Pre Painted Galvanized Steel

Qhov "fireproof" muaj nuj nqi ntawm cov xim pleev xim ua ntej galvanized steel, ntau dua, yog hais txog nws qhov hluav taws kub tsis kam thiab hluav taws kub. pre pleev xim rau galvanized steel tsis txhais hais tias cov khoom yuav tsis hlawv tag nrho, tab sis tuaj yeem ncua kev sib kis ntawm cov nplaim taws, tiv thaiv cov txheej txheem combustion, thiab tswj cov txheej txheem kev ncaj ncees rau lub sijhawm thaum muaj hluav taws kub, kom tau txais lub sijhawm tseem ceeb rau kev khiav tawm thiab tua hluav taws.

Kev tiv thaiv hluav taws ua haujlwm ntawm cov xim pleev xim ua ntej galvanized steel yog tsuas yog pom los ntawm kev sib koom ua ke ntawm peb yam hauv qab no:

Lub hauv paus ntawm prepainted galvanized steel yog nplaim retardant txheej:

Cov xim pleev xim ua ntej galvanized steel tuaj yeem paub qhov txuas ncaj qha thiab tseem ceeb tshaj plaws ntawm kev tiv thaiv hluav taws. Los ntawm kev ntxiv cov nplaim hluav taws tshwj xeeb rau qhov ua tiav thiab rov qab xim ntawm cov xim pleev xim ua ntej galvanized steel thaum ntsib nplaim taws, cov txheej yuav muaj cov tshuaj tiv thaiv lub cev thiab tshuaj lom neeg:

· pre pleev xim rau galvanized steel muaj cua sov nqus thiab cua txias ua haujlwm: qee cov nplaim hluav taws xob (xws li txhuas hydroxide thiab magnesium hydroxide) yuav decompose thaum rhuab thiab nqus cua sov ntau, thiaj li txo qhov kub ntawm cov xim ua ntej galvanized steel nto thiab ncua sij hawm kom ncav cuag qhov hluav taws kub.

· pre pleev xim rau galvanized steel cov ntaub ntawv thermal rwb thaiv tsev cov pa roj carbon txheej: nplaim retardant tuaj yeem txhawb cov txheej kom nthuav dav thiab carbonize ntawm qhov kub thiab txias los tsim cov txheej tuab thiab ntxeem tau carbonized. Cov txheej txheem carbonized no ua "thermal barrier", uas tuaj yeem tsis tsuas yog cais cov pa oxygen hauv qab no, tab sis kuj thaiv cov cua sov hloov ntawm cov nplaim taws mus rau lub hauv paus phaj (steel phaj).

· Dilution ntawm oxygen thiab combustible gas: ib co nplaim hluav taws yuav ua rau incombustible gas (xws li dej vapor, carbon dioxide, nitrogen, thiab lwm yam) thaum decomposing. Cov pa roj no tuaj yeem dilute qhov concentration ntawm oxygen thiab combustible pyrolysis gas rau ntawm cov khoom nto, thiaj li inhibit combustion.

· Interruption ntawm combustion saw cov tshuaj tiv thaiv: ib co halogenated los yog phosphorous nplaim retardants tuaj yeem ntes cov dawb radicals generated thaum combustion, cuam tshuam cov saw cov tshuaj tiv thaiv ntawm combustion thiab "tua" nplaim taws los ntawm cov tshuaj theem.

Hom hluav taws kub retardant txheej ntawm pre pleev xim rau galvanized steel:

· Intumescent hluav taws retardant txheej: qhov no yog qhov feem ntau siv thiab ua tau zoo. Hauv qhov hluav taws kub, cov txheej yuav nthuav dav kaum ob lossis ntau pua zaus los tsim cov txheej txheej tuab tuab, yog li cov thermal rwb thaiv tsev zoo heev.

· Tsis yog -expansive hluav taws kub retardant txheej: nws yog tsuas yog siv rau tshav kub rwb thaiv tsev thiab oxygen cais los ntawm nws high melting point, tsis tshua muaj thermal conductivity los yog iav zaj duab xis generated tom qab rhuab.

Foundation: hlau puag phaj

Lub hauv paus phaj ntawm pre pleev xim rau galvanized steel (feem ntau galvanized steel phaj, aluminized zinc steel phaj los yog txhuas-magnesium manganese phaj) nws tus kheej tsis yog - cov khoom siv hluav taws xob (Class A). Qhov no yog lub hauv paus ntawm lub cev ntawm nws txoj haujlwm tiv thaiv hluav taws.

· Tsis koom nrog hauv kev sib txuas: hlau substrates tsis ua roj, uas yog qhov txawv ntawm cov ntoo, yas, thiab lwm yam ntaub ntawv.

· Muab kev txhawb nqa: Hauv qhov hluav taws kub, txawm tias cov organic txheej ntawm qhov chaw raug kub hnyiab, cov hlau substrate tuaj yeem tswj nws cov duab thiab lub zog rau qee lub sijhawm los tiv thaiv cov khoom hauv lub tsev los ntawm kev tawg ntxov ntxov.

Zuag qhia tag nrho: hluav taws kub tsis kam ntawm pre painted galvanized steel system

Thaum cov hlau pleev xim ua ntej galvanized tau ua tiav rau hauv lub ru tsev vaj huam sib luag lossis phab ntsa vaj huam sib luag thiab ntsia rau ntawm lub tsev qauv, nws qhov kev ua haujlwm tsis zoo yuav tsum raug suav hais tias yog qhov system. Qhov no suav nrog:

· Rwb thaiv tsev tom qab xim yob: Yog hais tias lub kaw lus muaj xws li rwb thaiv tsev (xws li pob zeb wool, iav ntaub plaub), qhov ntsuas hluav taws kub ntawm cov ntaub ntawv no (uas yuav tsum yog Class A incombustible khoom) yog qhov tseem ceeb. High- zoo fireproof xim steel phaj feem ntau ua ke nrog pob zeb wool los ua "pob zeb wool sandwich phaj", thiab nws tag nrho cov hluav taws kub endurance yuav ncav cuag ntau tshaj 1 teev.

