Kumvetsetsa Twin-Screw Extruders
Kutanthauzira Twin-Screw Extruders
Zotulutsa ziwiri-screwndi makina apamwamba omwe amagwiritsidwa ntchito polima polima kuti asungunuke, kusakaniza, ndi kupanga zinthu. Mosiyana ndi zotulutsa zokhala ndi sikelo imodzi, zimakhala ndi zomangira ziwiri zomwe zimazungulira mkati mwa mbiya, zomwe zimapatsa mphamvu zowongolera pakuyenda ndi kusakanikirana kwa zinthu. Mapangidwe awo amalola kusintha koyenera kumeta ubweya, kutentha, ndi kupanikizika, kuwapanga kukhala abwino kwa ntchito zovuta.
Gome lotsatirali likuwonetsa zinthu zazikulu zomwe zimatanthauzira ma twin-screw extruders:
| Mbali | Kufotokozera |
|---|---|
| Geometry | Ili ndi zomangira ziwiri zokhala ndi intermeshing geometry, mosiyana ndi makina a sikelo imodzi. |
| Njira | Amagwiritsa ntchito njira yapadera yosungunula, kusakaniza, ndi kupopera zinthu. |
| Mapulogalamu | Oyenera njira zotsogola monga kuphatikizika kwamagawo angapo komanso kutulutsa kokhazikika. |
| Kuvuta | Pamafunika mapangidwe apadera ndi mayina chifukwa cha kapangidwe kake kovuta. |
| Kuyerekezera | Imapambana ma extruder a single-screw pakusakaniza, kuwongolera kutentha, ndi kusinthasintha kwazinthu. |
Izi zimapangitsa kuti ma twin-screw extruder akhale ofunikira m'mafakitale omwe amafunikira kulondola kwambiri komanso kuchita bwino.
Kufunika Pakukonza ndi Kuphatikizira Polima
Twin-screw extruder amagwira ntchito yofunika kwambiripolima processingpothandizira kuphatikizika koyenera, kuphatikiza, ndi kuwononga. Kukhoza kwawo kugwiritsira ntchito zipangizo zosiyanasiyana, kuphatikizapo thermoplastics, elastomers, ndi fillers, zimawapangitsa kukhala zida zosunthika popanga.
Kafukufuku akuwonetsa kuti ma extruder amapasa amatha kuwirikiza kawiri muntchito zothamanga kwambiri popanda kutentha kwambiri. Kuchita bwino kumeneku kumachokera ku mapangidwe awo apamwamba kwambiri, omwe amawongolera kuyenda ndi kusakanikirana kwazinthu. Kuphatikiza apo, kuwongolera kwawo kutentha kwapamwamba kumawonetsetsa kuti zinthu zili bwino, ngakhale pakugwiritsa ntchito movutikira.
Gome ili m'munsili likufanizira kuthekera kwawo ndi ma extruder a single-screw:
