As soon as my skin touches iron, copper and other metals will rot, so help me figure it out

That's the phenomenon of metal allergies, I will too, as soon as I touch the metal body, it will be raised, and then it is rotten, so I don't wear anything with metal on my body, such as all kinds of trinkets: earrings, earrings, rings, etc., I can only wear gold, my mother said that I am rich and noble, hehe, the thief laughs at a :) but the buttons that cannot be avoided on the jeans can be wrapped with a piece of cloth, and it is OK to sew it, and the belt you try not to let it touch your **.

Close the kitchen door and look for clothes (old) to plug the opening.

Metal allergies can occur locally, causing allergic contact dermatitis or anaphylactic dermatitis. Therefore, once unexplained dermatitis occurs, it is necessary to go to a qualified hospital to determine what kind of metal is allergic to through the patch test of the metal, and then study the way through which the metal enters the body, if it can prevent re-entry, the allergic reaction will no longer occur. But this process is often very difficult to complete, and as a result, it is often not possible for a long time.

Therefore, you can only try to avoid contact with metal, or use topical ointment to alleviate it, if it is mild allergies, you can try to apply a layer of clear nail polish on the zipper to reduce direct contact between metal and ** to avoid.

It may be a metal allergy, it is best to see a doctor.

1 Don't wear clothes with zippers.

2 Take some immunosuppressive medications.

I bought some zippers that weren't metal, and I dismantled them and reinstalled them.

It should be caused by these heavy metals, first of all, the allergen must be banned, it is best not to do things there, those things are very harmful to **, these are harmful and toxic objects, and then you can use some skin care products to play a conditioning role, I used to be a little red, itchy, ** and dry, and then my sister's friend gave me the Kang Fuer anti-allergy cream she was using (my sister's friend is also a little allergic, but she only ** is relatively dry, It's also often reddened from time to time), I didn't think that there would be obvious effects the next day, at least the itchy feeling that made me hate to the bone was much better, and now I'm using the second set, **Not only is it good, but it's also slippery to the touch, and I'm so happy to go out??

Hope it helps!

It seems that there is no fundamental solution to metal allergies

Copper does not rust in dry air.

Yes, especially moist air (reactants have water, Cu rust also requires CO2).

Crystal Detox Detoxification Detoxification also has a significant effect on quickly removing and inhibiting toxin regeneration for toxins that hide deeply, latent and harmful toxins in the human body. **Itching, dryness, peeling, redness, stinging and other **allergy symptoms, itself shows that the body has accumulated a lot of metabolic toxins, coupled with the routine **process, it is inevitable to absorb toxins and hormones in the drug, these toxins not only cause damage to ** but also aggravate **allergy to allergens. It is different from the general detoxification method, it first adsorbs and phagosomes the toxins, and then gradually decomposes them, and gradually excretes them through the excretory system or sweat glands, completely removes blood toxins and eliminates the basis for the existence of allergies.

So as to say goodbye to facial allergies.

How to put it,.

Iron reacts with oxygen in the air to form iron oxide, which is called rust. The loose structure of the rust does not prevent further oxidation of the iron.

Copper reacts with oxygen and carbon dioxide in the air for a long time to form basic copper carbonate (patina), which is called copper rust...

Aluminum reacts with oxygen in the air to form alumina, but alumina is different from iron oxide, alumina is a dense oxide film that can protect the further oxidation of aluminum...

Aluminium reacts with oxygen in the air to form alumina, but unlike iron oxide, alumina is a dense oxide film that protects aluminium from further oxidation.

So it's wrong.

Obviously wrong, this still needs to be asked.

The determination of ferrous ions can never be determined by color.

Because many ions can appear green. For example, CR3+

And Cu is given in the question, and if there is not enough water, Cu2+ will also appear blue-green.

So, the answer is troublesome but correct.

It may be copper ions, and the concentrated copper chloride solution is also green.

In the solution of copper chloride, there are not only hydrated copper ions [Cu(H2O)4]2+, but also chloride ions Cl- combined with copper ions to form tetrachlorocopper complex ions [CuCl4]2-, which is yellow in color. According to the principle of optics, we know that the mixed color of blue and yellow is green, which is why our common general concentration of copper chloride solution is green. If we add water to the copper chloride solution, the concentration of chloride ions in the solution becomes smaller, and the hydrated copper ions increase relatively, and the solution mainly shows the color of hydrated copper ions (blue).

So the copper chloride dilute solution we see is generally blue.

Wine contains trace amounts of organic acids that react with metals to allow them to enter the wine as ions, which can seriously affect the taste of the wine...

In addition, in the wine process, the food additive sulfurous acid is often used, which will corrode the metal even more! This is mainly due to the fear of affecting the taste of the wine, and in addition, in GB T 15037, the wine has a strict limit on the amount of metal ions in it!

That's all I know. If there are others, I can also learn by the way.

It should be used to prevent contamination by miscellaneous bacteria, and if it comes into contact with it, it is easy to oxidize and deteriorate.

Oxidative deterioration is the main cause!

If the wine comes into contact with iron, the shelf life and taste will change, and it is certain that it will deteriorate. But if you drink it quickly and drink it before it spoils, you can use iron and aluminum.

For long-term storage, it is better not to use that kind of container. This is also for personal safety.

Only contact with inert containers or oak barrels.
