Multi-layer blow blowingyakha udonga lwesitsha ngezingqimba zepulasitiki ezimbili noma ngaphezulu, ngasinye senza umsebenzi ohlukile - isendlalelo sokuvimbela ukuvimba umoya-mpilo noma umhwamuko kaphethiloli, umgogodla ogaywe kabusha ukuze unciphise izindleko, izikhumba ezimsulwa endaweni ehlanzekile. Akhishwa ndawonye ngekhanda elilodwa, ngakho udonga luphuma lungenamthungo futhi luhlangene. Uyayidinga lapho into eyodwa ingakwazi ukwenza yonke into: ithangi likaphethiloli okungafanele livuze umhwamuko, ibhodlela lejusi okufanele ligcine umoya-mpilo ungekho unyaka wonke, isiqukathi okufanele sishaye okuhlosiwe okugaywe kabusha ngaphandle kokungcolisa okungaphakathi. Imishini ye-KGH ye-KGH egobile yengalo isebenzisa izendlalelo ezi-1 kuya kweziyisi-6 ezitsheni ezisuka kumalitha ama-5 kuye kwangama-30.
Amabhodlela amaningi epulasitiki ayimpahla eyodwa, udonga olulodwa, olwenziwe. Cindezela i-HDPE ngedayizi, uyiqhumise, uyikhiphe. Kulula, kushibhile, futhi kulungele iziqukathi eziningi. Kodwa eminye imikhiqizo icela okuthile ipulasitiki elilodwa elingakwazi ukukunikeza. Futhi yilapho i-multi-layer ingena khona.
Sithola iqhinga eliqhubekayo labathengi abatshelwe ukuthi badinga "i-co-extrusion" noma "umshini wezingqimba eziyisithupha" futhi abaqiniseki ukuthi lokho kubathengani ngempela - noma ukuthi bayathengiswa yini. Ngakho-ke nansi inguqulo esobala: ukuthi izendlalelo zenzani, uma zikufanele, futhi uma ungcono ngokuhlala ungqimba olulodwa.
Okushiwo "ungqimba oluningi" empeleni okushiwo phansi kwefekthri
Ungqimba olulodwa i-extruder eyodwa epha ikhanda elilodwa lokufa ngento eyodwa. I-Multi-layer iyi-extruder eminingana - ngayinye incibilikisa inhlaka ehlukile ngezinga lokushisa layo - konke kudla okukodwa okwabiwe.co-extrusion die head. Ngaphakathi kwalelo khanda, imifudlana encibilikayo ehlukene inqwabelaniswa izendlalelo ezigxilile, ngakho-ke isonto liyawa selivele ligqizekile. Bese ivunguza njengawo wonke amanye amajele.
Cabanga ngakho njenge-plywood, ngaphandle kokuthi izendlalelo zenziwe futhi zihlanganiswe ngokudubula okukodwa kunokuba zihlanganiswe njengamashidi. Futhi amagama amabili ozowazwa - "i-multi-layer" kanye "ne-co-extrusion" - achaza into efanayo emikhawulweni ehlukene. I-Co-extrusion yindlela; ungqimba oluningi umphumela.
Izibalo zesendlalelo ngokuvamile zihlala ku-2, 3, 5, noma 6, futhi inombolo ngayinye inesizathu ngemuva kwayo. Sizofika kulokho. Okokuqala, izingqimba ngokwazo.
Ukuthi isendlalelo ngasinye singewani
Isendlalelo sokuvimbela - isizathu sokuba khona kwemisebenzi eminingi enezingqimba eziningi
I-Plain HDPE ne-PET zinhle ezintweni eziningi, kodwa zinombobo kancane kumagesi ngokuhamba kwesikhathi. Ngemikhiqizo eminingi, ubani okhathalelayo. Kwabanye, umdlalo webhola wonke. Ioksijeni enwabuzelayo imosha ukudla. Umhwamuko wesibaseli ophuma ethangini wephula imithetho yokukhipha umoya futhi uyinkinga yokuphepha. Isincibilikisi esinamandla sisebenza kancane kancane odongeni esingasithandi.
