Polycarbonate (PC), thermoplastic polymer muab tau los ntawm cov tshuaj tiv thaiv ntawm bisphenol A nrog phosgene (COCl₂), tau hloov pauv cov toj roob hauv pes ntawm vaj tse glazing thiab vov tsev daim ntaub ntawv txij li thaum nws coj mus muag kev taw qhia nyob rau hauv 1958. Nrog ib tug refractive Performance index ntawm 1.586, tshwj xeeb gravity ntawm 1.5cm / span 4,20 g.℃rau +120℃, cov khoom siv no tuav lub luag haujlwm tshwj xeeb hauv cov ntaub ntawv tsim kho hierarchy-kev cuam tshuam kev cuam tshuam kwv yees li 250 npaug ntawm cov iav ntab thaum hnyav li ib nrab li ntau ntawm ib cheeb tsam.
Teeb meem chaw ntau pob Canopy Tsis muaj leej twg pom tuaj
Yog li ntawm no yog qhov tshwm sim nrogpolycarbonate vov tsevuas hloov txhua yam.
Rov qab rau xyoo 1980 thiab 90s thaum ntxov, cov kws tsim vaj tsev tau khiav mus rau tib qhov teeb meem nrog cov pob tshab ru tsev loj. iav hnyav. Zoo li, absurdly hnyav. Ib square meter ntawm tus qauv ntab iav ntawm 6 hli thickness khiav ib ncig ntawm 15 kilograms. Sim ncua lub chaw ncaws pob football nrog qhov ntawd. Qhov kev xav tau ntawm cov qauv steel ib leeg yuav ua rau feem ntau ntawm cov haujlwm.
Acrylic (Plexiglass) zoo li cov lus teb pom tseeb rau ib pliag. Lighter dua iav, tsim nyog meej, dlej UV tsis kam. Tab sis tom qab ntawd ib tug neeg inevitably pov pob zeb. Los yog lawg tuaj. Lossis tus neeg ua haujlwm tu tau tso ib lub cuab yeej. Thiab mam li nco dheev koj tau tawg cov panels los nag rau ntawm pawg neeg hauv qab no.
Polycarbonate daws ob qho teeb meem ib zaug. Tib 6mm thickness? Kwv yees li 7.2 kg ib square meter. Thiab zoo unbreakable. Kuv tau pom cov duab ntsuas ntawm 4kg steel pob poob los ntawm 9.5 meters mus rau 3 hli cov ntawv polycarbonate. Peb zaug ua ke. Nws thaws. Daim ntawv tsis tawg.
Qhov ntawd tsis yog kev lag luam fluff- qhov ntawd yog qhov ua tau zoo li cas cov khoom coj.
Thermal Expansion yuav rhuav koj lub hnub
Yog hais tias muaj ib yam installers kawm txoj kev nyuaj nrog polycarbonate vov tsev, nws yog qhov no: cov khoom txav.
Lub linear thermal expansion coefficient zaum ntawm kwv yees li 0.065-0.070 mm / m / degree. Qhov ntawd yog kwv yees li rau lub sijhawm siab dua cov hlau thiab yim npaug siab dua iav. Khiav lej ntawm 10-meter vaj huam sib luag muaj 55℃kub viav vias ntawm lub caij ntuj no thiab lub caij ntuj sov, thiab koj tab tom saib ze li ntawm 36 hli ntawm qhov hloov pauv.
Tsis zoo li ntau txog thaum koj tau bolted nws rigidly nyob rau hauv qhov chaw. Tom qab ntawd koj tau buckling. Warping. Cov npoo tawg. Vaj huam sib luag pop- tawm. Txhua tus paub txog roofer muaj dab neeg txaus ntshai.
Kev kho tsis nyuaj -qhov loj loj rau fasteners, clearance kom raug ntawm cov npoo, tshwj xeeb expansion profiles-tab sis nws yuav tsum tau npaj. Kuv tau nyeem cov chaw tsim khoom siv cov lus qhia uas ua rau muaj txiaj ntsig thiab ua siab tawv rau cov lus ceeb toom thermal nthuav dav vim tias ntau tus neeg tsis quav ntsej lawv.
Ntawm no yog cov qauv tsis muaj leej twg thab xam kom txog thaum tom qab tej yam tsis raug:
ΔL = L × ΔT × K
Qhov twg L yog daim ntawv ntev, ΔT yog qhov sib txawv ntawm qhov kub thiab txias, thiab K yog qhov nthuav dav coefficient (0.065 rau cov ntshiab / dawb). Yooj yim txaus. Txawm li cas los xij cov chaw tsim kho tseem tsim cov ru tsev buckled txhua lub caij ntuj sov.
