What are the advantages of chlorine dioxide?
When we receive tap water for washing in the morning, we find that the water is turbid. After a while, we find that the water becomes clear. We all know that it is caused by bleach reagent, but is bleach safe?
In recent years, water factories have successively adopted chlorine dioxide generators. The chlorine dioxide solution produced by the generators disinfects the tap water. Chlorine dioxide is a yellow green gas with a pungent smell. It is quite stable in the aqueous solution and can be used safely as a disinfectant, so we can rest assured.
In addition, chlorine dioxide is not only a highly efficient oxidant, but also has strong decolorization and bleaching capabilities.
Chlorine dioxide can also be used to bleach textiles and pulp. It is an important and excellent sulfate pulp bleach. It has two advantages in the bleaching process. On the one hand, it is whitening and has good whiteness stability; On the other hand, it has a strong lignin removal effect to avoid serious degradation of cellulose and hemicellulose.
Domestic pulp bleaching mainly uses chlorine, hypochlorite and hydrogen peroxide. The use of hypochlorite and chlorine bleaching is prone to produce carcinogenic organic chlorides, and hypochlorous acid will oxidize cellulose at the same time, reducing the strength of the material. However, the brightness of the pulp is unstable during chlorine bleaching, and it is easy to yellowing during storage. When hydrogen peroxide is used as a bleaching agent, if there are too many metal ions in the solution to decompose hydrogen peroxide, 65% of the hydrogen peroxide may not play the role of bleaching and be effectively decomposed. Chlorine dioxide bleaching can overcome the above shortcomings. The bleached pulp has high whiteness, good whiteness stability, less viscosity reduction, high pulp yield, and few carcinogenic organic chlorides in bleaching waste liquid. Reducing the amount of elemental chlorine in bleaching process and replacing some or all chlorine with chlorine dioxide are effective measures to reduce the pollution of bleaching wastewater.
