"Mukamamanga, abwera" atha kukhala mawu aku Hollywood, koma amafotokozanso njira yopititsira patsogolo yomwe makampani opanga ma composite nthawi zina amagwiritsa ntchito - kuyambitsa zatsopano zotsogola ndikuyembekeza kuti msika udzasintha pakapita nthawi. Sinthani ndikuvomereza. Tekinoloje ya Acell's sheet molding compound (SMC) ndi imodzi mwazinthu zatsopano. Zovomerezeka padziko lonse lapansi mu 2008 ndipo zidayambitsidwa ku US mu 2010, izi zimapereka kuphatikiza kwazinthu ndi njira zopangira masangweji apamwamba kwambiri. Mtengo wa zida zazikulu za mapanelo ndi wotsika kwambiri kuposa kuumba kwanthawi zonse.
Woyambitsa zatsopanozi ndi gulu laukadaulo waku Italy la Acell (Milan, Italy), lomwe lakhala likupanga thovu lotseguka la cell phenolic pazaka 25 zomanga zosagwira moto. Acell ankafuna kupeza msika wokulirapo wazogulitsa thovu ndipo adapanga njira yogwiritsira ntchito thovu kuphatikiza ndi SMC kupanga bwino zitseko ndi zinthu zina zamsika pamsika womanga. Wothandizana naye waukadaulo Acell Italpresse SpA (Bagnatica, Italy ndi Punta Gorda, Florida) adapanga ndikumanga mzere wathunthu wopanga mapanelo ophatikizika molingana ndi magawo omwe adanenedwa. "Timakhulupirira njira yathu yamabizinesi yopangira njira ndi zinthu zomwe zingagwiritsidwe ntchito padziko lonse lapansi," atero a Acell Chief Commerce Officer Michael Free.
Mwina akulondola. Izi zinapangitsa chidwi kwambiri pamakampani. M'malo mwake, Ashland Performance Materials (Columbus, Ohio) wapanga mgwirizano wogwirizana ndi Acell kulimbikitsa ukadaulo uwu ku North America. Njira ya Acell idapatsidwanso Mphotho ya 2011 Composites Excellence Award (ACE) ndi American Composite Manufacturers Association. (ACMA, Arlington, Virginia) Gulu la Njira Yatsopano.
The latsopano akamaumba ndondomeko ndi crystallization wa kuchuluka kwa kafukufuku ndi chitukuko cha mapanelo masangweji. Dave Ortmyer, COO wa Italpresse USA, adalongosola kuti mapangidwe a zitseko omwe alipo kale amapangidwa kudzera muzitsulo zambiri komanso zogwira ntchito zomwe zimaphatikizapo kupanga chimango chamkati, kupukuta khungu la SMC, kusonkhanitsa zigawozo, ndipo pamapeto pake, thovu la polyurethane limatsanulidwa mkati. kwa kutchinjiriza kwamafuta. Mosiyana ndi izi, njira ya Acell imapanga chitseko chofanana ndi sitepe imodzi yokha komanso pamtengo wotsika kwambiri. "Nkhungu yapakhomo ya SMC imatha kuwononga ndalama zokwana $300,000," adatero Ortmyer. "Njira yathu imatha kukupatsirani chitseko chomaliza nthawi imodzi, mtengo wa zida udzakhala $20,000 mpaka $25,000."
Zipangizo zimagwira ntchito yofunika kwambiri. Mosiyana ndi thovu zambiri za phenolic, zomwe zimakhala zofewa, zofewa komanso zosalimba (monga chithovu chobiriwira chamaluwa chomwe chimagwiritsidwa ntchito pokonza maluwa), Acell foam ndi kuphatikiza kwazinthu zomwe zimapangidwira kupanga thovu lolimba kwambiri. m3 (5 mpaka 50 lb/ft3). Chithovuchi chimakhala ndi mphamvu zoteteza kutentha, moto, utsi ndi kawopsedwe (FST) kukana, komanso kutulutsa mawu. Imapezekanso m'maselo osiyanasiyana, Free adatero. SMC yodzaza ndi magalasi yomwe imagwiritsidwa ntchito pamapulogalamu apakhomo amapangidwa ndi Acell, adatero. Chifukwa SMC imakonda kutulutsa mpweya pakuwumba, Ortmeier akuti, thovulo limakhala ngati zinthu zopumira, zomwe zimalola mpweya kuthawa nkhungu kudzera mumabowo.
Komabe, vuto lalikulu ndi kupezeka. Ortmeier adati othandizana nawo akuyembekeza kupereka zida zotsika mtengo kwa opanga ang'onoang'ono kapena omwe amapanga zinthu zingapo pakanthawi kochepa. M'mapangidwe amtundu wa SMC, zidazo zimakhala zazikulu komanso zokwera mtengo, akuti, osati chifukwa chakuti zigawozo ndi zazikulu, komanso chifukwa zimayenera kupirira kuwonongeka chifukwa cha kusuntha ndi kutuluka kwa "malipiro" ambiri a SMC. mu nkhungu. . pansi kwenikweni mkulu ntchito kuthamanga.
