1.Core mechanism:powerful oxidative disinfection principle

　　To understand the wide range of uses of cheap calcium hypochlorite disinfectant tablets,it is first necessary to understand their mechanism of action.Calcium hypochlorite(Ca(ClO)₂)belongs to chlorine containing disinfectants,and its core disinfectant component is hypochlorous acid(HClO).When disinfectant tablets are put into water,a hydrolysis reaction occurs,generating hypochlorous acid and hypochlorite ions.
　　Hypochlorous acid(HClO)is a small,electrically neutral molecule with extremely strong oxidizing properties.It can easily penetrate the cell walls or viral capsids of microorganisms such as bacteria and viruses,and destroy them through various pathways:
　　-Oxidized protein:destroys its structure and inactivates enzymes that maintain life activities.
　　-Destruction of nucleic acid:Oxidative decomposition of DNA or RNA,causing it to lose its genetic replication ability.
　　-Damaging the cell membrane:disrupting its permeability,causing leakage of cellular contents,and leading to microbial death.

　　It is precisely this indiscriminate and potent oxidative attack that makes cheap calcium hypochlorite disinfectant tablets have a broad-spectrum and efficient killing effect on the vast majority of pathogenic microorganisms,including bacterial reproductive bodies,viruses,fungi,and bacterial spores.
