To use:
Used for desizing agent and bleaching active agent
Used for water tank and closed circulation treatment of harmful substances in the water oxidation degradation
Is the production of starch regulator, and used in the production of adhesive coatings
Used for branched chain oxidation, ethanol and aromatic hydroxyl oxidation
One of the basic ingredients of hair dye, which plays a decolorizing role
Storage and notes
Potassium Persulfate is a non-combustible, but because it can release oxygen and can play an auxiliary role, and therefore must be stored under certain conditions. Firstly, it must be stored in a dry and airtight container. Secondly, it should avoid direct sunlight, heat source, humidity and other adverse factors. In addition, some impurities, such as dirt, rust, small amounts of metal and reducing agent can cause the decomposition of Potassium persulfate, and attention must be paid in the storage and use of Potassium persulfate. Because Potassium persulfate powder and its water solution are bleached and slightly corrosive, direct contact with eyes, skin and clothing should be avoided during the administration.
