Clever selection of Stainless Steel vacuum flask Four steps Choose a safe product When purchasing stainless steel thermos cups, in addition to paying attention to performance indicators such as inner tank material, thermal insulation performance and impact resistance, you should also scientifically select high-quality stainless steel thermos cups through the four steps of smelling, seeing, touching, and testing. First Smell A high-quality stainless steel thermos should have no peculiar smell, or the smell is slightly easy to disperse. If after opening the lid, the smell is strong and persists for a long time, it means that there is a risk in the use of the product, which should be avoided and replaced in time. Second look Check whether the label has information such as product name, specification, heat preservation energy efficiency, name of the producer and (or) distributor; whether the material type and composition of the stainless steel cup body are clearly marked (need to comply with the "National Food Safety Standard for food contact products) Requirements for stainless steel materials in "Metal Materials and Products"), or expressed by our country's standard grades or unified digital codes, not only vague information such as "high-quality stainless steel" and "high-grade stainless steel"; whether to indicate the material of plastic parts (sealed The cover should be made of polypropylene material, which is safe and heat-resistant). Check whether the surface of the product is uniform in color, whether there are cracks or gaps, whether the printed text and patterns are clear and complete, and whether the electroplated parts are exposed, peeled, rusted, etc. Three touches The surface of the inner and outer tanks of high-quality stainless steel thermos cups should be polished uniformly, without bruises, scratches or burrs; the mouth of the cup and the weld should be smooth and clean without burrs. Four tests Inject boiling water into the stainless steel thermos cup, tighten the cup lid, after 2-3 minutes, you can feel whether there is a significant temperature rise by holding it in your hand, and test the heat preservation performance; pour boiling water, tighten the cup lid, and after 4-5 minutes, turn it upside down, The sealing performance can be tested by the presence or absence of leakage. In addition, the spin performance and the convenience of disassembly, washing and reinstallation can also be tested by opening and closing the cup lid and disassembling various parts several times.
