Description
Potassium perfsulfate is a white crystalline,odourless salt with the density of 2.477.It can be decomposed about 100C and dissolved in the water not in ethanol,and has strong oxidation.It is used to produce detonator,bleacher,oxidant and initiator for the Polymerization.It has the particular advantage of being almost non-hygroscopic,of having a good storage stability in normal temperature and of being easy and safe to handle.
Application
polymerization : Initiator for the emulsion or solution Polymerization of acrylic monomers,vinyl acetate,vinyl chloride etc.and for the emulsion co-polymerization of styrene,acrylonitrile,butadiene etc.
Metal treatment : Treatment of metal surfaces(e.g. in the manufacture of semiconductors;
cleaning and etching of printed circuits),activation of copper and aluminium surfaces.
Cosmetics : Essential component of bleaching formulations.
Paper : modification of starch,repulping of wet - strength paper.
Textile : Desizing agent and bleach activator - particularly for cold bleaching.(i.e.bleaching of Jeans).
Others :
- Chemical synthesis
- Water treatment(decontamination)
- Waste gas treatment,oxidative degradation of harmful substances(e.g.Hg)
- Disinfectant
