What kind of water cup is a “poisonous water cup”?

When writing this article, I remembered that I seemed to have written a similar article in 2020, but I couldn't find it after reading it through. http://www.umbottle.com/ProductsDetail-VB-10012.htmlMaybe there was something wrong with my memory, or maybe I wanted to share some such content with everyone at the time, but maybe I didn't have enough ability and materials at the time, so I put it aside when writing this article today.

"Poisonous water cup"? What is a "poisonous water cup"? Are there any friends who think that the editor's description of "poisonous water cup" is a bit alarmist or exaggerated? http://www.umbottle.com/ProductsDetail-VB-10012.htmlThe editor can responsibly say that it is not at all. The editor is willing to use his many years of experience in the industry to guarantee it.

If I were to talk about the "stories" of some morally corrupt factories producing water cups, probably 90% or even more of my friends would find it unbelievable. http://www.umbottle.com/ProductsDetail-VB-10012.htmlAt the same time, for the sake of most conscientious companies in the water cup industry, I will only talk about what kind of water cup is a "toxic water cup" today?

Water cups have long become an indispensable item in our daily lives. We cannot do without water cups when eating, sleeping, washing and working. http://www.umbottle.com/ProductsDetail-VB-10012.htmlTherefore, water cups have become an important part of our lives and are closely related to our health. This is also the motivation for the editor to write this article.

First of all, how to define "toxic water cups"? The "toxic water cups" mentioned here refer to those that contain harmful substances or germs. When buying a water cup, friends must understand what materials are used in the production of the water cup. Now that the Internet is so developed, you can immediately find out the properties of materials that you don't understand by searching on your mobile phone. http://www.umbottle.com/ProductsDetail-VB-10012.htmlFor example, if the water cup you buy is used for daily drinking hot water, then many water cups made of plastic materials cannot be used as hot water cups, such as AS, PS, PED, PC, etc. These materials will release bisphenolamine once the hot water exceeds 70℃. When will bisphenolamine be released?

The editor has already introduced it in detail in the previous article, so I will not repeat it here. Friends who want to know, please read the previous article or search online. When buying a stainless steel water cup, be sure to understand whether it is food-grade stainless steel.http://www.umbottle.com/ProductsDetail-VB-10012.html 304 and 316 stainless steel are food-grade stainless steel. Stainless steel of other materials cannot be used as materials for the production of stainless steel water cups. 201 stainless steel is not food-grade stainless steel. Metal elements such as nickel and chromium in the material will also release harmful substances due to long-term high water temperature. The consequences of using these cups range from dizziness and nausea to serious damage to the cardiovascular system, especially for infants and the elderly. Of course, these symptoms will not appear immediately after one use, but are usually caused by long-term use. However, once serious problems occur, it is difficult to improve them through medical treatment.

Secondly, another situation of "toxic water cups" is that the production environment of the enterprise is bad, and the water cups are not well kept, which causes the water cups to be polluted by the environment after production, and are packaged without cleaning and disinfection and put on the market today. http://www.umbottle.com/ProductsDetail-VB-10012.htmlSuch water cups appear on the market every year. I can say responsibly that no matter what material the water cups are made of, if strict bacterial flora tests are carried out, there will be water cups that exceed the standard on the market. Relatively speaking, the possibility of this happening to glass water cups and some water cups with expensive materials and high production costs is low.

Finally, the editor extends the definition of "poisonous water cup". Some water cups with poor workmanship, serious design flaws, and even the potential to cause harm to people during use can also be called "poisonous water cups."
