Percarbonic acid is abbreviated as SPC or PCs. Commonly known as solid hydrogen peroxide, it is an addition compound of hydrogen peroxide and sodium carbonate. Its effective active oxygen content is equivalent to 29% hydrogen peroxide. Sodium percarbonate not only has the function of liquid hydrogen peroxide, that is, it can quickly decompose and release reactive oxygen species at low water temperature, so as to realize the functions of bleaching, decontamination, sterilization, deodorization, oxygenation and so on. The sodium carbonate produced at the same time can improve the pH value of water and improve the bleaching and washing effect. It has been widely used in all kinds of industrial and civil products. He is increasingly replacing sodium perborate in washing (washing powder, color bleaching powder, etc.), printing and dyeing, textile, papermaking and other fields; At the same time, it can also be made into all kinds of oxygen supply agents and disinfectants for fish pond water supply, industrial wastewater treatment, medical disinfection / first aid, etc. it has become an important raw material for international environmental protection cleaning products. Compared with encapsulated sodium percarbonate, non encapsulated sodium percarbonate has the characteristics of high reactive oxygen species and fast oxygen release rate. It is more suitable for the production of bleaching powder, color bleaching powder and oxygen enhancer.
