Technical data sheet

Main Application direction

Sodium persulfate is a polymerization initiator such as latex or acrylic monomer polymerization solution, vinyl acetate, vinyl chloride, styrene, acrylonitrile, butadiene, etc. Widely used in metal surface treatment.

(1) Used for metal surface cleaning and pickling.

(2) Used to speed up the processing of low concentration formalin adhesive.

(3) is the production of starch regulator, and applied in the production of adhesive and paint.

(4) Used as a depulsing agent and bleaching agent.

(5) is one of the basic ingredients of hair dye, plays the role of decoloring.

storage

Sodium persulphate is a non-inflammable substance, but it must be stored under certain conditions because of its combustion-supporting effect due to its ability to release oxygen. 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, a small amount of metal and reducing agent may cause the decomposition of sodium persulfate, which must be paid attention to during storage and use. Direct contact with eyes, skin and clothing should be avoided due to the bleach and slight corrosion effect of wet sodium persulfate powder and its aqueous solution.
