Siv tau Degassing thiab Venting:Lub intermeshing screws thiab kaw lub thoob tsim pab txhawb kev tshem tawm cov pa roj carbon monoxide thiab noo noo los ntawm polymer yaj, ua cov khoom zoo nrog cov voids tsawg thiab npuas.
Versatility rau cov txheej txheem nyuaj:Lawv zoo haum rau cov txheej txheem nyuaj xws li reactive extrusion thiab polymer blending.
Kev txwv ntawm Twin Screw Extruders:
Tus nqi siab dua: Twin ntsia hlau extruderfeem ntau kim dua ib qho ntsia hlau extruders.
Kev ua haujlwm nyuaj:Lawv cov qauv tsim tshwj xeeb yuav xav tau kev tshaj lij tshwj xeeb los ua haujlwm.
Kev siv zog ntau dua:Lawv txoj haujlwm yuav siv zog ntau dua piv rau ib qho ntsia hlau extruders.
