The twin-screw extruder imagawidwa kukhala mtundu wokondana ndi mtundu wosagwira ntchito molingana ndi malo achibale a zomangira ziwirizo.Mtundu wa mauna umagawidwa mumtundu wa ma mesh pang'ono ndi mtundu wa mauna athunthu malinga ndi kuchuluka kwa ma meshing.The twin-screw extruder imagawidwa m'mitundu iwiri: wononga kozungulira komweko ndi zomangira zozungulira motsatana ndi kozungulira.

Pansipa, Xiaobian akupatsirani chidule chachidule cha zovuta zamaluso zamapasa-screw extruders.

1. Wonjezerani liwiro la screw, lomwe limathandizira kupanga kuwira, kukula ndi kuphulika, komwe kumapindulitsa kuchepetsa kutalika kwa zinthu zomwe zili mu screw groove, kupititsa patsogolo kukonzanso kwa zinthu zosinthira, ndikuwongolera magwiridwe antchito a devolatilization. ;komabe, kuthamanga kwambiri kumapangitsa zinthuzo Nthawi yokhala mu gawo la devolatilization imachepetsedwa kwambiri, ndipo mphamvu ya devolatilization imachepa.

2. Kuthamanga kwakukulu kwa wononga, kuchuluka kwa chakudya ndi kutentha kwa mbiya ndizo zikuluzikulu zomwe zimakhudza ndondomeko ya devolatilization mu mapasa-screw extruder.Zinthu izi zimatha kukhudza kutentha kwa zinthu, kudzaza kwa groove, nthawi yokhalamo komanso kutalika kwanthawi zonse, zomwe zimakhudza kuwononga mphamvu m'njira zambiri.Pogwiritsa ntchito njira inayake, pali malo abwino kwambiri ogwirira ntchito, ndipo pakagwira ntchito mokhazikika, mphamvu yapamwamba kwambiri ya devolatilization ingapezeke.

3, kuchepetsa koyenera kwa chakudya kumatha kuchepetsa kudzaza kwa gawo la utsi, kuti mphamvu ya devolatilization ipite patsogolo;koma kuchuluka kwa chakudya chochepa kwambiri sikungochepetsa kuchuluka kwa extrusion ndi kusinthasintha, komanso chifukwa kudzaza kutsika kwambiri, sikukwanira kupanga kusungunuka Madziwo amachepetsa mphamvu ya thovu ndi devolatilization, kotero kuti chakudya chiyenera kukhala chochepa.

4. Kuonjezera nthawi yokhala ndi zinthu zomwe zili mu gawo la devolatilization ndikuwonjezera kutalika kwa gawo la devolatilization kungathandize kuti ntchito ya devolatilization ikhale yabwino.Pachifukwa ichi, zimaganiziridwa kuti zikuwonjezera kutalika kwa gawo lotulutsa mpweya ndikutengera kutulutsa kwamitundu yambiri pamapangidwe a screw.
