Good weather and books

For people who love books like life, it will be unbearable for their favorite books to be damp or moldy. Mr. Luo, a staff member of Liuzhou Library, said that the air humidity is high in March and April every year, and the southerly days last for a long time, so books are prone to mildew. Luo said that the key to moisture prevention is to open fewer windows and reduce the contact between books and humid air. If there are books in the bookcase, close the cupboard door and don't open it at will. In the closed bookcase, you can put a bag of desiccant, such as activated carbon or quicklime, to absorb the moisture in the air. If you put books on the bookshelf, you can cover the surface of the bookshelf with a layer of plastic film or cloth to reduce contact with humid air. In addition, some family bookcases are embedded in the wall, because the wall is easy to seep, so the books can be removed temporarily. When dusting a bookcase or bookshelf with a rag, dry the wet rag first and take it out when it is half dry to prevent the rag from oozing out. Pay attention to ventilation as soon as the wet weather is over. Teacher Zhang specially reminded: books have been wet, so don't expose them to the sun, so the paper will become brittle and the color will turn yellow easily.
