TH29253B - Methods for the continuous production of lignin and cellulose plank. - Google Patents

Abstract

Methodology for the continuous production of fiber-reinforced boards Contains lignin and cellulose, in which the material is Broken down And / or as these fibers are dried, glued and formed into sheets. And pressed into a finished board, which steam will enter the plate In accordance with this invention, a limited amount of steam is introduced into the The first stage of spraying This amount is adjusted so that enough steam penetrates the plate to heat and bake the plate's surface layer. Therefore, it will be A board with a texture layer With a higher density than the middle layer so that the compression is made to Subsequently, a larger thickness will be prepared which allows Let the layer in the middle expand while the layer density The surface will be preserved

Claims (2)

1. Methodology of the continuous production of plank of fibrous material. Lignin and cellulose compounds in which the material is broken down into small / or fibers that are dried, glued and formed into sheets, which are then extruded into a prefabricated sheet through which water vapor is introduced into the plate. In the first steam spraying process a limited amount of steam Will be brought into which will be received Adjustment so that the steam will penetrate, the heat and baking will occur only on the surface layer of the plate. 2. The methodology is consistent with claim 1, which will receive
