Nyob rau hauv cov txheej txheem ntawm cov khoom siv teeb pom kev zoo, skylighting sheets nthuav tawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv, txheej txheem tsim khoom, thiab kev siv. Cov kev sib txawv no tsis tsuas yog tshwm sim hauv cov tsos thiab kev ua haujlwm yooj yim tab sis tseem cuam tshuam rau lawv cov xwm txheej siv tau, kav ntev, thiab tag nrho cov nqi. Kev nkag siab txog qhov sib txawv no pab ua kom raug xaiv hauv kev ua haujlwm engineering.
Thawj qhov sib txawv yog nyob rau hauv hom substrate. Tam sim no, cov ntawv tseem ceeb ntawm lub teeb pom kev zoo tuaj yeem muab faib ua peb pawg: fiberglass reinforced yas (FRP) skylighting sheets, polycarbonate (PC) skylighting sheets, thiab acrylic iav (PMMA) skylighting sheets. FRP skylighting sheets siv unsaturated polyester cob raws li cov matrix, embedded nrog fiberglass mesh, tsim ib tug sib sib zog nqus thiab siab - lub zog composite qauv. Lawv muaj kev tiv thaiv zoo rau cov kua qaub thiab alkali corrosion thiab muaj tus nqi nruab nrab, ua rau lawv siv dav hauv thaj chaw loj -, thaj chaw huab cua ib puag ncig xws li cov nroj tsuag kev lag luam thiab tsev cog khoom ua liaj ua teb. PC (polycarbonate) skylights yog molded los ntawm polycarbonate resin, ua tiav lub teeb xa tawm ntau tshaj 85%. Lawv qhov kev cuam tshuam tsis zoo yog qhov zoo tshaj rau cov iav zoo tib yam, thiab lawv muaj qhov kub thiab txias tsis kam. Txawm li cas los xij, lawv ua rau muaj kev pheej hmoo ntawm yellowing nyob rau hauv ntev - lub sij hawm UV raug, ua rau lawv zoo dua rau cov pej xeem venues los yog ib ntus vaj tse nyob qhov twg muaj kev nyab xeeb thiab kev cuam tshuam tsis kam yog qhov tseem ceeb. PMMA (polyacrylic acid) skylights yog tsim los ntawm acrylic resin, ua tiav lub teeb xa tawm ntawm kwv yees li 92%. Lawv tsim tsis tshua muaj neeg sib xws thiab mos lub teeb refraction thiab muaj huab cua tsis zoo; Txawm li cas los xij, lawv qhov hardness qis dua thiab lawv tau yooj yim khawb. Lawv feem ntau yog siv rau hauv cov khoom lag luam, siab - kho kom zoo nkauj kawg, thiab lwm yam kev siv nrog cov kev xav tau zoo kho qhov muag.
Qhov sib txawv ntawm cov txheej txheem tsim khoom thiab kev kho saum npoo kuj tseem ceeb. Standard skylights khaws cov xim qub thiab cov qauv yooj yim ntawm lub substrate kom tau raws li cov teeb pom kev dav dav thiab lub zog xav tau; skylights ua haujlwm tau txais cov khoom tshwj xeeb xws li UV tsis kam, nplaim hluav taws xob, tiv thaiv -fogging, thiab rwb thaiv tsev kub los ntawm co-extrusion coatings, deg embossing, los yog ntxiv ntawm modifiers. Piv txwv li, UV- cov txheej txheem tiv thaiv tuaj yeem ua rau cov txheej txheem kev laus qeeb qeeb, thaum cov nplaim hluav taws- cov txheej txheem tiv thaiv tau ua raws li cov cai nruj dua. Cov khoom no yog irreplaceable nyob rau hauv tshwj xeeb ib puag ncig los yog siab - tej yaam num.
Hla - cov duab ntu kuj ua rau qhov pom qhov sib txawv. Pav ca - vaj huam sib luag qauv muab cov qauv tsim yooj yim thiab cov teeb pom kev zoo sib xws, ua rau lawv tsim nyog rau qhov me me lossis cov teeb pom kev zoo. Wavy-cov qauv zoo li siv cov npoo nkhaus los txhim kho cov dej thiab cua tiv thaiv, thiab tau siv dav hauv lub ru tsev skylights. Hollow- vaj huam sib luag cov qauv (xws li honeycomb thiab I-beam structures) ua tiav cov rwb thaiv tsev kub thiab suab nrov txo los ntawm cov huab cua hauv cov khaubncaws sab nraud povtseg, muab cov txiaj ntsig zoo hauv qhov txias lossis siab - thaj chaw kub. Cov ntoo khaub lig sib txawv- ntu tsis tsuas yog cuam tshuam rau kev siv tshuab thiab thermal kev ua tau zoo tab sis kuj ua rau muaj qhov sib txawv ntawm qhov pom kev pom thiab yooj yim ntawm kev tsim kho.
Tsis tas li ntawd, qhov sib txawv ntawm cov xim thiab lub teeb transmittance nthuav lawv daim ntawv thov. Hom pob tshab ua kom pom qhov zoo tshaj plaws ntawm lub teeb pom kev zoo, semi- hom pob tshab soften lub teeb siv thaum tuav lub teeb kom tsawg, thiab hom xim muaj peev xwm kho cov spectral muaj pes tsawg leeg thiab koom nrog kev zoo nkauj hauv vaj tse. Txhua hom plays lub luag haujlwm tshwj xeeb hauv cov xwm txheej xws li toj roob hauv pes tsev cog khoom thiab chaw lag luam.
Hauv cov ntsiab lus, qhov sib txawv ntawm cov khoom siv, cov txheej txheem tsim khoom, ntoo khaub lig- cov duab ntu, thiab cov khoom siv kho qhov muag ntawm lub teeb pom kev txiav txim siab txog lawv qhov kev ua tau zoo thiab siv tau ntau yam. Kev xaiv qhov project yuav tsum yog raws li kev txiav txim siab ntawm ib puag ncig, kev xav tau ntawm kev thauj khoom, kev xav tau ntawm kev xa mus rau lub teeb, thiab kev xav txog nyiaj txiag kom ua tiav qhov kev sib tw zoo ntawm kev ua haujlwm thiab cov txiaj ntsig.
