Lub Tsev Kawm Haujlwm University of Vienna tau tsim ib daim ntawv tshwj xeeb epoxy resin rau cov khoom siv fais fab hauv cov aerospace, lub nkoj tsim thiab tsheb tsim, txawm tias muaj dej cawv rov qab. Qhov no yog tiav los ntawm qhov pom ntawm txhua qhov chaw ntawm lub teeb nrog lub teeb.
Hauv ob peb feeb, cov khoom siv tshiab tuaj yeem hloov tau. Pib, cov khoom yog pob tshab thiab tuaj yeem ua kua lossis pasty; ces, thaum twg ib feem ntawm nws yog illuminated nrog lub teeb kom tsim nyog, tag nrho cov resin pib solidify thiab tshwm tsaus. TU Wien (Vienna Technical University) tau patented tshwj xeeb epoxy cob formulations. Tam sim no, cov kws tshawb fawb tau ntse tiav cov txheej txheem dej no. Qhov no txhais tau hais tias cov epoxy resins tshiab tuaj yeem siv rau cov dej num uas tau yooj yim rau kev siv rau hnub, xws li txhaws dej ntws hauv cov choj los yog dej, lossis kho cov kav dej thaum lub sijhawm ua haujlwm.
Ua ib qho tshiab, nov qauv tshwj xeeb no siv tau nrog carbon fiber thiab carbon fiber mats. Muaj ntau ntau txoj kev rau cov kev siv hauv kev tsav dav hlau, cov cua tshuab, kev tsim khoom lossis kev lag luam tsheb - nyob rau txhua cheeb tsam uas muaj kev sib tw ua tau zoo thiab tsim qauv tsim.
Epoxy resins yog cov ntaub ntawv siv los siv rau hauv ntau lub hom phiaj, xws li tshuab hluav taws xob hauv hluav taws xob los yog cov khoom siv kho txhua yam. Ib pab neeg coj los ntawm Professor Robert Liska (TU Wien Lub Koom Haum Uas Ua Haujlwm Chemistry) tsim cov khoom ntxiv ntxiv rau hom epoxy resins los kho lawv lub zog thiab ua tau cov phiaj txhim kho los ntawm laub cov nyees khawm.
"Peb tab tom tsim ib qho chaw tshwj xeeb uas lub teeb yuav ua rau muaj tshuaj lom neeg," piav qhia txog Robert Liska. "Qhov no tej zaum yuav muaj lub teeb ci ntsa iab pom, tab sis peb tseem muaj cov txuas uas tsuas tawm lub teeb rau ultraviolet lub teeb."
Ntawm qhov chaw uas lub teeb ci ntsa iab, cov tshuaj tiv thaiv tau pib tso cua sov. Cov cua kub no kis tau mus rau lwm qhov thiab pib ua ib qho tshuaj khib nyiab kom txog thaum uas tag nrho cov tshuaj kho tau zoo lawm.
"Lub tswv yim tseem ceeb ntawm txoj kev mus kom ze no yog tias tsis muaj qhov yuav tsum ua kom pom tag nrho cov duab xws li lwm yam khoom siv luam yeeb," Liska piav qhia. "Nws yog qhov txaus kom taws ntu ib feem ntawm cov ntxaib. Tus so yuav kho tau txawm tias nyob hauv qhov tob ntawm cov kab tsaus nti uas koj xav ua. "
Muaj sector paj
Cov tuam txhab sib koom tes los ntawm kev lag luam tau nug seb qhov txheej txheem no tseem tuaj yeem nqa tawm ntawm cov "tsaus nti" lossis cov fibers, vim nws tus kheej kho epoxy resins yog ib qho tseem ceeb rau qee yam ntawm cov kev siv ntau nyuaj.
"Nyob rau ntawm qhov chaw, lub tswv yim no tawm tsam tag nrho cov kwv yees," Liska hais. "Lub qhov tob tob ntawm cov khoom siv uas kis tau yooj yim heev vim tias nws yog ib qho ua rau cov kua carbon fiber ntau txaus siab." Tu Wien txoj kev sim tseem qhia txog txoj kev ua haujlwm.
Txuj siv dej ntws tawm los kuj tseem muaj kev cuam tshuam nrog kev tshawb xav.
"Peb pib xav tias nws yeej ua tsis tau. Cov neeg yuav xav tau cov dej kom ntxhe li nrog cov khoom ntawm lub pob cawv thiab tshem tawm cov cua sov uas xav tau los tswj cov tshuaj tiv thaiv. "
Txawm li cas los xij, qhov teebmeem ntawm qhov teebmeem ntawm tus kheej curing tseem tuaj yeem raug ua tiav hauv qab dej.
"Yog vim li cas tseem ceeb ua qhov no yog tias tshuaj lom neeg yuav ua rau dej npau," piav txog Robert Liska. "Tom qab ntawd, nyias ib txheej ntawm cov dej tsis muaj dej khov yog tsim los ntawm cov tawv nqaij tawv thiab cov dej nyob ib puag ncig."
Cov kws tshawb nrhiav yog nrhiav cov neeg siv ntau dua hauv kev lag luam los tshawb txog qhov tseeb ntawm qhov kev cob qhia no. Ntxiv nrog rau daim ntawv thov fiberglass thiab carbon fiber reinforced composites hauv aerospace, nkoj tsim thiab tsheb tsim, kho vaj tse yog thaj chaw tshwj xeeb. Piv txwv, ib tus neeg siv tau tuaj yeem ua kom tawg rau hauv ib lub tsev uas ua dej hauv cov dej uas muaj khov khov thiab tom qab ntawd kho lawv nrog lub teeb taws. Kev tu ntawm lub raj xa dej yog lwm txoj hauj lwm uas feem ntau nyuaj rau kev siv - nws yog ib qho tsim nyog los siv cov tshiab reins ntawm no.
"Muaj ntau ntau txoj hauv kev, thiab peb cia siab tias yuav muaj qee yam nthuav tswv yim tshiab," hais tias Robert Liska.
