What Is An Insulated Water Bottle?
Vacuum insulated water bottle is generally a water container made of ceramic or stainless steel with a vacuum layer. It has a cover on the top and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of water and other liquids installed inside to achieve the purpose of heat preservation. The insulated water bottle is developed from the thermos kettle. The principle of heat preservation is the same as that of the thermos kettle, but people make the bottle into a water bottle for convenience.
How Do Insulated Water Bottles Work?
The reason why the thermos cup can keep warm is mainly that the heat transfer is blocked after vacuuming. There are three ways of heat transfer: convection, conduction, and radiation, so even in a vacuum environment, heat can be transferred, but at a slower rate.
What Is The Best Insulated Water Bottle?
Insulated bottles are made of stainless steel material, and understanding the difference between stainless steel materials will help you choose a better water bottle. There are more than 150 types of stainless steel, each with different properties. According to NSF international standards, the stainless steel used in food equipment must be either 200, or 300 series.
