Fibreboard
Fiberboard (American English) or fibreboard (British English) is a type of engineered wood product that is made out of wood fibers. Types of fiberboard (in order of increasing density) include particle board or low-density fiberboard (LDF), medium-density fiberboard (MDF), and hardboard (high-density fiberboard, HDF). It is sometimes used as a synonym for particle board, but particle board usually refers to low-density fiberboard. Plywood is not a type of fiberboard, as it is made of thin sheets of wood, not wood fibers or particles. Fiberboard, particularly medium-density fiberboard, is heavily used in the furniture industry. For pieces that will be visible, a veneer of wood is often glued onto fiberboard to give it the appearance of conventional wood. In the packaging industry, the term "fiberboard" is often used to describe a tough kraft-based paperboard or corrugated fiberboard for boxes. "Fiberboard" is also an intermediate product, an output of a pulp mill used as input ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineered Wood
Engineered wood, also called mass timber, composite wood, man-made wood, or manufactured board, includes a range of derivative wood products which are manufactured by binding or fixing the strands, particles, fibres, or veneers or boards of wood, together with adhesives, or other methods of fixation to form composite material. The panels vary in size but can range upwards of and in the case of cross-laminated timber (CLT) can be of any thickness from a few inches to or more. These products are engineered to precise design specifications, which are tested to meet national or international standards and provide uniformity and predictability in their structural performance. Engineered wood products are used in a variety of applications, from home construction to commercial buildings to industrial products.

Medium-density Fiberboard
Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. MDF is generally denser than plywood. It is made up of separated fibres but can be used as a building material similar in application to plywood. It is stronger and denser than particle board. The name derives from the distinction in densities of fibreboard. Large-scale production of MDF began in the 1980s, in both North America and Europe. Physical properties Over time, the term "MDF" has become a generic name for any dry-process fibre board. MDF is typically made up of 82% wood fibre, 9% urea-formaldehyde resin glue, 8% water, and 1% paraffin wax. The density is typically between . The range of density and classification as light-, standard-, or high-density board is a misnomer and confusing. The density of the bo ...

Particle Board
Particle board, also known as chipboard or low-density fiberboard, is an engineered wood product manufactured from wood chips and a synthetic resin or other suitable binder, which is pressed and extruded. Particle board is often confused with oriented strand board (OSB) (also known as flakeboard, or waferboard), a different type of fiberboard that uses machined wood flakes and offers more strength. Characteristics Particle board is cheaper, denser and more uniform than conventional wood and plywood and is substituted for them when cost is more important than strength and appearance. Particleboard can be made more appealing by painting or the use of wood veneers on visible surfaces. Though it is denser than conventional wood, it is the lightest and weakest type of fiberboard, except for insulation board. Medium-density fibreboard and hardboard, also called high-density fiberboard, are stronger and denser than particleboard. Different grades of particleboard have different densi ...

Urea-formaldehyde
Urea-formaldehyde (UF), also known as urea-methanal, so named for its common synthesis pathway and overall structure, is a nontransparent thermosetting resin or polymer. It is produced from urea and formaldehyde. These resins are used in adhesives, plywood, particle board, medium-density fibreboard (MDF), and molded objects. UF and relate amino resins are a class of thermosetting resins of which urea-formaldehyde resins make up 80% produced worldwide. Examples of amino resins use include in automobile tires to improve the bonding of rubber to in paper for improving tear strength, in molding electrical devices, jar caps, etc. History UF was first synthesized in 1884 by Dr Hölzer, who was working with Bernhard Tollens, neither of whom realized that the urea and formaldehyde were polymerizing. In the following years a large number of authors worked on the structure of these resins. In 1896, Carl Goldschmidt investigated the reaction further. He also obtained an amorphous, almos ...

