The circulation of books in modern society is great, it is obviously impossible to use cotton and linen paper, so most of them are wood as raw materials.
The plant fiber in paper is acid hydrolyzed to lose strength and adhesion, and the acid in paper is mainly from the aluminum sulfate to paper pulp.
When the paper began to damp, aluminum sulfate began to produce sulfate and hydrated hydrogen ions, and finally formed acid substances, paper erosion.
The oxidation of sulfur and cyanogen in polluted air also reacts with water or plant fiber itself to produce acid.
Therefore, prevent book aging become brittle, mainly to remove the acid in the paper.
The most commonly used method is to place the book in magnesium bicarbonate or calcium bicarbonate solution and then dry it. In this way, you can get the acid in the paper and prevent the acid reaction from occurring later.
Ii. pest control. Books sometimes grow bugs, which seriously endanger the life of the book.
The method of preventing worms is:

Place a water absorbent paper on the bottom of the page with traces of ink, then immerse the stain with 20 % hydrogen peroxide solution or potassium permanganate solution, then place a water absorbent paper on the top of the page and press heavy objects, and the ink will disappear after dry. If there are brown spots with potassium permanganate solution, you can remove it with oxalic acid or citric acid solution.
3 、 chumei spot. Dip the ammonia water with cotton, gently wipe on the mildew stain until clean.
4, except for finger printing. Wipe the finger print with soap, wipe the soapy traces with a damp cloth, and finally put water on the pages of the pages to dry up the water.
5, except the fly. Dip the cotton in the vinegar or alcohol, rub it lightly on the fly, and wipe it off.
For other general stains, as long as the use of soap carefully wipe, then use a wet cloth to wipe the soap, and then on the book ink suction paper suction dry water, you can receive a more satisfactory effect.
