3 key points of choosing thermos insulated water bottle.
Whether it's going out for activities or going to work, carrying a thermos insulated water bottle with you can quench your thirst immediately and reduce the use of disposable water bottles. However, when using a thermos insulated water bottle, you should not only pay attention to it before purchase and use, but also pay attention to the cleaning and maintenance after use.
Key points in proper use of thermos insulated water bottle:
Material selection. With the rising awareness of environmental protection, the use of thermos insulated water bottle is becoming more and more popular. However, when selecting the thermos insulated water bottle, it is necessary to choose the thermos insulated water bottle material that meets the hygienic standard, so as to avoid metal poisoning. According to the proportion of synthetic metals, stainless steel has different numbers, which can be divided into 200, 300 and 400 series. Because of the high content of nickel and chromium, the 300 series has been recognized as the best series for corrosion resistance and rust prevention. If you want to choose tableware, thermos insulated water bottle, etc., 304 and 316 in 300 series can be selected. Most of them contain 18% chromium and 8-10% nickel, but the latter will add. The thermos insulated water bottle is mainly made of 304 stainless steel based on the consideration of cost and price.
When choosing the thermos insulated water bottle, you can refer to the label of the outer package, the trusted brand and the SGS inspection certificate.
According to the Internet rumor, stainless steel thermos insulated water bottle can't hold milk, tea, coffee and other acid-base drinks, or it will cause corrosion of the thermos insulated water bottle and lead to metal poisoning. As long as the thermos insulated water bottle that meets the inspection standard is used, all the edible drinks will not cause corrosion to the thermos insulated water bottle and cause harm to the human body. Unless the liquid with strong pH (such as pH value less than 2 and greater than 10) is deliberately soaked in the thermos insulated water bottle for several days, the metal substance may be released.
In addition, in order to reduce the weight and increase the tightness of the thermos insulated water bottle, plastic, silicone and other materials will be used for the cup cover. Therefore, the plastic materials of food grade hygiene standard can be selected when purchasing, so as to avoid the problem of "plasticizer" and "bisphenol a".
There are many manufacturers for sports, summer launched thermos insulated water bottle, in fact, and the general thermos insulated water bottle insulation effect is not different, but in order to facilitate rapid replenishment of water, the water outlet will be relatively large, so it is not recommended to pack liquid with too high temperature to avoid scalding. If equipped with plastic straw, also pay attention to the heat resistance temperature marked on the product.
Most people need to pay more attention to the problem of bacteria breeding when they use the thermos insulated water bottle. For example, most people often take the thermos insulated water bottle to hold drinks such as milk and coffee. Although the thermos insulated water bottle can slow down the temperature loss, when the user repeatedly opens the thermos insulated water bottle for drinking, it will accelerate the temperature loss, and let the drink come into contact with the bacteria in the mouth, which will make the drink deteriorate and breed bacteria (15-3 ℃) Third degree bacteria are most likely to reproduce). In addition, the thermos insulated water bottle should be cleaned as soon as possible after use, otherwise it is easy to have scale and let bacteria grow. Although it is convenient to drink directly from the mouth of the thermos insulated water bottle, if you want to reduce the possibility of bacteria breeding, it is suggested that the water in the thermos insulated water bottle can be poured into the cup for drinking.
