Kupanga ulusi wa poliyesitala wofuna nsalu kuchokera ku ma granules a PET (rPET), makamaka pogwiritsa ntchito mzere.kupota ndondomeko, ndi ntchito yovuta kwambiri.Izi zimafuna ukadaulo wopanga komanso chidziwitso cha mphero yozungulira.Zomwe zimayambira ziyenera kusinthidwa mosalekeza kukhala chosungunula chosungunuka.
Zonsemasitepe processingayenera kupereka katundu wofunidwa wa kusungunula ndikusunga zinthuzi kukhala zokhazikika panthawi yonseyi.Pazovala zambiri za nsalu, magawo monga viscosity ndi kufanana ndizosankha ndipo ziyenera kutengera kusinthasintha pang'ono.M'mawu ena: Kugwiritsa ntchito poliyesitala wobwezerezedwanso m'gawo la nsalu kumafuna njira zoyenera zodzitchinjiriza komanso kuwongolera njira zolondola.
BB Engineering, kampani ya Oerlikon Textile, ili ndi zaka zambiri komanso ukadaulo pakupanga zigawo ndi makina opangira mphero.Unali kudziwa kozungulira uku komwe kunali kofunikira pakukulitsa bwino kwa makina obwezeretsanso a VacuFil PET.Pazifukwa izi, kampaniyo yapanga makina obwezeretsanso amadzimadzi a polycondensation kuti apititse patsogolo zinyalala zopota pambuyo popanga ndi ma flakes a botolo, omwe ali oyenererana ndi mphero zopota zopangira nsalu zina zobwezerezedwanso (patent ikuyembekezera).
Mtima wa ndondomekoyi ndi fyuluta ya vacuum, yomwe imayang'anira payekha ndikuwongolera kukhuthala.Kuti izi zitheke, zomwe mukufuna kusungunula zitha kupezedwa pa intaneti modalirika komanso kubwezanso ndikuwunikidwa pakugwira ntchito. M'mayesero osiyanasiyana ozungulira, ma granulate a rPET opangidwa ku Oerlikon Textile R&D Center pogwiritsa ntchito VacuFil adatulutsa zotsatira zokhutiritsa. M'mayesero osiyanasiyana ozungulira, ma granulate a rPET opangidwa ku Oerlikon Textile R&D Center pogwiritsa ntchito VacuFil adatulutsa zotsatira zokhutiritsa. Вразличных испытаниях на прядение гранулы rPET, komanso ku Oerlikon Textile R&D Center ndi VacuFil, дали убедительные результа. M'mayeso osiyanasiyana ozungulira, ma pellets a rPET opangidwa ku Oerlikon Textile R&D Center pogwiritsa ntchito VacuFil adapereka zotsatira zotsimikizika. M'mayeso osiyanasiyana a spin, Oerlikon Textile R&D Center idapeza zotsatira zotsimikizika ndi ma pellets a VacuFil rPET.
Zotsatira za mayeso osiyanasiyana ozungulira awonetsa kuti ukadaulo watsopano wa VacuFil ndiwothandiza kwambiri ndipo umapanga pPET yapamwamba kwambiri, yofananira ndi zida za virgin.
