application area
1. Sodium percarbonate has been widely used as washing, bleaching and bactericide in household and industry, and it is used in the production fields of synthetic fiber, animal fiber, synthetic resin fiber, pulp grease and so on, with good bleaching effect, no damage to fabric and no yellowing.
2. It can also be used in chemical, metallurgical and other departments. The use of heavy soda ash can reduce alkali dust flying, reduce raw material consumption, improve working conditions, improve product quality, reduce the corrosion of alkali powder on refractories and prolong the service life of kiln.
3. Used in food industry, as neutralizer and leavening agent, it can also be added into pasta to increase elasticity and ductility.
4. Sodium percarbonate can replace calcium peroxide as oxygen producer in aquaculture, and its oxygen release rate is obviously higher than that of calcium peroxide, which can provide oxygen for fish, shrimp, crab and other organisms during storage and transportation.
Extended data:
1, preparation method
Sodium percarbonate is an unstable compound, which forms hydrogen bonds with sodium carbonate, hydrogen peroxide and water. Because sodium percarbonate is easy to decompose at high temperature, the reaction must be carried out at low temperature. Generally, the following reactions will occur in solution:
Main reaction:
Side effects:
2. Fire extinguishing method
(1) Evacuate all irrelevant personnel immediately.
(2) Wear protective equipment and self-contained breathing apparatus.
(3) Keep the air flowing and discharge toxic gases and decomposition products.
(4) Spray with plenty of water.
