1Proyzvostvo and application of wood slabs .Proyzvodstvo of particle board (chipboard) Under terms of proyzvodstvo and Structure (MAP) divided into piston and плоскопресувани.Буталнопресовите plates are solid or hollow and used for special tseli.Plosko pressing plates which are single-layer, three-layer and multilayer are pryzvezhdat mass and structure in wood promishlenost.Proyzvodstvo of fibreboard (SAPs) .Po currently saint consulting group found proyzvodstvoto of SAPs on various methods, wet, dry, semi-dry, wet -dry, with different density saint consulting group -from 80 to 1400kg / m 3, with different properties hydro, bio and ogneoostoychivi with different prednazanachenie- construction and lining. Proyzvodstvo of high and medium dense fibreboard. Proyzvodstvoto of MDF plates date back 60 years, initially in the US and then is transported In Europe. Initially, it was based on the wet method in which the time of molding increases with an increase in the thickness of the plates. The density of these plates is close to the density chipboard (600 do900kg / m 3), and the thickness varies from 3.2 to 60mm. The technology and design of the equipment used are similar to those for proyzvodstvo saint consulting group of PDC, the difference being in the extraction of the particles and the fibers. Compared to fiber particles have a small bulk density, which leads to congestion pneumatic-with-my accumulation in drying and gluing equipment, as well as fires and dust eksplozii.Vsichki saint consulting group production processes are fully mechanized and automated. In contemporary factories are introduced automatic control, process control and automatic quality control using mikroprotsesurni systems. To ensure the profitability saint consulting group of the plants is essential proyzvodstvena their average power that Europe saint consulting group is 105 thousand m3 for the US - 130 thousand m3. Use of wood slabs. The main application is in the furniture and construction industries. Moreover, it is applied in shipbuilding, production of vehicles saint consulting group and drugi.Po their qualities they are considered unique composite material that allows designers of furniture successfully saint consulting group use priemushtestvota as good workability and high quality saint consulting group finishing. Guidelines for development of the wooden plates. Not yet mastered all the raw resources. In pryzvodstvenite processes saint consulting group for wood panels into account the following material losses: crushing and feathering of woody raw material drying, sorting and transportation of wood particles and fibers, wood pressing plate format saint consulting group deburring and grinding plates. Progressive trend manifested in recent years is the implementation of centralized cutting using automated lines and process optimization, rocker by microcomputers.
5Darvesna material, saint consulting group and ligno-industrial waste. Preparing for crushing and razvlaknyavane- methods and equipment. saint consulting group Wood is the basic building materyali of wood slabs and determinant of the defining quality in production. The type of wood raw material influence on the one hand on the technological processes in various stages of preparation of wood panels and more on the cost of production. Nai important indicator of wood as a raw material for PDP is its density. Conducted by global research uustanoveno Research Fund is that at the same density of the output saint consulting group timber higher strength indicators have plates made of wooden species with low density. Wood raw material for PDP can ubosobi in the following groups: round and split wood, industrial waste and agricultural lignocellulosic lesosecheni and dry. Waste. Round and split wood is obtained by logging in amount 40% of juvenile material in the form of firewood, twigs, leaves, saint consulting group bark, stumps and more. Nai suitable saint consulting group however soft deciduous and coniferous wood that produces high-quality particles and fibers with a number of technological advantages in processing. Technological waste are produced in the machining of wood, which are concentrated as waste in woodcut, fornirnoto, parquet and furniture. In fact, they account for one third of moisture in wood raw material PDP. Agricultural lignocellulosic wastes one-perennial crops of interest to the PDP application in the furniture industry as a raw material for their middle layers. In the manufacture of building panels is possible to use almost all of lignocellulosic materials such as materyali with low density is applied in the preparation of izulatsionni products. It should saint consulting group be noted that certain lignocellulosic raw materials are superior to wood and they can be manufacturable wood panels with high phi
