Isipiliyoni Sokukhiqiza Seminyaka engaphezu Kwengu-25

Ukutshalwa kwezimali kuma-extruder engeziwe e-MEAF 75-H34 kunganciphisa ukusetshenziswa kwamandla ekukhiqizweni kwamaselula kuze kufike ku-65% namandla aphindwe kabili.
Umkhiqizi wesemishi lekhekheba lezinyosi i-EconCore (Leuven, Belgium) kanye nomkhiqizi we-polypropylene honeycomb core i-ThermHex Waben GmbH (Halle, Germany) bawuphindaphinde kabili umthamo wabo wokukhiqiza owumgogodla wekhekheba lezinyosi futhi banciphisa ukusetshenziswa kwamandla ngo-65% uma kuqhathaniswa nezinye izixazululo.
Lezi zinkampani ezimbili zisanda kufaka ama-extruder we-MEAF (Jersek, The Netherlands) H-series esikhungweni sazo sokukhiqiza sesimanjemanje, kanti i-ThermHex ingeyesibili ngemva kokufakwa kokuqala ngo-2015.I-extruder entsha efakwe izici ezikhethekile ingaxhunywa. neyokuqala, inkampani iphawula, ukuhlanganisa imifudlana yokukhiqiza emibili ukuze kusetshenziswe amandla ngendlela ephumelela kakhulu.Lokhu kubikwa ukuthi kukhulisa umthamo wokukhiqiza we-ThermHex wezinyosi ze-honeycomb kusuka kumakhilogremu angu-500 (cishe amakhilogremu angu-1,100) ngehora kuya ku-1,000 kilogram (cishe amakhilogremu angu-2,200 ), okulingana nokukhiqizwa kwamashifu amabili amathani ayi-3,000 ngonyaka.
I-extruder ye-MEAF kuthiwa inikeza ulayini obalulekile we-extrusion wamandla ngaphezu kokuncintisana kwayo. Uma kuqhathaniswa ngqo, i-extruder ye-MEAF engu-75-H34 esetshenziswa yi-ThermHex Waben iqophe u-0.18-0.22 kW/kg, uma kuqhathaniswa no-0.50 kW/kg koqhudelana naye. ngaphezu kokudinga amandla angaphansi kuka-10-65% ukuze kukhiqizwe amakhilogremu omkhiqizo, ama-extruder we-MEAF H alungele ukukhipha izinto eziningi ngesikulufa kanye nomgqomo ofanayo, futhi ngenxa yomklamo wokungqubuzana ophansi we-extruder nokugeleza okuncane kanye nokuguquguquka kwengcindezi kunciphisa ukuwohloka kwe-polymer, ngisho nasekuphumeni okuphezulu.
I-EconCore, inkampani engumzali ye-ThermHex Waben, yethule i-MEAF 50 inkambiso 75-H34 extruder yayo yokuqala ngo-2017, ene-screw ratio efana ne-ThermHex MEAF laboratory extruder Kodwa imiphongolo emincane kanye nezici ezenziwe ngokwezifiso. imisebenzi yokukala ye-rPET honeycomb cores, i-EconCore idinga enye i-extruder yesikali esikhulu sezimboni enomklamo ohlangene.Idinga futhi ukucutshungulwa okusebenzayo kwama-flakes e-RPET kanye nohlu lwama-polymers anobunjiniyela ukuze kukhiqizwe i-RPET nezinyosi ezisezingeni eliphezulu ze-thermoplastic (HPT) .I-75-H34 inikeza lokhu kuyilapho igcina izilinganiso zesikulufa ezifanayo, imiphongolo nezici zangokwezifiso njengama-extruder adlule.
Inkinga eyodwa i-EconCore ebhekane nayo lapho ibheka i-extruder elungile kwaba izinga lokushisa layo elisezingeni eliphezulu lama-polymers asebenza kahle njenge-polyethyleneimine (PEI) .Nge-polypropylene, ama-extruder endabuko amaningi ngokuvamile ahlinzeka ngebanga lokushisa elingu-80-300 ° C. Nokho, lokhu kuphansi kakhulu futhi i-MEAF's ama-extruder ayakwazi ukuhlinzeka ngezinga lokushisa eliphakeme elingu-200-400°C, elidingekayo ukuze kukhishwe i-RPET kanye nohlu lwamapolymer obunjiniyela.
“Ubudlelwano bethu ne-MEAF abudluleli kithina kuphela kwa-EconCore nase-ThermHex Waben, kodwa nakubanikazi bamalayisensi bethu,” kusho uWouter Winant, uMphathi Wezobuchwepheshe kwa-EconCore.“Ubuchwepheshe bethu bokukhiqiza ama-honeycombs e-thermoplastic bunelayisensi.Ukuthembela kwethu kuma-extruders e-MEAF eminyakeni embalwa edlule kubonakala ekuzimiseleni kwethu ukuncoma imikhiqizo yabo kubo bonke abanamalayisensi.”
UDkt. Jochen Pflug, oyi-CEO ye-EconCore kanye ne-ThermHex Waben, uthe: “Isidingo sezinto ezisimeme, ezingasindi, neziqinile siyakhula, futhi kubalulekile ukuthi i-ThermHex Waben ikhuphule umthamo wethu wokukhiqiza ukuze sibhekane nokuthutheleka kwe isidingo,” kwengeza umgwaqo.”I-extruder ye-MEAF engu-75-H34 isivumele ukuthi sandise ngokuphawulekayo umthamo wethu wokukhiqiza.”
I-EconCore isanda kuqokelwa Umklomelo Webhizinisi Lezemvelo wase-Belgian ngobuchwepheshe bayo beselula be-rPET. Ngo-August 2021, ubuchwepheshe obuyisisekelo be-Econcore's rPET honeycomb nabo bathole isitifiketi se-Solar Impulse Label ngokuqaphela ukusimama kwezinto. I-ThermHex Waben isanda kushicilela izinkampani ezintsha eziyi-100 ezisungula izinto ezintsha kakhulu. Germany.
Bheka inqubo lapho izandulela ziguqulwa zibe imicu yekhabhoni ngokukhohlisa ngokucophelela (futhi ikakhulukazi okuphathelene) kwezinga lokushisa nokushuba.
Ukukhiqizwa kwezentengiselwano kwe-carbon fibre egaywe kabusha okwamanje kuyadlula ukusetshenziswa kwayo, kodwa ukubonakaliswa kwezinto ezibonakalayo nokuboniswa kobuchwepheshe obusha kuthembisa ukuvala igebe.
