People usually say that the thermos water bottle refers to a water bottle composed of double-layer stainless steel or double-layer glass. In this article, we will explain the working principle of the stainless steel thermal insulation water bottle and how to realize the thermal insulation of the thermal insulation water bottle, hope to be able to help customers who wholesale insulated water bottles.
Stainless steel insulation is made of double-layer stainless steel by welding, that is, the water bottle is composed of a complete shell and a completed inner tank.
The middle of the two layers of stainless steel is hollow, which can prevent the heat of the liquid in the water bottle from losing through the thermal conductivity between the stainless steels. In order to increase the thermal insulation of the stainless steel liner, we generally have the following three general methods.

Increase the distance between
The first is to increase the spacing between two layers of stainless steel, which can greatly reduce the heat conduction speed of stainless steel to achieve the purpose of thermal insulation.
Add insulation
The second is to coat an insulating layer on the outer surface of the stainless steel liner, which will adhere to the outer surface of the stainless steel liner to prevent the water bottle from radiating heat.
Vacuum processing
The third is to vacuum the gap between the two water bottles, so that the gap between the two stainless steel water bottles is in a vacuum state. This can greatly block the conduction of heat.

The insulating water bottles produced by Auland can be treated as required by customers to enhance the thermal insulation performance of the water bottles. At the same time, we will test the vacuum performance of the water bottle during the production process, and the water bottle that fails the test will be picked out.
