1. Hauv galvanized steel vov tsev thiab phab ntsa tej yaam num, dab tsi cov cuab yeej tseem ceeb yog feem ntau xav tau kom ua tiav qhov cua thiab teeb pom kev zoo?
Nyob rau hauv niaj hnub lub teeb steel qauv Hoobkas cov tsev, cov kev daws teeb meem yog siv kev sib xyaw ua pa thiab teeb pom kev zoo ru tsev ventilators (tseem hu ua qhov cua louvers lossis qhov cua skylights). Qhov no yog cov khoom siv vov tsev loj loj uas yog tsim los ntawm cov qauv hlau, cov skylight panels (feem ntau yog FRP skylight panels), thiab galvanized steel profiled nplooj ntawv (ua haujlwm los tiv thaiv nag thiab thaiv), ib txhij ua tau raws li plaub qhov kev xav tau loj ntawm qhov cua, tso pa tawm, tshem tawm cov pa taws, thiab teeb pom kev zoo. Feem ntau siv lub tshuab ua pa muaj xws li cov tshuab ua pa hauv lub ru tsev (tsawg cua tsis kam, muaj zog cua tsis kam) thiab nyias lub ru tsev ventilators (tsawg profile, tsis tshua muaj cua load), thiab phau ntawv, hluav taws xob, los yog hluav taws kub - sib ntaus sib tua txuas qhib thiab kaw li qub tuaj yeem xaiv raws li cov kev xav tau tshwj xeeb.
2. Yuav ua li cas txuas thiab kaw lub tshuab ua pa thiab lub teeb ci ntsa iab nrog cov xim galvanized-coated steel vov tsev vaj huam sib luag los tiv thaiv kev xau?
A: Qhov no yog ib qho kev sib tw tseem ceeb hauv lub ru tsev. Xyuas kom cov pa tawm- pov thawj kev ua haujlwm hinges ntawm "kev sib raug zoo" thiab "ntau kab ntawm kev tiv thaiv." Ua ntej, skylights nrog cov coefficient ntawm thermal expansion zoo ib yam li cov xim galvanized -coated steel vov tsev coils yuav tsum tau xaiv. Lub coefficient ntawm thermal expansion ntawm FRP skylights (kwv yees li 2.2 × 10⁻⁵ /℃) yog ze heev rau cov hlau (kwv yees li 1.5 × 10⁻⁵ / degree), deb tshaj ntawm PC panels, fundamentally txo sealing tsis ua hauj lwm los ntawm kub - induced. Thib ob, tag nrho cov khoom siv hlau (lub hauv paus, cov khoom sib txuas) yuav tsum kub -dip galvanized rau kev tiv thaiv corrosion, nrog zinc txheej thickness tsis pub tsawg tshaj 50μm los tiv thaiv xeb los ntawm kev puas tsuaj rau cov qauv tsis muaj dej. Nyob rau hauv cov nqe lus ntawm kev teeb tsa, qhov sib tshooj ntawm kev sib txuas ntawm flange thiab cov ntawv hlau vov tsev yuav tsum tau ua tiav welded thiab kaw nrog huab cua - tiv thaiv sealant kom ntseeg tau tias muaj kev sib txhuam zoo. Flashing thiab ua - hauv gutters yuav tsum tau muab tso rau ncaj qha dej nag mus rau lub ru tsev downpipes. Thaum kawg, thaum tso lub skylight panels, qhov sib nrug ntawm tus kheej -tapping screws ntawm lub nplhaib tshwj xeeb sealing yuav tsum tau khaws cia ntawm 150 ~ 200mm, thiab nws yuav tsum tau kho nrog txhuas siab phaj los yog roj hmab pads kom tsis txhob ncaj qha tawg lub panels.
3. Cov teeb ci ntsa iab puas tuaj yeem siv los hloov qee cov xim galvanized-coated profiled nplooj ntawv los daws teeb meem teeb pom kev zoo thiab siv nrog lub tshuab ua pa?
