Chemical deodorization
Chemical deodorization is the process of converting odorous components into odorless ones through chemical reactions. For example, both the antibacterial and deodorizing stick of Ke Ningling refrigerator and the deodorizing stick of Pablo refrigerator utilize the principle of chemical deodorization. These deodorizing sticks release chlorine dioxide gas, which has strong oxidizing properties and can undergo oxidation reactions with odorous sulfur-containing pollutants, converting them into other odorless substances and achieving deodorizing effects.
Physical deodorization
Physical deodorization is achieved by adsorbing or decomposing odor components. For example, activated carbon has a porous structure that can adsorb odor components and reduce emitted odors. In addition, some deodorizing sticks may also incorporate negative ion technology to purify the air and increase its freshness by releasing negative ions
