Sodium percarbonate is an important chemical raw material, widely used in cleaning, bleaching, oxidation and other fields. In the upstream and downstream related products of sodium percarbonate, it mainly involves the supply of raw materials, production process, application fields and so on. This article will detail the upstream and downstream associated products of sodium percarbonate.

1. Upstream Related Products

1. Sodium carbonate: Sodium carbonate is one of the main raw materials of sodium percarbonate and is used to produce sodium percarbonate.
2. Hydrogen peroxide: Hydrogen peroxide is another important raw material for sodium percarbonate, which reacts with sodium carbonate to form sodium percarbonate.

2. downstream associated products

1. cleaning agent: sodium percarbonate can be used as the main component of cleaning agent, used to remove the surface of clothing, tableware and other stains and grease. Compared with the traditional phosphorus-containing cleaning agent, sodium percarbonate has the advantages of non-phosphorus, non-toxic, environmental protection and so on.
2. bleach: sodium percarbonate has strong oxidation, can be used for bleaching fabrics, paper, etc., to make its color more white.
3. Oxidant: Sodium percarbonate can be used as an oxidant to remove iron and manganese from water and to oxidize organic matter in wastewater.
4. Desiccant: Sodium percarbonate can absorb moisture in the air and is used as a desiccant.

3. production process

sodium percarbonate production process mainly has two kinds: dry method and wet method. The dry method is to mix sodium carbonate and hydrogen peroxide, and then react under dry conditions to generate sodium percarbonate; the wet method is to mix sodium carbonate solution and hydrogen peroxide solution to generate sodium percarbonate crystals, and then through separation, drying and other processes to obtain the product.

4. Application field

Sodium percarbonate is widely used in daily chemical, textile, papermaking, environmental protection and other fields. In the field of daily chemicals, sodium percarbonate can be used as detergent and bleaching agent for laundry cleaning and fabric bleaching; in the textile field, sodium percarbonate can be used for textile pretreatment and dyeing; in the field of papermaking, sodium percarbonate can be used as bleaching agent to improve the whiteness of paper; in the field of environmental protection, sodium percarbonate can be used for wastewater treatment and air purification.

In short, sodium percarbonate is an important raw material for chemical production, and its upstream and downstream related products involve many fields and have a wide range of application prospects.