A: Yog lawm, qhov no yog ib txoj hauv kev siv ntau thiab kev lag luam kom ua tiav qhov ntev - qhov cua thiab teeb pom kev zoo nyob rau hauv loj -span Hoobkas lub tsev. Koj tuaj yeem hloov qee cov xim zoo tib yam- cov ntawv coated ntawm lub ru tsev nrog FRP (fiberglass reinforced polyester) skylights los tsim cov kab rov tav lossis ntsug pob tshab teeb pom kev zoo. Hais txog kev ua pa, lub tshuab ua pa tau nruab rau ntawm lub ru tsev tsis yog tsuas yog tshem tawm cua kub thiab pa taws los ntawm chav tsev xwb, tab sis lawv cov ntaub thaiv npog tuaj yeem ua los ntawm FRP skylight cov khoom kom ntxiv cov teeb pom kev nkag mus rau hauv chav tsev, tsis txhob glare, thiab ua kom lub teeb pom kev zoo hauv tsev. Los ntawm kev npaj qhov chaw thiab qhov sib nrug ntawm lub skylights, nws muaj peev xwm ua tiav lub teeb pom kev zoo thaum nruab hnub, tsim kom muaj txiaj ntsig zoo thiab lub zog-txuag kev sib xyaw ntawm "pas pa taws + teeb pom kev zoo" ua ke nrog lub tshuab ua pa.
4. Dab tsi yog lub hauv paus ntsiab lus rau kev teeb tsa thiab kev siv cov xim galvanized-coated steel sheet tej yaam num thaum tsim cov tshuab no?
A: Lub hauv paus ntsiab lus ntawm kev npaj tag nrho yog feem ntau "natural, npaum, thiab complementary." Rau qhov cua, qhov cua ntsawj ntshab yuav tsum tau teem caij raws qhov siab tshaj plaws ntawm lub Hoobkas ru tsev (kab kab) raws li lub ntsiab axis los pab txhawb qhov tsis siv neeg nce siab ntawm cov cua kub kom tso pa tawm thiab tshem tawm cov pa phem; Nyob rau tib lub sijhawm, lub qhov rais qhib qhov cua yuav tsum tau tsim rau ntawm phab ntsa gable ntawm lub tsev los tsim convection. Rau cov teeb pom kev zoo, nws yuav tsum tau ua ke nrog kev teeb tsa ntawm lub qhov cua, nrog rau cov cua ntsawj ntshab, sab teeb pom kev zoo, thiab hloov cov teeb pom kev zoo ua rau peb -dimensional array. Tsis tas li ntawd, ua tiav cov kev tshuaj xyuas thiab kev saib xyuas yuav tsum tau tshwj tseg, thiab cov neeg ua haujlwm raug txwv tsis pub taug kev lossis sawv ncaj qha rau ntawm cov teeb pom kev zoo. Tag nrho cov kev tshuaj xyuas yuav tsum tau ua los ntawm kev taug kev ntawm kev nyab xeeb hooks nyob rau hauv lub grooves ntawm lub ru tsev steel daim hlau kom tsis txhob tawg lub panels thiab ua rau muaj kev nyab xeeb xwm txheej.
5. Hais txog kev xaiv cov khoom, cov txheej txheem thiab cov platings yuav tsum tau xaiv rau qhov sib xws ntawm lub tshuab ua pa thiab lub teeb pom kev zoo?
A: Raws li kev ntseeg tau ntawm "kev sib txuam corrosion kuj lifespan nyob rau hauv tib cheeb tsam," steel thav duab ntawm lub ru tsev ventilators thiab skylights yuav tsum siv kub-dip galvanized los yog kub-dip aluminium-zinc coated substrates ntawm tib qib raws li lub ntsiab ru tsev panels. Nws raug pom zoo tias cov txhuas-zinc txheej txheej ntau dua lossis sib npaug ntawm 150g / ㎡, lub zog tawm los Ntau dua lossis sib npaug rau 280Mpa (ua tau raws li qhov xav tau ntawm chav tsev rau cov khoom sib txuam), thiab ob npaug - sab txheej ntawm 0.5mm tuab daim hlau. Rau cov nag npog (sab nraud tiv thaiv vaj huam sib luag), xim -coated steel phaj nrog tiv thaiv{11}}corrosion txheej ntawm ob sab yuav tsum tau siv. Qhov saum npoo ntawm cov hlau raug pov tseg yuav tsum tau tiv thaiv nrog fluorocarbon txheej txheej uas yog UV{13}}tiv taus thiab kev laus{14}} tiv taus. Rau FRP skylights uas ua ke nrog cov teeb pom kev zoo thiab kev tiv thaiv los nag, nws yuav tsum tau ntxiv Melinx UV-cov yeeb yaj kiab tiv thaiv thiab huab cua{17}}cov txheej txheem tiv thaiv kom ntseeg tau tias lawv cov huab cua tiv thaiv coefficient rau 10 mus rau 15 xyoo yog kwv yees tib yam li cov hlau loj loj.
