Magnesium Hydroxide for Pulp Bleaching

Magnesium hydroxide functions as a cellulose protector and an alkali in mechanical pulp peroxide bleach systems, as well as in the oxygen delignification and extraction stages of chemical pulp bleaching. magnesium hydroxide has multiple applications in pulp bleaching and provides the following benefits:

Features

Mechanical Pulp Bleaching	Chemical Pulp Bleaching
Significantly lowers bleach chemical costs by eliminating or reducing caustic soda and sodium silicate usage and by yielding higher residual peroxide for potential reuse	Reduces chemical costs by eliminating magnesium sulfate usage in oxygen delignification and extraction stage bleaching
Reduces potential for silicate scaling and oxalate scaling	Lowers caustic soda, peroxide and/or chlorine dioxide usage in chemical pulp bleaching
Lowers BOD/COD up to 40%	Maintains brightness and physical properties
Improves pulp yield as indicated by BOD/COD reduction
Reduces anionic trash as measured by conductivity up to 40%
Maintains brightness and physical properties
