"Yog tias koj tsim nws, lawv yuav tuaj" tej zaum yuav yog Hollywood catchphrase, tab sis nws kuj piav qhia txog kev nce qib ntawm kev lag luam kev lag luam qee zaum ua haujlwm - qhia txog kev tsim kho tshiab hauv kev cia siab tias kev lag luam yuav hloov zuj zus mus dhau sijhawm. Kho thiab txais nws. Acell's sheet molding compound (SMC) technology yog ib qho kev tsim kho tshiab. Patented thoob ntiaj teb hauv xyoo 2008 thiab tau tshaj tawm hauv Asmeskas xyoo 2010, cov txheej txheem no muab kev sib xyaw ntawm cov khoom siv thiab cov txheej txheem rau kev ua haujlwm siab kev cai sandwich molding. Cov cuab yeej cuab tam peev ntawm cov panels yog qis dua li cov pa compression molding.
Tus inventor ntawm no innovation yog Italian tshuaj technology pab pawg neeg Acell (Milan, Ltalis), uas tau tsim ib tug tshwj xeeb qhib-cell phenolic ua npuas ncauj core rau hluav taws-resistant vaj tse rau 25 xyoo. Acell xav nrhiav kev lag luam dav dua rau nws cov khoom ua npuas ncauj thiab tsim ib txoj hauv kev siv ua npuas ncauj ua ke nrog SMC kom ua tau zoo tsim cov qhov rooj thiab lwm cov khoom vaj huam sib luag rau lub tsev lag luam. Kev koom tes nrog Acell Italpresse SpA (Bagnatica, Ltalis thiab Punta Gorda, Florida) tsim thiab ua tiav cov kab ntau lawm rau kev tsim cov vaj huam sib luag sib xyaw raws li cov kev txwv tsis pub dhau. "Peb ntseeg peb tus qauv kev lag luam ntawm kev tsim cov txheej txheem thiab cov khoom siv rau kev siv thoob ntiaj teb," said Acell Chief Commercial Officer Michael Free.
Tej zaum nws hais yog lawm. Qhov no ua rau muaj kev txaus siab ntau hauv kev lag luam. Qhov tseeb, Ashland Performance Materials (Columbus, Ohio) tau tsim kev sib koom tes nrog Acell los txhawb cov thev naus laus zis no hauv North America. Cov txheej txheem Acell kuj tau txais 2011 Composites Excellence Award (ACE) los ntawm American Composite Manufacturers Association. (ACMA, Arlington, Virginia) Txheej txheem Innovation qeb.
Cov txheej txheem molding tshiab yog crystallization ntawm ntau qhov kev tshawb fawb thiab kev loj hlob ntawm sandwich panels. Dave Ortmyer, COO ntawm Italpresse USA, piav qhia tias cov qauv tsim qhov rooj uas twb muaj lawm yog tsim los ntawm ntau cov kauj ruam thiab siv zog ua haujlwm uas suav nrog kev tsim cov thav duab puab, laminating SMC daim tawv nqaij, sib sau cov khoom, thiab thaum kawg, polyurethane ua npuas ncauj yog nchuav rau hauv. rau thermal rwb thaiv tsev. Hauv qhov sib piv, Acell cov txheej txheem tsim cov vaj huam sib luag qhov rooj sib npaug hauv ib kauj ruam thiab ntawm tus nqi pib qis dua. "Ib tsoos SMC qhov rooj ntawm daim tawv nqaij tuaj yeem raug nqi txog $ 300,000," Ortmyer tau hais. "Peb cov txheej txheem tuaj yeem muab koj lub qhov rooj tiav hauv ib qho mus, tus nqi ntawm cov cuab yeej yuav yog $ 20,000 txog $ 25,000."
