Sodium Perborate

Sodium Perborate monohydrate  and Sodium Perborate Tetrahydrate (Synonyms: sodium peroxyborate, sodium peroxoborate, PB1) is similar to sodium percarbonate as a famous oxygen bleach agent. Sodium perborate offers many of the functional benefits as liquid hydrogen peroxide in a stable solid form. The oxidative power of sodium perborate improves the cleaning, bleaching, stain removal and deodorizing performance of powder detergent formulations, all fabric dry bleaches, denture cleaners, automatic dishwasher detergents and various institutional and industrial laundry products.


After reacting and seperating from the saturated solution, the crystalline of sodium perborate tetrahdyrate is obtained, we only need to put them through a normal fluid bed dryer at lower temperature, the commodity of sodium perborate tetrahydrate is obtained easily. but in order to get sodium perborate monohydrate by dehydrating sodium perborate tetrahydrate, we have to use an unique designed fluid bed dryer. The monohydrated sodium perborate is essentially showing three advantages in comparison with the tetrahydrated sodium perborate: a higher content of available oxygen, a higher heat stability and a higher dissolution rate into water. It provides a high available oxygen content equivalent to 32% hydrogen peroxide - 50% more active oxygen than the same weight of sodium perborate tetrahydrate. Sodium perborate releases nascent oxygen at elevated temperatures, it is a stable, solid source of active oxygen.


Sodium perborate will decompose in the environment to natural borate. Although boron is an essential micronutrient for healthy growth of plants, it can be harmful to boron sensitive plants in higher quantities. Care should be taken to minimize the amount of borate product released to the environment.


A lot of applicaiton using borax, or sodium metaborate can be replaced by sodium perborate very well, as it combine the function of borax providing boron ring, but more concentrated, it is widely used for some production process of adhensive industry, also it is an important chemcials for hydranlic fracturing for shale gas drilling which can maintains fluid viscosity as temperature increases as well delayed breaker
