Pulp bleaching
BleachMag® magnesium hydroxide is is an alkaline additive made of milled brucite mineral; it is used for bleaching of pulp.
BleachMag® functions as an alkali, a stabilizer of hydrogen peroxide and a protector of cellulose in chlorine-free bleaching of pulp. It can be used for bleaching mechanical, thermomechanical, chemical-thermomechanical, chemical pulp, and waste paper (DIP). It replaces more expensive alkalis at the hydrogen peroxide bleaching stage, delignification and extraction with oxygen and alkali (stages Eop, P, Ep, E). It allows 100% replacement of magnesium sulfate (MgSO4) at oxygen delignification of cellulose.
Customers can prepare a diluted suspension of BleachMag® from the powder and water.
