Vacuum flask of the bladder wall metal gullet harmful
That is silver, h and hydrochloric acid in gastric juice can't response, should it's nothing... Die. Ancient has swallowed the gold and silver. But it was much, so drop dead.
The silver on the inside is a thin layer of silver, now mostly use aluminum coating. Inside of the vacuum flask is double, is within the interlayer of plating, is silver mirror reaction. With silver nitrate and reducing substances (formaldehyde or glucose) reaction, make silver precipitation on glass surface and form a mirror. Don't fall off. No harm. The tank into a vacuum plating is to reduce its conduction, bladder on reflective membrane is to reduce radiation heat dissipation.
Don't. Now the hot water bottle, vacuum flask, use double deck glass inside, the inner and outer glass or aluminum silver plated material (similar to a mirror). Inside is through the silver mirror reaction (silver plated silver solution of Ag compounds by reduction of metallic silver chemical reaction, are attached to the container wall due to the generation of metallic silver, bright as a mirror, so called the silver mirror reaction), contains no poisonous mercury (mercury), will not cause harm to human body.
