Sodium percarbonate, commonly known as solid hydrogen peroxide, is a classic chemical product that has been industrially produced in European and American countries as early as the beginning of the last century. With the development of social needs, especially the growth of ecolo

1. Aquaculture pond oxygenation

sodium percarbonate granules are an addition of hydrogen peroxide and sodium carbonate The combined crystal particles dissolve in water to generate oxygen and sodium carbonate. Generally, the average particle size of commercially available products is around 800um, the content of active oxygen is more than 13%, and the oxygen release time is 0.5-1 hour. Sodium percarbonate particles are mainly used for aquaculture oxygenation and pond hypoxia first aid.

There is also a sodium percarbonate tablet, which is made by mixing sodium percarbonate with certain sustained-release agents, release agents and fillers and pressing them into 1cm-sized tablets. It is easy to spread and can quickly sink to the bottom of the pool and dissolve to release oxygen. Generally, commercially available products contain about 50-90% sodium percarbonate, with mostly active oxygen content around 10%, and the oxygen release time can reach 24 hours.

2, detergent additives

At present, sodium percarbonate has been widely used in detergents in my country, and sodium percarbonate is combined with other effective additives to produce efficient stain removers, color bleaching powder and explosive salt . Oxygen Bleaching Powder and Explosive Salt were popular products promoted by micro-businessmen in the past few years. Due to the epidemic in the past three years, promotion of offline gatherings has been blocked. With the rise of mobile Internet and , they have become "Internet celebrity hot products" for live streaming. Sodium percarbonate has a good cleaning effect and can intuitively display the demonstration effect. It has immediate effects on making tea sets and shoes, which is why consumers readily accept it.

In addition, sodium percarbonate is also used in washing machine tank cleaning agent . With the improvement of residents' living standards, washing machine tank cleaning agent has been gradually recognized by everyone after it was introduced into my country from Europe and the United States. More than 50% of its main component is sodium percarbonate. Since it is also mixed with other surfactants or antibacterial additives, it is particularly important to coat the surface of sodium percarbonate with a film to enhance the stability of active oxygen.

In addition, sodium percarbonate is also widely used in the chemical reaction of special sandalwood, peracetic acid disinfection, textile printing and dyeing pretreatment agent, Oxylide artificial oxygenation, mine first aid oxygen, etc.

A product has a wide range of applications, and there are many things that are fake. So how much does sodium percarbonate cost per ton to be genuine?

Judging from the above chemical reaction formula, combined with the actual production situation of domestic factories, the production of one ton of highly stable phosphorus-free wrapped sodium percarbonate requires about 750kg of light soda ash and about 1000kg of 35% industrial hydrogen peroxide. In addition to other reaction aids, expenses and necessary gross profit, a total of 2000 yuan/ton costs constitute the normal cost. For example, now light pure Alkali is basically stable at 2,800 yuan/ton when it arrives at the factory, 35% hydrogen peroxide is 1,300 yuan/ton, and sodium percarbonate is 5,400 yuan/ton including tax when it leaves the factory. Of course, the price will also fluctuate depending on supply and demand, and the quality. If the fluctuation exceeds 8%, we have reason to doubt whether it is genuine, because as a low value-added product with a factory production capacity of up to 180,000 tons/year, its gross profit margin does not exceed 8%. Only when you know how to do the math yourself will you have confidence and can you buy the genuine product that you want.
