Why are thermos cups and insulated lunch boxes so popular
1. Technological upgrade: from “insulation” to “intelligent insulation” (1) Material Revolution: Stainless steel vacuum insulation technology (such as 304/316 medical grade stainless steel) has increased the insulation time from 6 hours to 24 hours and reduced weight by 30%. (2) Function expansion: Some products have added temperature display (accurate to ± 1 ℃), magnetic charging […]
Method for replacing batteries with a temperature insulated cup
1. Understand the types of insulated cup batteries The battery with a temperature insulated cup is generally a CR2032 flat silver battery, and some brands also use other types of batteries, but the replacement method is basically the same. 2. Preparation before replacing the battery (1) Prepare batteries: Purchase batteries of the same model. (2) […]
Do you carry a thermos or a travel mug when traveling
If you need to store temperature for a long time during the journey, it’s better to bring a thermos. If more emphasis is placed on portability and lightness, then the portable cup is a better choice. 1. Insulated cup Insulated cups are usually used to maintain the temperature of beverages and can keep them warm […]
The difference between a sealed and seamless inner liner of a thermos cup
1. Process difference: Welding vs. Integrated Forming (1) Seam inner liner: It is formed by welding metal sheets after curling, and the seams are usually laser or high-frequency welded. The advantage is that the production cost is low (about 30% lower than seamless inner liner), but the weld seam is prone to residual metal shavings […]
Reasons for the heating of the thermos cup lid and whether it affects the insulation effect
The heating of the thermos lid does not necessarily indicate poor insulation effect, but may be related to factors such as the sealing of the lid and the material used. 1. The reason for the heating of the thermos cup lid There may be several reasons for the heating of the thermos cup lid, including: […]
Exploring the Metal Materials Used for the Inner Wall of Insulated Bottles
1. Core structure and function of thermos bottle Insulated bottles achieve insulation function with their unique vacuum layer design, reducing heat loss during temperature transfer. In order to further enhance the insulation effect, the inner wall of the thermos bottle is usually made of a layer of metal material with superior thermal conductivity. 2. Common […]