Multiwall vs. Khoom: Kev Lag Luam Rwb thaiv tsev -tawm
Qhov no yog qhov uas tej yam tau txais txiaj ntsig tiag tiag los ntawm kev tsim kev tshawb fawb pom.
Khoom polycarbonate muab qhov siab tshaj plaws kev tiv thaiv thiab optical clarity. Lub teeb kis tau tus mob nyob ib ncig ntawm 89-90%. Zoo indestructible. Tab sis thermally? Nws yog ib qho yooj yim pane ntawm iav nrog qhov sib txawv refractive index. R-tus nqi nyob ib ncig ntawm 0.9-1.0 rau cov tuab tuab.
Twinwall polycarbonate-ob daim ntawv sib npaug nrog cov tav sab hauv tsim kom muaj huab cua chamber- hloov qhov sib npaug tag nrho. Daim ntawv txheem 6 hli twinwall muaj R- tus nqi kwv yees li 1.54-1.6. Tseem tsis tau zoo los ntawm cov txheej txheem rwb thaiv tsev phab ntsa, tab sis muaj txiaj ntsig zoo dua li cov khoom glazing.
Tom qab ntawd koj nkag mus rau hauv qhov tob multiwall configurations:
| Kev teeb tsa | Hom Thickness | R-Tus nqi (kwv yees) | Lub teeb kis |
|---|---|---|---|
| Khoom | 3-6 hli | 0.9-1.0 | 88-90% |
| Twinwall | 6mm ib | 1.54-1.6 | 80-82% |

| Twinwall | 16 hli | 2.3-2.5 | 70-76% |
| 5- Phab ntsa | 25 hli | 3.0-3.2 | 50-60% |
Qhov kev poob qis rov qab los ua pom tseeb sai sai. Koj tuaj yeem ua tus nqi rwb thaiv tsev peb npaug los ntawm kev mus los ntawm phab ntsa twinwall mus rau tsib- phab ntsa, tab sis koj poob ze li ib feem peb ntawm koj lub teeb kis hauv cov txheej txheem. Rau cov ntawv thov tsev cog khoom, qhov kev pauv ntawd -tawm qhov teeb meem loj heev.
UV Degradation: Tsib - Xyoo Cliff
Uncoated polycarbonate raug tshav ntuj ncaj qha yuav pib daj nyob rau hauv tsib mus rau xya xyoo. Qhov no tsis yog kev kwv yees- nws yog cov ntaub ntawv tshawb fawb. UV hluav taws xob rhuav tshem cov saw hlau polymer los ntawm daim duab- oxidation, tsim kom muaj tus yam ntxwv zoo li amber tint uas qw "khoom pheej yig xyoo 2015."
Kev lag luam tau daws qhov no ntau xyoo dhau los nrog co-extruded UV tiv thaiv txheej. Feem ntau 50-80 microns tuab, sib koom ua ke thaum tsim khoom es tsis yog siv los ua txheej txheej. Cov ntawv tiv thaiv UV kom raug muaj kev lees paub ntawm 10-15 xyoo tiv thaiv lub teeb kis tau zoo lossis hloov xim.
Tab sis ntawm no yog qhov uas ua rau tib neeg mus ncig: kev tiv thaiv UV feem ntau yog nyob ntawm ib sab nkaus xwb.
Nruab lub vaj huam sib luag upside down? Nrog koj zoo siab, koj nyuam qhuav voided koj warranty thiab guaranteed ua tsis tiav ntxov ntxov. Feem ntau cov tuam ntxhab kos rau sab UV, tab sis kuv tau ntsib kev teeb tsa uas tsis muaj leej twg cuam tshuam los xyuas. Cov vaj huam sib luag saib zoo rau txog kaum yim hli.
Nto- siv UV txheej (raws li tsis yog co-extruded txheej) muaj kev tiv thaiv tsis zoo. Cov txheej tuaj yeem khawb, hnav, lossis tev, tawm hauv lub substrate raug. Nco ntsoov xyuas cov txheej txheem tiv thaiv UV ua ntej yuav khoom.
Kev Cwj Pwm Hluav Taws Kub Nyuaj Nyuaj
Polycarbonate tsis yog tsis yog -combustible. Cia li tawm ntawm txoj kev tam sim ntawd.
Txawm li cas los xij, nws yog dab tsi yog tus kheej - tua. Tshem tawm cov nplaim taws thiab cov khoom siv tsis txhob hlawv. Cov qib txheem feem ntau ua tiav UL 94 V-2 lossis HB cov qhab nia- tsis zoo nkauj, tab sis ua tau raws li cov cai hauv tsev rau cov khoom siv hluav taws xob xa hluav taws xob.
