What harm does the oxidation of aluminum products do to the human body 40

This is also called the electroplating industry, especially the pre-treatment of strong acid, strong alkali and high temperature environment, especially the yellow smoke after nitric acid heating is more harmful to the body.

If you are engaged in this industry for half a year, there is no problem, and in the oxidation process, as long as the exhaust is good, there is no harm to the body.

Electroplating is the process of using the principle of electrolysis to coat a thin layer of other metals or alloys on some metal surfaces, and it is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other materials, so as to prevent metal oxidation (such as rust), improve wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhance aesthetics. Many coins also have electroplated outer layers.

Alumina is not toxic, usually the pot we use for cooking is made of aluminum, aluminum reacts with oxygen in the air and becomes alumina, this layer of alumina adheres to the surface of the pot, which will prevent the aluminum inside from continuing to react with oxygen.

How to maintain the iron pot.

After washing the pot, you should dry the water in time, you can wipe it with a dry cloth, and you can also dry it, which can avoid the pot from rusting.

If you don't use the pot for a long time, you can take the pork to grease or fry the oil, wash it with water and dry it, and then hang it in a cool and ventilated place for preservation.

Don't use an iron pot to boil water, it's best to smear some oil on it after boiling water, so as to prevent the iron pot from rusting.

When the human body ingests too much aluminum, it will indeed cause aluminum poisoning, which can lead to nausea and dementia.

Aluminum utensils can be used, but pay attention to the method. Generally, aluminum pots look gray and not as bright as other metals at all, this is because the aluminum is oxidized. This oxide film is very strong and dense, corrosion-resistant, and sufficient to isolate aluminum from contact with food.

And manufacturers usually artificially thicken this oxide film to make the product safer. Therefore, aluminum containers produced by regular manufacturers can be used with confidence.

In the process of material oxidation, the alkali washing, pickling and light used for pretreatment are all strong acid and strong alkali. In the production process, these solutions will form acid mist or alkali mist in the surrounding air due to volatilization, heating and other reasons, and the damage to the human respiratory tract, especially the respiratory mucosa, will be relatively large after breathing into the human body. Some aluminum oxidation light solution contains hydrofluoric acid, which is toxic.

Aluminum is a silvery-white light metal that forms an oxide film in moist air that prevents metal corrosion. So why does aluminum oxidize?

When aluminum encounters oxygen, it undergoes a chemical reaction to form aluminum oxide on the surface of the aluminum product. Although aluminum itself has strong corrosion resistance, after a long period of oxidation, it will slowly destroy the corrosion resistance and wear resistance of aluminum, and the life of aluminum products will be reduced. In addition, aluminum's oxide film is thinner, and it has high porosity and adsorption properties, so it is easily contaminated.

In addition, aluminum is also sensitive to acidic substances, and if it encounters acidic substances, the surface oxide layer of aluminum will be destroyed. Therefore, it is best to seal the treatment, and it is necessary to artificially thicken the oxide film of aluminum to enhance the corrosion resistance and wear resistance of aluminum alloy products.
