Books will slowly turn yellow and get old if they are kept for a long time. At this time, bugs will come to visit. Bian Xiao's grandfather used to be a teacher. He was very careful about books. Grandpa has a bookshelf at home. For books that are not commonly used, he will wrap mothballs on them. The strong smell of moth balls can drive away pests and diseases, and can effectively avoid insect eating.
2. Nitrogen water can erase the mildew spots on books.
The paper in this book is fragile and needs maintenance. Once it comes into contact with steam, the paper will grow mildew and smell bad. You can wipe off the mildew spots on the book with nitrogen water, just dip a cotton swab in nitrogen water and wipe it gently.
Bread pulp can absorb the dust on books.
The dust removal effect of bread pulp is obvious. First, blow away the dust on the book. If it doesn't blow, you can wipe some water with bread pulp. After use, the book can turn white again.
The tobacco leaves sandwiched in the pages can prevent insects.
There are many mosquitoes in summer. At this time, cut tobacco or tobacco leaves can be put in the pages, which can effectively play the role of insect repellent, thus strengthening the protection of books and also playing an obvious role in preventing mosquito bites at home.

Book preservation method:
1, temperature and humidity control
Environmental protection requirements for paper cultural relics: According to relevant research results, the optimum indoor temperature is 15℃ in winter and 25℃ in summer, and the relative humidity should be kept between 50% and 65% all the year round. In addition, the indoor temperature change shall not exceed 5℃ and the humidity change shall not exceed 5% within 24 hours.
Otherwise, the tensile strength of paper fiber will be greatly affected, and a large number of bacteria and microorganisms may breed. According to this requirement, what the family can do is to buy an instrument to measure the temperature and humidity of the storage place and judge whether the environment is suitable according to the readings of the instrument. If it is not suitable, it is necessary to use equipment, such as air conditioning with temperature control and humidity reduction, and humidified air humidifier.
2, mildew prevention
The two most terrible diseases of books are mildew and moth-eaten. In addition to temperature and humidity control, mildew prevention should also be ventilated in time to make it difficult for mold to breed. However, due to the air quality problems in China, it is necessary to install air purification devices to reduce dust and ventilation time during the period of serious pollution.
Step 3 control lighting
Strong light and ultraviolet rays will lead to brittle cracking and yellowing of paper cultural relics, so it is best to replace the glass in the preservation place with dark glass and the light bulb with low wattage and low ultraviolet light source to minimize the illumination time. Try to put ancient books in boxes or shelves that are not exposed to direct sunlight.
4. Insect prevention
The most effective way is to create a low-oxygen environment, use a box with good air tightness and fill it with inert gas, but the cost and technical difficulty are very high. If you can't do this, you can put some insect-proof devices, such as camphor, and seal the books in plastic bags. In addition, do a good job of killing rats and cockroaches.
5. Correct access methods
After entering the storage space, people put on masks and gloves to take and put books; Books should not be placed for a long time, and thread-bound books should be placed flat; The cabinet should be at least 25mm away from the ground, and avoid being placed against the wall; There is no open flame. If there is heating, it must be maintained. Don't let it run out of water.
