Summary of performance

Ammonium persulfate is a kind of white single crystal with a density of 1.98, which is completely decomposed at 120°C. When completely dried, it can be preserved for a long time without decomposition and is not easy to absorb moisture. However, after absorbing moisture, it will gradually decompose and release oxygen and ozone. Soluble in water and decomposed by heat. Strong oxidation, can be used as chemical reagent, oxidant, bleach, deodorant, monomer polymerization initiator. It also has the advantages of easy to use and safety.

storage

Ammonium persulfate is non-inflammable, but it has combustible-supporting effect because it can release oxygen, so it must be stored in a dry and airtight container to avoid direct sunlight and heat source. Do not contact with organic matter and rust, a small amount of metal and other reducing substances, in order to prevent the decomposition of ammonium persulfate, explosion. Because the wet ammonium persulfate powder and its aqueous solution have bleaching and slightly corrosive effects, direct contact with the eyes, skin and clothing should be avoided during use.

application

Polymerization: the initiator of latex or acrylic monomer polymerization solution, vinyl acetate, vinyl chloride and other products, but also styrene, acrylonitrile, butadiene and other colloidal copolymerization initiator.

Metal treatment: treatment of metal surfaces (e.g., in semiconductor manufacturing: cleaning and etching of printed circuits). Activation of copper and aluminum surfaces.

Cosmetics: essential ingredient in bleaching formulations.

Textiles: Depulsing agents and bleaches - especially for low temperature bleaching.

Other:

Chemical synthesis;

Water treatment (purification);

Waste gas treatment, oxidative degradation of harmful substances (e.g. mercury);

Disinfectant;

Paper (starch modified for low temperature bleaching special repulsing).
