Does a stainless steel water cup have a shelf life?
Hello everyone, "Dong Dong Talks About Cups" is here. Yesterday, the editor shared about whether plastic water cups have a shelf life. Immediately, some friends asked whether stainless steel water cups and glass water cups have a shelf life. http://www.zhanyict.com/en/ProductsDetail-VB-10479.htmlOkay, today the editor will continue to share with you whether stainless steel water cups and glass water cups have a shelf life. If you want to know whether plastic water cups have a shelf life, please read the editor's previous articles. If you like the editor's sharing, please follow the editor and give the article a little red heart.
Unlike the previous article, I can now tell you for sure that there is no shelf life requirement for stainless steel and glass water cups. Why? Because the molecular structure of stainless steel and the sodium calcium and high borosilicate (medium borosilicate and low borosilicate) materials used in the production of glass water cups are stable and compact, and both have good antibacterial properties. http://www.zhanyict.com/en/ProductsDetail-VB-10479.htmlAlthough corrosion, oxidation and rust may occur in some special environments, this situation is not universal. At the same time, the production materials of these two water cups have very high industry standards, so both stainless steel and glass water cups are very durable, so neither administrative agencies nor national authoritative testing agencies have specified the shelf life of stainless steel and glass water cups.
Although there is no shelf life requirement for stainless steel water cups and glass water cups, they still have a service life. Taking stainless steel thermos cups as an example, the service life includes the integrity of various functions and the safety of various accessories. Functions include heat preservation function, sealing function, and the opening and closing function of the cup lid. http://www.zhanyict.com/en/ProductsDetail-VB-10479.htmlAccording to data analysis by authoritative institutions, the average heat preservation function of stainless steel thermos cups currently sold on the market can maintain the market for about 3 years. There are many reasons for the decline of heat preservation function, and the main reason is still caused by the production process.
The sealing function of the water cup is also very important. Currently, various types of thermos cups mainly rely on sealing rings made of silicone. http://www.zhanyict.com/en/ProductsDetail-VB-10479.htmlThe service life of silicone sealing rings is usually about 3 years. The closer to the life span, the more aging the silicone sealing ring will appear. The aging manifestation is generally the silicone becoming sticky or the silicone starting to fall off. Once this situation is found, the sealing ring needs to be replaced as soon as possible.
Accessory safety refers to whether other accessories that complete the function of the water cup have aging, damage, or deformation, which may affect the safe use of consumers. For example, many thermos cup lids are made of plastic. http://www.zhanyict.com/en/ProductsDetail-VB-10479.htmlPlastic not only has a service life, but even if the plastic material used to produce the water cup lid has strong wear resistance, plastic accessories will still wear out after long-term use. The opening and closing, bite, and tensile strength of the worn plastic accessories are affected. Will these effects cause potential dangers during use? Similarly, some hardware accessories also have service life issues. All these accessories determine the integrity of the water cup's function.
Although stainless steel water cups and glass water cups do not require a shelf life, http://www.zhanyict.com/en/ProductsDetail-VB-10479.htmlhaving a certain understanding of the service life of some accessory materials will also help us use water cups more safely and healthily in daily life.
