Multilaminar veneer

Last updated

Multilaminar wood veneer uses plantation wood to reproduce decorative effects that are typical of quality wood species (often protected and rare). This aids the preservation of biodiversity and complies with the principles of sustainable forest management.

Wood fibrous material from trees or other plants

Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic material, a natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber.

Biodiversity Variety and variability of life forms

Biodiversity refers to the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth, and is richest in the tropics. These tropical forest ecosystems cover less than 10 percent of earth's surface, and contain about 90 percent of the world's species. Marine biodiversity is usually highest along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future.

In this veneering process, large sheets of veneer are produced on a machine similar to a lathe. These are dyed, spread with suitable adhesives, and then compressed and bonded into thick (typically 70 cm) logs, which are then sliced to create the end product. If the sheets are compressed between platens with an undulating surface, the slice will cross several layers to produce a patterned effect. Many different designs can be obtained by varying the platens, the dyes and the stacking order. [1]

Wood veneer

In woodworking, veneer refers to thin slices of wood and sometimes bark, usually thinner than 3 mm, that typically are glued onto core panels to produce flat panels such as doors, tops and panels for cabinets, parquet floors and parts of furniture. They are also used in marquetry. Plywood consists of three or more layers of veneer. Normally, each is glued with its grain at right angles to adjacent layers for strength. Veneer beading is a thin layer of decorative edging placed around objects, such as jewelry boxes. Veneer is also used to replace decorative papers in Wood Veneer HPL. Veneer is also a type of manufactured board.

Lathe machine tool which rotates the workpiece on its axis

A lathe is a machine that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, and turning, with tools that are applied to the workpiece to create an object with symmetry about that axis.

Dye colored substance that has an affinity to the substrate to which it is being applied

A dye is a colored substance that chemically bond to the substrate to which it is being applied, this distinguishes dyes from pigments which do not chemically bind to the material they colour. The dye is generally applied in an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber.

Although the product may be considered sustainable, multilaminar veneer does have a relatively high carbon footprint due to the numerous dyeing, laminating, pressing, and slicing operations.[ citation needed ]

Carbon footprint total set of greenhouse gas emissions caused by an individual, event, organisation, or product, expressed as carbon dioxide equivalent

A carbon footprint is historically defined as the total emissions caused by an individual, event, organization, or product, expressed as carbon dioxide equivalent. Greenhouse gases (GHGs), including carbon dioxide, can be emitted through land clearance and the production and consumption of food, fuels, manufactured goods, materials, wood, roads, buildings, transportation and other services.

Plywood manufactured wood panel made from thin sheets of wood veneer

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 includes medium-density fibreboard (MDF) and particle board (chipboard).

Marquetry

Marquetry is the art and craft of applying pieces of veneer to a structure to form decorative patterns, designs or pictures. The technique may be applied to case furniture or even seat furniture, to decorative small objects with smooth, veneerable surfaces or to freestanding pictorial panels appreciated in their own right.

Engineered wood range of derivative wood products

Engineered wood, also called 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 materials. These products are engineered to precise design specifications which are tested to meet national or international standards. Engineered wood products are used in a variety of applications, from home construction to commercial buildings to industrial products. The products can be used for joists and beams that replace steel in many building projects.

Medium-density fibreboard engineered wood product

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 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 much denser than particle board.

Formica (plastic) brand of composite materials

Formica laminate is a laminated composite material invented at the Westinghouse Electric Corporation in the United States in 1912. Originally used to replace mica in electrical applications, it has since been manufactured for a variety of applications. Today, the product is produced by New Zealand-based Formica Group, and has been since 2007. The word Formica refers to the company's classic product: a heat-resistant, wipe-clean laminate of paper or textile with melamine resin.

Lamination technique of fusing layers of material

Lamination is the technique/process of manufacturing a material in multiple layers, so that the composite material achieves improved strength, stability, sound insulation, appearance or other properties from the use of differing materials. A laminate is a permanently assembled object by heat, pressure, welding, or adhesives.

