1, anti-aging, books become brittle with aging.
The plant fiber in paper loses its strength and adhesion after being hydrolyzed by acid, and the acid in paper mainly comes from aluminum sulfate in pulp. When the paper begins to get wet, aluminum sulfate begins to produce sulfate and hydronium ions, and finally forms acidic substances, which corrode the paper. Sulfur oxide and cyanogen oxide in polluted air can also react with water or plant fiber itself to produce acid.
In order to prevent books from aging and embrittlement, the most important thing is to remove the acid from the paper. Now the most commonly used method is to soak books in magnesium bicarbonate or calcium bicarbonate solution and then dry them. This can remove the acid from the paper and prevent the acid reaction from happening again in the future.
2. Pest control.
1), the items in the warehouse should be clean, dry and well ventilated; There should be no cracks on bookshelves, walls or floors;
2) The temperature of books and articles should always be kept at 6-20 degrees and the humidity should always be kept at 50%-60%;
3), books should be moved frequently, even books that are not commonly used should be turned over regularly;
4) On the bookshelf or bookcase, you can put some wrapped sanitary balls.
3. decontamination.
1), except oil. Put a piece of absorbent paper on the oil stain and iron it gently for a few times to absorb all the oil.
2), in addition to ink marks. If there are brown spots, oxalic acid or citric acid solution can be used to remove them.
3), in addition to mildew spots. Soak the cotton in ammonia water and gently wipe the mildew spots until it is clean.
4), in addition to fingerprints. Wipe off fingerprints with soap first, then wipe off soap traces with a wet cloth, and finally draw lines on the pages with absorbent paper to absorb water.
5), except flies. Dip cotton in vinegar or alcohol and gently rub it on the fly's excrement until the stain is removed.
Extended data:
Put the book at home, need to pay attention to a few questions:
1, the room should be cleaned frequently, and there should not be too many sundries. Otherwise, cockroaches will breed and stain books, which is very annoying.
I am used to using bookshelves, so it is convenient to take books. If you like neatness, use bookcases, which can greatly reduce the dust on books.
If all these things are done, and you live in a building and can keep the books dry, you don't have to dry them.
4. The wardrobe also needs to be protected from insects and moisture, as above.
5. Appropriate use of mothballs and other pest control methods.
