Can’t the stainless steel vacuum flask really contain carbonated drinks?

Answer: It is true that the stainless steel vacuum flask cannot be filled with carbonated drinks.

Stainless steel has no anti-corrosion properties for acidic beverages. Long-term use of carbonated beverages in stainless steel water cups will not only damage the inner wall of the water cup, but also cause harm to the human body.

At the same time, due to the good airtightness of the stainless steel water cup and the expanding gas released by carbonated beverages, once the gas pressure is too high, coupled with the damage of the acid to the inner wall of the water cup, the water cup will explode seriously. This is a real case. The media once reported an accident in which a stainless steel insulated water cup filled with carbonated beverages caused a water cup to explode. The explosion of the water cup also caused injuries to users.

Carbonated beverages are suitable for the use of plastic water cups. This material has strong ductility. When the pressure is too high, the plastic water cup will deform to respond. The stainless steel material is different, it is obviously weaker than the plastic material in ductility.

If the stainless steel water cup contains corrosive acid and alkali substances, the inner wall needs to be coated with a special ceramic, so as to avoid the damage of acid and alkali to stainless steel.
