IN-LINE COMPOUNDING AND EXTRUSION SYSTEM |
摘要 |
<p>The present invention is a continuous in-line compounding and extrusion system that does not require pre-dried wood flour or pelletized feed stock of cellulosic/polymer composite materials in order to produce net shapes from cellulosic/polymer composite materials. A preferred embodiment of the present invention utilizes automated loss-in-weight feeders to dispense wood flour and all of the other cellulosic/polymer composite materials into a compounder. The compounder blends the cellulosic/polymer composite materials into a composite melt. The composite melt is continuously devolitalized as it travels through the compounder, a transition chute, and a finish extruder. The composite melt is then forced through a profile die which is fitted to the finish extruder in order to achieve a net shape.</p> |
