How to deal with yellowing of the pages

There is no way to deal with yellowed pages.

Generally, the yellowing of book paper is due to oxidation. If you can avoid oxidation as much as possible, you can also avoid the yellowing of the paper.

As long as you can ensure the following three points, the yellowing of the paper can basically be avoided.

These three points are to reduce contact with air, reduce contact with moisture, and reduce contact with sunlight.

Generally, the storage period of paper should not exceed one year, even if the condition of storing the paper is good, the paper will be discolored and deteriorated if it is stored for too long. If the paper is stored for two years later, coated paper.

It will turn yellow and depowder; newsprint turns yellow and brittle; Discoloration and reduced strength of the wrapping paper; Yellow cardboard and containerboard can become moldy and deteriorate, and so on.

In addition to the aging of the paper itself and the destruction of paper fibers caused by oxidation, the addition of chemicals to modern machines makes a large number of paper is also easy to make the paper acidic, and the adverse environment (such as air pollution, ultraviolet rays.

Factors such as temperature, humidity, etc.) and man-made damage will be the factors that cause the deterioration of paper.

As far as I know, the printed paper is bleached, and over the years, the effect of bleaching naturally weakens, and the paper gradually turns yellow. Do you have a collection of antiquities? Isn't the yellow page more reminiscent of the vicissitudes of history?

Think about it, in the long winter night, what a good artistic conception is the yellow roll and green light?

But I think I can use a sprayer to fill a solution with bleach and spray it evenly on the book paper to see if it works.

1. Removal of dye stains.

If the dye gets on the clothing, you can wipe it with dilute acetic acid and then rinse it with hydrogen peroxide. It can also be brushed with turpentine and then wiped with gasoline. Finally, rinse with clean water.

2. Removal of red ink stains.

Freshly dyed red ink stains can be washed with water, then soaked in warm soap, and then washed off with clean water after the stains are removed. Red ink stains that have been polluted for a long time should be washed with water first, and then wiped with 10% alcohol aqueous solution to remove them.

3. Removal of blue ink stains.

Newly stained blue ink stains can be removed with soap, laundry detergent and other detergents. Blue ink stains that have been contaminated for a long time can be soaked in oxalic acid solution and then scrubbed, and then cleaned with detergent to remove.

4. Removal of red potion stains.

The clothes are dyed with red potion, first washed with warm detergent solution, then soaked and scrubbed with oxalic acid and potassium permanganate solution respectively, and finally decolorized with oxalic acid solution, and then washed with water, and the red potional stain is removed.

5. Removal of purple potion stains.

The main ingredient in the purple potion is extracted from gentian grass, so the purple potion, also known as gentian purple, is a commonly used topical agent, stained on clothing, blue and purple color, very conspicuous.

The removal method is to soak the clothes in water, wring them out slightly, and use a cotton swab dipped in 20% oxalic acid aqueous solution to apply the stain from the inside out. After a short period of rest, you can rinse and rub repeatedly with water to remove the stain.

In addition, for some white fabrics stained with purple potion, you can also use solvent alcohol to remove the floating color, and then use the oxidant sodium or hydrogen peroxide solution for bleaching, and the expected effect can be achieved after washing.

6. Removal of yellow syrup stains.

Light-colored, especially white clothes, sprinkled with yellow syrup, to remove yellow syrup stains is more troublesome, first use acetic acid drops on the polluted place, if the effect is not great, you can put it in alcohol to wash.

If the book is yellowed, we need to remove the marks and make the book cleaner, we can use some chemical methods or apply some whitening agents.

Books are yellowed because they are oxidized, and if you want them to be clean, you need to reduce contact with air, moisture, and sunlight.

After the book is yellowed, you can use some dish soap to beat the yellow to go down, and then use a hair dryer to dry it. This will also bring back the original color to the book.

The yellowing of the book is caused by the fact that the book has been exposed to the sun outside, or the wind and rain, so the result is that you can paint it with an eraser, which will be much better.

You can use cotton soaked in soapy water to scrub once or twice, and then use absorbent paper to blot the moisture dry. If there is ink stains, you can use absorbent paper to pad under the pages of the ink, gently scrub them with a cotton ball soaked in hydrogen peroxide, and then cover it with a piece of absorbent paper, press a few thicker books on the paper, and when the pages are dry, the ink will disappear. Books and periodicals can be scrubbed with a cotton ball soaked in alum water, and then the water can be blotted dry with absorbent paper.

