Sodium Percarbonate-Sodium Percarbonate (Synonyms: Sodium Carbonate Peroxyhydrate, sodium carbonate peroxide, PCS) is a free-flowing powder with a common name of solid hydrogen peroxide, Sodium Percarbonate is an addition compound of sodium carbonate and hydrogen peroxide. We can produce 100000MT Sodium Percarbonate per year.
Sodium Percarbonate (Synonyms: Sodium Carbonate Peroxyhydrate, sodium carbonate peroxide, PCS) is a free-flowing powder with a common name of solid hydrogen peroxide, it is an addition compound of sodium carbonate and hydrogen peroxide. Percarbonate has an active available oxygen content which is equivalent to 27.5% H2O2. It breaks down to oxygen, water and sodium carbonate upon decomposition. It's an environmentally safe bleaching agent. Sodium Percarbonate can be mixed with one of the compounds containing polyvinyl alcohol (PVA) and copper, ferrum, cobalt, manganese, and so on. In emergence, adding some water to this mixture, oxygen will be released in a ready and large quantity way.
Sodium Percarbonate offers many of the same functional benefits as liquid hydrogen peroxide. It dissolves into water rapidly to release oxygen and provides powerful cleaning, bleaching, stain removal and deodorizing capabilities. As Sodium Percarbonate is a kind of new high effective bleaching raw material for detergent, with advantage of no odor, no toxin, and no pollution. Due to the bleaching capacity of active oxygen released into the water, Sodium Percarbonate shows well performance. Sodium Percarbonate also is one disinfecting agent,it can kill coliform, staphylokinase, hepatitis bacterium and so on, therefore it is used as defecting agent in Hospital,Public Place,and to disinfected Medical Instrument, False Teeth, Fruit tools and Fruite and so on. Along with the development of aquiculture, usages of Sodium Percarbonate in such domains are increasing. Many detergent manufacturers home and abroad have being adopted Sodium Percarbonate as bleaching raw material instead of Sodium perborate or others.
