Question 2: There are several forms of book mildew, how to deal with it? The reason why the book is moldy is humidity. Don't dry it quickly, it will wrinkle.
The simplest and most commonly used method is:
1. Completely soak in alcohol (this is necessary to restore dryness and smell).
2. Press it firmly with gypsum board or porcelain.
3. It will dry quickly (alcohol evaporation will not leave moisture) and be as flat as new, without moth and mildew.
The best way to prevent it from getting moldy again is not to put it in a place that is easy to get wet. This is the basic common sense of keeping books.
Question 3: Why do books get moldy after being kept for a long time? Generally speaking, paper turns yellow because of oxidation. If we can avoid oxidation as much as possible, we can also avoid yellowing of the paper. As long as you can guarantee the following three points, paper yellowing can basically be avoided. These three points are to reduce contact with air, water and sunlight. For most people, contact with air is inevitable, but contact with moisture and sunlight can be avoided as much as possible. If you don't use some books often, you can try to seal them in a plastic bag and take them out when you use them. Usually, the shelf life of paper should not exceed one year. Even if the storage conditions of paper are good, the paper will change color and deteriorate if it is stored for too long. If the paper is stored for two years, the coated paper will turn yellow and lose powder; Newsprint turns yellow and brittle; The wrapping paper is discolored and its strength is reduced; Yellow paperboard and box paperboard will go moldy and deteriorate, and so on.
Question 4: What should I do if the book is moldy? Give you the methods I often use: first, the books should be placed in a ventilated place. If it always rains and the air is humid, we should take them outside to bask in the sun and drive away the tide. Second, you can use household electric fans and hair dryers to blow hot air. Third, we should pay special attention to precious and classic books, which can be framed or sealed and taken care of with preservatives, desiccants and insect repellents. The above is my book protection method. I hope I can help you.

Question 6: What should I do if the book is moldy? How to get rid of it? 1 50 points. Wipe with strong ammonia water.
2, 84 disinfectant with water evenly coated on medical cotton, dry.
Soak it completely in alcohol (thus reducing dryness and odor), and then press it firmly with gypsum board or porcelain. This book is suitable for damp and moldy.
Question 7: The book is moldy. What should I do? This book is moldy. What should I do with it? The reason why the book is moldy is humidity. Don't dry it quickly, it will wrinkle.

3. It will dry quickly (alcohol evaporation will not leave moisture) and it will be as flat as new, and the musty smell will disappear.
The best way to prevent it from getting moldy again is not to put it in a place that is easy to get wet. This is the basic common sense of keeping books. Books should also be maintained frequently, or they will get moldy. You can take them to a sunny place to cool down, but exposure is not recommended!

Insects can use this method: old books are easily damaged by insects if they are not well protected. If books are infected with insects, wrap them in plastic bags and put them in the refrigerator 12 hours or so, moths will freeze to death. If you soak a book in water, whether it is dried in the shade or in the sun, the paper will wrinkle and yellow easily. At this time, if the soaked handwriting is erased and put in the refrigerator for two days, the book will return to its original state. In addition, first clean the old books with alcohol balls, then put them in plastic bags and freeze them in the refrigerator for two days, which can not only sterilize, but also wipe off dirt and smooth the old books as new. Wine is the fragrance of old age, so is a good book. An enduring masterpiece is like a good wine for many years. If you want to savor the taste, it will be memorable.
This is the method to teach you how to prevent insects and some protection books: 1. Stereoscopic microscope detection.
By examining the fragments with a stereo microscope, you can know whether there are insects. Once the egg was found to be stuck, the repairman took immediate action to save the country.
In this way, Mr. Zhong, deputy director of the Hong Kong Central Library, has repeatedly restored the pocket edition of ancient books. Through the microscope, we can clearly see the part that needs to be repaired and the joint position between the page and the prosthesis, so as to accurately repair the anastomosis.
Second, quick freezing and cold storage insect prevention methods
Put the book into a plastic bag, pump out most of the air, seal it, put it in the freezer, adjust it to -30℃ for quick freezing, and kill the bookworm at low temperature after cold storage 10. If you want to deal with a large number of books, you can send them to museums and other units for processing. There is a nitrogen killing room. Put the books with insects in a sealed iron cabinet, so that the oxygen content in the cabinet can be kept below 0.3%, and pests and eggs can be completely killed.
Why not use more direct chemical pesticides? Mr. Zhong said that under normal circumstances, we do not encourage the use of chemical reagents, because it will pollute the environment and cause safety problems to users. In addition, many chemicals will remain in the literature, which will have a negative impact on the literature. In the future, when readers or researchers browse, they may also bring harm to themselves, so this practice is dispensable.
Three, foreign body removal method
In addition to pest control, there are many problems that the restorers of historic sites must deal with. For example, all the recycled books have been used, and some inappropriate repair materials, such as labels and scotch tape, will leave residual stains over time, making the pages yellow. There are also some nail books, which have been oxidized for a long time. When iron is oxidized, it will become larger and even tear the stapled pages.
