Ama-extruder anezigaba ezimbili asetshenziswa kakhulu ekuxubeni nasekuchebeni ama-thermoplastics. Isakhiwo esinezigaba ezimbili sifanelekile ukucubungula izinto ezihlukahlukene, njengezinto zekhebula le-PVC ne-XLPE, izinto zezokwelapha ezithambile ze-PVC, I-PVC eqinile kanye ne-PE low-smoke halogen-free fuel resistant, njll.
Ngokuphela 18 iminyaka yobungcweti kubuchwepheshe be-plastic extrusion kanye nokusebenzisana okuqondile ne 200+ abakhiqizi bomhlaba (kuhlanganise nezimoto, ikhebula, kanye nabakhiqizi bemishini yezokwelapha), Ngiwubonile umthelela oguquguqukayo wama-extruder amabili esiteji ekuhlanganiseni ukusebenza kahle kanye nekhwalithi yezinto ezibonakalayo. Ngokungafani nesistimu ye-extrusion yesiteji esisodwa, idizayini ye-tandem extrusion ibhekana nenselelo ebalulekile yokulinganisa amandla aphezulu ngokugunda okulawulwayo kanye nokuphathwa kwezinga lokushisa—okuyenza ibe izinga eligolide lokucubungula ama-thermoplastics azwelayo noma asebenza kakhulu njenge-PVC., I-XLPE, kanye nentuthu ephansi enguziro-halogen (I-LSZH) izinto zokwakha.
I I-Stage Tandem Extruder Factory emibili imele isixazululo esikhethekile se-extrusion esakhelwe ukuhlanganisa ngokunemba kanye nokugunda kwe-thermoplastics, lapho ukulawulwa kwenqubo nobuqotho bezinto ezibonakalayo kungaxoxiswana khona. Ukucushwa kwezigaba ezimbili zesistimu kuhlukanisa inqubo ye-extrusion ibe izingxenye ezimbili ezihlukene, izigaba ezihambisanayo, ngayinye ithuthukiselwe umsebenzi othile—ukuqeda ukuhwebelana okukhona kuma-extruder esiteji esisodwa.
I-extruder yesiteji sokuqala iwele ivamise ukugijima ngesivinini esiphezulu ukuze kuhlanganiswe kangcono kanye nokuphuma okuphezulu. Lesi sigaba se-tn-screw esinesivinini esikhulu sihamba phambili ekuxubeni okujulile, i-homogenization, kanye nokuncibilika kwezinto ezingavuthiwe, leveraging intermeshing screw geometry ukuqinisekisa ukusatshalaliswa okufanayo kwezithasiselo, izigcwalisi, noma ama-reinforcements (isib., ingilazi fiber, ama-flame retardants). Isivinini esikhulu sokujikeleza (kuya ku 500 rpm yamamodeli we-Zhuoyue) ikhulisa ukusebenza kahle kokuhlanganisa, icubungula ukwakheka kwezinto eziyinkimbinkimbi esikalini.
Isigaba sesibili kufanele kube yi-scruder eyodwa yesikulufu, enobubanzi obukhulu kanye nokusebenza kwejubane eliphansi. Isivinini esiphansi sesikulufu sigwema ukugunda ngokweqile—inzuzo ebalulekile yezinto ezizwela ukushisa njenge-PVC ethambile yezinga lezokwelapha noma izinhlanganisela zekhebula le-XLPE, lapho ukugunda ngokweqile kungathunaza ukwakheka kwamangqamuzana, ukuyekethisa izakhiwo zemishini, noma abangele ukuwohloka kokushisa. Ngenxa yekhono eliqinile lokushintshanisa ukushisa, uhlelo lokupholisa lwangaphakathi lungavimbela ngokuphumelelayo ukushisa ngokweqile, ukugcina ukulawulwa kwezinga lokushisa okunembile kuwo wonke umgqomo wesigaba sesibili ukuze kuqinisekiswe ukuncibilika okungaguquki kwe-viscosity kanye nekhwalithi yomkhiqizo.
I Umkhiqizi we-Tandem Extruder wezigaba ezimbili ivumela opharetha ukuthi enze izinto ezivumelana nezimo, izinqubo zokuhlanganisa ezibikezelwayo nokulawula izinga lokushisa. Ngokuhlukanisa ukuhlanganisa (esiteji 1) kanye nokubunjwa/extrusion (esiteji 2), opharetha bangakwazi ukulungisa amapharamitha ngokuzimela (isivinini, izinga lokushisa, isilinganiso sokuphakelayo) esigabeni ngasinye, ukwenza inqubo ihambisane nezidingo eziyingqayizivele zento ngayinye—kusuka ezingxenyeni eziqinile zamapayipi e-PVC kuye kwezithambile ze-PVC yebanga lezokwelapha noma izinto zekhebula le-LSZH.
