WebThe real advantage of eucalyptus explosion pulp over conventional CMP (chemical-mechanical pulp) and CTMP (chemical-thermo-mechanical pulp) is observed when the impregnation solution contains less than 2% NaOH along with 8% Na 2 SO 3, and when the liquor/chips ratio equals 3. The strength of eucalyptus explosion pulp obtained by using a ... WebChemimechan- ical pulping and chemithermomechanical pulping (CTMP) are similar but use less mechani- cal energy, softening the pulp with sodium sulfite, carbonate, or hydroxide. Chemical pulps are made by cooking (digest- ing) the raw materials, using the kraft (sulfate) and sulfite processes.
