What if a stainless steel thermos bottle is not insulated?
The stainless steel insulation cup suddenly loses its insulation, which should be related to the product quality; If the product is within its shelf life, it can be replaced with the seller in a timely manner. Insulating cups are developed from thermos bottles, and the insulation principle is the same as thermos bottles, except that people make bottles into cups for convenience.
Simple identification method for vacuum insulation performance:
(1) Pour boiling water into a thermos cup and tighten the cork or lid clockwise for 2-3 minutes. Touch the outer surface of the cup body with your hand. If there is obvious warming on the cup body, it indicates that the product has lost its vacuum and cannot achieve good insulation effect. The exterior of the insulated cup is always cool.
(2) Check if the internal seal is tight. Check whether the screw plug and cup body fit properly, whether the cup cover rotates in and out freely, and whether there is water leakage. You can fill a glass of water and invert it for four to five minutes or vigorously shake it a few times to verify if there is a water leak.
Stainless steel insulation cups are mainly divided into: ordinary insulation cups (the insulation time after pouring boiling water is generally less than 3 hours), and vacuum insulation cups (through the vacuum process, the boiling water can be insulated for more than 8 hours).