Cov khoom softens nyob ib ncig ntawm 150-160 degree. Nyob rau hauv kev raug hluav taws kub, nws yuav deform thiab nws thiaj li ignite. Tab sis qhov tseem ceeb, nws tsis tsim cov nplaim taws tseem ceeb uas tuaj yeem kis hluav taws mus rau qhov chaw hauv qab no, thiab cov pa luam yeeb tseem qis dua piv rau lwm cov thermoplastics.
Rau cov ntawv thov uas xav tau kev ua haujlwm tua hluav taws ntau dua, cov nplaim taws- muaj qib retardant. Cov no tuaj yeem ua tiav UL 94 V-0 (tus kheej- tua tsis pub dhau 10 vib nas this) lossis txawm tias qhov ntsuas 5VA. Kev lag luam tawm -? Feem ntau qee qhov txo qis hauv qhov pom kev pom tseeb thiab nce nqi. FR-qib polycarbonate sau kwv yees li 35-50% kim dua li cov khoom siv.
Cov cai hauv tsev nyob sab Europe siv Euroclass system (EN 13501-}1), qhov twg polycarbonate feem ntau ua tiav B-}s1,d0 kev faib tawm-txhim kho rau hluav taws sib kis, tsim hluav taws xob tsawg, tsis muaj nplaim taws. Qhov ntawd yog qhov siv tau rau feem ntau cov ntawv thov vov tsev, txawm tias cov lej hauv zos sib txawv txaus uas koj yuav tsum tau txheeb xyuas cov cai ua ntej qhia.
Yog vim li cas Greenhouses hloov txhua yam
Cov tswv lag luam hauv tsev cog khoom tau tshawb pom polycarbonate hauv txoj hauv kev loj thaum xyoo 1990, thiab daim ntawv thov ua rau muaj kev nkag siab ntau dhau.
Iav greenhouses saib elegant. Lawv kuj tawg thaum lub caij hailstorms, poob cua sov sai heev los ntawm ib qho -pane glazing, yuav tsum tau hnyav structuring framing, thiab raug nqi ib tug hmoov zoo rau cua sov los ntawm sab qaum teb lub caij ntuj no. Polyethylene zaj duab xis raug nqi ib sab ntawm tsis muaj dab tsi tab sis degrades nyob rau hauv 4-5 xyoo thiab muab xoom rwb thaiv tsev.
Twinwall polycarbonate threads lub koob. Impact resistant txaus kom ciaj sia baseball-loj lawg. Insulative txaus los txiav cov nqi hluav taws xob los ntawm 30-40% piv rau ib lub khob iav. Lub teeb txaus uas aluminium framing txaus. Durable txaus los lav 10-15 xyoo kev pab them nqi.
Lub teeb diffusion khoom tau dhau los ua qhov txiaj ntsig tsis xav txog. Qhov twg iav tsim cov duab ntxoov ntxoo hnyav thiab kub kub, multiwall polycarbonate tawg tawm lub teeb tuaj thoob plaws qhov chaw loj hlob. Qee cov neeg cog qoob loo qhia txog kev txhim kho cov nroj tsuag zoo dua piv rau cov glazing ntshiab -tab sis kuv yuav lees paub qhov kev tshawb fawb ntawm qhov no tseem muaj kev sib tw me ntsis.
Drilling Tsis Muaj Kev Puas Tsuaj
Cov khoom siv polycarbonate zoo nkauj. Twinwall configurations? Tsawg zam txim.
Cov qauv sab hauv sab hauv txhais tau hais tias koj yog qhov tseem ceeb drilling los ntawm ntau lub nyias nyias es tsis yog cov khoom siv. Mus nrawm dhau, siv lub zog ntau dhau, lossis siv qhov tsis ncaj ncees lawm, thiab koj yuav tawg qhov nkag lossis tawm. Qee zaum ob leeg.
Kev xyaum ua qauv hu rau cov carbide ntse-tipped me ntsis, qeeb tus nqi pub, thiab rov qab daim ntawv nrog cov khoom seem los tiv thaiv kev tawg. Rau corrugated profiles, ib txwm xyaum ntawm lub ncov ntawm lub corrugation, yeej tsis lub hav. Dej pas dej ua ke nyob rau hauv ib lub hav fastener qhov guarantees nws thiaj li to.
