Title:
SIMULATION APPARATUS FOR SCREW EXTRUDER VOLATILIZATION AND SIMULATION PROGRAM FOR SCREW EXTRUDER VOLATILIZATION
Document Type and Number:
WIPO Patent Application WO/2007/119506
Kind Code:
A1
Abstract:
A simulation apparatus, and program, for screw extruder volatilization, being
capable of practical simulation of the volatilization process of screw extruder.
There is provided an extruder simulation system capable of simulation of volatilization
condition through computing of intra-extruder resin temperature, pressure,
stay time, filling ratio, torque, power, solid-phase occupancy and volatile
contents concentration as a distribution in the direction of extruder axle from
extruder apparatus structure, operating conditions and resin properties,
which extruder simulation system includes means for arithmetical operation
for the process of gradual decline of volatile contents concentration of the
resin by volatilization by vent cylinder.