Yilokho okulungiswa ungqimba lwesithiyo.EVOH(i-ethylene vinyl alcohol) iyindinganiso yegolide yokuvimba umoya-mpilo nama-hydrocarbon;PA(inayiloni) enye inketho evamile. Nansi into yokubamba ekhuphula abantu: I-EVOH iyabiza, futhi izonda umswakama - umswakama uchitha ukusebenza kwayo kwesithiyo. Ngakho-ke awulokothi ukubeke phezulu. Uwugqiba phakathi nendawo, ugqinsi lwemilimitha, oluvikelwe nhlangothi zombili. I-EVOH core encane yenza ukuvimbela; I-HDPE eshibhile yenza ingxenye enkulu yodonga. Isendlalelo esincane, umphumela omkhulu.
Isendlalelo esigaywe kabusha / esigaywe kabusha - izindleko kanye ne-PPWR
Wonke umugqa wokugoqa ukhiqiza i-trim - imfucuza yokuncinza phezulu nomsila wengxenye ngayinye. Igaye futhi unezinto ezinhle kakhulu, hhayi nje izinto ozifunayo ukuthinta umkhiqizo noma uboniswe ngaphandle. Ngakho-ke uyondla futhi njengesendlalelo esiphakathi esingcwatshwe. Okokufaka kwamahhala, akukho ukuyekethisa ezindaweni ezibalulekile.
Iqhinga elifanayo liphatha okuqukethwe okugaywe kabusha kwangemuva komthengi. I-Sandwich PCR resin emnyombweni, gcina ipulasitiki yezinga lokudla elimsulwa esikhumbeni sangaphakathi nangaphandle, futhi ungakwazi ukushaya okuqondiwe kokuqukethwe okugaywe kabusha - okuhlanganisa nemikhawulo ye-EU esiyimboze engxenyeni yethu yokuthobela i-PPWR - ngaphandle kokuthi okokusebenza okugaywe kabusha kuke kuthinte okungaphakathi kwebhodlela. Ezinkampanini eziningi ezijaha iziyalezo ze-PCR ezingama-2030, izendlalelo eziningi ziyindlela ehlanzeke kunayo yonke ekhona.
Tie layers - lezo wonke umuntu azikhohlwayo
Manje ingxenye ebamba abathengi uma bebiza umsebenzi. I-EVOH nenayiloni azihlangani ne-polyethylene. Zibeke eceleni futhi zizohlukanisa - izingqimba zihlukana njenge-laminate engalungile, futhi ingxenye yonakalisiwe.
Ngakho-ke phakathi kwawo wonke amapheya wezinto ezingeke zinamathele, udinga aungqimba wokubopha: inhlaka encane enamathelayo ebamba izinhlangothi zombili. Yingakho ithangi likaphethiloli "lezendlalelo eziyisithupha" liyi-HDPE yangaphandle ngempela, i-regrind, tie, i-barrier, tie, i-HDPE yangaphakathi. Izingqimba zothayi ziyizingqimba nazo. Zishiye ngaphandle kohlelo lwakho futhi kungenzeka ukuthi unengxenye ehlukanayo noma isibalo sesendlalelo esingahlangani. Azikho inketho, futhi ziyinto yomugqa wangempela.
Lapho izingqimba eziningi zithola khona izindleko zazo
Amathangi kaphethiloli ezimoto (izigaba eziyisithupha zakudala)
Leli yicala lezincwadi zokufunda. Ithangi likaphethiloli lepulasitiki alikwazi ukuvumela umhwamuko we-hydrocarbon ukuthi ungene odongeni lwawo - imithetho yokukhipha umoya awukuvumeli, futhi kuwudaba lokuphepha. Ukwakhiwa okujwayelekile kuyisakhiwo se-HDPE, isendlalelo se-regrind, isendlalelo sikathayi, isithiyo se-EVOH, esinye isendlalelo sikathayi, kanye nesendlalelo se-HDPE sangaphakathi. Izendlalelo eziyisithupha, i-EVOH yenza ukuvinjwa kwe-permeation kanye nezingqimba zothayi ezibambe isemishi ndawonye. Ikhathalogi ye-Kinggle ibala amathangi kaphethiloli ngaphansi kwezingxenye zezimoto, futhi amathangi awuhlobo ncamashi lwengxenye esindayo, edinga ingxenye egobile yengalo yemishini enezingqimba eziningi eyakhelwe ukwenziwa.
