Fiber board
By lignocellulose fibers mixed molding and take advantage of its inherent adhesive made of man-made board performance.Can be applied in the process of manufacturing adhesive and (or) additives.
Fiber board is density board, with wood fiber or other plant fiber as raw materials, applying urea-formaldehyde resin or other suitable adhesive made of man-made board.Can be applied in the process of manufacturing adhesive and (or) additives.Fiber board has the material evenly, the advantages of vertical and horizontal intensity difference is small, not easy craze, wide range of USES.Make 1 cubic meters of fiber board takes about 2.5 ~ 3 cubic meters of wood, but instead of 3 m3 lumber or 5 cubic meters of logs.Development of fiberboard production is an effective way of comprehensive utilization of wood resources.
Fiberboard faults is on the back of the net, surface area, causing both sides due to expansion force difference after moisture absorption plate buckling deformation;Rigid plate on the surface of hard, nailing difficulties, poor water resistance.Although dry-process fiberboard avoids some shortcomings, but the cost is higher.
The fiberboard production started in the 1970 s, the development of our country in the 80 s, take off in the 90 s, since entering the 21st century, fiberboard production increase by a wide margin, and 2005 in the first time break 20 million m3 to 49.54 million cubic meters in 2011.From the perspective of the production of various provinces and cities, fiberboard production in henan province of 6.98 million cubic meters in 2011, up 44.87% from 2010, accounting for 14.09% of the total national output.Followed by the guangxi, jiangsu and shandong, respectively accounted for 12.84%, 9.76% and 8.56% of total output.July 1, 2012 Chinese fiberboard production reached 29805100.39 square meters, more than the same period in 2011 increased by 11.3%.
