Vim li cas 1100 Aluminium Ntawv Nyiaj Siv Rau Cov Tsev
Cov ntawv ci vov tsev ua peb txoj haujlwm ib zaug: nws cuam tshuam cov cua sov, nws ua raws li cov dej tsis muaj dej thiab vapor barrier, thiab nws tiv thaiv cov qauv hauv qab los ntawm corrosion. Qib 1100 txhuas ntawv ci, nrog rau cov ntsiab lus txhuas yam tsawg kawg nkaus ntawm 99.0%, yog ib qho kev xaiv rau tag nrho peb vim hais tias nws ua ke siab ductility ntawm nyias gauges nrog zoo corrosion kuj, siab reflectivity thiab tsis tshua muaj hnyav.
Vim tias cov ntawv ci tau muab los ntawm 0.014 hli mus rau 0.03 hli tuab thiab los ntawm 20 hli mus rau 1600 hli dav, nws tuaj yeem laminated rau bitumen membranes, bonded rau ntxhia wool, rigid foam thiab polyurethane boards, los yog ntsia raws li ib tug standalone reflective ntsej muag. Low density keeps the dead load on the roof structure small, which reduces handling effort and structural cost compared with heavier sheet materials.
Reflective Performance thiab Thermal Behavior
Cov ntaub ntawv txhuas huv si muaj kev cuam tshuam txog li 96% ntawm qhov xwm txheej radiant tshav kub, uas yog vim li cas cov ntawv ci tig rau ntawm lub ru tsev uas pom muaj zog hnub ci. Los ntawm kev xav txog hluav taws xob ua ntej nws nqus los ntawm lub ru tsev lawj, cov ntawv ci txo qhov kub thiab txias ntawm cov rwb thaiv tsev los ua ke thiab txo cov cua sov uas nkag mus rau sab hauv, txiav cov cua txias ntawm huab cua- cov tsev txias.
Kev ua tau zoo tiag tiag nyob ntawm kev teeb tsa, tsis yog ntawm cov khoom siv xwb. Reflectivity ntog thaum lub npoo yog plua plav lossis oxidised, thiab cov ntawv ci uas ntsib qhov chaw huab cua ua tau txawv ntawm ib qho sib txuas ncaj qha mus rau lub substrate. Solar reflectance yog ntsuas nrog cov kev piav qhia hauv ASTM C1549 thiab muab txhais ua Solar Reflectance Index siv ASTM E1980. Emissivity thiab qhov tuab ntawm qhov chaw nyob hauv huab cua txiav txim siab ntau npaum li cas ntawm lub zog xav tau tawm ntawm lub rooj sib txoos, yog li cov ntawv ci ntsej muag feem ntau raug kho raws li lub ntsiab lus ntawm kev rwb thaiv tsev tiav - nce es tsis yog txheej rwb thaiv tsev ntawm nws tus kheej.

Thickness yog tuav nyob rau hauv ntxiv los yog rho tawm 3% ntawm nominal thiab dav nyob rau hauv ntxiv los yog rho tawm 1 hli, thiaj li hais tias sib tshooj thiab sealing cwj pwm nyob twj ywm kwv yees thaum lub installation. Kev sib xyaw ua raws li EN 573-3, GB / T 3190 lossis cov ntawv sau npe sib txuas rau qib 1100. Qhov ntev thiab cov khoom yuav tsum tau txiav txim siab rau EN 546 rau aluminium ntawv ci, EN 485-2 thiab ISO 6361-2 rau daim ntawv thiab sawb, ASTM GB / 10 GBT 1 thiab phaj 3880.2 ib. Vim tias cov ntawv ci vov tsev feem ntau raug ntsia sab nraud, cov khoom lag luam kuj tau teev tseg kom ua tau raws li kev txwv ntawm cov khoom phom sij xws li txhuas thiab cadmium, thiab cov hlau nws tus kheej tuaj yeem rov ua dua thaum kawg ntawm lub neej.
Tempers thiab Mechanical Properties
| Kub | Tensile zog, MPa | Yield zog, MPa | Elongation,% |
|---|---|---|---|
| O | 88 | 29 | 32 |
| H24 | 130 | 110 | 3.9 |
| H26 | 150 | 130 | 2.8 |
Annealed O foil muaj qhov siab tshaj plaws elongation thiab yog siv qhov twg lub ntsej muag yuav tsum ncab tshaj qhov tsis sib xws ntawm cov substrates, lapped nyob ib ncig ntawm fixings thiab ua raws li cov decks profiled tsis muaj tearing. H24 thiab H26 yog strain- hardened tempers: lawv muaj zog thiab khov kho, tiv thaiv kev puas tsuaj thiab tuav ib tug flatter nto, tab sis lawv tsim deb tsawg ua ntej lawv tawg. Cov txiaj ntsig saum toj no yog ib qho piv txwv ib qho - cov ntsiab lus rau qib thiab yuav tsum tau kuaj xyuas raws li kev tswj hwm tshwj xeeb rau kev txiav txim siab kub thiab ntsuas.
