In winter, a cup of water will cool down after a while, so whether at home or in the office, everyone should have a stainless vacuum flask. Nowadays, stainless vacuum flasks are standard equipment for those who pay special attention to health. They will hold a stainless vacuum flask wherever they go. The stainless vacuum flask is very convenient to use, especially in the cold winter, but not all liquids are suitable for putting in the vacuum flask.
Matters needing attention in the stainless vacuum flask:
1. The stainless vacuum flask should not be filled with carbonated beverages, as we all know that carbonated beverages are gaseous drinks. When the thermal flask is bumped, a large amount of carbonated beverage gas emerges. When the good thermal flask has a high sealing performance, more gas generated by the filled carbonated beverage liquid will easily cause the thermal flask to burst.
2. The stainless vacuum flask is not suitable for acidic drinks. Acidic substances will chemically react with stainless steel, which will cause the drinks to deteriorate and taste. Moreover, the stainless steel of the vacuum flask will also be oxidized and rust, which shortens the service life of the vacuum flask.
3. The stainless vacuum flask should not be filled with hot milk. The hot milk in the vacuum flask will allow the microorganisms in the milk to rapidly multiply at a suitable temperature, leading to corruption and easily causing diarrhea and abdominal pain. The acidic substances in milk will also chemically react with the inner wall of the thermos, which will affect human health.
4. The stainless vacuum flask is not suitable for storing Chinese medicine, because a large amount of acidic substances are dissolved in the Chinese medicine, which will easily react with the chemical substances contained in the inner wall of the vacuum flask, and dissolve into the decoction, which will have adverse effects on the human body.
