Q: Dab tsi yog qhov tseem ceeb ntawm kev rwb thaiv tsev ua ke rau galvanized steel ntawv coated coils?
A: Muaj peb lub ntsiab lus tseem ceeb ntawm cov khoom siv rwb thaiv tsev ua ke ntawm kev ua lag luam, haum rau cov xwm txheej sib txawv:
** Kev Lag Luam Kev Lag Luam: ** Coated steel ntawv + EPS (polystyrene ua npuas ncauj): zoo rwb thaiv tsev kev ua tau zoo thiab tus nqi qis tshaj, tab sis tsis zoo hluav taws kub (feem ntau B2 qib, combustible), tsis haum rau cov chaw uas muaj kev tiv thaiv hluav taws kub.
** Kev Ua Haujlwm Zoo Tshaj Plaws: ** Coated steel ntawv + PU / PIR (polyurethane): Kev ua haujlwm zoo thermal rwb thaiv tsev, ua tiav tib lub rwb thaiv tsev zoo nrog cov ntawv nyias nyias, thiab qhov ntsuas hluav taws kub txog li B1 (nplaim- retardant).
**Kev nyab xeeb thiab kev ua raws li kev sib xyaw ua ke:** Cov ntawv hlau coated + pob zeb wool / iav ntaub plaub: Cov hluav taws kub zoo tshaj plaws, cais raws li Chav Kawm A uas tsis yog- cov khoom siv hluav taws xob. Kuj tseem muaj lub suab rwb thaiv tsev zoo heev.
Q: Kuv yuav xaiv li cas ntawm cov kev xaiv sib txawv no?
A: Qhov kev xaiv nyob ntawm koj qhov kev xav tau tshwj xeeb, xav tau qhov sib npaug ntawm kev ua tau zoo, kev nyab xeeb, thiab tus nqi:
Xav txog qhov yuav tsum tau muaj kev nyab xeeb hluav taws: Qhov no yog qhov yuav tsum tau ua. Yog tias qhov project muaj cov cai tswj kev nyab xeeb ntawm hluav taws nruj heev (xws li hauv cov chaw ua haujlwm uas muaj neeg coob), koj yuav tsum xaiv Class A uas tsis yog- cov khoom siv hluav taws xob xws li pob zeb wool. Yog tias tsis muaj cov cai tshwj xeeb, PU lossis EPS tuaj yeem xaiv.
Xav txog kev xav tau kev rwb thaiv tsev: Rau cov kev xav tau siab ntawm kev tswj qhov kub thiab txias, PU raug pom zoo; rau cov kev xav tau dav dav, pob zeb wool lossis thickened EPS yog txaus.
Xav txog koj cov peev nyiaj: Tus nqi xaj los ntawm qis tshaj mus rau siab tshaj yog: EPS < PU < Pob zeb wool.
Q: Dhau li ntawm cov sandwich panels, puas muaj lwm yam kev lag luam thiab kev siv tau zoo?
A: Yog. Ntxiv nrog rau kev siv cov sandwich vaj huam sib luag ncaj qha, muaj ob txoj kev xaiv:
Ntxiv cov ntawv ci: Ua ntej txhim kho cov xim hlau xim, ib txheej ntawm ob -sided reflective foil yog nteg, uas tuaj yeem cuam tshuam lub hnub ci hluav taws xob kub. Qhov no yog ib qho yooj yim, kev lag luam, thiab siv tau zoo ntawm kev rwb thaiv tsev kub thiab cua txias.
Siv cov cua sov- insulating txheej: Siv cov cua sov tshwj xeeb- insulating txheej nrog siab reflectivity rau saum npoo ntawm cov xim -coated steel coil tuaj yeem cuam tshuam feem ntau ntawm lub hnub ci hluav taws xob, txo qhov kub ntawm lub ru tsev thiab sab hauv.
Q: Dab tsi yog cov ntsiab lus tseem ceeb thaum lub sij hawm tsim kho uas cuam tshuam rau qhov kawg rwb thaiv tsev nyhuv?
A: Cov ntsiab lus ntawm kev tsim kho yog qhov tseem ceeb; Kev tuav tsis raug tuaj yeem tsim cov txuas hniav thermal, txo qhov cuam tshuam ntawm rwb thaiv tsev. Cov ntsiab lus hauv qab no yuav tsum tau sau tseg:
** Rwb thaiv tsev paj rwb yuav tsum tau pw nruj nreem: ** Yuav tsum tsis muaj qhov sib txawv ntawm cov paj rwb rwb thaiv tsev. Txhua qhov khoob yuav tsum tau kho kom sai; qhov no yog qhov tseem ceeb los xyuas kom meej qhov ua tau zoo ntawm cov rwb thaiv tsev.
** Tiv thaiv cov thermal bridging effect:** Thaum tshav kub kub tuaj yeem poob raws cov pob qij txha ntawm cov hlau keel lossis panels, tsim cov txuas hniav thermal. Yog li ntawd, thermal rwb thaiv tsev ntaub yuav tsum tau muab tso rau ntawm keel thiab panels, thiab kaw.
** Kev tswj dej kom zoo: ** Thaum cov paj rwb rwb thaiv tsev ntub dej, nws cov rwb thaiv tsev ua haujlwm yuav poob qis. Cov dej noo-cov ntaub ntawv pov thawj lossis cov dej noo- cov ntaub ntawv pov thawj yuav tsum tau muab tso rau hauv qab cov xim hlau phaj kom tiv thaiv cov dej noo los ntawm corroding txheej rwb thaiv tsev.
Q: Dab tsi yog qee cov lus pom zoo txog lub thickness ntawm txheej txheej thiab cov khoom tseem ceeb?
A: Yog. Lub steel phaj thickness txiav txim siab lub zog ntawm cov qauv, thaum cov khoom tseem ceeb thickness txiav txim siab qhov kev ua tau zoo ntawm rwb thaiv tsev. Kev sib xyaw kom zoo ntawm ob qho tib si yog qhov tsim nyog.
Hlau phaj thickness (0.3mm - 0.8mm): Rau lub ru tsev thiab phab ntsa, 0.4mm - 0.5mm yog ib qho kev xaiv, ua tau raws li qhov yuav tsum tau muaj zog thiab durability ntawm cov vaj tsev zoo tib yam. Rau siab load-cov uas yuav tsum tau muaj (xws li cov tuam tsev loj loj), 0.5mm los yog ntau tshaj yuav tsum tau xaiv.
Core khoom thickness (50mm - 150mm): Rau lub Hoobkas zoo tib yam, 75mm raug pom zoo ua qhov pib. Rau qhov xav tau kev rwb thaiv tsev siab lossis hauv thaj chaw txias heev, 100mm lossis txawm tias tuab tuaj yeem siv tau; 50mm tuaj yeem xaiv rau cov tsev nyob ib ntus lossis hauv thaj tsam yav qab teb.
