What is the general material of the inner liner of the vacuum flask? -Alice factory

November 17, 2021

1. The glass liner is coated with a thin layer of aluminum.

2. Stainless steel inner tank. The outer surface of the stainless steel inner tank has a silver-plated layer. Because there is a silver-plated layer on the outer surface of the inner pot of the stainless steel vacuum flask, it can effectively reduce the heat radiation between the inside of the cup and the outside, and increase the holding time.

3. The coatings are all on the reverse side of the inner glass and will not be in contact with water under normal circumstances. Identification of the insulation of the inner tank: This is the main technical indicator of the vacuum flask. After being filled with boiling water, turn the bottle stopper or lid clockwise, and then touch the surface and bottom of the cup body with your hand after 2 to 3 minutes. The obvious warming phenomenon on the upper part of the cup indicates that the inner tank has lost its vacuum degree and cannot achieve a good heat preservation effect.