Chifukwa chithovu cha Acell chokhazikika chimakhalabe "chopunduka" (chopunduka) pansi pa kukanikiza, kukanikiza kwanthawi zonse kumaphwanya kwathunthu, kotero kukakamiza kuumba kuyenera kukhala kochepa. Chifukwa chake, njira ya Acell imangogwiritsa ntchito kagawo kakang'ono ka SMC pakhungu. Sichisuntha kapena kuyenda cham'mbali, kotero palibe chiwopsezo cha kuvala pamwamba pa chida. M'malo mwake, utomoni wa SMC umayenda mozungulira z-njira - njirayo idapangidwa kuti ipereke kutentha kokwanira mu nkhungu kuti isungunuke matrix a SMC, zomwe zimapangitsa kuti utomoni ulowe m'maselo a thovu oyandikana nawo pomwe umaphwanyika pang'ono.
"Panthawi yakuumba, chipolopolo cha SMC chimakhala chokhazikika pamakina ndi mankhwala," akufotokoza Frey, ndipo akuti "kuwonongeka kwa zipolopolo sikutheka." chida champhamvu kwambiri. Mtengo wa zoyika ziwiri zoonda (pamwamba ndi pansi) zokhala ndi tsatanetsatane wofunikira ndi kachigawo kakang'ono chabe ka mtengo wofunikira kupanga chida chachitsulo kapena chopangidwa ndi aluminiyamu cha SMC. Zotsatira zake, abwenzi akuti, ndi njira yotsika mtengo yopereka zochitika zambiri pamtengo wodziwika bwino.
Komabe, kukwanitsa ndi kukwanitsa sikulepheretsa kusinthika. Mayesero angapo adachitika momwe zida zoluka zidaphatikizidwa mu laminate. Iwo amangomangidwa mu gawo lapakati, kuwonjezera mphamvu yopindika ya mapanelo. Malinga ndi Free, nsalu zolukidwa za aramid, zisa zachitsulo komanso zoyikapo pultrud zitha kuphatikizidwa mu mapanelo a masangweji ndikukanikizidwa pakukonza kukana kuphulika, kuteteza kuba ndi zina zambiri. "Tikufuna kuti opanga amvetsetse kuti njirayi ndi yosinthika komanso yosinthika," adatero. "Imatha kupanga mapanelo okhuthala kapena owonda pamtengo wotsika popanda kukonza zina monga gluing kapena kumangirira."
Chomera chopangira, chopangidwa ndi Italpresse makamaka cha Acell, chimakhala ndi makina osindikizira a matani 120 okhala ndi mbale zotenthetsera kuti aike nkhungu zamapanelo. Chipinda chapansi chimapangidwa kuti chiziyenda mkati ndi kunja kwa makina osindikizira, ndipo Ortmeier akuti ndizotheka kuwonjezera mbale yachiwiri yotenthetsera pansi mbali ina ya makinawo kuti ikhazikike pa nkhungu imodzi pamene ina ili mu makina osindikizira pogwiritsa ntchito Layup. siteshoni. Ma slabs ndi 2.6m / 8.5ft x 1.3m/4.2ft pazogwiritsa ntchito "zokhazikika" monga zitseko zokongoletsa, koma masilabu amatha kupangidwa kuti agwirizane ndi ma projekiti apadera. Ndizofunikira kudziwa kuti ndizothekanso kusintha makina osindikizira omwe alipo kuti agwirizane ndi njira ya Acell, bola ngati kukakamiza kumatha kuwongoleredwa (kudzera poyimitsa kufa) kuti mupewe kuponderezana.
Ziumba zimapangidwa payekhapayekha pagawo lililonse la polojekiti ndipo zitha kupangidwa ndi njira zachikhalidwe zoponya. Kuti mupeze mawonekedwe apamwamba a nkhungu omwe amatsanzira zinthu zachilengedwe monga matabwa kapena mwala, mapanelo a fiberglass / polyester amayikidwa mwachindunji pazinthu zomwe mungasankhe kuti apange mapangidwe apamwamba a zida zapamwamba ndi zapansi. Zitsanzo ziwiri zazikuluzikulu zimatumizidwa ku maziko, kumene zida zimaponyedwa muzitsulo za aluminium-nickel. Chida chochepa kwambiri chimatenthetsa mwachangu ndipo chimatha kukwezedwa ndikusunthidwa ndi ogwiritsa ntchito awiri chikakhala chopanda ntchito. Zida zina zilipo, koma njira zopangira zida zimapanga zida pamtengo wokwanira ndipo nthawi zambiri 0.75 ″ mpaka 1 ″ (20 mpaka 25 mm) wandiweyani.