Ngati VacuFil ikuphatikizidwa ndi BB Engineering's rPET yogwirizana ndi VarioFil* R+ compact spinning system (kapena makina ena ozungulira a rPET), gawo la granulation litha kusiyidwa.Chotsaliracho chimabwezeretsedwanso m'njira imodzi yopanda msoko ndipo nthawi yomweyo chimapota - apamwamba kwambiri chifukwa cha kuwongolera kosungunuka bwino.[Anm.: Den folgenden, englischen Part hat der Kunde so abgesegnet.Bitte nicht verändern.] Eco Spindles, kasitomala wa BB Engineering ku Sri Lanka, ali ndi chidaliro cha makina ozungulira a VarioFil R+ ndi VacuFil extrusion kuti akuika ndalama mu machitidwe ena a rPET VarioFil.Dr. Anush Amarasinghe, Woyang'anira Mtsogoleri wa Eco Spindles, amapanga POY kuchokera ku flake material ya botolo, akufotokoza kuti: "Makasitomala athu akusowa kwambiri ulusi wopangidwanso ndipo tikufuna kukwaniritsa zofunikira ndi zosowa zawo.Pachifukwa ichi, tikukulitsa kuchuluka kwazinthu zathu "Kukwaniritsa zomwe tikufuna ndi gawo lofunikira kwa ife.Kubwezeretsanso mabotolo akadali msika wamba ku Sri Lanka ndipo tatsimikiza mtima kusunga miyezo yathu yapamwamba kwambiri.Tili ndi zofunikira zapadera ndipo tikufuna wothandizana nawo wapamwamba pantchitoyi.Zaka zingapo zapitazo tinaganiza zogula makina ozungulira a BBE VarioFil R+ kuti tithe kupanga POY kuchokera ku flakes botolo.Tinkafuna kuyesa chomera choyamba - komanso chifukwa gawo la botolo lomwe linasonkhanitsidwa pamphepete mwa nyanja linali zovuta zoyambira.Komabe, mayankho abwino kwambiri amakasitomala Ndipo kuti zinthu zathu ndizomwe zimapangitsa kuti pakhale ndalama zambiri.Tidaganiza zogula zambiri zapansi pa mzere wa VarioFil R+ ndi VacuFil recirculation system.Chinthu chabwino ndi chakuti ndondomeko yonseyi ikupitirirabe.Titha kupanga rPET yosungunuka kwambiri yokhala ndi viscosity yokhazikika, NDIPO imazungulira molunjika mu ulusi wapamwamba kwambiri. ”
Kwa Eco Spindles, iyi ndi njira yosinthira ya VarioFil R+ yosinthika yokhala ndi makina owongolera owongolera a VacuFil.Zapangidwa kuti zipangidwe pogwiritsa ntchito ma flakes a mabotolo obwezerezedwanso, tchipisi tobwezerezedwanso ndi tchipisi ta namwali.Kumbali imodzi, izi ndizotheka chifukwa chowumitsa ndi choyenera tchipisi ndi nkhuni.Komano, ma vacuum extruder amatha kuyendetsedwa ndi vacuum kapena opanda vacuum motero amatha kusungunula katundu wa namwali. Zomwe zapezedwa kuchokera ku > 20,000 zogulitsa mayunitsi zakhudza kapangidwe ka extruder. Zomwe zapezedwa kuchokera ku > 20,000 zogulitsa mayunitsi zakhudza kapangidwe ka extruder.Zomwe zidapezeka pambuyo pogulitsa mayunitsi opitilira 20,000 zidakhudza mapangidwe a extruder.Zomwe zidapezeka pambuyo pogulitsa mayunitsi opitilira 20,000 zidakhudza mapangidwe a extruder.Chifukwa cha kusungunuka kwake pang'onopang'ono, BBE extruder imapanga maziko a kusungunuka kofanana komwe kumakwaniritsa zofunikira za mphero zopota.Single screw teknoloji imapereka kudalirika kofunikira pakukonza.Pomaliza, machitidwe apadera a dosing a zigawo zingapo amaperekanso kusinthasintha kwa opanga: zowonjezera ziwiri zitha kuwonjezeredwa kusungunuka nthawi imodzi, kapena mayunitsi a dosing angagwiritsidwe ntchito kuti asinthe mtundu mwachangu.VarioFil imakonzedwa ndi maudindo a 6, ili ndi mphamvu zokwana 150 kg / h ndipo imapereka zinthu zambiri zomaliza zomwe zimakhala ndi mapeto a 50 mpaka 150 den (DTY) ndi DPF kuchokera ku 0.7 mpaka 4.0 dpf.Ndi zoikamo zina VarioFil R+ chimakwirira 20-600 den POY kapena 30-500 den FDY ndi recycled PET.*
Chifukwa chake, VarioFil si makina ozungulira padziko lonse lapansi ogwiritsira ntchito zosiyanasiyana, komanso amakwaniritsa kufunikira kwakukula kwa ulusi wa PET wopangidwanso.Kaya opanga mafashoni, opanga zovala zamasewera ndi mipando kapena opanga magalimoto, otsogola opanga nsalu ndi makampani akuyang'ana kwambiri zinthu zokhazikika komanso zopangidwa kuchokera kuzinthu zobwezerezedwanso.Lero adziwitsa ogulitsa ulusi wawo, fiber ndi nonwovens kuti asintha kuchoka pa virgin polyester kupita ku polyester yobwezeretsanso - nthawi zina mpaka 100% - kuti apange nsalu zawo posachedwa.
