Plywood is a composite product made from sheets of veneer are glued together with an array of intersecting perpendicular.<\/span> Plywood included in one class of structural panel, in which direction is the use of plywood for structural panels.<\/span> Plywood or so-called plywood (plywood to plywood with 3 layers, and multiplex to plywood with 5 layers or more), according to the definition of the experts are as follows:<\/span>
\n \uf0a7 Plywood is a product obtained by arranging intersect perpendicularly intersect veneer sheets bonded with an adhesive, at least 3 (three) layers (ISO, 1992).<\/span>
\n \uf0a7 Tsoumis (1991) suggested that, plywood is a product panels made with glue or glue a sheet of veneer sheets vini on sawn timber, where the sawn timber as part of the core \/ core (better known as wood core plywood).<\/span> The fiber direction on the sheet of veneer to face and coreadalah perpendicular to each other, while between the sheets of veneer to face each other in parallel.<\/span>
\n \uf0a7 Youngquist (1999) suggested that the plywood is a flat panel composed of sheets of veneer to be held together by a binder (adhesive) under conditions of compression.<\/span>
\n \uf0a7 Haygreen and Bowyer (1993) suggested that the plywood is a product-veneer wood veneer panels are bonded together so that the fiber direction perpendicular vinirnya number and the other sejejar the long axis of the panels.<\/span><\/p>\n

Sections plywood<\/strong><\/span>
\n In general, materials plywood \/ plywood adalahsebagai following:<\/span>
\n<\/a><\/p>\n

a) Face Veneer<\/strong><\/span>
\n \uf0b7 a minimum diameter of 45 cm<\/span>
\n \uf0b7 Logs should be straight, spherical and cylindrical<\/span>
\n \uf0b7 Wood should be fresh<\/span>
\n There is no defect \uf0b7 wood<\/span>
\n \uf0b7 There are no knots unhealthy<\/span><\/p>\n

b) Core Veneer<\/strong><\/span>
\n \uf0b7 a minimum diameter of 45 cm<\/span>
\n \uf0b7 Log of at least 85% cylindrical<\/span>
\n \uf0b7 Admission to the part that is not bent origin parabola<\/span>
\n \uf0b7 Wood should be fresh<\/span>
\n \uf0b7 Allow any defects such as knots healthy wood, weathered liver (diameter less than 1\/3 the diameter bontos)<\/span><\/p>\n

c) a back layer<\/strong><\/span>
\n<\/strong> \uf0b7 Quality of veneer for the back layer is not as good of a designated face veneer layer.<\/span> Examples of wood that can be used as raw material for plywood, among others, meranti, camphor, mersawa, mengkulang, gerunggang, mahogany, agathis, tamarind, sengon, Mindi and forth.<\/span> .Diameter Log used suggested above 30 cm, but this time the machines are more modern can process logs with a smaller diameter.<\/span><\/p>\n

For purposes as a coating (fancy-plywood) types of wood that can be used a little differently, because it prioritizes decorative nature.<\/span> For this purpose, the type of wood that can be used is of a type of wood is expensive and has a nice grain direction (decorative).<\/span> For example wood, among others: teak, rosewood, ebony, varnish, nail, nyatoh, and so on.<\/span> In the process, various materials can be used as a coating for example PVC, metal, Formica or paper.<\/span><\/p>\n

d) Benefits \/ Uses Plywood<\/strong><\/span>
\n a) Construction of buildings<\/span>
\n \uf0b7 Paneling: room divider, door, window<\/span>
\n \uf0b7 Coating materials<\/span>
\n \uf0b7 Floor<\/span>
\n \uf0b7 Sidding: wall<\/span>
\n \uf0b7 Plyform<\/span>
\n b) Construction means of transportation<\/span>
\n \uf0b7 Aircraft: coating the inner wall<\/span>
\n \uf0b7 Train: roofs, floors, walls<\/span>
\n \uf0b7 Truck and trailer: body<\/span><\/p>\n

e) Classification of plywood<\/strong><\/span>
\n Based on its use, plywood grouped into two: the interior and exterior plywood.<\/span> Youngquis (1999) grouping of plywood into two parts:<\/span>
\n \uf0b7 construction and industrial plywood<\/span>
\n \uf0b7 hardwood plywood and decorative.<\/span><\/p>\n

Based on the type of adhesive used, the grouping of plywood can be divided into two (Iswanto, 2008):<\/span>
\n \uf0b7 Plywood plywood interior is its use indoors or in other words, is not directly exposed to outdoor environmental conditions, the adhesive used is an interior adhesive such as UF, MF and MUF.<\/span>
\n \uf0b7 plywood exterior plywood is its use in outdoor directly exposed to outdoor conditions, the adhesive used is an adhesive exteriors such as PF.<\/span>
\n Based finir face, plywood grouped into:<\/span>
\n \uf0b7 Ordinary plywood is plywood which faces finir generated from rotary cutting process.<\/span>
\n \uf0b7 Fancy plywood is plywood where finir face made of beautiful wood and produced from the process of cutting or half slice rotary cutting.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