Pakupanga, nkhunguyo imakonzedwa molingana ndi zomwe zimafunidwa pamwamba pa gululo. Mitundu yosiyanasiyana ya zokutira ndi zomaliza zilipo, Kufotokozera Kwaulere, kuphatikiza zokutira za ufa (PiMC), ufa wothira mafuta womwe umasungunuka ndikuchitapo kanthu ndi SMC kupanga zokutira za UV komanso zosagwirizana ndi zokanda. Mtundu wapamwamba wa gulu. Zosankha zina zimaphatikizapo kuthira mchenga wamitundu kapena wachilengedwe pamwamba pa nkhungu kuti ufanizire mwala, kapena kugwiritsa ntchito chophimba chosindikizidwa chomwe chitha kuwonjezera mawonekedwe ndi mawonekedwe. Kenako, ulusi pamwamba amaikidwa pa nkhungu, ndiye wosanjikiza magalasi odzazidwa SMC kudula mu mauna mawonekedwe ndi anagona pansi pa nkhungu okonzeka.
Chidutswa cha 1 ″/26mm wandiweyani wa Acell foam (wodulidwanso kuti ukhale mauna) kenako adayikidwa pamwamba pa SMC. Chigawo chachiwiri cha SMC chimagwiritsidwa ntchito ku thovu limodzi ndi filimu yachiwiri kuti ithandizire kutulutsidwa kwa magawo ndikupereka njira yosinthira zosinthika zomwe zimatulutsidwa ndi SMC. Pansi kufa, amene anaikidwa pamwamba pa mkangano platen, ndiye umakaniko kapena pamanja kudyetsedwa mu atolankhani kumene ndondomeko kutentha 130 ° C kuti 150 ° C (266 ° F kuti 302 ° F) anafika. Tsitsani nkhungu yapamwamba pamtengowo, ndikusiya kagawo kakang'ono ka mpweya pakati pa zisankho, ndikusindikiza gawo lapakati ndi mphamvu ya 5 kg / cm2 (71 psi) kwa mphindi zisanu kuti mupange gulu lolimba monga gawo 6. kupondaponda, mikanda imatuluka ndipo gawolo limachotsedwa.
Kuti apange chitseko chofanana ndi chitseko, ndondomekoyi idasinthidwa ndikuwonjezera chimango chamatabwa cha sangweji m'mphepete mwa chidutswa (sitepe 3) ndikuyika thovu mkati mwa chimango. Mitengo yam'mphepete imalola kuti zitseko zidulidwe m'miyeso yolondola ndikuyika mahinji ndi zokokera mosavuta, akufotokoza Fritsch.
Ngakhale zitseko zambiri zamagulu ambiri tsopano zimapangidwa ku Asia, Ortmayer akuti njira ya Acell "imaloleza kupanga 'komweko' pamtunda chifukwa chotsika mtengo. Ndi njira yopangira ntchito zopangira zinthu pamtengo wokwanira. Pakalipano pali malayisensi asanu ndi awiri ku Ulaya omwe amagwiritsa ntchito njira ya Acell kupanga zitseko ndi zinthu zina zamagulu, ndipo chidwi ku US chakula mofulumira kuyambira pamene adalandira mphoto ya ACMA mu 2011, akutero Free, omwe akuyembekeza kuwona zambiri m'zigawo zomanga zakunja. Nthawi zambiri amagwiritsidwa ntchito, mwachitsanzo, ngati mapanelo otchinga (onani chithunzi), njirayi ndi yabwino kwambiri pakutchinjiriza kwamafuta, kukana kwa UV komanso kukana kwamphamvu.
Ubwino wina ndikuti mapanelo a Acell ndi 100% obwezerezedwanso: mpaka 20% yazinthu zobwezerezedwanso zimagwiritsidwanso ntchito popanga thovu. "Tapanga njira yopangira ndalama komanso yobiriwira ya SMC," adatero Free. Mike Wallenhorst adati mgwirizano wanzeru ndi Ashland ukuyembekezeka kupangitsa kuti ukadaulo udziwike kwambiri. Director of Product Management ku Ashland. "Ndi tekinoloje yochititsa chidwi yomwe imayenera anthu ambiri."
US ikuwoneka kuti ndiyokonzeka kuyika ndalama zambiri pazomangamanga. Kodi makampani opanga ma kompositi angachite izi?
Mapanelo ophatikizika oletsa moto amapereka mawonekedwe, osawotcha mpweya komanso mawonekedwe owoneka bwino ku nyumba zomwe zikuchita upainiya ku Dubai.
Lingaliro lomanga modular latengera zomanga zamagulu ambiri, ndikupereka njira zingapo zotsika mtengo zopangira nyumba zamitundu yonse ya omanga.
