Перкарбонат натрия

I.Brief introduction Sodium percarbonate (Formula : 2Na2CO3.3H2O2) ,it is an addition of sodium carbonate and Hydrogen peroxide.Also named as solid hydrogen peroxide .But it is more easier to be used and storied than hydrogen peroxide. When meet water,SPC will release oxygen and sodium carbonate. Sodium 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 provides powful cleaning,bleaching,stain remove ,deodorizing and disinfecting capabilities.It is a new oxygen bleaching agent,used as the raw material for washing powder with little or no phosphor,as potching agent and reductive chromogenic agent in textile industry,as well as used as other agents.Our sodium percarbonate with high stability has a wide range of applications in various cleaning products and detergent formulations including heavy duty laundry detergent, all fabric bleach, wood deck bleach, textile bleach and carpet cleaner. Other applications have been explored in personal care formulations, denture cleaners, pulp and paper bleaching process, and certain food bleaching applications. The product also has functions as disinfector for institutional and home applications, oxygen releasing agent in aquaculture, waste water treatment chemical, first-aid oxygen generating agent, etc. Sodium percarbonate is used as an activated oxygen component in detergents, bleaches and cleaning agents. Since the unsatisfactory storage stability of the uncoated sodium percarbonate in warm or moist circumstance and in the presence of certain detergent and cleaning agent components, percarbonate must be stabilized against the loss of active oxygen. An essential principle of stabilization involves encasing the percarbonate particles in a coating of components having a stabilizing action. Here comes the definition: the coated sodium percarbonate is the crystals coated with single or multiple layers of various substances in order to increase active oxygen stability and optimize storage and ensiling properties. Coated sodium percarbonate is the more commonly commercialized peroxide compared with the uncoated type. But the uncoated product is still the preferred ingredient for simply mixing with enough quantity of soda ash and some surfactants to form the popular oxygen bleaches. Compare with other bleaching product such as chloride bleaching product and Sodium perborate,Sodium percarbonate has many advantages,It is odorless and envirment friendly,when solute in water,there is no leftover.Also it can active in not high temperature condition,thus can save much energy. Sodium percarbonate is a new raw material for detergent.Now more and more detergent manufacturer are using this material.Each year,its quantity of consumption are increasing by 1.5times every year.Its a long life product,has bright market potential.