Isiteji sokuqala se-twin-screw esinesivinini esikhulu siletha ukuxutshwa okujulile okungeke kufane ne-single-screw extruder., ukuqinisekisa ukuhlakazeka okufanayo kwezithasiselo (isib., ama-plasticizers, izinza, ama-flame retardants) kanye nezakhiwo ezihambisanayo ze-batch-to-batch. Ukuhlolwa komuntu wesithathu okwenziwa yi-China Plastic Machinery Industry Association (I-CPMIA) iqinisekisa ukuthi ama-extruder amabili esiteji kaZhuoyue ayazuza 98% ukunemba kwe-homogenization kwenhlanganisela ye-PVC-15% ephakeme kunezinye izindlela zesiteji esisodwa.
Isigaba sesibili se-speed single-screw siqeda ukucheba ngokweqile nokushisa ngokweqile, ukuvikela izinto ezizwela ukushisa ekonakalisweni. Ngokwesibonelo, lapho kucutshungulwa izinto zokwelapha ezithambile ze-PVC (esetshenziswa kumashubhu e-IV noma kumishini yokuhlinza), isistimu igcina ukuhluka kwezinga lokushisa okungu-±1°C, ukuqinisekisa ukuthotshelwa kwe-ISO 10993 amazinga e-biocompatibility nokugwema ukuguquguquka kwempahla noma ukonakala.
Idizayini ye-tandem ihlanganisa ukusebenza kahle kokuhlanganiswa okuphezulu (esiteji 1) nge-extrusion engaguquki (esiteji 2), ukuletha 30-50% okuphumayo okuphezulu kunama-twin-screw extruder esiteji esisodwa anosayizi olinganayo. Imodeli ye-Zhuoyue ZYT65-150 iyakhiqiza 300-500 kg/hr yezinto zekhebula le-XLPE—uma kuqhathaniswa 200-300 kg/hr kusuka ku-extruder yesiteji esisodwa esingu-65mm twin-screw—ngenkathi kugcinwa ukulawula okuqinile kwekhwalithi phezu kwezakhiwo zokuvala ugesi.
Ukulungiswa kwepharamitha eguquguqukayo kanye nomklamo wezigaba ezimbili kwenza isistimu ihambisane nezinhlobonhlobo ze-thermoplastics, kusuka kuma-resin wempahla kuya ezintweni zobunjiniyela ezisebenza kahle kakhulu. Lokhu kuguquguquka kuqeda isidingo sama-extruder amaningi azinikele, ukunciphisa ukusetshenziswa kwemali enkulu kanye nesikhala saphansi sefekthri kubakhiqizi abacubungula ukwakheka kwezinto ezihlukene.
Izinga lokushisa elinembile nokulawula ukugunda kunciphisa izinsalela zezinto (ngokuvamile <2% yezinhlelo zeZhuoyue, uma kuqhathaniswa 5-8% ama-extruder esiteji esisodwa) kanye nokunciphisa ukusetshenziswa kwamandla 18% nge-kg ye-compound eqediwe. Ngokukhiqizwa kwevolumu ephezulu (isib., ukukhiqizwa kwezinto zekhebula), lokhu kusho ukonga izindleko zonyaka ze $50,000-$150,000 ngezinsiza ezimaphakathi.
I-extruder yesiteji ezimbili isetshenziselwa ikakhulukazi ukuhlanganiswa kwe-thermoplastic nokugunda. isakhiwo esinezigaba ezimbili sifanelekile ukucubungula izinto ezihlukahlukene, ngezinhlelo zokusebenza ezihlanganisa ukunemba okuphezulu nezimboni zevolumu ephezulu lapho ukuvumelana kwezinto kubalulekile:
Uchungechunge lwe-extruder yesiteji ezimbili zika-Zhuoyue (ZYT50-120 ukuze ZYT95-200) yakhelwe ukukala nezidingo zokukhiqiza, kusuka ekuhlanganiseni okukhethekile kwenqwaba (ZYT50-120) ekukhiqizeni izimboni ezinkulu (I-ZYT95-200). Wonke amamodeli agcina izimiso zokuklama eziwumgogodla wezigaba ezimbili—ukuhlanganisa ngesivinini esikhulu, i-extrusion enesivinini esiphansi, kanye nokupholisa okunembayo—okunemininingwane eklanyelwe ukukhiqiza nohlobo lwempahla:
