Question 1: Is the silver-plated powder in the inner container of thermos harmful to human body? First of all, I want to tell you that there is no mercury or silver powder on the inner container of the current thermos, only a thin layer of aluminum. What everyone said above is an old imperial calendar. The water bottle liner was invented by British chemist Dewar in 1900. When the bottle liner was invented, it was indeed coated with mercury. Later, in order to reduce the cost, considering the toxicity of mercury, it was changed to silver plating. Later, in the last 20 or 20 years, with the progress of technology, all bottles were vacuum aluminized, which was both economical and safe. No one used any mercury or silver powder a long time ago. In addition, no matter what kind of coating, it is on the opposite side of the inner glass, and it will not contact with water, so it can be used safely.

Question 2: Is the metal in the inner container of the thermos toxic? It may be that the glass on the outer wall of the water bottle has peeled off, because the thermos bottle is double-layered, so it should not be a heat insulation coating. It may be that the glass on the outer wall of the thermos bottle has fallen off for a long time, which is not a big problem, but it is always uncomfortable to drink strange things that you don't know. I suggest you change a container. Personally, I suggest you change it every six months, which will be more reassuring. The inner container of the kettle is plated with silver. Theoretically, water is harmless to human body.

Question 3: Is it poisonous if the inner container of thermos bottle is broken? The inner side of the inner container of the thermos bottle in contact with water does not contain mercury. If the inner container of the thermos bottle breaks, causing the mercury coating on the outer layer to enter the water, the main component is mercury, which is toxic and must be discarded immediately.

Question 4: Is the metal in the thermos container toxic? As long as it does not directly enter the human body, it is not toxic.

Question 5: Is the metal in the inner container of the thermos toxic? It may be that the glass on the outer wall of the water bottle has peeled off, because the thermos bottle is double-layered, so it should not be a heat insulation coating. It may be that the glass on the outer wall of the thermos bottle has fallen off for a long time, which is not a big problem, but it is always uncomfortable to drink strange things that you don't know. I suggest you change a container. Personally, I suggest you change it every six months, which will be more reassuring. The inside of the kettle is silver plated. According to theory, water is harmless to human body.

Question 6: Is it harmful to drink the metal on the inner wall of thermos bottle? The silvery white on the inner wall of the bottle is a thin layer of silver, and now it is mostly aluminized. The container of thermos bottle is double-layered, and the interlayer is plated, which is a silver mirror reaction. Silver nitrate reacts with reducing substances (formaldehyde or glucose) to precipitate silver on the glass surface, forming a mirror surface. Will not fall off. Harmless. Vacuuming the liner can reduce conduction heat dissipation, and coating the liner with reflective film can reduce radiation heat dissipation.

Question 7: Is the thermos container not toxic to metals? The thermos container is made of glass and is non-toxic.

Question 8: How many pieces of coating have dropped from the inner container of the thermos? Will it be toxic? The inner container has no coating, only the scale produced by long-term use. As long as you don't drink, you'll be fine.
