Even some illegal businesses in order to reduce production costs, the production of counterfeit, low-quality products to fake the stainless steel thermos bottle, and some even use some unqualified, toxic stainless steel material to produce stainless steel thermos bottle, which will cause harm to people's health.
Here we remind consumers that if they want to choose high-quality stainless steel thermos bottle, they can follow the following four standards:
1. Whether the surface polishing of the inner tank and the outer tank of the stainless steel thermos bottle is uniform;
2. Observe whether the workmanship of the stainless steel thermos bottle is fine and whether the welding interface is flat;
3. Add boiling water for two or three minutes, and feel whether the outer wall of the stainless steel thermos bottle is hot;
4. Pay attention to the product packaging information. The materials used by different brands are different. Generally, 304 stainless steel or austenitic stainless steel within the medical grade range can be used, or they can be identified by magnets. 304 stainless steel is non-magnetic.