The book is yellowed, remove the yellow marks to make the book clean, I think this yellowed book is difficult to clean, you can put it in a dry place to avoid it yellowing.

The yellowing of the book I think can be gently erased with time and then dried with a hair dryer, I think this will make the book clean.

Personally, I think that the phoenix of books is, you can use an eraser to erase, wipe the marks on the book, or you can use tape to stick it.

If the book is yellowed, you can use an eraser to remove the yellow marks of the book, which is very effective, and you can also put it in some special places.

My personal experience is that it works well to buy an eraser to wipe the yellowed area.

Gently rub the macula with a clean cotton dampened in alcohol.

1. Anti-aging. The aging and brittleness of books does not depend on the length of time, but on how to deal with the acidic substances contained in the pages. It has been found that some of the books published in Europe in the 15th century have survived to this day because the paper was made of cotton and linen heads, had a neutral pH, and contained calcium carbonate, which prevents acid formation.

In modern society, the circulation of books is very large, and it is obviously impossible to make paper from cotton and linen, so most of them use wood as raw material. The plant fibers in the paper lose their strength and adhesion when hydrolyzed by acid, and the acid in the paper mainly comes from the aluminum sulfate that sizes the paper. When the paper starts to get wet, the aluminium sulphate begins to produce sulphate and hydronium ions, and finally forms an acidic substance that erodes the paper.

Sulphur oxide and cyanide oxide in polluted air can also react with water or plant fibers to produce acids. Therefore, to prevent books from aging and becoming brittle, the main thing is to remove the acid in the paper. The most common method now is to soak the book in a solution of magnesium bicarbonate or calcium bicarbonate and then dry it.

By doing so, you can get the acid in the paper and prevent the acid reaction from happening later.

2. Insect control. Sometimes small insects grow on books, which seriously jeopardizes the lifespan of books. The way to prevent insects is:

1. The articles in the collection should be clean and dry, and well ventilated; There should be no cracks in the bookshelves, walls, or floors; 2. The temperature of the collection of books and articles should always be kept at 6-20 degrees, and the humidity should be kept between 50% and 60%; 3. The collected books should be moved frequently, even if they are not commonly used, they should be turned regularly; 4. On the bookshelf or in the bookcase, you can put some wrapped sanitary balls.

3. Decontamination. Stained books will not only shorten the life of the book, but also affect the effect of reading. The method of decontamination is:

1. Degreasing. Put a piece of absorbent paper on the oil stain and gently iron it several times with an iron to absorb the oil. It can also be erased with a few drops of a mixture of gasoline and magnesium oxide.

2. Ink removal. At the bottom of the page stained with ink, first pad a sheet of absorbent paper, then soak the stain with 20% hydrogen peroxide solution or potassium permanganate solution, then put a piece of absorbent paper on the top of the page, and press a heavy object, and the ink will disappear after drying. If brown spots occur with a potassium permanganese solution, they can be removed with oxalic acid or citric acid solution.

3. Remove mildew. Dip cotton in ammonia and gently rub the mold until it is removed. 4. Remove finger prints.

Rub your fingerprints with soap, then wipe off the soap with a damp cloth, and finally line the pages with absorbent paper to blot the water. 5. Remove fly feces. Dip cotton in vinegar or alcohol and gently rub fly stool until the stain is removed.

For other general stains, as long as you carefully wipe it with soap, then wipe off the soap with a damp cloth, and then line the book with absorbent paper to absorb the water, you can get a more satisfactory effect.

Let it go out and soak up the sun! Summer is coming! It's not practical to completely change it back, because paper is fragile and easy to break.

The paper of a book will oxidize and turn yellow when exposed to air for a long time.

This problem can be solved by sealing it up, for example in a sealed bag.

Some precious books, it is better to read less, if possible, you can put them in a well-sealed box and put desiccant.

By injecting high-purity nitrogen into the box to prevent oxidation, the paper will be exposed to oxygen and harmful gases in the air under natural environmental conditions, and oxidation and acidification hydrolysis reactions will occur.

Yellowing and brittleness of the paper, protected with nitrogen, prevents these reactions on the book paper.
