Comparison of pearl oyster shell powder disinfectant water and chlorine disinfectant water.
Chlorine disinfectant water (chlorine dioxide, hypochlorous acid water, hypochlorite (sodium), etc.).
Although it has a bactericidal effect, it is not easy to store. It will quickly decompose when exposed to light and heat, and it will produce chlorine pungent.
In addition, chlorinated disinfectant water is only for immediate sterilization, and cannot create an alkaline environment during sterilization.
Pearl oyster shell powder is a natural material, sterilization will also create an alkaline environment, which is not good for bacterial growth.
 
Why use pearl oyster shell and other applications?
After the pearl oyster shell is calcined, the material becomes soft, easy to powder into sub-micron particles and porous.
It can be applied to disinfectant, disinfectant, vegetable and fruit detergent and deodorant.
The water quality of the breeding farm is regulated, and the foot disinfection water is used at the entrance of the pig farm and the chicken farm.
Just buy quicklime, why buy pearl oyster shell powder?

Generally, the raw material source of quicklime is mainly limestone (limestone) calcined into calcium oxide at high temperature.
However, in addition to calcium carbonate, limestone also contains a considerable proportion of carbonate and silica components, such as magnesium carbonate. Therefore, the purity of calcium oxide is not high (80%).
The pearl oyster shell contains 95% calcium carbonate, and the calcium oxide produced after calcination is of high purity.
