What types of activated carbon deodorant?

There are mainly the following types of deodorant: physical deodorant, chemical deodorant, microbial deodorant, plant deodorant and compound deodorant, etc.

Physical deodorant

The physical deodorant is to remove the odor by physical methods, using the physical properties of the deodorant or the odorous gas, the result of not changing the gas composition, only changing its local concentration, or the relative concentration. Common ones are adsorption deodorant, masking deodorant, etc.

Adsorbent deodorant

Absorptive deodorant is a deodorant method that uses substances with excellent adsorption capacity and uses intermolecular van der Waals force to adsorb odor molecules into porous substances. Common adsorbent deodorants include activated carbon, bamboo charcoal, and coconut carbon. The deodorant is larger than the surface and has a large empty volume, and can usually absorb and reduce the concentration of odor in the air to achieve the purpose of deodorization.

Using the latest phosphorus-free formula, after atomization, a great surface energy is formed on the surface of the tiny droplets. The surface energy can absorb odor molecules in the air, the dissolution process of odor gas, that is, the mass transfer process of the gas phase to the liquid phase, and the structure of the odor gas molecule changes and becomes unstable; at this time, the Effective molecules can provide electrons to odor gas molecules and react with odor molecules; at the same time, the odor gas molecules adsorbed on the surface of the droplet can also react with oxygen in the air. Through the action of this agent, odorless gas molecules will generate odorless and non-toxic molecules, such as nitrogen and water.

Masking deodorant

Masking deodorant is to use natural aromatic oils, spices and other substances to mask peculiar smells. Mainly for many difficult-to-remove peculiar smells or environments where deodorization is troublesome, mix several gaseous gases in proportion to reduce peculiar smell.

An odorless odor masking agent with slow release properties prepared by advanced polymer nano-encapsulation technology. The size of the microcapsules is 20-80 nanometers. It can be well dispersed in water-based liquids, and will not destroy the balance of the liquid formula after being added; at the same time, it has a natural inhibitory effect on the production of fungi and mold due to the specific properties of the product. Achieve the good effect of killing two birds with one stone.

Chemical deodorant

The chemical deodorant uses oxidation, reduction decomposition, neutralization reaction, addition reaction, condensation reaction, ion exchange reaction, etc. to change the odorless substances produced to eliminate odors.

3.2.1 Oxidation deodorant

Oxidants such as NaClO and chlorine oxidize the organic sulfur and organic amines in the peculiar smell into compounds with lighter odor or higher solubility, and then absorb and purify by acid and alkali.

3.2.2 Salt compounds

Use salt compounds as deodorants, such as ferric ions and ascorbic acid together to inhibit oxidation, and react with ammonia, mercaptans and other off-flavor substances to turn them into odor-free substances; the coordination of trivalent iron derivatives and metal complexes The position body undergoes a displacement reaction with mercaptan or sulfur to convert odorless substances into non-odorous substances.

3.2.3 Acid and alkali preparations

Use acids or alkalis as deodorants, such as the non-catalytic gas-solid two-phase reaction between zinc oxide and hydrogen sulfide, which can remove hydrogen sulfide gas in the air; flavonoids and tannic acid and other wood essential oil components through inclusion, Neutralization, addition reaction to remove odor substances.