Cov ntaub ntawv ua lub luag haujlwm tseem ceeb hauv cov txheej txheem. Tsis zoo li feem ntau cov phenolic foams, uas yog mos, nkig thiab tsis yooj yim (xws li cov paj ntoo ntsuab siv rau kev npaj paj), Acell ua npuas ncauj yog ib qho kev sib xyaw ntawm cov khoom xyaw tsim kom muaj zog ua npuas ncauj. m3 (5-50 lb/ft3). Cov npuas dej muaj thermal rwb thaiv tsev, hluav taws kub, pa taws thiab toxicity (FST) tsis kam, thiab suab-absorbing zog. Nws tseem muaj nyob rau hauv ntau qhov ntau thiab tsawg ntawm tes, Free said. Lub iav puv SMC siv nyob rau hauv lub qhov rooj panels yog tsim los ntawm Acell, nws hais tias. Vim tias SMC nquag tawm hauv lub sijhawm molding, Ortmeier hais tias, ua npuas ncauj ua cov khoom ua pa, tso pa tawm ntawm cov pwm los ntawm qhov.
Txawm li cas los xij, qhov teeb meem tseem ceeb yog kev nkag mus tau. Ortmeier tau hais tias cov neeg koom tes vam tias yuav muab cov cuab yeej siv tau zoo rau cov neeg tsim khoom me lossis cov uas tsim ntau yam khoom ntawm kev ceeb toom luv luv. Nyob rau hauv ib txwm SMC compression molding, cov cuab yeej yog loj thiab kim, nws hais tias, tsis tsuas yog vim hais tias cov khoom yog loj, tab sis kuj vim hais tias lawv yuav tsum tau tiv taus qhov hnav thiab tsim kua muag los ntawm kev txav thiab ntws ntawm ntau SMC "them" lined. hauv pwm. . nyob rau hauv qhov tsim nyog siv siab.
Vim tias cov txheej txheem ntau ntawm Acell ua npuas ncauj tseem "nkim" (deformable) nyob rau hauv siab, ib txwm nias siab yuav ua rau nws tag nrho, yog li molding siab yuav tsum qis. Yog li ntawd, cov txheej txheem Acell tsuas yog siv txheej nyias ntawm SMC ntawm daim tawv nqaij. Nws tsis txav los yog ntws mus rau sab, yog li tsis muaj kev pheej hmoo ntawm kev hnav ntawm cov cuab yeej nto. Qhov tseeb, SMC resin tsuas yog ntws hauv z-kev taw qhia - cov txheej txheem yog tsim los muab cov cua sov txaus hauv pwm kom liquefy SMC matrix, ua rau qee cov resin nkag mus rau hauv cov ua npuas ncauj uas nyob ib sab vim nws tawg me ntsis hauv siab.
Frey piav qhia tias "Thaum lub voj voog molding, SMC plhaub yog qhov tseem ceeb ntawm cov tshuab thiab cov tshuaj kho hauv cov npuas dej," Frey piav qhia, thiab hais tias "plhaub delamination yog tsis yooj yim sua." Lwm yam cuab yeej muaj zog heev. Tus nqi ntawm ob lub cam khwb cia nyias nyias (sab saum toj thiab hauv qab) nrog rau qhov yuav tsum tau nthuav dav tsuas yog ib feem ntawm tus nqi tsim nyog los tsim cov hlau lossis machined aluminium SMC cuab yeej. Qhov tshwm sim, cov neeg koom tes hais tias, yog tus txheej txheem pheej yig uas muab ntau yam kev hloov pauv ntawm tus nqi nominal ntawm peev.
Txawm li cas los xij, kev them taus thiab kev them taus tsis txiav txim siab hloov pauv. Ntau qhov kev ntsuam xyuas tau ua nyob rau hauv uas cov ntaub ntawv woven tau suav nrog hauv laminate. Lawv tsuas yog ua rau hauv cov txheej txheem nruab nrab, ua kom lub zog khoov ntawm cov panels. Raws li Dawb, woven aramid fabrics, hlau honeycombs thiab txawm pultruded inserts tuaj yeem muab tso rau hauv cov xuab zeb panels thiab nias thaum lub sij hawm ua rau ntxiv blast tsis kam, tiv thaiv tub sab thiab ntau dua. "Peb xav kom cov neeg tsim khoom nkag siab tias cov txheej txheem no hloov tau yooj yim thiab hloov tau," nws piav qhia. "Nws tuaj yeem tsim cov vaj huam sib luag tuab lossis nyias nyias ntawm tus nqi qis yam tsis muaj kev ua haujlwm ntxiv xws li gluing lossis fastening."
