Kodi mapasa a screw extruder amagwira ntchito bwanji?

Monga kutsogolera mapasa wononga extruder wopanga,Qiangshengplasamazindikira kufunikira kwa kumvetsetsa magwiridwe antchito a mapasa opangira ma screw extruder kuti ayamikire kusinthasintha kwawo komanso magwiridwe antchito osiyanasiyana polima polima. Chitsogozo chatsatanetsatanechi chimayang'ana pamakina a ma twin screw extruder, kukupatsani mphamvu kuti mumvetsetse mfundo zomwe zimagwira ntchito ndikuzindikira zabwino zawo zapadera.

Chofunika cha Twin Screw Extruders

Ma Twin screw extruder adasintha makampani opanga ma polima poyambitsa njira yatsopano yogwirira, kusakaniza, ndi kusungunuka. Mosiyana ndi zomangira zing'onozing'ono, ma screw extruder amagwiritsira ntchito zomangira ziwiri zozungulira zomwe zimazungulira mbali imodzi (zozungulira) kapena zosiyana (zozungulira). Kukonzekera kwapaderaku kumapereka maubwino angapo, kupangitsa ma screw extruder kukhala chisankho chomwe amakonda pamapulogalamu omwe akufuna.

Kutsegula Mfundo Zogwirira Ntchito

Kutumiza Kwabwino Kwambiri:Kuphatikizika kwa zomangira zamapasa kumapanga njira yabwino yosamutsira, kuwonetsetsa kuti zinthu ziziyenda mokhazikika komanso zopanda kutulutsa. Kuthekera kotumizirana zinthu kumeneku n'kofunika kwambiri pa ntchito zomwe zimafuna mtundu wa chinthu chimodzi komanso kuwongolera mosasinthasintha.

Kusakaniza Moyenera ndi Homogenization:Ma geometry otsogola a zomangira amapasa amapanga mphamvu zometa ubweya wambiri, zomwe zimalimbikitsa kusakanikirana bwino komanso kusakanikirana kwa polima kusungunuka. Kuthekera kosakanikirana kotereku ndikofunikira pakuphatikizira zowonjezera, zodzaza, ndi ma pigment mu ma polima matrix, kukwaniritsa kubalalitsidwa kofanana ndi katundu wabwino kwambiri wazogulitsa.

Kusamutsa Kutentha Kwambiri ndi Kusungunula Plasticization:Zomangira za intermeshing ndi mbiya yotsekeka imapereka malo akulu otenthetsera kutentha, kupangitsa kuti polima asungunuke bwino komanso kuyika pulasitiki. Izi imayenera kutentha kutengerapo mphamvu n'kofunika kwambiri pokonza mkulu-makamaka mamasukidwe ma polima ndi kukwaniritsa yunifolomu kusungunula katundu.

Degassing ndi mpweya:Zomangira za intermeshing ndi kapangidwe ka mbiya yotsekeredwa zimathandizira kuchotsedwa kwa mpweya wosakhazikika komanso chinyezi kuchokera ku polima kusungunuka. Kuchita bwino kwa degassing kumeneku ndikofunikira pakupanga zinthu zapamwamba kwambiri zokhala ndi ma voids ochepa komanso thovu.

Ntchito za Twin Screw Extruders

Ma Twin screw extruder apeza kutchuka mumitundu yambiri yama polima polima chifukwa cha kusinthasintha kwawo komanso magwiridwe antchito apamwamba. Ntchito zodziwika bwino ndi izi:

Plasticization ndi kuphatikiza:Ma Twin screw extruder amachita bwino kwambiri popanga pulasitiki ndikuphatikiza ma polima osiyanasiyana, kuphatikiza ma thermoplastics, thermosets, ndi elastomers. Amagwiritsidwa ntchito kwambiri popanga masterbatches, color concentrates, ndi zodzaza zopanga.

Kusakaniza kwa Polima ndi Alloying:Kuthekera kosakanikirana kwa mapasa opangira ma screw extruder kumawapangitsa kukhala abwino kusakaniza ndi kuphatikizira ma polima osiyanasiyana kuti akwaniritse zomwe mukufuna komanso mawonekedwe. Kutha kuphatikiza uku ndikofunikira pakupanga zosakanikirana za polima ndi magwiridwe antchito.

Reactive Extrusion:Ma Twin screw extruder ndi oyenererana bwino ndi njira zosinthira zotulutsa, monga polymerization, kulumikiza, ndi kuwononga, chifukwa chakusakanikirana kwawo bwino komanso kusamutsa kutentha.

Kalozera wa Mawu:

Twin Screw Extruder:Mtundu wa extruder yomwe imagwiritsa ntchito zomangira ziwiri zolumikizirana kuti zipereke, kusakaniza, ndi kusungunula ma polima.

Co-rotating Twin Screw Extruder:Zomangira ziwiri zomangira pomwe zomangira zonse zimazungulira mbali imodzi.

Counter-rotating Twin Screw Extruder:Zomangira ziwiri zomangira pomwe zomangira zimazungulira molunjika.

Kutumiza Kwabwino Kwambiri:Njira yotumizira zinthu zomwe zimatsimikizira kuyenda kosasinthasintha komanso kopanda kugunda.

Zida za Shear:Mphamvu zomwe zimayambitsa mapindikidwe ndi kutuluka kwa zinthu.

Homogenization:Njira yopangira chisakanizo chofanana cha zigawo zosiyanasiyana.

Sungunulani Plasticization:Njira yosinthira polima kuchokera ku cholimba kupita ku chosungunuka.

Degassing:Kuchotsa mpweya wosakhazikika muzinthu.

Polowera mpweya:Kuchotsedwa kwa mpweya kapena mpweya kuchokera kumalo otsekedwa.

Mapeto

Mitundu iwiri ya screw extrudersasintha ma polima popereka njira yosunthika komanso yothandiza pakugwiritsa ntchito zinthu, kusakaniza, ndi kusungunuka. Kukonzekera kwawo kwapadera, komwe kumadziwika ndi zomangira za intermeshing, kusuntha kwabwino, ndi kutentha kwabwino, kumawathandiza kuti azitha kuchita bwino pa ntchito zosiyanasiyana, kuphatikizapo pulasitiki ndi kuphatikizira, kusakaniza kwa polima ndi alloying, ndi extrusion yowonongeka. Monga otsogola opanga mapasa opangira ma screw extruder, Qiangshengplas yadzipereka kupatsa makasitomala athu ma extruder apamwamba okha komanso chithandizo ndi chitsogozo chokwanira. Ngati muli ndi mafunso kapena mukufuna thandizo lina posankha kapena kugwiritsa ntchito struder yamapasa, chonde musazengereze kulumikizana ndi gulu lathu la akatswiri odziwa zambiri.
