The role of ammonium persulfate

If ammonium sulfate sounds unfamiliar to you, then bleach probably sounds familiar to you. The bleaching agent used in daily life is ammonium persulfate, which is widely used in various fields of industry. For example, in the battery industry, it helps remove agents from batteries, and is used to remove sea waves in photography. Ammonium persulfate has also been developed in other industries. The following editor will show you the role of ammonium persulfate in detail.

1. Widely used in the battery industry; it is also used as a polymerization initiator and a desizing agent in the fiber industry;

2. It can also be used as a surface treatment agent for metals and semiconductor materials, and an etchant for printed circuits;

3. It is also widely used in oil layer fracturing in oil extraction, flour and starch processing industry, oil industry,

Used in the photographic industry to remove sea waves. For the determination and measurement of manganese, used as an oxidant. Bleach. Photographic reducers and blockers. Battery depolarizer. Used for the preparation of soluble starch.

4. It is used as an initiator for emulsion polymerization of vinyl monomers such as vinyl acetate and acrylate. It is cheap and the resulting emulsion has good water resistance. It is also used as a curing agent for urea-formaldehyde resin, with the fastest curing speed. It is also used as an oxidant for starch adhesives, reacting with the protein in the starch component to improve adhesion. The reference dosage is 0.2% to 0.4% of starch. It is also used as a surface treatment agent for copper metal.

5. In the chemical industry, it is used as a raw material for the manufacture of persulfate and hydrogen peroxide, a polymerization promoter in organic polymer polymerization, and an initiator in the polymerization of vinyl chloride monomer. Used as bleaching agent in oil and soap industry. It is also used as a corrosive agent in metal plate etching and in oil production in the petroleum industry. Food grade used as wheat modifier, beer yeast mildew inhibitor

6. Used in the manufacture of aniline dyes and as an oxidative coloring agent for vat dyes. .

7. Decolorization and bleaching of oil, washing and deodorization of spoiled yeast, and ripening agent for wheat.

8. Additives used for downhole fracturing in oil extraction. Storage and usage precautions:

Ammonium persulfate is non-flammable, but because it can release oxygen and support combustion, it must be stored under certain conditions. First of all, it must be stored in a dry, sealed container. Secondly, it should be kept away from direct sunlight, heat sources, moisture and other adverse factors. In addition, some impurities such as dirt, rust, small amounts of metals and reducing agents may cause the decomposition of ammonium persulfate, and care must be taken during storage and use. Since wet ammonium persulfate powder and its aqueous solution have bleaching and slight corrosive effects, direct contact with eyes, skin and clothing should be avoided during use.
