Potassium persulfate Usage:
1.Polymerization: initiator of latex or acrylic monomer polymerization liquid, vinyl acetate, vinyl chloride and other products, and initiator of copolymerization of styrene, acrylonitrile, butadiene and other colloid.
2.Metal treatment: treatment of metal surfaces (e.g. in semiconductor manufacturing: cleaning and etching of printed circuits). Activation of copper and aluminum surfaces.
3.Cosmetics: the main ingredient of bleaching formula.
4.Textiles: desizing and bleaching agents – especially for low temperature bleaching.
5.Others: chemical synthesis.
6.Water treatment (purification).
7.Waste gas treatment, oxidative degradation of harmful substances (e.g. mercury);
8.Disinfectant;
Storage: Potassium persulfate is a non-flammable product, but because it can release oxygen and has a combustion effect, storage, must be stored in a dry, airtight container, avoid direct sunlight, not near the heat source. Do not contact with organic matter and rust, a small amount of metal and other reducing substances, to prevent the decomposition of potassium persulfate, explosion. Due to the bleaching and slight corrosion of the wet potassium persulfate powder and its aqueous solution, direct contact with eyes, skin and clothing should be avoided during use.
