The negative ion in the bus air purifier is a kind of purification technology2021-07-15
If you have studied high school chemistry, you will know that atoms are composed of positive ions and negative ions. In an air purifier, atoms will be decomposed into positive ions and negative ions by the electric current inside.
Negative ions are unstable and cannot exist alone. There are various positive ions or macromolecules in the air, including pollutants, and then the negative ions will combine with the pollutants and eventually become a cluster of precipitates. Floating in various places in the bus, it finally achieves the role of air purification.
Because these pollutants will fall in various places, it will be difficult to clean and the treatment is not clean. Nowadays, many high and new technologies have emerged to solve these problems and achieve the effect of purification.
