How to safely use stainless steel thermos cups in daily life? With the advent of winter, many consumers have purchased stainless steel thermos cups. Some people not only use it to hold boiling water, but also use it to make tea or coffee, etc. Are these things in stainless steel vacuum flasks harmful to our human body? About these, let’s learn how to use stainless steel vacuum flasks correctly.
The stainless steel vacuum flask is made of double-layer stainless steel inside and outside. The inner tank and the outer shell are combined by welding technology, and then the air in the interlayer between the inner tank and the outer shell is extracted by vacuum technology to achieve the effect of vacuum insulation. It has many advantages such as good thermal insulation performance, light weight, anti-rupture, anti-corrosion, anti-extrusion, good heat resistance and rapid change performance, and easy to use.
Moreover, the stainless steel vacuum flask is made of food-grade 304 stainless steel to ensure that the amount of heavy metals dissolved in the vacuum flask containing water does not exceed the standard, including lead.
At the same time, the inner cover of the regular stainless steel thermos cup is made of PC material. This PC material is tasteless and will not deform when boiled in boiling water. The rubber ring is made of silica gel, which is also non-toxic.
The stainless steel thermos cups purchased through regular channels are not toxic for drinking boiled water, and will not pose a hazard to people’s healthy drinking water. But be careful not to choose too cheap stainless steel, because the cost of 304 stainless steel determines the quality.
It is not poisonous to choose a regular stainless steel thermos cup to drink water, but if the stainless steel thermos cup is not filled with boiling water, but tea or milk, soy milk and other substances, everyone has to drink it with caution.
