When aluminum tin and vinegar are put together or soaked for a long time, aluminum salt will be produced, which will react with gastric acid to produce aluminum chloride (AlCl3). It is easy to produce carcinogens that are harmful to people.
Vinegar is an organic acid, which reacts with aluminum foil (tin foil) to produce aluminum salt, and aluminum salt reacts with gastric acid to produce aluminum chloride (AlCl3). It is easy to produce carcinogens that are harmful to people. If fish is wrapped in tin foil for barbecue, don't wrap lemon and other acidic fruits together for barbecue. Because tin foil paper belongs to metal, when metal and acidic substances are mixed and baked, chemical reactions will occur, which will easily produce carcinogens that are harmful to people.
Matters needing attention in the use of tin pots:
There are many kinds of small solder pots, which can be divided into mica insulation heating type and ceramic heating tube type according to the insulation form of heating elements. The temperature of mica insulated heating solder pot is below 400℃, and the components with low requirements are generally mica insulated heating solder pot; The temperature of ceramic heating solder pot is 400 ~ 500℃, which is generally used for rapid tin plating and welding of inductance coil, transformer, speaker voice coil, enameled wire and other connecting wires.
(1) After the solder pot is heated, tin plating or welding can only be carried out after the internal solder is completely melted.
(2) Unplug the power cord when the soldering pot is not used temporarily to avoid fire.
(3) The solder pot should be kept until the solder in it cools down, so as to avoid scalding.
(4) When using the solder pot, it is necessary to prevent the power cord from touching the surface of the solder pot, otherwise it will damage the insulation layer of the power cord, expose the metal wire and cause an electric shock accident.
