For the service life of the cup, the service life here is pan-meaning, and various factors can be counted such as beating, corrosion resistance and so on.
Ceramic mugs have the longest service life in safe use, no impact and no corrosion in the use environment. Ceramic cups are fired at high temperature and the structure is compact and stable. Currently, known ceramic cups can be used for more than 100 years everywhere. It can still be used without leaving the structure intact.
When fighting or wrestling, the service life of the silicone cup is the longest, because the silicone has great ductility, so it can be deformed when accidentally falling or accidentally being hit by a hard object, absorbing force to ensure the integrity of the structure. But if it is a sharp object impact, stainless steel cup life is the longest. After testing by professional organizations, the service life of stainless steel cups is on average about 15 years, and the biggest problem in this time is that stainless steel materials will cause corrosion and oxidation because of the use of habits and different liquids.
So what about the service life of stainless steel cups and plastic cups?
Stainless steel cups are harder than plastic cups, but not as good as plastic cups in corrosion resistance; Plastic cups are light, but not as good as stainless steel cups in the service life of repeated use; Stainless steel cup has good temperature resistance, but the plastic cup is used in a wider environment, if the overall life is compared, the service life of stainless steel cup is still greater than that of plastic cup.
Ceramic tableware is divided into glaze color, glaze color and underglaze color three, according to the production process is different, in fact, ceramic tableware also has a service life.
In general, glaze color ceramic tableware, the pattern on the surface of the tableware is easy to wear and fall off, the service life is generally about eight to ten years, but the specific length of time should be determined according to your use.
Glaze color and glaze color are fired at high temperatures, and the pattern of glaze color tableware is integrated with the glaze, and the pattern of underglaze color tableware is under the glaze, which will not wear and fall off. These two kinds of ceramic meals are not said to have a service life, generally as long as there is no damage, they can be used without limit.
There are also some low-temperature fired ceramic tableware, which is prone to explosion when it encounters high temperature, so it has a service life, generally about three to five years.
How often should I change the ceramic tableware?
The replacement time of ceramic tableware is not unified, as long as we are in use, do a good job of cleaning and sterilization, generally do not need to be replaced, but if the ceramic tableware appears in the following situations, it is to remind us to replace in time.
The ceramic tableware is cracked
Many ceramic tableware have very beautiful patterns, but these patterns will use dyes, which can contain heavy metal lead. Therefore, when the ceramic tableware cracks, heavy metal lead may precipitate from the cracks, enter the food, and bring harm to our health, even if the tableware does not leak, it can no longer be used, and it needs to be replaced in time.
Ceramic tableware appears discolored and worn
When the glazed ceramic tableware appears to fade and wear, it can no longer be used, and it should be replaced with a new one in time. These colors may contain heavy metals, and the color will be mixed into the food and enter our body, which is not conducive to health.
The ceramic tableware appears to be deporcelain
When ceramic tableware is deporcelain, it can no longer be used, deporcelain indicates that the tableware structure has changed, there is a problem, it must not be used again, at this time, it must be replaced in time.
In short, when we usually use ceramic tableware, we must pay more attention to it, clean it in time after each use, and dry it, and do not use hard things such as steel balls to wash the tableware, which is easy to wear the tableware. As long as the use of good habits, ceramic tableware can be used for a long time, but if the ceramic tableware appears cracks, wear and discoloration and porcelain, it should be replaced in time.
