Why can a newly purchased stainless steel thermos only keep the temperature for 3 months? (Part 2)

Hello everyone, I am here to share again. Yesterday I talked about the main reason why the insulation function of a newly purchased thermos cup only lasts for 3 months due to improper production management by the manufacturer. http://www.umbottle.com/en/ProductsDetail-IR-10067.htmlNow I will continue to share. Today I will talk about the reasons why the insulation function of a newly purchased thermos cup only lasts for 3 months due to improper use by consumers after purchase.

Store properly to avoid falling from heights

Yesterday we talked about the structure of stainless steel thermos. The double-layer stainless steel is welded together through high-temperature welding. The depth of the welding position is very shallow. Coupled with the subsequent polishing and other processing, the welding position is made even shallower, but it cannot be seen from the appearance. http://www.umbottle.com/en/ProductsDetail-IR-10067.htmlIf it is not stored properly and causes the water cup to fall from a height, the effect of the center of gravity can easily cause multiple bumps at the mouth or bottom of the cup after it falls. Most thermos choose the double-layer connection welding position, which is the mouth and bottom of the cup. Once the mouth and bottom of the cup are deformed and the weld is broken, the insulation function of the thermos will gradually be lost.

Store in a dry place to avoid mold

Many consumers tighten the lid of the thermos cup after using it, regardless of whether there is still water inside. They think that even if there is water, it doesn’t matter, after all, it is made of stainless steel and will not rust. At the same time, the environment in which it is placed is not particular, such as in the kitchen or storage room. First of all, after using the water cup, if it is not used for a long time, the water inside and outside the water cup needs to be wiped clean. http://www.umbottle.com/en/ProductsDetail-IR-10067.htmlIf there is water or other beverages inside, it will become moldy if not used for a long time. Mold is highly corrosive, especially for thermos cups with welding technology in the inner liner. Mold corrosion starts from the welding line, which will cause vacuum to break and the insulation function to be lost in severe cases. The external environment is the same, especially in some places with serious oil pollution and high salt content, the external corrosion of the water cup will also cause vacuum to break.

The accessories are too old and the water cup is not sealed tightly.

Excessive aging of accessories mainly refers to the silicone seal rings that play a sealing role in the thermos. The reason for excessive aging may be that the thermos is used for carbonated drinks and milk drinks for a long time, and it is not thoroughly cleaned after use, causing the silicone seal ring to become sticky and loose. http://www.umbottle.com/en/ProductsDetail-IR-10067.htmlThe sealing performance of the aging seal ring is reduced, and the water temperature dissipates faster, which makes the insulation performance of the thermos reduced.
