Why is metal silver coated inside the thermos bottle liner?
1. The function of applying metallic silver to the gallbladder The main purpose of coating metal silver inside the thermos bottle is to improve the insulation effect. The insulation principle of a thermos bottle is achieved through the vacuum layer inside the gallbladder and the double-layer glass body, and the coating of metallic silver can […]
The difference between a good insulated cup and a regular insulated cup
1. Insulation time Good insulated cups are made of double-layer glass or stainless steel material, and their insulation time is longer than ordinary insulated cups, which can reach 4-10 hours or more. The insulation time of ordinary insulated cups generally does not exceed 3 hours, while some low-quality insulated cups may only have a insulation […]
Is the inner wall of the thermos cup frosted or mirrored better
1. Thermal insulation effect The frosted inner wall and mirror surface of the thermos have little effect on insulation. The core of insulation is double-layer vacuum, not the smoothness of the inner wall. The difference between frosted and mirrored surfaces has almost no effect on the insulation time. Of course, if there are obvious quality […]
Should we choose seamless or seamless thermos cups
Choosing seamless insulated cups can provide better insulation, but insulated cups with seams are easier to clean. 1. Advantages of seamless insulated cups Seamless insulated cups are less prone to water leakage and have better insulation effects. Due to the absence of gaps, there are no air gaps inside the bottle, which can slow down […]
Maintenance methods for thermos cups
