What is the composition of the smell of books? Is it harmful to the human body?

The odor in the book is caused by the reaction and decomposition of various compounds used in the manufacture of paper, and the specific composition is not clearly reported for the time being, but it can be known that there is not much harm to the human body.

Most of the paper is made from wood pulp, but some are also made from cotton and fabric. Paper requires a lot of chemicals, such as sodium hydroxide, in the manufacturing process.

In the manufacturing industry, it is often referred to as "caustic soda." , which is used to raise the pH level.

and swelling the fibers of wood pulp; Hydrogen peroxide.

It is used to drift fibers; It is then also mixed with a large amount of water. And there will be additives in these waters, mainly to adjust the properties of the paper, such as alkyl enone dimers, which are used to improve the water resistance of the paper. So these chemicals release and volatilize organic compounds through reactions or other processes, so that we can smell books.

The same is true for chemicals in inks and binding adhesives. There are many different adhesives used in book binding, many of which are based on organic "copolymers" – large aggregates of small molecular chemical chains. Different paper, adhesive and ink use can affect the "new book smell", so not all new books smell the same.

There are a number of compounds whose role is well understood: benzaldehyde gives almond flavor, vanillin.

Vanilla scent, ethylbenzene added.

and toluene add a sweet smell, and 2-ethylhexanol has a slight floral odor. The low olfactory threshold of other aldehydes and alcohols produced in these reactions also contributes to the production of bookish aromas.

In general, as with many odors, we can't just refer to a particular compound or a group of compounds and assume that that is the cause of the smell, but we can identify potential contributors, especially in the study of odours in old books, where a range of compounds have been proposed.

Generally speaking, the ink smell of books printed with regular ink will slowly disappear after a period of time. There is little impact on human health. At present, some provinces and municipalities in China that have the conditions have begun to require that the textbooks and textbooks of primary and secondary school students must be printed with completely harmless ink.

The smell of books is the smell of ink and formaldehyde. The formaldehyde content is not so high, so it will not cause any damage to your body, so it is completely irrelevant, and you can use it with confidence.

The smell in books is not harmful to the human body, and the smell in books is actually the smell of trees being made into pulp, and then made into paper, and bound into books.

These odors are produced by the paint used in the printing of books, and this odor is harmful to the human body if inhaled for a long time.

The smell of books is poisonous.

Used books: Foreign scientists sampled the air emitted by old books and found that there are many aromatic compounds such as benzaldehyde (almond flavor), vanillin (vanilla flavor), toluene, ethylbenzene (sweet flavor) and 2-ethylhexanol (floral flavor), which is why many people are obsessed with old books.

It's not just one flavor, it's many. These components are actually very low, but they are volatile, and our sense of smell can detect them at very low concentrations.

New book: Containing formaldehyde and benzene is not only harmful to the respiratory tract, but also carcinogenic in serious cases.

The ink of color printing is generally dissolved with a solvent such as benzene, and after printing, when the magazine is not opened, the solvent such as benzene is not completely volatilized, and after opening the book, this solvent will continue to volatilize and produce an unpleasant odor.

Benzene and toluene are colorless, strong odor liquids, with strong toxicity, can cause acute poisoning, paralysis of the central nervous system and other hazards.

Ways to get rid of odors from books:

1. It is best to put those poor green teas, or lime and bread, and put them and books in a closed box, and let them be left for a few days to remove moisture, and there is a clear fragrance of tea.

2. Draw out each compartment in the bookcase.

Three or four books, with a few pages of paper towels in them, can be easily removed after putting them back in their place.

3. Put a certain number of children's mothballs in the bookcase.

Put 1 2 pieces on each layer to prevent the books from being insected.

4. Books should not be damp, and books should not be placed too low or close to the ground, nor near the stove or a place where the sun is often exposed.

Go buy a sealed bag, (there are supermarkets, or stores that sell plastic bags in the market, 2 cents 1) put the book in a sealed bag and put it in the refrigerator freezer for a few hours, and immediately put it in the sun for two hours after taking it out, the smell will be almost gone, you can try it, because there are very favorite books that have experienced similar encounters, have experience in dealing with them, I hope it will be useful to you.

The vinegar removes the fishy smell, but it is not a bubble, and by the heating method, the vinegar is evaporated, and the book is placed on top of the steam. Then expose to the hot sun.

It is recommended that you clean the book with a special detergent first, and add scented petals and leaves to the book where appropriate!

You can try it!

Use activated charcoal to make a powder and put it in a book, and then use air freshener a few days later.

Put it in the sun and spray it with some toilet water or something. Vinegar is also good.

It can be taken out for a period of time to dry.

The smell of books is not harmful to people. The smell of books is the smell of ink.

Ink: It is an important material used for the printing of packaging materials, which expresses the pattern and text on the substrate through printing, and the ink includes the main components and auxiliary components of the bending, which are evenly mixed and separated by repeated rolling into a viscous colloidal fluid.

Problem description: I have a book that accidentally came into contact with moldy eggs, and now the book smells of rotten eggs, how can I get rid of the smell of rotten eggs?

Analysis: 1When the book is stained with oil, put 1 piece of absorbent paper on the high trace of the oil bush, and gently iron it several times with an iron, and the grease can be sucked into the paper to make the pages smooth and clean.

2.If the book is polluted by ink, you can put 1 sheet of absorbent paper under the page of the dyed ink, soak the stain with 20% hydrogen peroxide solution, and then put 1 sheet of absorbent paper on the page, and press a chunqing weight on the top, so that the ink is dissolved and absorbed by hydrogen peroxide, and the ink stains will disappear naturally after drying.

3.If there are damp marks on the book, it can be washed with an alum solution. If it is rust stains, you can wipe it off with oxalic acid or citric acid solution, then wash the pages with clean water, press the pages with blotting paper, and dry them.