Cov txheej txheem cog, tsim los ntawm Italpresse tshwj xeeb rau Acell, muaj 120 tonne downstroke xovxwm nrog rhuab daim hlau los tso cov pwm rau cov panels. Lub platen hauv qab yog tsim los txav mus rau hauv thiab tawm ntawm cov xovxwm txiav, thiab Ortmeier hais tias nws muaj peev xwm ntxiv ob lub rhuab hauv qab platen rau sab nraud ntawm lub tshuab kom nteg rau ntawm ib lub pwm thaum lwm tus nyob hauv xovxwm siv Layup. chaw nres tsheb. Slabs yog 2.6m / 8.5ft x 1.3m / 4.2ft rau "tus qauv" daim ntawv thov xws li cov qhov rooj zoo nkauj, tab sis cov slabs tuaj yeem ua kev cai ua kom haum rau cov haujlwm tshwj xeeb. Nws yog ib qho tsim nyog sau cia tias nws tseem tuaj yeem hloov kho cov teeb tsa xovxwm uas twb muaj lawm kom haum rau cov txheej txheem Acell, yog tias lub siab tuaj yeem tswj tau (ntawm qhov tuag nres) kom tsis txhob muaj kev sib tsoo.
Moulds yog tsim los ntawm tus kheej rau txhua qhov project vaj huam sib luag thiab tuaj yeem ua los ntawm cov txheej txheem casting. Yuav kom tau txais lub siab txhais pwm nto uas ua raws li cov khoom siv ntuj tsim xws li ntoo lossis pob zeb, fiberglass / polyester panels tau tso ncaj qha rau ntawm cov khoom xaiv los tsim cov qauv tswv rau cov cuab yeej sab saud thiab qis. Ob tug tswv qauv raug xa mus rau lub foundry, qhov twg cov cuab yeej raug cam khwb cia nyob rau hauv aluminium-nickel alloy. Cov cuab yeej nyias nyias ua kom sov sai thiab tuaj yeem nqa thiab txav los ntawm ob tus neeg ua haujlwm thaum tsis ua haujlwm. Lwm cov kev xaiv cuab yeej muaj, tab sis cov txheej txheem casting tsim cov cuab yeej ntawm tus nqi tsim nyog thiab feem ntau 0.75 "mus rau 1" (20 mus rau 25 mm) tuab.
Thaum lub sij hawm tsim khoom, cov pwm yog npaj raws li qhov xav tau ntawm lub vaj huam sib luag tiav. Muaj ntau yam molding coatings thiab finishes muaj, Dawb piav qhia, nrog rau molding hmoov txheej (PiMC), ib tug dav siv sprayable pigment hmoov uas melts thiab reacts nrog SMC los ua ib tug UV thiab khawb resistant txheej. Vaj huam sib luag nto xim. Lwm cov kev xaiv muaj xws li nchuav cov xim lossis cov xuab zeb ntuj tshaj cov pwm los simulate pob zeb, lossis siv daim ntaub thaiv uas tuaj yeem ntxiv kev ntxhib los mos thiab qauv. Tom ntej no, cov txheej txheem saum npoo yog nteg rau ntawm pwm, tom qab ntawd txheej ntawm cov iav ntim SMC raug txiav rau hauv cov duab mesh thiab muab tso rau hauv cov pwm npaj.