Particle board pressed wood board

Particle board – also known as particleboard, low-density fibreboard (LDF), and chipboard – is an engineered wood product manufactured from wood chips, sawmill shavings, or even sawdust, and a synthetic resin or other suitable binder, which is pressed and extruded. Oriented strand board, also known as flakeboard, waferboard, or chipboard is similar, but uses machined wood flakes offering more strength. All of these are composite materials that belong to the spectrum of fiberboard products.

Hardboard type of fiberboard

Hardboard, also called high-density fiberboard (HDF), is a type of fiberboard, which is an engineered wood product.

Compression molding

Compression Moulding is a method of moulding in which the moulding material, generally preheated, is first placed in an open, heated mould cavity. The mould is closed with a top force or plug member, pressure is applied to force the material into contact with all mould areas, while heat and pressure are maintained until the moulding material has cured. The process employs thermosetting resins in a partially cured stage, either in the form of granules, putty-like masses, or preforms.

Wood finishing

Wood finishing refers to the process of refining or protecting a wooden surface, especially in the production of furniture where typically it represents between 5 and 30% of manufacturing costs.

A pellet mill, also known as a pellet press, is a type of mill or machine press used to create pellets from powdered material. Pellet mills are unlike grinding mills, in that they combine small materials into a larger, homogeneous mass, rather than break large materials into smaller pieces.

Fiberboard type of engineered wood product that is made out of wood fibers

Fiberboard is a type of engineered wood product that is made out of wood fibers. Types of fiberboard include particle board or low-density fiberboard (LDF), medium-density fiberboard (MDF), and hardboard.

Columbia Forest Products is the largest manufacturer of hardwood veneer and hardwood plywood in the United States. Founded in 1957, it is headquartered in Greensboro, North Carolina. It specializes in decorative, interior veneers and plywood panels that are used in high-end cabinetry, fine furniture, architectural millwork and commercial fixtures. The company distributes its products primarily through a network of wholesale distributors, mass merchandisers and OEMs. Since 1976, the company has been completely employee-owned and currently has 10 manufacturing facilities throughout the U.S. and Canada. At the end of 2006, Columbia converted all of its standard hardwood plywood production to produce formaldehyde-free panels called PureBond. In 2007 Columbia added PureBond formaldehyde-free particleboard to its product range.

Wood flooring

Wood flooring is any product manufactured from timber that is designed for use as flooring, either structural or aesthetic. Wood is a common choice as a flooring material and can come in various styles, colors, cuts, and species. Bamboo flooring is often considered a form of wood flooring, although it is made from a grass (bamboo) rather than a timber.

Anigre is an African hardwood commonly used for plywood, interior furniture, cabinetry, and high-end millwork applications. It is frequently sliced and sold as veneer, although it is available in board form as well. In board form it is used for boat building, general carpentry, and other light construction uses.

Tego film is an adhesive sheet, used in the manufacture of waterproof plywood. It is applied dry and cured by heat, which allows for high-quality laminates that are free from internal voids and warping. Tego film plywoods were used in aircraft manufacture in Germany during World War II, and the loss of the plant during a 1943 bombing raid was a serious blow to several aircraft projects.

Self-leveling concrete

Self-leveling concrete is polymer-modified cement that has high flow characteristics and, in contrast to traditional concrete, does not require the addition of excessive amounts of water for placement. Self-leveling concrete is typically used to create a flat and smooth surface with a compressive strength similar to or higher than that of traditional concrete prior to installing interior floor coverings. Self-leveling concrete has increased in popularity as the degree of flatness and smoothness required for floor covering products has increased, with vinyl goods becoming thinner and floor tiles becoming larger, for example.

Molded plywood

Molded plywood is the term for two- or three-dimensionally shaped products from multiple veneer layers that are glued together through heat and pressure in a pressing tool. The veneer layers are arranged crosswise at an angle of 90 degrees. Molded wood is used for flat furniture components such as seats, backrests and seat shells. When the veneer layers are arranged in the same direction, it is called laminated wood. It is used for armrests and chair frames. After pressing, the blanks are processed mechanically. A particular feature is the ability to produce different variations of shapes from the blanks. Due to its immense strength and low weight, molded wood is particularly suitable for interior decoration, seating furniture, bed slats, skateboards and vehicle construction.
