Category: Water Treatment; Bleach and oxidant
Application:
1. Used for bleaching of pulp, fiber, flour, starch, grease, water purification and sewage treatment, leather hair removal and preparation of chlorine dioxide aqueous solution, etc. For high efficiency bleach and oxidant. Mainly used for pulp, paper and various fibers, such as cotton, hemp, reed. The bleaching of viscose fiber can also bleach sugar, flour, starch, grease and wax. Also used for leather hair removal, some metal surface treatment, water purification and sewage treatment. It can be used as an extraction agent for indusarin staining. Oxidant. Fungicide. Purified water. Bleach for fabric.
2. Used as a bleaching agent in the food industry. Mainly used for sugar products. The aqueous solution of sodium chlorite has stable bleaching ability under acidic conditions, and can be bleached by adding citric acid to adjust pH to 3-5. Bleaching with corrosion resistant containers, do not use metal containers. Japanese regulations limit the use of cherries, honeydew, grapes and peaches.
3. Highly efficient bleach and oxidant. It is mainly used to bleach pulp, paper and various fibers, such as cotton, hemp, reed and viscose fiber, as well as white granulated sugar, flour, starch, grease and wax. Also used for leather hair removal, some metal surface treatment, water purification and sewage treatment. It can be used as an extraction agent for indusarin staining.
4. Used for drinking water purification, no residual chlorine odor treatment of sewage with sterilization, phenol removal, deodorization. This product is also an efficient bleaching agent, used to bleach fabric, fiber, pulp, with the characteristics of small fiber damage.
5. Used for sterilization of oil well system;
6. Desulfurization and denitration treatment of power plants and steel mills.
