What to do if the mirror mercury is damp and has dark spots

1. Do not touch the mirror with wet hands, and do not wipe the mirror with a damp cloth to avoid increasing moisture pouring;

2. The mirror should not come into contact with salt, grease and acidic substances, which are easy to corrode the mirror;

3. The mirror surface should be rubbed with a soft dry cloth or cotton to prevent the mirror from being rubbed;

4. You can use a soft cloth or an abrasive cloth and dip it in some kerosene.

or wax wipe; 5. Wipe the mirror and frame with a rag dipped in milk to make it clear and bright;

6. Before bathing, the soap can be smeared on the mirror, and then wiped with a dry cloth, and a layer of soap film will be formed on the mirror, which can prevent the mirror from blurring;

7. Use a dry rag dipped in an appropriate amount of washing spirit.

Apply to mirror surface and spread evenly. The active ingredient contained in Detergent can effectively prevent water vapor from condensing on the mirror surface, and can play a good role in anti-fogging;

8. Astringent lotion can also be used.

or dish soap; 9. Wipe it with oil-absorbing paper, the effect is good.

At present, there are anti-fog mirrors on the market**, mainly coated anti-fog mirrors and electric heating anti-fog mirrors. The former blocks the fog layer through the micropores of the coating; The latter increases the humidity of the mirror through electric heating, and the fog evaporates quickly, so that the fog layer cannot be formed, and the value of this mirror is very high.

In terms of material, mirrors are divided into two categories: aluminum mirrors and silver mirrors. When we choose mirrors, try to choose silver mirrors, mercury.

High density, easy to fit closely with glass, not easy to get damp, can be used for a long time, the most advanced waterproof mirror on the market is mostly silver mirror.

1. Do not wipe the surface of the mirror directly with a damp rag, as this may cause moisture to enter the mirror surface and affect the effect and life of the mirror;

2. Apply soap to the surface of the mirror, wipe it with a soft cloth, and the water vapor will not adhere to the surface of the mirror;

3. Do not use corrosive detergents such as strong acids and alkalis to clean the mirror, which can easily cause corrosion to the mirror;

4. The mirror surface should be rubbed with a soft dry cloth or cotton to prevent the mirror from being rubbed.

5. Wash it with vinegar on the cloth.

Manufacturing Method: There are two methods of surface processing for glass to form a reflective imaging surface: electroless silver plating and vacuum evaporation, and the most commonly used is electroless silver plating. This method is to dissolve silver nitrate in water, add ammonia and sodium hydroxide solution and dilute it into silver hydroxide ammonia double salt to make silver plating solution.

Invert sugar or formaldehyde, potassium sodium tartrate solution as the reducing solution. After the glass is cut, edging (grinding and polishing if necessary), and the surface is washed, it is sensitized with a dilute solution of stannous chloride, then washed, and then mixed with silver plating solution and reducing solution to immediately immerse the surface, and the mirror surface is washed after it is formed, and then it can be plated with copper and coated with protective paint.

The vacuum evaporation method is to wash the glass, put it in a vacuum evaporation device, and electrify the spiral tungsten wire, and the high temperature generated evaporates the aluminum alloy in the spiral into a gaseous state and deposits it on the surface of the glass to form a mirror. An electron gun can also be used instead of tungsten wire for heating. Vacuum evaporation also allows smooth metal surfaces to be processed into mirror surfaces.

Mirrors are simply made at home.

Plating o 5 square meters of mirrors, 5 grams of silver nitrate are required

Ammonia (25%) 10 1 5 ml, sodium hydroxide 2 g, glucose 1 3 g, alcohol 25 ml, a little stannous chloride. First prepare a solution, take silver nitrate and put it in a clean and oil-free 500ml glass, add 100ml of distilled water to dissolve, add ammonia dropwise, and mix while adding. Initially there is a gray precipitate; Continue to add ammonia until the precipitate is completely dissolved.

After the solution is clear, add 2 grams of sodium hydroxide to 50 ml of water-soluble angle and pour it in, and cool it.

With a glass cleaner, spray some, use waste newspaper or an old cloth, and wipe it briefly.

Just scrub it with dish soap and you're good to go. The mirror surface should be rubbed with a soft dry cloth or cotton to prevent the mirror from being rubbed.

Apply soap to the surface of the mirror and wipe it clean with a soft cloth.

You can use a soft cloth (or abrasive cloth) dipped in kerosene or wax to wipe it off.

Wipe with astringent lotion or dish soap.

It should be a mold spot and cannot be treated, because it is within the surface of the mirror, and it can only be controlled and prevented.

Because the mirror is very afraid of moisture, try to place it in a dry place. However, the bathroom mirror filled with moisture will inevitably be contaminated with moisture, and black spots will deteriorate after a long time. When it comes to maintaining your bathtub and basin, don't forget to take care of your mirror.

Why are mirrors afraid of moisture? Mirror glass is generally cut before use. Water vapor can easily enter the mirror surface from the side cut by the glass knife, corroding the mirror surface, resulting in mildew and rust spots.

So, after you buy the mirror, you should apply a coat of paint to the side of the mirror and a coat to the back as well.

