Read： 1000 Time：20months ago Source：Transform the World with Simplicity

Sodium peroxycarbonate (2Na2CO3 · 3H2O2), also known as sodium perborate or sodium percarbonate, is an inorganic compound. It has the functions of releasing oxygen, bleaching, sterilization and deodorization, so it is widely used in washing, bleaching, food, medical and other fields. This article will introduce the manufacturing method of sodium percarbonate.

1. production raw material

sodium peroxycarbonate production raw materials mainly include sodium carbonate, hydrogen peroxide and water. Among them, sodium carbonate is an alkaline absorbent, hydrogen peroxide is an oxidizing agent, and water is used as a solvent and a reaction medium.

2. production principle of

sodium peroxycarbonate production principle is the hydrogen peroxide and sodium carbonate under certain conditions, generate sodium peroxycarbonate crystal. The reaction equation is:

2 Na2CO3 3H2O2 → 2 Na2CO3 · 3 H2O2

3. Production process

1. Ingredient

Add sodium carbonate, hydrogen peroxide and water into the ingredient tank according to a certain proportion, and stir evenly.

2. reaction

the mixture in the mixing tank is pumped into the reactor, and the reaction is carried out at a certain temperature and pressure to generate sodium peroxycarbonate crystal.

3. Crystallization
After completion of the
reaction, the reaction solution was pumped into a crystallizer to carry out crystallization. A stirring device is arranged in the crystallizer to promote the formation and growth of crystals.

4. Centrifugal separation

After the crystallization is completed, the crystallization solution is pumped into a centrifuge and centrifuged to obtain sodium percarbonate crystals and a mother liquor.

5. Drying

The sodium percarbonate crystals are sent to a dryer and dried to obtain a dry sodium percarbonate product.

4. precautions

1. Control the reaction temperature and pressure to ensure the smooth progress of the reaction.

2. Crystallizer should be equipped with appropriate stirring device to promote the formation and growth of crystallization.

3. Centrifugation speed and time should be controlled during centrifugal separation to avoid crystal breakage and mother liquor residue.

4. When drying, control the drying temperature and time to avoid overheating and decomposition of the product. Summary of

5. The manufacturing method of

sodium percarbonate mainly includes ingredients, reaction, crystallization, centrifugal separation and drying steps. In the production process, it is necessary to pay attention to the control of process parameters such as reaction temperature and pressure, crystallization and drying to ensure product quality and output.
