Potassium permanganate ball is a deep-processed product of activated alumina, which is made of special activated alumina carrier, pressurized by high-temperature solution, depressurized and other processes, and it has more than twice the adsorption capacity of similar products and the characteristics of high strength and long life.
Using the strong oxidizing property of potassium permanganate, formaldehyde can be oxidized to carbon dioxide and water. It can also oxidize and decompose the harmful gases in the air with reducing property, so as to purify the air. It has high removal efficiency for harmful gases such as hydrogen sulfide, sulfur dioxide, chlorine, formaldehyde and nitric oxide.
The content of potassium permanganate ball can be produced according to customers' requirements, at present, the commonly used content is 4%, 6%, 8%, 10% and so on.