Plywood
Plywood is a material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which include medium-density fibreboard (MDF), oriented strand board (OSB) and particle board (chipboard). All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. This alternation of the grain is called ''cross-graining'' and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There is usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardboard
Hardboard, also called high-density fiberboard (HDF), is a type of fiberboard, which is an engineered wood product. It is used in furniture and in the construction industry. Description Hardboard is similar to particle board and medium-density fiberboard, but is denser and much stronger and harder because it is made out of exploded wood fibers that have been highly compressed. Consequently, the density of hardboard is or more and is usually about . It differs from particle board in that the bonding of the wood fibers requires no additional adhesive, the original lignin in the wood fibers sufficing to bond the hardboard together, although resin is often added. Hardboard is produced in either a wet or dry process. The wet process, known as the Mason Method, leaves one smooth side and one textured side, while the dry processed hardboard is smooth on both sides. Masonite is produced using the wet process only. History A product resembling hardboard was first made in England in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donnacona Fiberboard
Chief Donnacona (died 1539 in France) was the chief of the St. Lawrence Iroquois village of Stadacona, located at the present site of Quebec City, Quebec, Canada. French explorer Jacques Cartier, concluding his second voyage to what is now Canada, returned to France with Donnacona. Donnacona was treated well in France but he died there. Later Cartier would make a third voyage to the same area. Cartier's first voyage Jacques Cartier made three voyages to the land now called Canada, in 1536, 1538 and 1549. In late July 1534, in the course of his first voyage, he and his men encountered two hundred people fishing near Gaspé Bay. Cartier's men erected a "thirty foot long" cross which provoked a reaction from the leader of this fishing party. After some presentation of gifts to the people there, he left the area the next day, with two men on board, Domagaya and Taignoagny, from the fishing party. He returned to France with them, concluding his first voyage in September 1534. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homasote
Homasote is a brand name associated with the product generically known as cellulose-based fiber wall board, which is similar in composition to papier-mâché, made from recycled paper that is compressed under high temperature and pressure. Homasote contains no adhesives. It is held together by the surface tension between the paper fibers, a process that is augmented by hydrogen bonding and the presence of a wax binder (2% volume). It is available in multiple thicknesses and comes in sheets . The Homasote Company operates a factory in the West Trenton section of Ewing Township, New Jersey. History The Agasote Millboard Company was founded as a division of the Bermuda Trading Company in 1909 by Eugenius Harvey Outerbridge. Outerbridge brought the process to the United States from England. The first commercial use of the panels were for lining railroad cars. In 1915, the company won a contract to use the panels as automobile tops. From 1915 to 1925, they supplied board for the t ...

Corrugated Fiberboard
Corrugated fiberboard or corrugated cardboard is a type of packaging material consisting of a fluted corrugated sheet and one or two flat linerboards. It is made on "flute lamination machines" or "corrugators" and is used for making corrugated boxes. The corrugated medium sheet and the linerboard(s) are made of kraft containerboard, a paperboard material usually over thick. History Corrugated (also called pleated) paper was patented in England in 1856, and used as a liner for tall hats, but corrugated boxboard was not patented and used as a shipping material until 20 December 1871. The patent was issued to Albert Jones of New York City for single-sided (single-face) corrugated board. Jones used the corrugated board for wrapping bottles and glass lantern chimneys. The first machine for producing large quantities of corrugated board was built in 1874 by G. Smyth, and in the same year Oliver Long improved upon Jones' design by inventing corrugated board with liner sheets on both ...

Beaverboard
Beaverboard (also beaver board) is a fiberboard building material, formed of wood fibre compressed into sheets. It was originally a trademark. It has occasionally been used as a canvas by artists. The painting ''American Gothic'' (1930) by Grant Wood was painted on a beaverboard panel. See also *Paperboard Paperboard is a thick paper-based material. While there is no rigid differentiation between paper and paperboard, paperboard is generally thicker (usually over 0.30 mm, 0.012 in, or 12 Inch#equivalences, points) than paper and has certain ...

Online Newspaper
An online newspaper (or electronic news or electronic news publication) is the online version of a newspaper, either as a stand-alone publication or as the online version of a printed periodical. Going online created more opportunities for newspapers, such as competing with broadcast journalism in presenting breaking news in a more timely manner. The credibility and strong brand recognition of well established newspapers, and the close relationships they have with advertisers, are also seen by many in the newspaper industry as strengthening their chances of survival. The movement away from the printing process can also help decrease costs. Online newspapers, like printed newspapers, have legal restrictions regarding libel, privacy, and copyright, also apply to online publications in most countries as in the UK. Also, the UK Data Protection Act applies to online newspapers and news pages. Up to 2014, the PCC ruled in the UK, but there was no clear distinction between authentic o ...