Ukudla, isiphuzo kanye nephakheji yezimonyo
Iketchup, isoso, noma ibhodlela lejusi okufanele lihlale eshalofini unyaka wonke lidinga umgoqo womoya-mpilo, noma okuqukethwe yi-oxidise futhi konakale. Udonga olunezingqimba ezintathu (intombi / umgoqo / intombi) noma isakhiwo esigcwele esiyizendlalelo ezinhlanu sisingatha lokho. Izimonyo zifinyelela izendlalelo eziningi ngesizathu esihlukile futhi - isikhumba sangaphandle esinombala noma e-pearlescent phezu kwesendlalelo sangaphakathi esihlukile, noma "umugqa wokubuka" ocacile okhishwe ngokuhlanganyela phansi ohlangothini lwebhodlela elikhanyayo ukuze umsebenzisi abone ukuthi ungakanani umkhiqizo osele. Lowomugqa osebhodleleni lakho lokuhlanza? I-co-extruded.
Iziqukathi ze-agrochemical nezekhaya-zamakhemikhali
Isibulala-zinambuzane esinolaka noma isincibilikisi singangena noma siqhekeke udonga lwe-HDPE olungenalutho phakathi nezinyanga zokugcinwa. Isithiyo noma isendlalelo esine-fluorinated sithenga ukumelana namakhemikhali nempilo yeshelufu, yingakho ukupakishwa okuningi kwe-agrochemical kune-multi-layer kunokuba eyodwa. Lawa mabhodlela amakhemikhali ansuku zonke nawe-agrochemical ahlala khona kanye ngaphakathi kwezinhlelo zokupakisha ze-Kinggle - imindeni yesiqukathi efanayo nemishini emincane yengalo egobile esebenza usuku lonke.
Ngakho zingaki izendlalelo ozidingayo ngempela?
Izendlalelo ezengeziwe zisho ama-extruder amaningi, izindleko ezengeziwe, nokuguquguquka okwengeziwe okumele kushune. Inombolo elungile imbalwa eyenza umsebenzi - hhayi kakhulu umthengisi angakudayisela. Cishe:
| Izendlalelo | Ukusetshenziswa okuvamile | Kungani |
|---|---|---|
| 1 | Amanzi, izinto zokuhlanza eziningi, amathini ejerry angenalutho | Into eyodwa yenza konke okudingekayo |
| 2–3 | Phinda usebenzise kabusha, ukuhlukaniswa kombala/ubuso, umgoqo wokukhanya | Fihla umongo ogaywe kabusha, noma engeza umgoqo onesizotha |
| 5 | Ukudla nesiphuzo esinomkhawulo ogcwele womoya-mpilo | Isithiyo + bopha izendlalelo ezinhlangothini zombili |
| 6 | Amathangi kaphethiloli, imisebenzi efuna ukungena | Isithiyo + izibopho + regrind + isakhiwo |
Uma into eyodwa isivele ihlangabezana nempilo yeshalofu yomkhiqizo wakho, ukumelana namakhemikhali, nezidingo zokuqukethwe okugaywe kabusha, ungazikhokheli izendlalelo ongeke uzisebenzise. I-Multi-layer iyithuluzi lezinkinga ezithile, hhayi ukuthuthukisa ngenxa yayo.
