Thanks to this design, the devolatilizing performance is approximately 50 times greater than that of a conventional single screw extruder--and this at a vacuum of only 25 to 40 mbar.
However, he did not give a quantitative comparison of the devolatilizing performances between them.
The devolatilizing behavior of volatiles from wood-flour during drying was simulated using a TGA.
cal] can be regarded as a theoretical measure of the devolatilizing performance of a vent section or a vented screw extruder.
The machine was able to extract the oil because of its extremely high devolatilizing capacity (approximately 25 times greater surface-area exchange rate under vacuum than an equivalent twin-screw extruder), Gneuss reports.
In addition, increased free volume enables higher polymer-surface renewal, resulting in improved devolatilizing capability.
Devolatilizing performance is said to be 50 times greater than that of a conventional single-screw extruder--at a vacuum of only 25 to 40 mbar.
JSW offers twin-screw extruders, ranging in size from 20 to 443 mm, for color concentrates, wood flour, nanocomposites, devolatilizing, dewatering, and other applications.
The clearance between the end of the rotor and the faceplate restricted the material flow and allowed for devolatilizing to take place.
Specialty designs for melt-fed compounding, devolatilizing, and reactive extrusion.
Extruders ranging in size from 20 to 443 mm are available for color concentrates, wood flour, nanocomposites, devolatilizing, de-watering, and other applications.
By comparing the manufacturing costs and economics of the two rubber finishing methods, the water slurry process and the direct devolatilizing extruder process, the economic advantage of eliminating the steam stripping step can be determined.
