Can children use stainless steel thermos cups with imitation ceramic interior?

A: Not recommended

Why is it not recommended? Let me tell you. The origin of the imitation ceramic technology is to be able to replace ceramic water cups, and then have the same effect as ceramic in terms of use experience or function. http://www.zhanyict.com/en/ProductsDetail-VB-10121.htmlThe reason why the imitation ceramic technology is made is that ceramic water cups are heavy, fragile and not heat-insulating, so the stainless steel water cups make up for the shortcomings of ceramic water cups after using the imitation ceramic technology.

Imitation ceramic technology is not difficult to understand literally. "Imitation" means it is not real ceramic, so imitation cannot be 100% ceramic. http://www.zhanyict.com/en/ProductsDetail-VB-10121.htmlImitation ceramic technology has only been popularized for a short time, only a few years. Although the technology has been continuously improved and the inspection standards have been continuously improved, there are still many problems with imitation ceramic technology.

Imitation ceramic technology is actually the spraying process, but this type of "paint" is relatively special, and is closer to the "glaze" material in ceramic production. The texture is hard and the final effect is smooth. http://www.zhanyict.com/en/ProductsDetail-VB-10121.htmlHowever, since the current restrictions on the composition standards of ceramic paint are relatively broad, and the inspection standards are based on adults, some ingredients, although partially acceptable to adults, are still excessive for children.

Some factories even artificially change the proportion of some ingredients to make the ceramic paint present a better visual effect and enhance the hardness. There are cases that show that the lead content of some manufacturers' imitation ceramic stainless steel water cups exceeds the standard. http://www.zhanyict.com/en/ProductsDetail-VB-10121.htmlI believe many friends know that the subsequent lead poisoning of children directly affects the brain development, so from the perspective of the material composition content, it is not recommended for children to use imitation ceramic stainless steel thermos cups.

In addition, the editor has shared in the previous article some problems that still exist in the current imitation ceramic production process. http://www.zhanyict.com/en/ProductsDetail-VB-10121.htmlOne of them is the problem of adhesion between ceramic paint and the inner wall of stainless steel. This is a problem that has existed since the popularization of imitation ceramic technology.

The production process of imitation ceramic technology is as follows. First, the inner wall of the stainless steel water cup must be sandblasted to make the inner wall rough, and then cleaned and dried. http://www.zhanyict.com/en/ProductsDetail-VB-10121.htmlAfter drying, the inner wall ceramic paint is sprayed. The inner wall spraying of ceramic paint usually adopts the inverted spraying method, which can avoid the dripping and deposition of ceramic paint at the bottom and can also make the ceramic paint flow back and leave it from the mouth of the cup, so that the internal spraying is more uniform.

The editor is going to talk about why the ceramic paint has insufficient adhesion to the inner wall. First of all, when sandblasting, since the inner wall of the water cup is not a straight tube up and down structure, some positions cannot be completely sandblasted, or the sandblasting is not thorough. Secondly, inverted spraying usually causes incomplete spraying at the lower cup shoulder, and the ceramic paint flows downward in liquid form, and the lower the position, the thicker the paint thickness will be. http://www.zhanyict.com/en/ProductsDetail-VB-10121.htmlAfter high-temperature baking, the positions where the sandblasting is not thorough and the positions where the paint is too thick will peel off or break. This is why many consumers buy stainless steel water cups with imitation ceramic technology and find that the ceramic paint falls off after using them for a period of time.

In addition, due to the hardness of ceramic paint, the harder it is, the more brittle it will be. The stainless steel thermos cup with imitation ceramic technology can be tested by a drop test. After several drops, the ceramic paint with poor adhesion on the inner wall will fall off. http://www.zhanyict.com/en/ProductsDetail-VB-10121.htmlChildren are very likely to drop the cup due to their physical strength and activeness. This situation is very serious for children. Once children accidentally eat the detached ceramic coating during use, it may be fatal. Therefore, the editor recommends that parents try not to let children use stainless steel thermos cups with imitation ceramic technology.