Yiziphi izingqimba eziningi ezifunwa emshinini
Nansi into umdwebo wesendlalelo ongeke ukutshele wona: ungqimba ngalunye ludinga i-extruder yalo yokondla i-co-extrusion die head. Ithangi elinezingqimba eziyisithupha lingasho ama-extruder amahlanu noma ayisithupha ahlangene azungeze ikhanda elilodwa, ngalinye lincibilikisa inhlaka ehlukile ngezinga lokushisa lalo, ngalinye lilinganiswe ngokunembile ukuze ungqimba lwalo luhlale luwugqinsi olulinganayo yonke indlela ezungeze isonto. Lowo umshini ohluke kakhulu emugqeni webhodlela wesendlalelo esisodwa.
I-Kinggle'sUchungechunge lwengalo egobile ye-KGHyakhelwe lo msebenzi - izingqimba ezi-1 kuye kweziyi-6 ezitsheni ezisuka ku-5 kuya ku-30 wamalitha. Izinombolo ezingemuva kwayo ngezangempela: amandla okubamba asuka ku-200 kuye ku-300 kN kulo lonke uhla, i-HDPE ifaka ipulasitiki efika ku-300 kg/h ku-KGH30D, kanye nohlelo lokuqina odongeni olulawulwa yi-MOOG. Lokho kulawulwa kogqinsi kubaluleke kakhulu ku-multi-layer kunokukodwa, ngoba ubambe izendlalelo ezimbalwa ezincanyana - okuhlanganisa umgoqo ongase ube ingxenye yemilimitha - ukucacisa ngesikhathi esifanayo, yonke indlela ezungeze ingxenye. Kwenze kungalungile futhi umgoqo wakho uyancipha ehlombe, okuyilapho ungafuni khona igebe.
Kuyafaneleka futhi ukwazi ukuthi yini engaphakathi kwesistimu yokulawula, ngoba izingqimba eziningi zihlala noma zifa ngokubambisana okuqondile phakathi kwama-extruder. Imishini ye-Kinggle isebenza ezingxenyeni zezinga lezimboni - i-Mitsubishi PLC, i-MOOG servo control, i-OMRON kanye ne-Schneider kagesi - uhlobo lwekhithi egcina ama-extruder amahlanu emitha ku-shift yokuvumelanisa ngemva kokushintsha.
Amaphutha amane esiwabukayo abathengi
- Ukuthenga izendlalelo ongazidingi.Uma i-HDPE engenalutho ihlangabezana nempilo yakho yeshelufu kanye nemigomo yokuqukethwe okugaywe kabusha, umshini onezingqimba eziyisithupha uyimali ehlezi ingenzi lutho. Qondanisa izendlalelo nenkinga yangempela.
- Ukukhohlwa izendlalelo zokubopha kusabelomali.Ziyizendlalelo zangempela nezindleko zangempela, futhi ukuzishiya kuyindlela eshesha kakhulu eya engxenyeni elimazayo. Wabale kusukela ekuqaleni.
- Ukubeka umgoqo endaweni engafanele.I-EVOH endaweni noma eduze kwayo, lapho umswakama ufinyelela khona, ilahla ukusebenza okukhokhele. Ingowomgogodla ovikelekile.

Uma usanquma phakathi kwezinhlobo zemishini ngaphambi kokufika ngisho nasezindaweni, umhlahlandlela wethu wokuthii-accumulator vs imishini yokubumba eqhubekayoindawo efanele ukuqala, futhivuthela ukubumba vs ukubumba umjovoUhlolojikelele luhlanganisa ukukhetha kwenqubo izinga elilodwa ukuya phezulu.
Imibuzo ejwayelekile ukubuzwa
Uyini umehluko phakathi kokubumba kwe-multi-layer kanye ne-co-extrusion blow?
Bachaza into efanayo. I-Co-extrusion iyindlela - ama-extruder ambalwa ngalinye lincibilikisa inhlaka ehlukile futhi liphakele ikhanda elilodwa elihlanganyelwe lokufa, eliwanqwabelanisa abe yizingqimba ezigxilile. I-Multi-layer ichaza umphumela - udonga lwesitsha olwakhiwe ngezingqimba ezimbili noma ngaphezulu ezihlanganisiwe. Uma udonga lunongqimba olungaphezu kwesisodwa, lukhishwe ngokuhlanganyela.
