A thermos cup is something everyone will use in their daily life, especially in cold weather. Because of the strong insulation function, the thermos cup is deeply loved by everyone. Many people put some things in the thermos cup for convenience, but some things are not suitable for directly put in the thermos cup. What should we pay attention to when using stainless steel thermos?
Stainless steel insulated bottle is made of inner and outer layers of stainless steel, using welding technology to combine the liner and shell together, and then use vacuum technology to pull out the air in the liner and shell of the interlayer to keep vacuum insulation. Stainless steel insulated bottle is divided into ordinary thermos cup (after pouring the boiled water, the heat preservation time is generally less than three hours), vacuum thermos cup (through vacuuming process, the boiled water can be kept warm for more than 8 hours).
Stainless steel insulated bottle is not directly with an acidic liquid, such as lemon juice, carbonated drinks. The thermos is made of stainless steel. The melting point of stainless steel is higher, and the thermos cup will not release undesirable substances because of high temperatures. But stainless steel is the most afraid of strong acid, if a long time to store acidic liquid, may cause damage to the liner, affect the thermal insulation effect of stainless steel insulated bottle. Carbonated drinks can also cause a change in air pressure that makes it difficult to open the cork.
Stainless steel thermos bottles should not be used to hold fruit juice, milk drinks, a long time of high temperature will destroy nutrients. At the same time, it is also easy to cause a large number of bacteria breeding in high temperatures for these kinds of drinks. It may not only lose nutrients but also cause diarrhoea, abdominal pain and other phenomena, which will affect health.
Stainless steel insulated bottles should not be used to make tea. The good thermal insulation effect will make the tea-soaked for a long time in a state of high temperature and constant temperature. Long-term soaking will not only destroy a large number of nutrients in the tea but also affect the taste.
Stainless steel insulated bottles should not be used to hold Chinese traditional medicine. Some people like to put the Traditional Chinese Medicine (TCM) in stainless steel insulated bottle inside for convenience, However, it should be noted that there are a lot of acidic substances dissolved in the decocted Traditional Chinese Medicine, which are easy to react with some substances contained in the inner liner of the thermos cup and dissolve in the medicine juice, which will have adverse effects on the human body. At the same time, it is easy to make the medicinal materials deteriorate in a state of high temperature for a long time, and it will have adverse effects.