Mirror Wipe Method:

1. Do not touch the mirror with wet hands, and do not wipe the mirror with a damp cloth to avoid increasing moisture pouring;

2. The mirror should not come into contact with salt, grease and acidic substances, which are easy to corrode the mirror;

3. The mirror surface should be rubbed with a soft dry cloth or cotton to prevent the mirror from being rubbed;

4. You can use a soft cloth or abrasive cloth, dipped in some kerosene or wax to wipe;

5. Wipe the mirror and frame with a rag dipped in milk to make it clear and bright;

6. Before bathing, the soap can be smeared on the mirror, and then wiped with a dry cloth, and a layer of soap film will be formed on the mirror, which can prevent the mirror from blurring;

7. Use a dry rag dipped in an appropriate amount of detergent to apply to the mirror surface, and spread evenly. The active ingredient contained in Detergent can effectively prevent water vapor from condensing on the mirror surface, and can play a good role in anti-fogging;

8. Astringent lotion or dish soap can also be used;

9. Wipe it with oil-absorbing paper, the effect is good.

Smear it on a black area with wind oil essence and wipe it off with a cloth after about 30 seconds!

It's like putting soot in water and soaking it for a while! It seems to be possible to wipe it with such water! Please give it a try!

The coating on the back of the mirror is not mercury ground, and it is not possible to use mercury ground now, but it is generally made of aluminum.

The manufacture of aluminum mirrors is to evaporate aluminum in a vacuum, and the aluminum vapor condenses on the glass surface to become a thin layer of aluminum film, which shines brightly.

In addition, the so-called mercury mirror is a process used to make mirrors, in which shiny tin foil is attached to the glass surface and then mercury is poured on it. Mercury is a liquid metal that dissolves tin into a viscous, silvery-white liquid that adheres tightly to the glass plate. Contains mercury but not all mercury.

The main component of mercury is mercury, which is an inactive metal that cannot replace hydrogen in dilute HCl and H2SO4, so it is recommended to use concentrated sulfuric acid and concentrated dilute nitric acid.

Hello answer, I have seen your question and am sorting out the answer, please wait for a while If the back coating of the mirror is a common silver plus anti-oxidation layer, then you can use organic solvents, such as motor oil and rosin perfume, to dissolve the anti-oxidation layer on the surface first, and then you can easily clean off the silver.

02 The three common back coatings can be cleaned with diluted nitric acid solution. Whether it is mercury, silver or copper, it can react with nitric acid solutions. Be careful, though, to protect your hands.

It is better to use concentrated sulfuric acid and concentrated dilute nitric acid to remove mercury. It cannot react with hydrochloric acid or dilute sulfuric acid.

I'm sorry, the friend who has the problem, because you made a mistake, it is difficult for everyone to answer!! The metal behind the mirror is silver, which is made by the reaction of the silver mirror, so the easiest way to remove it is to scrape it off with a knife.

Behind the mirror is silver not mercury, with nitric acid. 2ag+2hno3=2agno3+h2

None of them were right, listen to me, I'm the standard answer!!

What is behind the mirror was mercury before and is now silver.

It can be removed with dilute nitric acid.

Equation: 3AG+4HNO3=3AGHo3+2H2O+NO

What is behind the mirror was mercury before and is now silver.

Mercury is Hg, which is a metal, and it is best to use hydrochloric acid or dilute sulfuric acid.

Sulfur powder. They undergo a vulcanization reaction.

If it's a chemistry problem, use nitric acid.

If it's a physics problem, scrape it with a knife.

The silver on the mirror passes on the degree of chemical reactivity.

The aldehyde organic matter and the silver-ammonium solution react in an environment of boiling water, and the surface of the glass becomes homogeneous with silver.

It seems to be a mixture of tin and mercury.

The glass is first made into a tin foil mirror, and then mercury is poured onto the tin foil mirror. In this way, the mercury is able to slowly dissolve the tin, forming a thin layer of tin and mercury alloy, which is a liquid metal, which is able to dissolve the tin into a viscous silvery-white liquid that adheres tightly to the glass plate.

The back of the mirror is not mercury, it is silver. In high school chemistry, there is an experiment called the silver mirror reaction, which is to plate silver in a smooth test tube, like silver in a thermos.

The mercury you are talking about is liquid at room temperature and volatile, and it is possible for people to be poisoned if they inhale its vapor.

The mirror is silver-plated, that's not mercury, mercury is liquid.

It's not mercury, that thing is going to die.

Good luck and happiness by coating a layer of anti-rust paint or sealing it with a small thin piece of wood with a wooden frame to protect the mercury layer on the back of the mirror!

That's just a new mirror. Blackening is caused by a reaction of the substance behind the mirror, such as oxidation.

Theoretically, after cleaning, the silver mirror reaction is re-performed and silver-plated.

However, it is not necessary and cannot be done, because when cleaning, the glass may be scratched, and there will be scratches when it comes out again.

If it's scratched, it's only brushing.

The mirror is sprayed with a layer of mercury on top of the glass, followed by a coat of paint. Removing the mercury is a piece of glass! Why should you cover the back with a layer of paint, because mercury is harmful.

To remove mirror mercury, use "silver washing water", which is also a harmful chemical. 35 percent hydrofuser acid can also be removed, which is like sulfuric acid....

1. There is basically no remedy for the metal behind the mirror, find a craftsman to plating a layer on it, or buy a new one.

2. You can also try to use highly reflective materials such as tin foil to stick on the back as a substitute for mercury coating;

3. Focus on prevention, you can paint the back of the mirror to protect the others.

It is silver or aluminum, which can be re-chemically plated if necessary.

To see if there is any replenishment of mercury, take it to the mirror factory to see.