Kungani ungqimba lwesithiyo lwe-EVOH lugqitshwe phakathi nendawo esikhundleni sangaphezulu?
Izizathu ezimbili. I-EVOH iyabiza, ngakho usebenzisa kancane ngangokunokwenzeka - umgogodla omncane wenza umsebenzi wokuvimbela kuyilapho i-polyethylene eshibhile yenza inqwaba. Futhi i-EVOH idonsa umswakama, ocekela phansi ukusebenza kwayo kwesithiyo, ngakho-ke kufanele ivikelwe nhlangothi zombili ngezinye izendlalelo. Ukuyibeka phezulu bekuyoyimosha futhi ibeke endaweni enomswakama.
Ziyini izendlalelo zikathayi futhi ngingazeqa?
Izendlalelo zikathayi ziyizingqimba zenhlaka ezinamathelayo ezincane ezinamathelayo ezingeke zinamathele ndawonye - I-EVOH nenayiloni azihlangani ne-polyethylene ngokwazo. Yeqa futhi izendlalelo zihlakazeke, zihlukanise njenge-laminate ehlulekile. Azikho ozikhethela zona. Ithangi likaphethiloli elinezendlalelo eziyisithupha lihlanganisa izendlalelo zokubopha phakathi kwawo wonke amapheya ahlukene, okuyingxenye yokuthi kungani linezendlalelo eziyisithupha.
Zingaki izendlalelo ithangi likaphethiloli lepulasitiki?
Ngokuvamile eziyisithupha. Isakhiwo esivamile isendlalelo se-HDPE sangaphandle, isendlalelo se-regrind, isendlalelo sokubopha, isithiyo se-EVOH, isendlalelo se-tie sesibili, kanye nesendlalelo se-HDPE sangaphakathi. I-EVOH imisa umhwamuko we-hydrocarbon ukuthi ungangeni odongeni, izendlalelo zikathayi ziwubambe uye ku-polyethylene, futhi isendlalelo se-regrind sisebenzisa kabusha ukusika kokukhiqiza.
Ngingakwazi ukusebenzisa izinto ezigaywe kabusha esitsheni sezendlalelo eziningi?
Yebo, futhi i-multi-layer iyindlela ehlanzekile kakhulu yokwenza. Ungcwaba izinto ezigaywe kabusha noma zangemva komthengi (i-PCR) endaweni emaphakathi futhi ugcine inhlaka emsulwa, yezinga lokudla endaweni engaphakathi nangaphandle. Ingqikithi egaywe kabusha ayilokothi ithinte umkhiqizo noma imibukiso ngaphandle, ukuze ukwazi ukushaya okuqondiwe kokuqukethwe okugaywe kabusha ngaphandle kokufaka engcupheni ukungcola.
Awuqinisekile ukuthi zingaki izendlalelo umkhiqizo wakho ozidingayo?
Sitshele ukuthi isiqukathi kufanele sibambe ini nokuthi yini okufanele siyigcine ingaphakathi noma iphuma - umoya-mpilo, umhwamuko kaphethiloli, ikhemikhali enolaka, okuqondiwe kokuqukethwe okugaywe kabusha - futhi onjiniyela bethu bazokutshela isakhiwo sesendlalelo nokuthi yimuphi umshini owakhayo. Senza imishini yokubumba i-blow molding kusukela ngo-2002, nonjiniyela abangu-15 eqenjini.
Buza onjiniyela bethu mayelana nokusethwa kwezendlalelo eziningi →Izendlalelo eziningi aziyona into ethandwa ungqimba olulodwa — iyithuluzi elihlukile lemikhiqizo into eyodwa engakwazi ukuyinikeza. Uma wazi ukuthi ungqimba ngalunye lukhona okumele lwenziwe, umbuzo uyayeka ukuthi "bangaki izendlalelo?" futhi iba "yini ngempela lesi siqukathi okufanele siphile?" Phendula lokho, futhi isakhiwo siyazikhethela. Phequlula ngokugcweleuhla lomshini wokubumbauma usulungele ukufanisa umshini kuwo.
