Synthetic wood meal, method and apparatus for manufacturing the same; synthetic wood boards including the synthetic wood meal, method and apparatus of extrusion molding therefor

摘要: A synthetic wood meal in which a thermoplastic resin material of 25 to 80 wt% is mixed with cellulose crushed 20 75 that lies the moisture content within 15 and mean particle diameter mesh or less, kneaded so as be set gel, cooled pulverized regulated size 10 mm less. Then, at rate material, by heating squeezed screw screws an extruding die 78 extruder. When 79 passes through inner wall surface 78, lines fluororesin sheet 24 thereon, included smoothly extruded without being subjected large resisting force, molded article 29 for product having uniform high density predetermined thickness, while applying force against squeezing given from extruder using braking means, thus molding board more higher density.
