A i-conical twin screw extruderiwuhlobo lwe-twin screw extruder enezikulufu ezimbili ezihlelwe ngendlela eyi-conical, ezihambela ngasekugcineni kokukhipha kwe-extruder.Lo mklamo uhlinzeka ngokuncipha kancane kancane kwevolumu yesikulufu sesiteshi, okuholela ekwenyukeni kwengcindezi nokuhlanganisa okuthuthukisiwe.I-conical twin screw extruder yakhiwa ikakhulukazi isikulufu somgqomo, isistimu yokudlulisa igiya, ukuphakelwa komthamo, i-vacuum exhaust, ukufudumeza, ukupholisa kanye nezingxenye zokulawula zikagesi.
I-conical twin screw extruder ifaneleka ukukhiqiza imikhiqizo ye-PVC kusuka kumpushana oxubile.I-PVC iyi-polymer ye-thermoplastic enezinhlobonhlobo zezicelo ezimbonini ezahlukahlukene, njengokwakha, ukupakisha, ugesi, izimoto, kanye nezokwelapha.Kodwa-ke, i-PVC ayihambisani namanye ama-polymer amaningi nezithasiselo, futhi idinga amasu okucubungula akhethekile ukuze kuzuzwe izakhiwo ezifiselekayo nokusebenza.I-conical twin screw extruder ingahlinzeka ngokuxutshwa okudingekayo, ukuncibilika, ukubola, kanye ne-homogenization ye-PVC nezithasiselo zayo ngendlela eqhubekayo nephumelelayo.
I-conical twin screw extruder nayo iyisisetshenziswa esikhethekile se-WPC powder extrusion.I-WPC imele i-wood-plastic composite, okuwumsebenzi ohlanganisa imicu yokhuni noma ufulawa wokhuni nama-polymers ashisayo, njenge-PVC, i-PE, i-PP, noma i-PLA.I-WPC inezinzuzo zakho kokubili ukhuni nepulasitiki, njengamandla aphezulu, ukuqina, ukumelana nesimo sezulu, kanye nokusebenziseka kabusha.I-conical twin screw extruder ingacubungula i-WPC powder enomphumela ophezulu, ukusebenza okuzinzile, nempilo ende yesevisi.
Ngemishini ehlukene yokubunjwa neyezansi nomfula, i-conical twin screw extruder ingakhiqiza imikhiqizo ehlukahlukene ye-PVC ne-WPC, njengamapayipi, usilingi, amaphrofayili ewindi, ishidi, ukudeka, nama-granules.Le mikhiqizo inomumo, osayizi, nemisebenzi ehlukene, futhi ingahlangabezana nezidingo ezahlukahlukene zamakhasimende nezimakethe.
Incazelo Yenqubo
Inqubo ye-conical twin screw extrusion ingahlukaniswa ngezigaba ezine eziyinhloko: ukuphakela, ukuncibilika, ukubola, nokubunjwa.
Ukondla
Isigaba sokuqala se-conical twin screw extrusion esokuphakela.Kulesi sigaba, izinto zokusetshenziswa, njenge-PVC noma i-WPC powder, nezinye izithasiselo, njengeziqinisi, izinto zokugcoba, izihlungi, izimibalabala, nezishintshi, ziyabalwa futhi zifakwe ku-extruder ngamadivayisi ahlukene okuphakelayo, njengama-screw augers, vibratory. amathreyi, amabhande okukala, namaphampu omjovo.Izinga lokudla kanye nokunemba yizici ezibalulekile ezithinta ikhwalithi nokuvumelana kwemikhiqizo yokugcina.Izinto ezingavuthiwe zingaxutshwa ngaphambili futhi ziphakelwe, noma zilinganiswe ngokuhlukana futhi zilinganiswe ngokulandelana ku-extruder, kuye ngokwakhiwa kanye nezakhiwo ezifunwayo zemikhiqizo.
