Bedrooms pattern of stress

Single-screw extrusion process, due to the effect of a single screw extruder transported mainly by friction, so that the powder material feeding difficulties; outdoor deck flooring and a single-screw extruder exhaust less effective the longer residence time in the barrel. Therefore, in the extrusion process, a larger amount of wood flour, the extrudate darker, smell of burning wood flour; and a melt strength rapidly decreases with increasing amount of wood flour, wood flour when the amount to 150 parts after difficult to make out. Lower relative to HDPE, LDPE melt viscosity, the processing flow better. Therefore to LDPE as the base resin powder, 100 parts of wood flour and add small amounts of other additives, the extrusion molding in a single screw extruder and cut into pellets as a master batch; [url=http://plasticwoodfloor.com/news/4.html]deck flooring material[/url] HDPE pellets and then simply mixed in a single screw extruder plasticized melt extrusion, the extrusion process, high melt strength, can be realized continuously extruded.
