what is timber used for

These are made from pulp, saw- mill waste, such as sawdust, or forest waste, such as chips and offcuts. Timber also can be fabricated into structurally engineered wood products that are suitable for sustaining high loads, substituting for other materials such as steel I-beams. The rayon so produced is called acetate. Timber is the most important element used for making furniture. Timber Uses The versatility of timber means that it has a broad range of uses in today’s society. The oils and other extracts from timber are used in the creation of products including paints, resins, and gum. This is a simple and fairly cheap process but has some disadvantages. The African and South American continents consume a very large proportion of their timber as fuel, both for domestic and indus­trial purposes, and in fact most tropical countries have a high consumption. The rayon fila­ments may be used as they are to produce ‘artificial silk’ or may be cut into staple lengths and then spun, woven, dyed and finished in the same way as ordinary textiles. There is also widespread use in timber home construction, where the characteristic of this style is the use of timber that is generally greater than 5 inches in size. Construction 3. For this reason it is particularly important in the U.S.A. where much of the timber production is of very resinous pines from the southern states. Both fibreboard and particle board production are increasing and should be encouraged because they can make use of hitherto wasted timber materials and at the same time can ease the demand for sawn-timber in the construction indus­try. The U.S.A., Japan and European countries such as Italy are the major rayon producers. Various types of timber have a wide range of uses as dyestuffs, chemicals and so on but many of these applications have been superseded by the development of synthetic chemical dyes and resins.

Sawnwood, mostly from coniferous trees, is also used in the form of planks, boards, beams and so forth in house building. Website Last Modified November 29, 2020. Canada uses less than 5 per cent of its timber for fuel. Trees also yield tannin, gums, resins and drugs. Paper for books, magazines, newspapers, and other printed items like brochures, flyers, and marketing materials, as well as copy paper, envelope paper, kraft paper, parchment paper, packaging paper, and photographic paper all are ultimately derived from timber. Wood cellulose is the basis of the synthetic textiles known as rayon. Lumber or timber, a wood which is capable of yielding the minimum size of a dimension, is generally produced from growing woods. The U.S.A. derives about 10% of its pulp by the semi- chemical process, and is the largest producer of semi- chemical pulp. Another process, using acetic acid, acetic anhydride and acetone produces a solu­tion which is extruded into a current of warm air rather than a coagulant.

The low consumption of timber as fuel in North America reflects both the availability of a wide range of other fuels and the high standard of living. Timber has a fast growth rate with softwood varieties able to replenish at a faster rate than hardwoods. Fibreboard is made mostly from mechanically or semi-chemically processed pulp and both softwoods and hardwoods can thus be used. The following points highlight the top five uses of timber. In addition to sawn timber and processed woods such as plywoods, timber is also used in the form of fibre- and particle- boards. The greater importance of the packaging industry in the U.S.A. is another reason for this concentration. Timber is a renewable resource and is grown in countries around the globe. Most timber used for construction, pitprops, matches and so on is softwood. There are three processes by which wood is con­verted into pulp and the method used depends on the type of wood and the type of paper to be pro­duced: About one-fifth of the world production of woodpulp is produced by the mechanical process, in which the wood is ground up by revolving grindstones and then soaked in water to produce a fibrous mass. These types of board, such as hardboard, blockboard, chipboard, etc. Timber is an important source of fuel, where its combustion can be used to heat homes, provide energy for cooking food, and heat water for domestic use. Pit-props, however, are usually of coniferous logs. Those countries which are short of timber, such as Britain, but have ample supplies of coal and gas, use very little timber for fuel.

Timber stores the excess carbon that is removed from the atmosphere and continues to do so or the duration of its existence. Much forest waste is utilized in its production. are used for furniture and internal construction work such as linings, ceilings and so on. After fuel the most important use for timber is in the building and constructional industries. Timber has good thermal insulating properties and can reduce the energy use of homes when the material is used in doors and windows. Privacy Statement and Fuel 2. The sulphite process, in which calcium bisulphite is used at high temperature and pressure, produces pulp for book papers and high- quality papers, but requires less resinous woods.
