Definitions
- the present invention relates to a multi-component system for changing, breaking down or bleaching lignin or containing lignin Materials and procedures for its Application.
- the sulfate and sulfite processes are the main processes used today for pulp production. Both methods produce pulp under cooking and under pressure.
- the sulfate process works with the addition of NaOH and Na 2 S, while the sulfite process uses Ca (HSO 3 ) 2 + SO 2 .
- the main goal of all procedures is the removal of the lignin from the used plant material, wood or Annual plants.
- the lignin that is associated with cellulose and hemicellulose Main component of the plant material must be removed, otherwise it is not possible non-yellowing and mechanically heavy-duty papers to manufacture.
- the wood production processes work with stone grinders (Wood sanding) or with refiners (TMP), which the wood after appropriate Pretreatment (chemical, thermal or chemical-thermal) defibrillate by grinding.
