Enzymatic Bleaching of Wood Pulp

The dark colour of kraft pulp after the wood chips have been heated at high temperature with NaOH solution is caused by lignin (a complex phenolic polymer) still attached to the cellulose fibres. Traditionally this pulp is treated with chlorine to bleach the pulp to make it suitable for paper making. Unfortunately this leads to the formation of some potentially toxic chlorophenolic compounds of...

comparison of lbl nanotechnology and refining on the properties of pulp and paper made from recycled fibers

in this study, in order to constitute polyelectrolyte multilayers (pem) using layer-by-layer nanotechnology, recycled fibers were subsequently treated with cationic starch (cs) and anionic starch (as) multi-layers each layer conducted at neutral ph for 10 minutes. also, to compare with mechanical of refining, the pulp was refined for 25 minutes to the freeness of about 291 ml.csf using valley b...

Characteristics of Particleboard Made from Sedar Chips and Wood Slabs (TECHNICAL NOTE)

This study was Characteristics of manufacture particleboard (PB) from sedar and wood slab of impregnated with UF. The chips were divided into coarse chips with dimensions of 2-4 mesh and fine chips of 30–60 mesh, urea formaldehyde (UF) resin solution at concentrations of 45 %, and 55% sprayed on these chips about 1 min until 10% to dry weight chips, they were dried under 5% moisture in a dram d...
