不锈钢保温瓶,象玻璃保温瓶一样,其瓶胆也由内、外两层组成,但其内胆、外胆、外壳、瓶盖等均由不锈钢制造。内、外胆之间,保持高真空,隔热保温性能达到了玻璃保温瓶的水平,以达到国家标准所规定的保温能力。 Stainless steel thermos flasks, like glass thermos flasks, consist of two layers, inner and outer, but their liners, outer bladders, shells, and bottle caps are made of stainless steel. Between the inner and outer gallbladder, the high vacuum is maintained, and the heat insulation and heat insulation performance reaches the level of the glass thermos bottle, so as to meet the heat preservation capacity required by the national standard.
