Why does the smell always appear in the car after driving for a long time?

After driving for a long time, there is always a strange smell. In fact, these smells are caused by the unclean air conditioning system or our habit of eating and smoking in the car. How to fix it? Share a few solutions with you. There are three common methods to remove odor.

1 type, physical adsorption deodorization.

In fact, bamboo charcoal package, activated carbon and other things that can absorb the surrounding odor are put in the car, and the odor is absorbed by adsorption, neutralization reaction and oxidation reaction as the main mechanisms. This method has a certain effect, but it takes a long time to be effective.

Second, cover up the smell with perfume, that is to say, spray perfume in the car, or put a bottle there directly.

It is not safe to put things on the center console, but this method itself does not have much effect and does not completely solve the source of odor. A variety of smells are mixed together, and maybe the smell inside the car is even worse and weirder.

The third type, chemical decomposition and deodorization, is the principle of using chemical molecules to absorb odor sources and then decompose them.

Xin of Hebei Agricultural University has a master's thesis "Study on Extraction and Deodorization Activity of Persimmon Tannin", which explains the common odor in life.

Such as sweat, foot odor, tobacco smell, garbage smell and so on. In fact, it is a mixture of volatile low molecular compounds.

Technically, there is a scientific name: ammonia, acetaldehyde, acetic acid, isovaleric acid and so on. Most of these compounds belong to hydrophilic compounds, and chemical molecules in plant extracts can react with these compounds in acid-base reaction, catalytic oxidation reaction, redox reaction and so on.

The reaction product has no odor or little odor, thus achieving the deodorization effect. This method of decomposition and deodorization is faster, shorter and safer than the two mentioned above.
