Siab zog thiab zoo tsim
Nruam fiber ntau reinforced thermosetting composites yog tsim los ntawm reinforcing iav fibers thiab thermosetting resins uas ua raws li binders thiab hloov loads. Cov iav fibers muaj lub zog tensile siab heev (3450 MPa), thiab lawv cov ntsiab lus, qhov ntev, thiab cov txheej txheem nteg txiav txim siab lub zog ntawm cov khoom txhawb nqa. Lub zog ntawm thermosetting iav fiber reinforced composites tuaj yeem nyob ntawm 30-1000 MPa. Yog li ntawd, peb tsim tus nqi, qhov ntev, thiab kev tso cov iav fibers raws li cov khoom lag luam kev ntxhov siab, ntim ntau lawm, kev tsim khoom, thiab kev them taus.
Tsis muaj Creep
Lub rigidity ntawm nruam fiber reinforced thermosetting composite kev txhawb nqa yog ob zaug ntawm fiber ntau - txhawb nqa nylon txhawb nqa tsim los ntawm ib lub tuam txhab Asmeskas. Txawm tias nyob rau hauv ntev - lub sij hawm loads, lawv tsis deform thiab yuav tsis qaij downwards zoo li hlau cable txhawb siv nyob rau hauv ib co subway systems nyob rau hauv Tuam Tshoj.
Hluav taws kub tsis kam
Qhov ntsuas pa oxygen yog ib txoj hauv kev ntsuas tseem ceeb rau kev ntsuas hluav taws- cov khoom siv hluav taws xob. Cov pa oxygen index yog hais txog qhov hluav taws kub ntawm cov khoom nyob rau hauv qhov siab tshaj plaws oxygen. Nws daim ntawv thov nyob rau hauv engineering yuav tsum tau txiav txim siab raws li combustion siv. Piv txwv li, nyob rau hauv tej yam kev mob ntawm 30 cables, yog hais tias ib tug cable ignition kev huam yuaj tshwm sim, ib tug siab - kub tsub zuj zuj ntawm tshaj 500 degrees Celsius tuaj yeem tsim nyob rau hauv 4 feeb, ua rau cov hluav taws kub hnyiab tau raws txoj kab kev taw qhia. Qhov ntau cables nyob rau hauv ib cheeb tsam densely packed, qhov loj ntawm cov khoom combustible ntau dua. Nrog 30 cables, qhov loj ntawm cov khoom siv hluav taws xob rau ib chav tsev ntev yog 20.5 kg / m. Tam sim no, suav nrog 300 cables, qhov loj ntawm cov khoom siv hluav taws xob rau ib chav tsev ntev yog 158 kg / m. Raws li qhov siab tshaj plaws kev siv hluav taws xob, qhov ntsuas pa oxygen yuav tsum tsis pub tsawg dua 65%. Peb ntseeg tias kev teeb tsa cov pa ntsuas pa ntawm 70% hauv cov khoom siv tiv thaiv hluav taws yog qhov tsim nyog.
Raws li cov kev xav tau ntawm kev siv, cov khoom siv hluav taws xob sib txuas uas peb tau tsim muaj qhov ntsuas pa oxygen ntau dua lossis sib npaug li 70%, ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb ntawm hluav taws kub, tsis muaj pa taws, halogen -dawb, thiab tsis yog - lom. Hluav taws kub tsis kam tshaj qhov "Technical Specifications for Fiberglass Yas Cable Trays for Underground Railways in Taiwan" (oxygen index of 52%), thiab kuj tseem muaj ntau dua li ntawm qee lub tuam txhab Asmeskas cov kev txhawb nqa thermoplastic. Qhov kev ua tau zoo no tsis tsawg dua li cov qauv kev tiv thaiv hluav taws rau cov khoom siv sib xyaw siv hauv cov tsheb ciav hlau tshiab ntawm Hong Kong MTR, tau lees paub los ntawm BS hauv UK.
Corrosion Resistance: Nruam fiber reinforced thermosetting composite cov khoom txhawb nqa yog corrosion resistant, ua tshwj xeeb tshaj yog haum rau siv nyob rau hauv cov av noo, ntsev tsuag, acidic, thiab weakly alkaline ib puag ncig.
Hluav taws xob rwb thaiv tsev: rwb thaiv tsev kev ua tau zoo tuaj yeem hloov kho raws li daim ntawv thov. Hluav taws xob insulating hom: rwb thaiv tsev tiv thaiv ntau dua 1000 GΩ; Antistatic hom: nto kuj tsawg dua 10 GΩ.
Kev siv yooj yim: Cov khoom yog ua ntej- kos rau hauv phab ntsa kom raug thiab ruaj ntseg installation, ua rau kev tsim kho yooj yim heev.