Iyancibilika
Isigaba sesibili se-conical twin screw extrusion siyancibilika.Kulesi sigaba, izinto zokusetshenziswa zidluliswa, zicindezelwe, futhi zishisiswe ngezikulufu ezijikelezayo kanye nezifudumezi zemiphongolo, futhi ziguqulwe zisuka kokuqinile ziye esimweni soketshezi.Inqubo yokuncibilika ibandakanya kokubili okokufaka kwamandla ashisayo nokomshini, futhi kuthonywa isivinini sesikulufu, ukumiswa kwezikulufu, izinga lokushisa lomgqomo, kanye nezakhiwo ezibonakalayo.Inqubo yokuncibilika ibalulekile futhi ekuhlakazweni nasekusabalaliseni izithasiselo ku-matrix ye-polymer, kanye nokuqaliswa kokusabela kwamakhemikhali, njengokuxhumanisa, ukuxhunyelelwa, noma ukuwohloka, okungenzeka ekuncibilikeni.Inqubo yokuncibilika kufanele ilawulwe ngokucophelela ukuze kugwenywe ukushisa ngokweqile, ukugunda kakhulu, noma ukuncibilika kancane kwezinto, okungase kubangele izinga eliphansi lomkhiqizo nokusebenza.
I-Devolatilization
Isigaba sesithathu se-conical twin screw extrusion i-devolatilization.Kulesi sigaba, izingxenye eziguquguqukayo, ezinjengomswakama, umoya, ama-monomers, izinyibilikisi, nemikhiqizo ebolayo, ziyasuswa ekuncibilikeni ngokusebenzisa i-vacuum ezimbotsheni zokungenisa umoya eduze kombhobho ophumayo.Inqubo ye-devolatilization ibalulekile ekwenzeni ngcono izinga lomkhiqizo nokuzinza, kanye nokunciphisa umthelela wemvelo kanye nezingozi zezempilo zenqubo yokukhishwa.Inqubo ye-devolatilization incike ekwakhiweni kwesikulufu, izinga le-vacuum, i-viscosity encibilikayo, kanye nezici ezibonakalayo.Inqubo ye-devolatilization kufanele ithuthukiswe ukuze kuzuzwe ukususwa okwanele kweziguquguqukayo ngaphandle kokubangela amagwebu amaningi, ukugcwala kwe-vent, noma ukuncibilika kokuncibilika.
Ukubumba
Isigaba sesine nesokugcina se-conical twin screw extrusion siyabumba.Kulesi sigaba, ukuncibilika kukhishwa nge-die noma isikhunta esinquma ukuma nobukhulu bomkhiqizo.I-die noma isikhunta ingaklanywa ukukhiqiza imikhiqizo ehlukahlukene, njengamapayipi, amaphrofayili, ishidi, ifilimu, noma ama-granules.Inqubo yokubumba ithonywa yi-die geometry, ingcindezi yokufa, izinga lokushisa lokufa, kanye ne-melt rheology.Inqubo yokuma kufanele ilungiswe ukuze kuzuzwe ama-extrudates afanayo futhi abushelelezi ngaphandle kweziphambeko, njengokuvuvukala kokufa, ukuphuka kwe-ncibilika, noma ukungazinzi kwe-dimensional.Ngemva kwenqubo yokubunjwa, ama-extrudates ayapholiswa, asikwe, futhi aqoqwe izinto ezisebenza ezansi nomfula, njengama-calibrator, ama-hauult, ama-cutters, nama-winder.
Isiphetho
I-conical twin screw extruder iyisisetshenziswa esisebenza ngezindlela eziningi nesisebenza kahle sokukhiqiza imikhiqizo ye-PVC ne-WPC kusuka kumpushana oxubile.Ingahlinzeka ngemisebenzi edingekayo yokondla, ukuncibilika, ukucekela phansi amandla, kanye nokubunjwa ngendlela eqhubekayo nelawulwayo.Ingakwazi futhi ukukhiqiza imikhiqizo ehlukahlukene enobumo obuhlukahlukene, ubukhulu, nemisebenzi, ngokusebenzisa isikhunta esihlukile kanye nemishini engaphansi komfula.I-conical twin screw extruder inezinzuzo zokuhlanganisa okuhle, okukhiphayo okukhulu, ukusebenza okuzinzile, nempilo ende yesevisi, futhi ingahlangabezana nezidingo ezihlukahlukene zamakhasimende nezimakethe.