· Kev teeb tsa thiab kev sib txuas ntawm cov xim pleev xim ua ntej galvanized steel: lapping ntawm daim hlau thiab kho hom ntawm daim hlau thiab purlins yuav cuam tshuam seb nplaim hluav taws kub thiab kub flue gas yuav kis tau los ntawm qhov khoob.

Ntu 2: Piv txwv

Rau kev nkag siab zoo dua, peb piav qhia ntau yam kev thov tshwj xeeb thiab hom khoom:

Piv txwv 1: Industrial cog thiab logistics warehouse

· Scenario piav qhia: Lub tsev khaws khoom loj loj nrog ntau cov khoom, suav nrog cov khoom tawg. Thaum hluav taws tshwm sim, nws kis tau sai heev.

· Cov khoom siv: pob zeb wool sandwich board los yog ua ntej pleev xim rau galvanized steel veneer nrog kev ua tau zoo fireproof txheej.

· Kev tiv thaiv hluav taws muaj nuj nqi:

· Tiv thaiv kev sib kis ntawm hluav taws: yog tias lub ru tsev ru tsev lossis phab ntsa muab cov khoom siv hluav taws xob ua ntej pleev xim rau cov hlau, thaum muaj hluav taws kub hauv zos, cov nplaim hluav taws yuav tsis tawg sai sai rau cov ntawv uas nyob ib sab. Cov nplaim retardant txheej tsim ib txheej char uas txwv cov nplaim taws mus rau qhov chaw pib.

· Kev tiv thaiv ntawm lub tsev tsim: hlau puag phaj thiab cov khoom siv hauv pob zeb wool core tuaj yeem thaiv qhov kub thiab txias, tiv thaiv hluav taws los ntawm kev kub hnyiab ntawm lub ru tsev nyob rau lub sijhawm luv luv, uas ua rau tag nrho lub cev qhuav dej, thiab tsim cov xwm txheej rau cov neeg ua haujlwm khiav tawm hauv lub tsev khaws khoom thiab cov neeg tua hluav taws sab hauv.

· Ua raws li cov cai hauv tsev: cov tsev zoo li no feem ntau yuav tsum siv cov khoom siv hauv tsev nrog qhov ntsuas hluav taws xob tsis pub tsawg tshaj 1 teev. Fireproof pre pleev xim rau galvanized steel yog ib qho kev daws teeb meem kom tau raws li qhov yuav tsum tau ua.

Piv txwv 2: Tsis yog- bearing sab nrauv phab ntsa ntawm siab -nce tsev

· Cov ntsiab lus piav qhia: Niaj hnub nimno siab- cov tsev nce siab siv cov xim coated daim hlau ua cov ntaub thaiv phab ntsa lossis cov kab zoo nkauj. Lub tsev sab nrauv phab ntsa hluav taws kub muaj qhov "chimney effect" thiab kis tau sai heev (saib cov lus qhia tau kawm los ntawm Glenfield Tower hluav taws hauv London).

· Daim ntawv thov khoom: Class A fireproof hlau composite phaj.

· Kev tiv thaiv hluav taws muaj nuj nqi:

· Tshem tawm cov nplaim taws sib kis raws lub ntsej muag: Chav Kawm A fireproof xim coated composite phaj, uas tsis yog -combustible mineral wool li cov khoom tseem ceeb thiab hlau phaj nrog fireproof txheej ntawm ob sab. Txawm hais tias hluav taws tshwm sim hauv tsev, nws nyuaj heev rau cov nplaim taws tawg los ntawm sab nraum zoov thiab kis mus rau sab nraud ntawm phab ntsa sab nrauv.

· Ua kom muaj kev nyab xeeb tag nrho: daim ntawv thov no nruj me ntsis txwv kev siv cov khoom siv hluav taws xob ntawm lub façade ntawm lub tsev thiab yog qhov yuav tsum tau ua kom pom tseeb ntawm lub ntiaj teb tam sim no lub tsev tiv thaiv hluav taws.

Kev tiv thaiv hluav taws muaj nuj nqi ntawm cov xim pleev xim ua ntej galvanized steel yog qhov system engineering, uas ua ke:

· Tshuaj tiv thaiv (nplaim retardant txheej realizes active tiv thaiv los ntawm tshav kub nqus, char tsim, vapor theem suppression, thiab lwm yam.)

· Kev tiv thaiv lub cev (tsis yog- cov hlau nplaum uas tsis muaj hluav taws xob muab kev txhawb nqa zaum kawg)

· Kev sib koom ua ke (ua kom muaj hluav taws kub zoo ua ke nrog cov ntaub ntawv rwb thaiv tsev thiab cov qauv sib txuas)

Thaum xaiv cov khoom siv hluav taws xob ua ntej pleev xim rau galvanized steel, tsis txhob mloog lo lus "kev tiv thaiv hluav taws", tab sis ua tib zoo mloog nws cov ntawv pov thawj hluav taws tshwj xeeb (xws li Class A thiab B1 hauv Suav GB 8624 tus qauv, lossis A2, B-}s1, D0 hauv EU EN 13501-1 tus qauv) thiab cov ntawv pov thawj hluav taws kub hnyiab GB7 raws li kev cai 9 (s) ntawm tej yaam num tsim tsev.