Ib daim ntawm 1 "/ 26mm tuab Acell ua npuas ncauj (tseem txiav rau mesh zoo) ces muab tso rau saum SMC. Cov txheej thib ob ntawm SMC yog siv rau cov npuas dej nrog rau cov yeeb yaj kiab thib ob los pab txhawb kev tso tawm ntawm qhov chaw thiab muab cov raj xa mus rau cov volatiles tawm los ntawm SMC. Cov tuag hauv qab, uas yog muab tso rau saum lub rhuab platen, ces mechanically los yog manually pub rau hauv xovxwm qhov twg ib tug txheej txheem kub ntawm 130 ° C mus rau 150 ° C (266 ° F mus rau 302 ° F). Txo cov pwm sab saum toj mus rau pawg, tawm hauv qhov sib txawv me me ntawm cov pwm, thiab nias cov txheej txheem nruab nrab nrog lub zog ntawm 5 kg / cm2 (71 psi) li ntawm tsib feeb los tsim cov khoom vaj huam sib luag raws li hauv kauj ruam 6. Thaum lub sij hawm lub stamping voj voog, cov hlaws dai tawm thiab ib feem raug tshem tawm.
Txhawm rau tsim ib lub qhov rooj vaj huam sib luag, cov txheej txheem tau hloov kho los ntawm kev ntxiv cov ntoo sandwich nyob ib ncig ntawm lub npoo ntawm daim (kab ruam 3) thiab txhim kho ua npuas ncauj rau hauv tus ncej. Edged ntoo tso cai rau lub qhov rooj txiav kom meej qhov ntev thiab mounting hinges thiab fittings tuaj yeem ntsia tau yooj yim, Fritsch piav qhia.
Thaum lub qhov rooj sib xyaw feem ntau yog tam sim no ua nyob rau hauv Asia, Ortmayer hais tias cov txheej txheem Acell "tso cai 'hauv zos' ntau lawm ntawm thaj av vim nws tus nqi qis. Nws yog ib txoj hauv kev los tsim cov haujlwm tsim khoom ntawm tus nqi tsim nyog. Tam sim no muaj xya daim ntawv tso cai nyob hauv Europe siv cov txheej txheem Acell los ua lub qhov rooj thiab lwm cov khoom vaj huam sib luag, thiab kev txaus siab hauv Teb Chaws Asmeskas tau loj hlob sai heev txij li tau txais ACMA khoom plig xyoo 2011, hais tias Dawb, uas cia siab tias yuav pom ntau ntxiv hauv cov khoom siv sab nraum zoov. Feem ntau siv, piv txwv li, raws li cladding panels (saib daim duab), cov txheej txheem no zoo heev nyob rau hauv cov nqe lus ntawm thermal rwb thaiv tsev, UV kuj thiab cuam tshuam tsis kam.
Lwm qhov zoo dua yog tias Acell panels yog 100% recyclable: mus txog 20% ​​ntawm cov khoom siv rov qab siv dua hauv kev ua npuas dej. "Peb tau tsim kev lag luam thiab ntsuab SMC molding txheej txheem," Dawb hais. Mike Wallenhorst tau hais tias kev sib koom tes nrog Ashland xav tias yuav ua rau cov thev naus laus zis paub ntau dua. Tus Thawj Coj ntawm Kev Tswj Khoom Muag ntawm Ashland. "Nws yog ib qho khoom siv zoo nkauj uas tsim nyog rau cov neeg tuaj saib dav dua."
Teb Chaws Asmeskas zoo li npaj tau nqis peev ntau hauv kev tsim kho vaj tse. Cov kev lag luam puas tuaj yeem daws qhov no?
Hluav taws kub retardant composite panels muab cov qauv, airtightness thiab iconic facades rau pioneering tsev nyob rau hauv Dubai.
Lub tswv yim ntawm lub tsev modular tau coj lub tsev sib xyaw ua ke ntxiv ib kauj ruam ntxiv, muab ntau yam kev daws teeb meem rau vaj tse pheej yig rau txhua hom tsim.