Qhov teeb meem thermal expansion resurfaces ntawm no. Cov qhov ntsia hlau yuav tsum loj dua los ntawm tsawg kawg 3 hli dhau ntawm txoj kab uas hla. Tsis tas li ntawd, 35mm ntawm lub caij ntuj sov nthuav dav tsis muaj qhov twg mus tsuas yog mus rau hauv kev sib tsoo ib ncig ntawm lub fastener.
Cov ntsia hlau tshwj xeeb vov tsev zoo li POLY-FAST system tsim lub qhov loj tshaj plaws thermal expansion qhov tau txais thaum lub sijhawm teeb tsa- xyaum thiab tsav hauv ib qho haujlwm. Lawv raug nqi ntau dua tus qauv tus kheej -tappers. Lawv muaj nqis.
Kev sib piv Acrylic Txhua leej txhua tus tau yuam kev
"Polycarbonate lossis acrylic?"
Kuv hnov lo lus nug no tas li, feem ntau yog framed li yog hais tias lawv nyob nraum interchangeable. Lawv tsis yog. Cov khoom sib txawv. Cov khoom sib txawv. Daim ntawv thov sib txawv.
Acrylic muaj qhov pom kev pom zoo tshaj plaws (92% lub teeb kis tau tus mob vs . 88% rau polycarbonate) thiab zoo dua UV tsis muaj txheej txheej tshwj xeeb. Nws kuj tseem yooj yim dua rau polish rov qab kom pom tseeb tom qab kev puas tsuaj saum npoo. Rau cov ntawv thov uas qhov pom tseeb tseeb tseem ceeb- tsev cia puav pheej tso saib, siab-kawg muag glazing, cov khoom siv kho qhov muag-acrylic feem ntau ua rau muaj kev nkag siab ntau dua.
Tab sis acrylic shatters. Tsis zoo li iav, lees paub - nws tawg rau hauv qhov loj dua, tsis tshua muaj kev phom sij. Tseem, 17 × kev txhim kho dua iav cuam tshuam tsis kam tiv thaiv polycarbonate's 250 ×. Rau cov ntawv siv vov tsev uas cov khib nyiab cuam tshuam, huab cua raug, thiab kev taug kev ko taw sawv cev rau kev txhawj xeeb tiag tiag, qhov sib txawv no yog qhov txiav txim siab.
Acrylic kuj raug nqi tsawg dua-kwv yees li 35% hauv qab polycarbonate rau cov ntawv sib piv. Tus nqi zoo dua evaporates sai yog tias koj hloov cov panels tawg txhua ob peb xyoos.
Huab cua txias qhia lwm qhov kev xav. Acrylic ua tshwj xeeb tshaj yog nkig nyob rau hauv qis kub. Polycarbonate tuav nws cov kev cuam tshuam los ntawm tag nrho -40℃rau +120℃kev pabcuam. Northern climate installations yuav luag universally nyiam polycarbonate vim li no ib leeg.
Corrugated Profiles thiab lub zog sib npaug
Pav ca polycarbonate ntawv ua haujlwm zoo rau ntau daim ntawv thov. Tab sis corrugate cov khoom qub rau hauv cov qauv nthwv dej thiab lub zog pom meej dhia tau zoo heev.
Lub corrugation tsim geometric nruj- tib lub hauv paus ntsiab lus tom qab daim duab los qhia cov qauv nruj heev. Ib daim ntawv 0.8mm corrugated polycarbonate tuaj yeem ncua kev ncua deb ntawm kev txhawb nqa ntau dua li 3mm daim ntawv tiaj tus ntawm cov khoom zoo ib yam. Qhov hnyav txuag cascade los ntawm tag nrho cov qauv tsim.
Kev lag luam skylights thiab cov tsev ua liaj ua teb vam khom rau corrugated profiles raws nraim vim li cas. Sib piv cov qauv corrugation rau ib lub ru tsev hlau uas twb muaj lawm, thiab koj tuaj yeem sib xyaw ua ke lub teeb ci ntsa iab yam tsis tau hloov kho qhov sib txawv hauv qab purlin.
Qhov ntsuas kub rau corrugated profiles feem ntau khiav -40℃F txog +270℃F (kwv yees -40℃rau +132℃). Dav txaus rau txhua qhov kev thov sab nraum zoov luv luv ntawm cov txheej txheem kev lag luam raug.
Dab tsi tiag tua Polycarbonate ru tsev
Tsis yog lawg. Tsis yog cua. Tsis kub siab heev.
Kev ntxuav tsis raug thiab raug tshuaj lom neeg ua rau muaj kev ua tsis tiav ntau dua li cov xwm txheej huab cua puas tau.
