摘要： A toner extruder method for the preparation of a toner resin extrudate from a resin is provided. The method includes conveying a base resin to an aperture in a housing of a toner extruder, the housing surrounding a conveyor, providing a lead-in gap at a feed port end of the conveyor, inhibiting adhesion of melted resin to walls of the aperture, adding chemical initiator to a toner extruder, mixing the base resin and the chemical initiator within the extruder to form the mixed resin, and conveying the mixed resin within the extruder to an extruding die. Inhibiting adhesion can include repelling melted base resin into a flow of base resin, inhibiting heat transfer from the extruder to the base resin at the aperture by, for example, spacing at least one of the housing and the conveyor from the resin at the aperture.

摘要： A screw type processing device provides a film-formable thermoplastic composition formed mainly of polysaccharide and protein by continuously compressing substances together with carbon dioxide gas to form fluid in a critical state, processes the fluid and is capable of efficiently manufacturing a practicable polyester foam body. A pressure reduction part with increased space volume between screw vanes is formed continuously with an extruding screw of a material supply part by reducing the diameter of the shaft of the screw, and carbon dioxide gas is led into the pressure reduction part. Also, a compression part formed of a screw having a shaft with increased diameter and narrowed vanes is positioned after the pressure reduction part. The diameter of the shaft is made substantially equal to the inner periphery of a barrel, and an orifice part having an orifice formed on the surface or periphery of the shaft is formed. The maximum flow velocity of orifice passing substances is desirably designed to be 10 to 1500 cm/sec.
