Stainless steel insulated water bottle is made of inner and outer double-layer stainless steel. It combines inner and outer shell by welding technology, and then extracts air from the interlayer between inner and outer shell by vacuum technology to achieve the effect of vacuum insulation. It has many advantages, such as good heat preservation, light weight, anti-cracking, anti-corrosion, anti-extrusion, heat resistance and rapid change, convenient use and so on. And the stainless steel insulated water bottle uses 304 stainless steel of food grade as material to ensure that the dissolved amount of heavy metals in the water-filled insulating cup does not exceed the standard, including lead. At the same time, the inner cover of the regular stainless steel insulated water bottle is made of PC material, which boils in boiling water without taste and deformation. Aprons are made of non-toxic food-grade silicone.
So, do stainless steel insulated water bottles produce toxic substances? It is not toxic to drink boiled water by using stainless steel insulated water bottles purchased through regular channels, and it will not harm human health. But be careful not to choose too cheap stainless steel insulated water bottles, because 304 stainless steel cost determines the quality.
But if we use stainless steel insulated water bottle to fill acid and alkaline substances, it will produce toxic substances, which is harmful to our health.
It is not toxic to drink water from a regular stainless steel insulated water bottle, but if the stainless steel insulated water bottle contains not boiling water, but tea or milk, soybean milk and other substances, we should drink with caution. Tea contains a lot of tannic acid, theophylline and aromatic oil. It also contains a variety of vitamins. If tea is brewed in an insulated water bottle, the tea will be immersed in high temperature water for a long time, which will greatly reduce the original nutritional value of the tea, make the tea tasteless and bitter, and increase the harmful substances in the tea. If milk is packed in a thermos bottle, the bacteria can reproduce every 20 minutes and spoil the milk in 3-4 hours. In addition, the constant temperature in the insulated water bottle can destroy vitamins in milk, etc.