Polycarbonate dissolves nyob rau hauv aromatic solvents. Acetone, toluene, benzene-cov no yuav huab, tawg, thiab thaum kawg ua kom cov khoom puas. Zoo li pom tseeb txog thaum koj paub tias cov tshuaj ntxuav qhov rais, tshwj xeeb tshaj yog cov tsim rau iav, feem ntau muaj ammonia lossis lwm yam tshuaj tsis haum.
Cov txheej txheem ntxuav kom nyab xeeb: xab npum me me thiab dej, ntaub mos muag lossis daim txhuam cev, tsis muaj txhuam txhuam. Qhov ntawd yog nws. Qee lub tuam txhab pom zoo rau diluted isopropyl cawv rau tawv tawv residue. Txhua yam uas muaj zog dua yuav tsum tau ua kom pom tseeb cov ntaub ntawv sib raug zoo.
Lub tshuab nqus tsev siab sawv cev rau lwm qhov yuam kev. Cov kwj dej muaj zog tuaj yeem yuam cov dej noo mus rau hauv ntau lub tsev (los ntawm lub kaus mom kawg lossis cov npoo puas), ua rau muaj kev loj hlob ntawm algae uas yuav luag tsis tuaj yeem tshem tawm. Tsawg- siab yaug nkaus xwb.
Condensation Control nyob rau hauv Multiwall Applications
Cov huab cua sab hauv uas muab rwb thaiv tsev? Lawv kuj ntxiab ya raws.
Standard multiwall polycarbonate panels nkoj nrog ob qhov kawg kaw tiv thaiv plua plav thiab kab nkag. Zoo rau ntsug glazing. Teeb meem rau ru tsev daim ntaub ntawv qhov kub cycling tsim nyob rau hauv condensation.
Los tiv thaiv -drip coatings ntawm sab hauv nto pab-lawv ua kom ya raws rau daim ntawv es tsis txhob hlaws, coj dej mus rau lub vaj huam sib luag ntug. Tab sis qhov kev daws teeb meem tseem ceeb tshaj qhov kawg yog qhov kawg - sealing nrog breathable daim kab xev rau ntawm ntug qis thiab cov ntaub nplaum rau ntawm ntug sab saud. Qhov no tso cai rau noo noo kom dim downward thaum tiv thaiv los nag infiltration los saum toj no.
Tsis quav ntsej cov ntsiab lus no thiab thaum kawg koj yuav pom cov tee dej raug tshem tawm hauv cov qauv vaj huam sib luag, txo qis kev sib kis ntawm lub teeb thiab muaj peev xwm txhawb cov pwm loj hlob hauv cov huab cua ntub.
Installation Slope tseem ceeb tshaj qhov koj xav
Qhov tsawg kawg nkaus pitch rau polycarbonate vov tsev: 5 degree, kiag li hauv pem teb. Zoo dua: 10℃lossis siab dua.
Hauv qab no cov ces kaum, dej pooling ua inevitable. Polycarbonate qhov saum npoo tsis zoo li hydrophobic, thiab cov av nkos tsim cov dams uas cuam tshuam cov dej noo ntxiv. Sawv ntsug dej nrawm UV degradation, txhawb nqa algae kev loj hlob ntawm cov pob qij txha, thiab nws thiaj li nrhiav tau txoj hauv kev los ntawm cov ntsaws ruaj ruaj uas yuav yooj yim tso dej ntws.
Cov pitches steeper kuj txhim kho tus kheej -kev tu tus cwj pwm thaum muaj xwm txheej los nag. Ntawm 15℃lossis siab dua, cov khib nyiab feem ntau ntxuav tawm yam tsis muaj kev cuam tshuam.
Ib lo lus ntawm Warranties
Kaum xyoo tau dhau los ua tus qauv kev lag luam rau kev tiv thaiv UV yooj yim thiab lub teeb kis tau zoo. Qee cov khoom lag luam zoo thawb mus rau 15 lossis 25 xyoo. Ua tib zoo nyeem cov ntawv zoo.
Feem ntau qhov kev lees paub tsis suav nrog kev puas tsuaj rau lub cev (pom tseeb), tab sis kuj tsis suav nrog kev puas tsuaj los ntawm kev teeb tsa tsis raug, cov khoom siv tsis sib xws, tshuaj lom neeg raug, thiab tsis ua raws li kev saib xyuas. Lub warranty guarantees cov ntaub ntawv kev ua tau zoo yog tias koj tau ua txhua yam kom raug. Ua pov thawj tias koj tau ua, thiab hmoov zoo.