Txheej zoo thiab ru tsev Installation luag hauj lwm
Cov ntawv ci vov tsev feem ntau yog muab nrog lacquer lossis polymer txheej ntawm ib lossis ob lub ntsej muag. Polyester, polyvinylidene fluoride, acrylic thiab ceramic- cov tshuab puv yog xaiv raws li qhov yuav tsum tau muaj UV tiv thaiv, xim ruaj khov thiab kev pabcuam lub neej. Cov txheej yuav tsum nyob twj ywm thiab yuav tsum tsis txhob hlwv, tawg los yog tev, thiab nws cov adhesion yuav tsum muaj sia nyob ntev huab cua tsis muaj fading lossis chalking. Lub hauv paus ntawv ci yuav tsum tsis muaj pinholes, khawb, npuas thiab tawg, tsis muaj roj, oxide nplai los yog corrosion me ntsis ntawm qhov chaw thiab tsis muaj ripples los yog buckles uas yuav ntxiab dej los yog cuam tshuam nrog kev sib txuas.
Nyob rau hauv ib tug ua tiav ru tsev los ua ke, cov ntawv ci ua haujlwm ntau lub luag haujlwm:
Waterproof txheej khoom, shielding tus qauv los nag thiab sawv noo noo.
Reflective rwb thaiv tsev tig, rov qab hnub ci hluav taws xob thiab txo qis sab hauv tsev.
Anti- txheej tiv thaiv corrosion, tiv thaiv lub ru tsev saum npoo los ntawm oxidation, tshwj xeeb tshaj yog nyob rau hauv cov av ntub los yog ntsev- tshuaj tsuag ib puag ncig.
Cov khoom sib xyaw ua ke nrog cov ntxhia wool, ua npuas ncauj lossis polyurethane rwb thaiv tsev los txhim kho kev ua haujlwm thermal tag nrho.
Vapor barrier nrog dej tsawg heev vapor kis tau tus mob, txwv condensation nyob rau hauv lub build-up.
Kho kom zoo nkauj tiav uas muab lub ru tsev ib yam xim hlau los yog xim tsos.
Cov ntawv ci siv nrog cov haujlwm no yuav tsum tau teev tseg ua ke nrog nws cov substrate thiab qhov chaw huab cua, vim tias qhov kev ua tau zoo nyob ntawm tag nrho cov kev sib dhos thiab ua kom lub ntsej muag zoo nkauj tom qab kev teeb tsa.
Cov lus nug nquag
Q: Dab tsi yog 1100 txhuas ntawv ci siv rau ntawm lub ru tsev?
Nws yog siv los ua lub ntsej muag pom kev, txheej dej tsis muaj dej, vapor barrier, tiv thaiv - txheej txheej corrosion thiab zoo nkauj tiav, yog khi rau rwb thaiv tsev boards los yog ntsia raws li nyias daim nyias nyias.
Q: Ntau npaum li cas cov ntawv ci cuam tshuam?
Txhuas huv si qhia txog li 96% ntawm qhov teeb meem radiant tshav kub. Qhov tseeb hauv - kev pabcuam kev ua haujlwm qis dua thaum qhov chaw muaj plua plav lossis oxidised, uas yog vim li cas kev ntsuas kev cuam tshuam rau ASTM C1549 thiab Solar Reflectance Index suav rau ASTM E1980 yog siv rau cov qauv ru tsev.
Q: Yam kev kub ntxhov twg yuav tsum xaiv?
O temper rau siab tshaj plaws formability tshaj uneven substrates, thiab H24 los yog H26 qhov twg ntxiv nruj thiab tsis kam rau tuav puas tsuaj yog xav tau.
Q: Dab tsi thickness thiab dav muaj?
Thickness ntawm 0.014 hli mus rau 0.03 hli thiab dav ntawm 20 hli mus rau 1600 hli, nrog txheej thickness ntawm 7 thiab 10 micrometers ntawm ib los yog ob lub ntsej muag.
Q: Puas yog cov ntawv ci tsim nyog rau cov av noo lossis ntug hiav txwv ru tsev?
Yog lawm. Qhov tsawg kawg nkaus 99.0% txhuas cov ntsiab lus tiv thaiv atmospheric corrosion zoo, thiab cov ntawv ci feem ntau teev meej meej rau siab - av noo thiab ntsev - tshuaj tsuag tej yam kev mob.
Q: Puas yog coated vov tsev ntawv ci tuaj yeem siv dua?
Yog lawm. Cov txhuas yog rov ua dua tshiab thaum lub txheej raug tshem tawm lossis hlawv tawm thaum lub sij hawm remelting, thiab lub hauv paus hlau tuaj yeem rov qab mus rau tib yam khoom ntws.
