Magnesium hydroxide in the pulp and paper industry
BleachMag® protects cellulose and fibers in mechanical pulp peroxide bleaching and in delignification during chemical pulp bleaching. BleachMag® is a new and efficient reagent based on natural magnesium hydroxide Mg(OH)2. It effectively replaces soda ash Na2CO3, caustic soda NaOH, caustic magnesia MgO, sodium silicate Na2SiO3 and magnesium sulfate MgSO4. BleachMag® improves efficiency as well as product quality and reduces process costs.
Economic savings Production advantages Environment benefits
- Lower bleaching cost
- Lower waste water treatment cost
- Higher pulp yield
- BleachMag® acts as alkali and magnesium source
- The liquor preparation and the process itself becomes simpler
- The pH in pulping remains more stable
- Drastic reduction of oxalate scaling
- Improved settling properties of the waste water sludge
- Reduced TOC, COD and BOD.
- Safe and easy storage and use
- Lower chlorine content of BleachMag® compared to competitors
BleachMag® requires no major changes or investments at the pulp, paper, or board mill. Russian Mining Chemical Company, RMCC, provides BleachMag® as a powder or a 50 % stabilized aqueous dispersion.
BleachMag® can be used in sulphite and bisulphate pulping to replace both caustic magnesite, and soda ash or lime. The replacement of soda ash with BleachMag® powder reduces the consumption of chemicals some 30 %.Chemical pulp bleaching
BleachMag® reacts as an alkali source and cellulose protector in chemical pulp bleaching. BleachMag® slurry contains both hydroxyl ions OH- and magnesium ions Mg2+, so it can replace magnesium sulfate MgSO4, and substitute partially caustic soda NaOH, in chemical pulp bleaching. It has been proved in laboratory and mill that BleachMag® slurry is a cost effective option.Mechanical pulp bleaching
In bleaching of mechanical pulps, BleachMag® reacts as a stabilizer and an alkali agent. BleachMag is a cost effective alternative to caustic soda and sodium silicate. BleachMag® can be used in all GW, PGW, RMP, TMP, and CTMP high yield mechanical pulp mills. BleachMag® slurry can also improve pulp strength and paper machine retention.Packaging
