are different, and the production costs are also different.

But the effect is the same. After electrolysis, it is not that a new coating is added to the water cup, and the surface of the inner tank of the water cup is still in a stainless steel state. The purpose of inner wall polishing and inner wall electrolysis is to make the inner wall smoother, and both processes are also in direct contact of stainless steel with water and beverages. Stainless steel materials are safe to use as long as they are food grade.
