Principles of Vacuum Thermos Bottle

Vacuum thermos bottle is a water container typically made of ceramic or stainless steel plus vacuum layer and the top cover is tightly sealed, the vacuum heat-insulating layer can be mounted on the liquid such as water inside the delaying the purpose of cooling, in order to achieve thermal insulation. Vacuum thermos bottle is evolved from the insulation principle thermos, just for the convenience of the bottle is made of a cup. Thermal spreads in three ways: radiation, convection, and passed. The cup silver gall cup and the body of the vacuum cup can be reflected radiation, the hot water can block the transfer of heat, and the heat is not easy to pass the bottle to prevent thermal convection. Thermos (or insulation cup), its wall is constituted by a double-glazing, and the middle of the double-glazed is vacuum thermos bottle, and its cover is generally with poor thermal conductivity and this is true of the middle of the vacuum flask double glass gall, it is evacuated between the two layers.

Maintenance of the Stainless Steel Vacuum Flask

Do not pour carbonated drinks, due to the internal pressure increases may lead to the superstructure prolapsed of the thermal mug; Do not use it to contains salt, otherwise it will become thinner, have steel balls, and do not contain grinding silver powder and use detergent. It may cause scratches or rust; Do not place near the fire source; Do not use the dishwasher and microwave; Do not place drinks for a long time. (Recommended save time not more than 6 hours); Do not store water and special drinks for long periods. Drinks containing some other objects may cause the cup discoloration and other problems; Do not drop or apply impact force, since it will reduce the insulation effect.

Industrial Development of Thermal Mug

Stainless steel vacuum flask industry in China began in the early 1990s, after 10 years of development, the annual sales volume reached 2.5 billion RMB, the annual export is about $ 220 million; and the production enterprises of a certain size is about 500 more than become a big country and a major exporter of the world production of stainless steel insulated cup. Stainless steel vacuum flask has a very important significance to promote healthy development of China vacuum flask the industry and it is also an important way to improve product quality, as well as a good way to prevent stainless steel vacuum thermos (pot) industry from great loss, and to improve the international competitiveness of the important initiatives.
