The thermos flask is able to keep warm, this principle of heat preservation is in fact and home with the Thermos bottle insulation principle is consistent. The inner gall of the water bottle is a double-layer structure, and the careful person who buys the new liner notices that there is a raised small "tip" at the bottom. "Once the tip is broken, the water bottle is not warm." "This is often a" truth "that has been summed up by experienced mothers themselves. In fact, the water bottle insulation is indeed closely related to this structure.
Zhejiang Yongkang-Cup industry Co., Ltd., specializing in the production of Thermos Cups series products, focus on quality, has a wealth of production experience, now tell you, the Thermos insulation, its secret lies in ' vacuum break heat ' technology. The original, the Thermos flask and the same is a double-layer hollow structure, the inner and outer tube are made of stainless steel, different is the Thermos Cup in the middle of the air, in the glass sealed before sealing will be placed in the bottom of the cup of carbon particles, through 500 degrees of high temperature so that the carbon particles are fully burned, so that the hollow part of the air is depleted, to achieve almost complete vacuum effect. As we all know, the heat transfer is required by the medium, and for heat transfer in three ways, in which thermal radiation can be carried out in a vacuum. Therefore, in order to further enhance thermal insulation effect, manufacturers will be in the inner tube outer wall plating a layer of copper or aluminum, forming a smooth reflective surface, the cup tube emitted from the heat reflected into the cup. Then the same can be explained, household thermos inside the base of the bottom of the "sharp tip" once broken, the middle vacuum effect is lost, it can not be insulated, and liner silver plating and the inside of the tube plating copper or aluminum principle is the same.
