Calcium hypochlorite is a white granular solid (or tablets made from compressed granules) that has a chlorine odor. Toxic and irritating to skin. Not flammable, but will accelerate the burning of combustibles. Prolonged exposure to fire or heat may cause violent decomposition of the material and rupture of the container. If the diluted sample contains less than 39% available chlorine, the above reaction may occur, but will take longer to engage and the reaction will be less vigorous.

Applications

Disinfectant and fungicide

Calcium hypochlorite dissolves in water and releases HCIO hypochlorite, which acts on the protein of pathogen, denaturing the protein and causing death. At the same time, hypochlorous acid is stable, easy to decompose into atomic oxygen, atomic oxygen has strong oxidation, can oxidize pathogen proteins and kill pathogens; Hypochlorous acid can also decompose and release chlorine gas (CI), which directly acts on the protein of bacteria, denaturating the protein and killing it. In addition, the calcium chloride solution in calcium hypochlorite solution is strongly alkaline, which can dissolve the viral protein shell, which is conducive to the release of viral particles and death. Calcium hypochlorite disinfects a wide range of objects, and has a killing effect on viruses, bacteria, fungi and microparticle spores. It can also be used for disinfection of silkworm chambers, silkworm kits, silkworm bodies, silkworm seats, silkworm eggs, mulberry leaves, etc. Mainly used for drinking water, swimming pool water, Aquaculture industry, waste water, household, public sanitization in hospitals, schools disinfection and sterilization.

Bleaching agent

It is mainly used for bleaching of pulp in paper industry and bleaching of cotton, linen and silk fiber fabrics in textile industry.

Oxidizer

Used as an oxidizer, in particular for decontamination of cyanide containing sewage water in gold mining industry and off-gasses.

Deodorant

Deodorant for houseware like refrigerator or towel etc.

FAQ

Why does it need to be sealed and stored in a dark place during storage?

Because the bleaching powder essence is mainly Ca(ClO)2, CaCl2, the useful ingredient is Ca(ClO)2, and the active ingredient is HCLO If it is not sealed, Ca(ClO)2+H2O+CO2→CaCO3+2HClO 2HClO→2HCl+O2 ↑ Keep it in the dark because HCLO will decompose when exposed to light 2HClO→2HCl+O2 ↑

What are the fire-fighting methods during use?

Calcium Hypochlorite is very dangerous chemical with class 5.1, since it's very easy to catch fire. In case of fire, suggest used yellow sand, carbon dioxide, foam fire extinguishing, general sulfuric acid fire extinguishers are not allowed.
