Sodium Percarbonate Usage and Synthesis.

Sodium percarbonate has high efficient washing ability, adding sodium percarbonate oxygenated detergent can make the effective composition of the detergent greatly improved, can effectively remove the general laundry detergent can not remove fruit stains, wine stains, yellow stains, etc., and at the same time, it can effectively reduce the amount of detergent, to achieve the effect of energy saving and reduction of consumption.

In addition to excellent functional characteristics, sodium percarbonate is also an environmentally friendly new material, the decomposition of sodium percarbonate oxygen, water and sodium carbonate are naturally occurring substances that have no adverse impact on the environment. Therefore, sodium percarbonate is an efficient, energy-saving, environmentally friendly oxygen bleaching additives, in line with the development trend of modern detergents, has been widely used in the washing industry. Meanwhile, sodium percarbonate can also be used in environmental protection, printing and dyeing, paper making, medical and other fields.

As a representative of high-efficiency oxygen bleaching agent, with its excellent bleaching activity and bactericidal properties, sodium percarbonate has been widely used in the fields of washing (washing powder and color bleaching powder, etc.), printing and dyeing, textile, papermaking, medicine and health care, household and personal care product formulations, etc.

Uses of Sodium Percarbonate.

Sodium percarbonate is a compound made by the reaction of sodium carbonate and hydrogen peroxide, which is odorless, non-toxic, easy to dissolve in cold water, strong in decontamination, and can release oxygen after dissolving in water to bleach and sterilize. In daily life, sodium percarbonate is widely used in washing, bleaching, sterilization and other fields.

Specific uses include:

1. stain remover: it can remove oil stains, dirt and other pollutants that are difficult to clean, and it is an important ingredient of many detergents;

2. bleaching agent: with strong redox capacity, it is used to bleach textiles, paper, wood and so on;

3. Oxygenator: used to increase oxygen in fish pond in three dimensions and purify water quality. Sodium percarbonate is lower in cost and better in solubility than sodium perborate, which is an important direction for the development of detergents. In addition, sodium percarbonate is also widely used in chemical and pharmaceutical fields.

Preparation of Sodium Percarbonate.

Dry production process - Sodium peroxycarbonate crystals are produced by spraying hydrogen peroxide solution on anhydrous sodium carbonate in a fluidized bed of boiling hot air. Although the production process is simple, but the product stability is poor, low content of active oxygen, as well as the production technology and process conditions are strict, difficult to operate and other reasons, the industry is rarely used.

Wet production process - the reaction of hydrogen peroxide aqueous solution with sodium carbonate in the presence of stabilizer, control the reaction temperature below 5 ℃, then add salting out agent to make sodium peroxycarbonate crystallization, centrifugal separation, air drying, that is, the finished product of sodium peroxycarbonate.

This method produces products with good stability and mature technology, and is widely used in industry. At present, there are spraying method, low temperature crystallization method and solvent method for production.

Product Method of Sodium Percarbonate.

Produced by electrolysis of hydrogen peroxide aqueous solution with magnesium silicate and sodium silicate as a stabilizer, after cooling, add sodium carbonate neutralization, and add sodium oxide, after the end of the reaction will be precipitated crystals after centrifugal separation and airflow drying and become.
