Stainless vacuum flask is a kind of alloy metal products. According to different uses, the trace metal elements contained in it will be different. Common metal elements are chromium, nickel, silicon, carbon, aluminum and so on. The stainless vacuum flask is mainly produced by the combination of internal and external double-layer stainless steel materials through vacuum technology. The vacuum structure of the stainless vacuum flask can effectively control the three heat transfer ways of heat conduction, heat convection and heat radiation to achieve the purpose of heat preservation, cold preservation and freshness. Therefore, it has three major functions of heat preservation, cold preservation and freshness, which is healthy, fashionable and environmentally-friendly.
The stainless vacuum flask can keep the temperature of the water in the container for a long time, which is convenient for users to enjoy hot drinks at different times and spaces, which is conducive to improving people's quality of life; the stainless steel thermal flask uses stainless steel as the raw material and will not produce hazardous substances, and the insulation of drinking water avoids the damage to water quality caused by repeated boiling of water.
With the continuous changes of consumers' aesthetic tastes and the continuous progress of product manufacturing technology, many vacuum flask manufacturers have integrated various fashion elements into the design of stainless steel vacuum flasks, and the product styles are becoming more diverse and exquisite, satisfying consumers' demand for fashion.
Promoting the use of stainless vacuum flasks can effectively reduce environmental pollution caused by the waste of disposable plastic containers and paper cups, and reduce the consumption of oil, wood, water and other natural resources in the production of plastic containers and paper cups. At the same time, the stainless steel vacuum flask can keep heat for a long time, which reduces the electric energy consumption caused by repeated heating. The waste of disposable bottled water is serious. Using stainless vacuum flasks to replace disposable plastic containers can also effectively reduce resource waste.
