Composite Technology: Cov kos duab ntawm qhov sib npaug ntawm lub teeb thiab lub zog
Lub hauv paus ntawm cov khoom siv tshiab no yog nyob rau hauv nws "kev txhawb nqa rigidity" kev tsim qauv sib xyaw. Pab neeg technical siv20-30mm ntuj cobblestonesRaws li cov khoom siv hauv paus, ua ntej kho lawv qhov chaw nrog nano- nplai roughening, ces qhwv lawv nrog 0.5mm- tuab basalt fiber mesh, thiab thaum kawg txhaj qis -viscosity epoxy resin rau kho. Cov txheej txheem no txo cov khoom tiav qhov ceev mus rau 1.2g / cm³-tsuas yog 50% ntawm cov pob zeb ntuj qub (cov granite ib txwm muaj qhov ntom ntom ntawm 2.6g / cm³)-thaum tuav lub zog compressive tshaj 80MPa, deb tshaj qhov tsawg kawg nkaus tus qauv rau cov khoom siv cladding (Ntau tshaj 30MPa).
Qhov "bridging effect" ntawm basalt fiber mesh yog qhov tseem ceeb: thaum cov khoom raug cuam tshuam los ntawm sab nraud quab yuam, fiber ntau mesh absorbs lub zog los ntawm deformation, tiv thaiv cov kab nrib pleb los ntawm kev sib kis mus rau hauv lub cobblestone. Epoxy resin, ua yeeb yam zoo li "tsis pom cov kua nplaum," ua rau lub pob zeb lub qhov hws, txhim kho kev ncaj ncees thaum muab cov huab cua tiv thaiv (tom qab 5,000 teev ntawm kev kuaj kev laus UV, xim tuav mus txog 90%). Qhov kev sib xyaw ua ke no tso cai rau lub pob zeb los txo nws qhov hnyav "qhov hnyav" thaum khaws cov khoom zoo nkauj ntawm ntuj textures.
Daim Ntawv Thov Kev Lag Luam: Los ntawm Lab mus rau Landmark
Burj Al Arab lub façade renovation project los ua "nyob showcase" rau cov khoom no. Lub 321-meter- qhov chaw siab tshaj qub yog siv cov pob zeb limestone cladding, nrog rau txhua lub pob zeb hnyav 80kg, tsim kom muaj kev thauj mus los tsis tu ncua ntawm lub tsev qauv thiab tsav cov nqi hoisting. Tom qab hloov mus rau carbon-fiber reinforced cobblestones, txhua daim qhov hnyav poob mus rau 48kg, txo tag nrho facade system qhov hnyav los ntawm 40%.
Cov txiaj ntsig ncaj qha tau pom tseeb: cov khoom siv hoisting tau txo qis los ntawm 25-tuj mus rau 16-tuj chav kawm, ib leeg hoisting efficiency nce 30%, thiab tag nrho cov nqi hoisting rau kev kho dua tshiab tau txo los ntawm $ 1.2 lab. Qhov tseem ceeb tshaj, cov khoom siv hnyav txo qis kev ntxhov siab ntxiv ntawm lub tsev cov qauv tseem ceeb, tshem tawm cov txheej txheem kev txhim kho cov txheej txheem thiab ua kom lub sijhawm siv sijhawm luv dua 15 hnub. Kev lees txais kev kuaj pom tau hais tias cov txheej txheem cladding tshiab tsuas muaj 1/3 qhov kev hloov ntawm cov pob zeb ib txwm nyob hauv qab cua daj cua dub (qib qib 12), nrog kev ruaj ntseg tshaj qhov kev cia siab.
Environmental Certification: Dual Endorsement of Performance and Sustainability
Raws li cov qauv vaj tsev ntsuab tau dhau los ua nruj dua, cov yam ntxwv ib puag ncig ntawm carbon-fiber reinforced cobblestones kuj sawv tawm. Nws tau dhau los ntawm EU EN 13501 Class A1 daim ntawv pov thawj hluav taws kub -tom qab 1 teev ntawm 灼烧 ntawm 800 degree, nws tuav cov txheej txheem kev ncaj ncees tsis muaj melting los yog dripping, ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb hluav taws kub ntawm super siab - nce.
Tshwj xeeb tshaj yog, nws tag nrho -lub neej- voj voog kev ruaj ntseg: basalt fibers thiab epoxy resin nyob rau hauv cov khoom yuav raug muab cais thiab rov siv dua los ntawm cov tshuaj depolymerization, thaum cobblestones tuaj yeem rov- nkag mus rau cov txheej txheem sib xyaw tom qab ntxuav, ua tiav 100% rov qab tus nqi. Qhov no tso cai rau nws kom tau txais 3 qhov qhab nia ntxiv hauv LEED daim ntawv pov thawj lub tsev ntsuab, ua rau nws muaj txiaj ntsig zoo rau eco- cov haujlwm tsim kho tus phooj ywg.
