Method and apparatus for recycling plastic waste into a thin profile, mechanically reinforced board

摘要: The present invention relates to a method and apparatus for forming an extruded plastic lumbar product from commingled waste feed stock. generally includes extruder portion portion. compound which compresses melts the by sudden transition within constant pitch conveyor. From extruder, melt is introduced into hot formed so as prevent vortex of or mixing different resins. conveyor diminishing along its length short section metering section. then desired profile through cross-head die in series rovings are melt. serve reinforcement well define rate. Because blend dissimilar resins material, there often inconsistencies strength. compensate these provide having strength stiffness characteristics.
