Natural Fibre Board
''Natural Fibre Board (NFB)'', or otherwise natural fibreboard or natural fiberboard, is a registered European trademark representing wood fibre boards produced without the use of binding agents, for instance, formaldehyde-based resins or other synthetic resins. It is a European wood-based panel, which belongs to the fibreboards; from the past, it is typically called ''hardboard''. Technically this is a wet-process fibreboard glued only with the natural lignin of the wood material itself. The trademark is licensed to the European Panel Federation (EPF), an organization that represents all European manufacturers of hardboard and softboard using the wet-process system. These manufacturers adhere to stringent product characteristics and production process criteria. Manufacturing process NFB hardboard and softboard products are manufactured by a specialized industry using exclusively pure wood fibres. The production process involves a thermo-mechanical treatment that re-polymerizes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardboard
Hardboard, also called high-density fiberboard (HDF), is a type of fiberboard, which is a ''pressed wood'' or ''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 density, denser, stronger and harder because it is made out of exploded wood fibers that have been highly compressed. The density of hardboard is higher than , usually about . It differs from particle board and medium-density fiberboard 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 as a wire mesh is used to allow moisture to escape. Dry processed hardboard is smooth on both sides. Masonite is produced using the wet p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lignin
Lignin is a class of complex organic polymers that form key structural materials in the support tissues of most plants. Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity and do not rot easily. Chemically, lignins are polymers made by cross-linking phenolic precursors. History Lignin was first mentioned in 1813 by the Swiss botanist A. P. de Candolle, who described it as a fibrous, tasteless material, insoluble in water and alcohol but soluble in weak alkaline solutions, and which can be precipitated from solution using acid. He named the substance "lignine", which is derived from the Latin word '' lignum'', meaning wood. It is one of the most abundant organic polymers on Earth, exceeded only by cellulose and chitin. Lignin constitutes 30% of terrestrial non-fossil organic carbon on Earth, and 20 to 35% of the dry mass of wood. Lignin is present in red algae, which suggest that the common ancestor ...

Medium-density Fibreboard
Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibre, 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 fibre 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. Over time, the term "MDF" has become a generic name for any dry-process fibreboard. Physical properties 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 t ...

Solid Wood
Solid wood is a term most commonly used to distinguish between ordinary lumber and engineered wood, but it also refers to structures that do not have hollow spaces. Engineered wood products are manufactured by binding together wood strands, fibers, or veneers with adhesives to form a composite material. Engineered wood includes plywood, oriented strand board (OSB) and fiberboard. The fact that a product is made from solid wood is often touted in advertisements. However, using solid wood has advantages and disadvantages. Comparison with engineered wood Perhaps the greatest advantage of solid wood is that the wood is the same all the way through, so repairs are relatively easy. Repairs to veneer are much more difficult and sometimes impossible. Solid wood furniture is strong enough to easily satisfy all furniture applications, and it can last for centuries. Society is still questioning whether furniture made of plywood (often made from pine) can do the same. Plywood and other eng ...

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, 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.
