Why does 316 stainless steel water cup with boiling water taste

You use the magnet to try to see if it is stainless steel, and if it will absorb it, it is stainless iron. Boil the water to remove the odor, put the thermos cup into tea and boil for 5 minutes, and then wash it and air it to eliminate the odor. The stainless steel insulation cup is made of double-layer stainless steel inside and outside, and the inner liner and the outer shell are combined by welding technology, and then the air in the interlayer of the inner liner and the outer shell is extracted by vacuum technology to achieve the effect of vacuum insulation. Stainless steel thermos cup is divided into ordinary thermos cup, vacuum thermos cup In fact, vacuum thermos cup, the length of holding time depends on the structure of the cup body and the thickness of the cup material. Generally speaking, the thinner the cup material, the longer the holding time. But the cup body is easy to damage and deformation, affecting the service life; Measures such as metal film coating and copper plating on the inner liner of the vacuum cup can also increase the degree of heat preservation; Large capacity, small caliber vacuum cup holding time is longer, on the contrary, small capacity, large caliber vacuum cup holding time is shorter; The service life of the vacuum cup also depends on the cleaning and vacuuming time of the inner layer of the cup, and the most important is the structure of the vacuum furnace. The vacuum equipment used in the society has a vacuum exhaust platform and a vacuum brazing furnace, and there are about four types of two types. One is a vacuum exhaust bench with tail; Another type of brazing furnace. Brazing furnace type is divided into: single chamber, multi-chamber, increase pumping speed multi-chamber. Single furnace integral vacuum brazing furnace. The vacuum cycle time of the furnace is long, and if the home wants to improve the production efficiency and shorten the vacuum time, it will affect the service life of the cup. The service life of the cup is only about eight years. With tail vacuum cup exhaust platform and advantages: with tail exhaust that is a vacuum cup produced by the vacuum exhaust platform, the heating temperature is about 500 ° C when vacuuming, the shell of the vacuum cup is not easy to deform, but the copper welding is easy to leak, and special protection should be given to the semi-finished product processing. In addition, a large category is vacuum brazing furnace type, about divided into three types, did not expect it, usually we use vacuum insulated cup although in appearance and general thermos cup there is no difference, in the production process of vacuum insulated cup by general thermos cup is much more complicated, the technical difficulty is much higher. Therefore, the price of vacuum insulated cups is at least twice higher than that of general insulated cups.
