Principle of Thermal Insulation Bottle

1. Closed Structure of Bottle Body

The body of the thermos cup is double-layer structure, and the vacuum of the gallbladder and the body can block the transfer of heat. And whether the sealing performance of the thermos cup is good or not, also plays a very important role in the insulation effect. The better the seal, the harder it is for heat to be transferred, resulting in better insulation.
 

2. The Inner Liner is Plated with Copper or Silver

The inner copper or silver plating can effectively form a layer of heat insulation net in the inner chamber of the thermos cup, so that the copper plating can effectively reduce the heat lost through the radiation by reflecting the thermal radiation.
 

3. Double Stainless Steel Vacuum Structure

Vacuum does not transfer heat, it is equivalent to cutting off the heat conduction medium. The higher the degree of vacuum, the better the insulation effect. The vacuum technology is divided into two kinds: tail vacuum and tailless vacuum.

 

1. The technology is different: "tail vacuum", also known as tubular vacuum, is a traditional vacuum process, the use of "pressure sealing technology", this technical measures in the micro is not completely sealed; "Tailless vacuum" is the most advanced vacuum technology at home and abroad, that is, the vacuum cup in the vacuum environment, by computer control to complete the process of pumping, sealing welding, cooling, the use of "fusing sealing technology" can ensure long-term air leakage.


2. Different equipment: "tailless vacuum" thermos cup equipment is a large equipment, high degree of automation, high level of product quality, so the cost is expensive, and the management and use of technology is complex, not easy to master, single product power consumption is several times higher than "tail-vacuum", so at present only a few enterprises in China fully master and use this technology, Yongkang Henruy Company is one of them. However, this technology has high quality and better performance, which will become the mainstream vacuum technology in the manufacturing industry of thermos cup.


3. Higher vacuum and longer holding time: Because tailless vacuum thermos cup is vacuumized and sealed under the condition of nearly 1000℃, the vacuum degree and tail vacuum are the same at this time, when the product returns to room temperature, the vacuum degree is much higher than "tail vacuum".


4. Large effective capacity: Since there is no mouse tail like "tail vacuum", there is no need to set up a "tail chamber", so the effective space is large. Compared with "tailless vacuum" products with the same appearance volume, the effective space inside the tailless vacuum thermos cup is much larger.
