| Uses | Pulp and paper, construction, packaging and
cooperage, furniture, destructive distillation products
(charcoal), extraction products (turpentine,
rosin, tall oil, pine oil, etc.), methanol, plywood,
fuel, rayon and cellophane, flock. | | Definition | A mixture composed of 67–80% holocellulose and 17–30% lignin, together with low percentages of resins, sugars, a variable amount of water, and potassium compounds. Its fuel value varies widely around 3000–6000 Btu/lb according to variety, moisture, etc. Combustible. | | Agricultural Uses | Wood is a hard, dead tissue obtained from the trunks and
branches of trees and shrubs. Woody tissue is also found
in some herbaceous plants.
Botanically, wood consists of xylem tissue which is
responsible for the conduction of water around the plant.
A living tree trunk is composed of (beginning from the
carter) the pith (remains of the primary growth), wood
(xylem), cambium (a band of living cells that divide to
produce new wood and phloem), phloem (conducting
nutrients made in the leaves), and the bark. The wood
nearest to the cambium is termed sapwood because it is
capable of conducting water. However, the bulk of the
wood is heartwood in which the xylem is impregnated
with lignin, which gives the cells extra strength but
prevents them from conducting water in temperate
regions. The age of a tree can be found by counting its
annual rings. Commercially, wood is divided into
hardwood (from deciduous angiosperm trees) and
softwood (from gymnosperms). Wood is mainly used in
paper and pulp industry, construction, furniture making,
rayon and cellophane manufacture. It is also used in
places as domestic fuel for cooking. The fuel value varies
widely around 7000 to 14OOO J/g according to the wood
variety, moisture content, etc.
Wood is a mixture of three natural polymers
cellulose, hemicellulose and lignin. Chemicals derived from wood include bark products, cellulose, cellulose
esters, cellulose ethers, charcoal, dimethylsulphoxide,
ethyl alcohol, fatty acids, furfural, hemicellulose,
haft lignin sulphonates, pine oil, rayons, resin, sugars,
tar oil, turpentine and vanillin. Most of these are
direct products or by-products of wood pulping, in which
the lignin, that cements the wood fibers together and
stiffens them, is dissolved away from the cellulose. The
other materials developed from wood are solid wood
products (including lumber, veneer and plywood
laminated timbers, insulation board, hardboard and
particle board) and fiber wood products (paper and
paperboards) |
