Kev nqis peev hauv ntxiv MEAF 75-H34 extruders tuaj yeem txo qis kev siv hluav taws xob hauv cellular ntau lawm txog li 65% thiab muaj peev xwm ob npaug.
Honeycomb sandwich producer EconCore (Leuven, Belgium) thiab polypropylene honeycomb core chaw tsim tshuaj paus ThermHex Waben GmbH (Halle, Lub teb chaws Yelemees) tau muab ob npaug rau lawv cov honeycomb core muaj peev xwm ntau lawm thiab txo lub zog noj los ntawm 65% piv rau lwm txoj kev daws teeb meem.
Ob lub tuam txhab tsis ntev los no tau teeb tsa MEAF (Jersek, Lub Netherlands) H-series extruders hauv lawv qhov chaw tsim khoom hauv xeev, nrog ThermHex yog qhov thib ob tom qab thawj qhov kev teeb tsa hauv 2015.A tshiab extruder nruab nrog cov yam ntxwv tshwj xeeb tuaj yeem txuas nrog. nrog rau thawj zaug, lub tuam txhab sau tseg, txhawm rau ua ke ob txoj kev tsim khoom siv rau kev siv lub zog zoo tshaj plaws.Qhov no tau tshaj tawm tias cov theoretical ntau lawm muaj peev xwm ntawm ThermHex honeycomb cores los ntawm 500 kilograms (kwv yees li 1,100 phaus) ib teev mus rau 1,000 kilograms (kwv yees li 2,200 phaus. ), sib npaug rau ob-hloov ntau lawm ntawm 3,000 tons hauv ib xyoos.
MEAF extruder tau hais kom muab cov ntawv tseem ceeb extrusion kab hluav taws xob ua haujlwm dhau ntawm nws qhov kev sib tw.Hauv kev sib piv ncaj qha, MEAF's 75-H34 extruder siv los ntawm ThermHex Waben tau sau tseg 0.18-0.22 kW / kg, piv rau 0.50 kW / kg rau cov neeg sib tw. Ntxiv rau qhov xav tau 10-65% tsawg zog los tsim cov khoom hnyav hnyav, MEAF H series extruders yog tsim rau extruding ntau yam ntaub ntawv nrog tib lub taub hau thiab lub thoob, thiab vim lub extruder tsis tshua muaj kev sib txhuam tsim thiab tsawg kawg nkaus ntws thiab siab fluctuations txo polymer degradation, txawm nyob rau ntawm cov zis ntau dua.
EconCore, lub tuam txhab niam txiv ntawm ThermHex Waben, tau pib nws thawj MEAF 50 kev cai 75-H34 extruder rau nws txoj kab tsav hauv xyoo 2017, uas muaj tib tus ntsia hlau piv rau ThermHex MEAF lub chaw kuaj extruder Tab sis cov thoob me me thiab kev cai nta.Muab lub tuam txhab kev lag luam ntxiv. scale-up kev ua ub no rau rPET honeycomb cores, EconCore yuav tsum tau muaj lwm yam loj-scale extruder nrog ib tug compact tsim.Nws kuj yuav tsum tau npaum li cas ntawm RPET flakes thiab ib tug ntau yam ntawm engineered polymers rau zus tau tej cov RPET thiab siab ua tau zoo thermoplastic (HPT) honeycomb cores .The 75-H34 muab qhov no thaum tuav tib cov ntsia hlau sib piv, chim thiab kev cai nta raws li yav dhau los extruders.
Ib qho teeb meem EconCore ntsib thaum nrhiav txoj cai extruder yog nws qhov kub thiab txias rau kev ua haujlwm siab polymers zoo li polyethyleneimine (PEI).Rau polypropylene, ntau cov tshuaj extruders feem ntau muab qhov kub ntawm 80-300 ° C.Txawm li cas los xij, qhov no tsawg dhau thiab MEAF's extruders muaj peev xwm muab tau qhov kub thiab txias ntau ntawm 200-400 ° C, uas yuav tsum tau extrude RPET thiab ntau yam engineering polymers.
"Peb txoj kev sib raug zoo nrog MEAF txuas ntxiv tsis yog rau peb tus kheej ntawm EconCore thiab ThermHex Waben, tab sis kuj rau peb cov ntawv tso cai," said Wouter Winant, Technical Manager ntawm EconCore. "Peb cov thev naus laus zis rau kev ua haujlwm tsis tu ncua ntawm cov thermoplastic honeycombs tau ntawv tso cai. Hauv Peb txoj kev ntseeg siab hauv MEAF extruders ob peb xyoos dhau los no tau cuam tshuam los ntawm peb txoj kev txaus siab los qhia lawv cov khoom rau txhua tus neeg muaj ntawv tso cai. "
Dr. Jochen Pflug, CEO ntawm EconCore thiab ThermHex Waben, tau hais tias: "Qhov kev thov kom muaj kev ruaj khov dua, lub teeb yuag, cov ntaub ntawv muaj zog loj zuj zus tuaj, thiab nws yog ib qho tseem ceeb rau ThermHex Waben los ua kom peb lub peev xwm ntau lawm txhawm rau tiv thaiv kev nkag mus ntawm cov khoom siv. thov, "ntxiv txoj kev." MEAF's 75-H34 extruder tau tso cai rau peb nthuav peb cov peev txheej ntau lawm. "
EconCore tsis ntev los no tau raug xaiv tsa rau Belgian Environmental Business Award rau nws rPET cellular technology.Lub Yim Hli 2021, Econcore's rPET honeycomb core thev naus laus zis kuj tau txais ntawv pov thawj rau Hnub Ci Impulse Label hauv kev lees paub ntawm cov khoom siv tau ruaj khov. Lub teb chaws Yelemees.
Ua tib zoo saib cov txheej txheem los ntawm cov precursors tau hloov mus rau carbon fibers los ntawm kev ceev faj (thiab feem ntau yog tswv) kev tswj ntawm qhov kub thiab txias.
Kev lag luam tsim cov khoom siv roj carbon fiber ntau tam sim no outpaces nws daim ntawv thov, tab sis cov khoom siv thiab ua qauv qhia ntawm cov thev naus laus zis tshiab cog lus tias yuav kaw qhov sib txawv.
