Definition and application principle of anionic powder coating

In general, adding a certain amount of anionic additives to the powder coating can produce the anionic powder coating We know from common sense that people usually like to travel to the park or the countryside and feel the air is fresh The important data is the concentration of negative ions Generally, when the negative ion concentration reaches 500-1000 / cm3, the air can be fresh and the human health can be maintained The mechanism of producing negative ions in the negative ion powder coating: each unit of the negative ion additive added in the powder coating has a permanent electrode When the water molecules in the air contact with it, the permanent electrode will discharge in a transient time, making the water molecules electrolyze The chemical equation is as follows: H2O = H + + OH hydrogen ion H + absorption electron: 2h + + 2E = H2 hydrogen oxygen ion oh- Reaction with water: Oh - + H2O = H3O2 - (negative ion) due to the continuous release of negative ions, in addition to achieving the effect of air freshness, it can also neutralize and coat harmful gases with positive charges such as formaldehyde and benzene and bacteria such as Staphylococcus aureus, which plays a role in air purification Anionic powder coating is generally used in office furniture, hospitals, public places, etc.
