Vim li cas Lub Tuam Txhab Laus Tag Nrho tau pleev xim nrog hluav taws-Resistant Coatings?

 

Nyob rau hauv xyoo tas los no, ib qho kev pom zoo tau tshwm sim thoob plaws thaj chaw muaj kev lag luam thoob ntiaj teb: cov chaw tsim khoom qub, ntau hnub rov qab mus rau lub xyoo pua 20th los yog ua ntej, tab tom ua haujlwm ntau ntxiv nrog. hluav taws-resistant coatings. Los ntawm rusting steel beams nyob rau hauv cov ntaub ntawv pov tseg mills mus rau lub structural skeletons ntawm yav tas los automotive nroj tsuag, cov laus cov qauv yog coated nyob rau hauv tshwj xeeb xim thiab cov ntaub ntawv tsim los tiv taus huab cua kub thiab nplaim taws. Tab sis vim li cas qhov kev nce siab tam sim no hauv kev ua si? Puas yog nws tau tsav los ntawm txoj cai tswjfwm, kev txhawb nqa nyiaj txiag, lossis kev paub txog kev pheej hmoo hluav taws kub nyhiab hauv lub sijhawm ntawm kev hloov pauv huab cua thiab kev txhim kho hauv nroog? Kab lus no qhia txog ntau yam laj thawj tom qab qhov tshwm sim no, tshawb txog keeb kwm keeb kwm, cov qauv kev nyab xeeb niaj hnub, kev nce qib thev naus laus zis, thiab qhov cuam tshuam tiag tiag hauv ntiaj teb. Los ntawm kev tshuaj xyuas "vim li cas" thiab "yuav ua li cas," peb nthuav tawm qhov kev coj ua no tsis yog khaws cia cov cuab yeej cuab tam ua lag luam xwb tab sis kuj tseem tiv thaiv lub neej, khoom muaj nqis, thiab cov zej zog hauv lub ntiaj teb uas muaj hluav taws kub heev.

Lub laub siv hluav taws-resistant coatings rau cov qub factories stems los ntawm ib tug confluence ntawm yam. Cov cai nruj me ntsis hauv tsev, cov lus qhia tau kawm los ntawm kev kub ntxhov hauv kev lag luam, thiab cov txiaj ntsig kev lag luam ntawm kev rov ua dua tshiab dua li kev rhuav tshem tau txhua yam ua lub luag haujlwm tseem ceeb. Raws li xyoo 2025, nrog rau kev lag luam thoob ntiaj teb nrawm nrawm thiab cov chaw lag luam qub tau rov ua dua tshiab rau kev siv sib xyaw, qhov xav tau los txhim kho hluav taws xob tiv thaiv tau dhau los ua qhov tseem ceeb. Cov txheej txheej no, feem ntau intumescent lossis cementitious nyob rau hauv qhov xwm txheej, nthuav dav hauv qab cua sov los tsim cov txheej txheem insulating char, ncua kev sib tsoo thiab tso cai rau ntau lub sijhawm rau kev khiav tawm thiab tua hluav taws. Qhov no retrofitting nthwv dej qhia txog kev hloov pauv mus rau qhov chaw ruaj khov thiab ruaj khov, uas khaws cov qub raws li qhov xav tau ntawm cov tshiab.

Cov ntsiab lus keeb kwm: Cov lus qhia los ntawm Cov Hluav Taws Xob Yav Dhau Los

Txhawm rau nkag siab tias yog vim li cas cov tuam txhab qub tam sim no tau ua qhov tseem ceeb rau kev kho hluav taws kub, peb yuav tsum rov qab saib keeb kwm ntawm kev lag luam hluav taws kub. Cov kiv puag ncig kev lag luam tau tsim cov chaw tsim khoom loj ua nrog cov khoom siv hluav taws xob zoo li ntoo, tsis muaj kev tiv thaiv hlau, thiab hluav taws xob hluav taws xob. Cov qauv no tau tsim los rau kev ua haujlwm zoo, tsis muaj kev nyab xeeb, ua rau muaj kev puas tsuaj loj uas zoo li cov lej hluav taws xob niaj hnub no.

Ib qho piv txwv tsis zoo yog Lub Tuam Txhab Daim duab peb sab Shirtwaist Factory hluav taws hauv New York City xyoo 1911, qhov twg 146 tus neeg ua haujlwm tuag vim raug kaw, cov khoom siv hluav taws xob, thiab hluav taws kub tsis txaus. Qhov xwm txheej no tau txhawb nqa kev hloov pauv kev ua haujlwm thiab kev nyab xeeb thaum ntxov, tab sis nws siv sijhawm ntau xyoo rau cov kev cai dav dav kom tshwm sim. Nyob rau hauv nruab nrab-20th caug xyoo, hluav taws kub nyob rau hauv tshuaj nroj tsuag thiab warehouses qhia txog cov vulnerabilities ntawm steel-framed vaj tse, uas poob lub zog ntawm qhov kub thiab txias li 500 ° C (932 ° F). Yog tsis muaj kev tiv thaiv, hlau tuaj yeem buckle thiab vau nyob rau hauv feeb ntawm hluav taws kub.

Kev nrawm nrawm mus rau qhov xwm txheej tsis ntev los no: xyoo 2017 Grenfell Tower hluav taws hauv London, txawm hais tias nyob hauv tsev, tau hais txog qhov txaus ntshai ntawm cov khoom siv tsis tu ncua hauv cov tsev siab siab, cuam tshuam rau kev lag luam retrofits. Ib yam li ntawd, xyoo 2020 Beirut chaw nres nkoj tawg, cuam tshuam nrog ammonium nitrate hauv lub tsev khaws khoom qub, tau ceeb toom rau lub ntiaj teb ntawm kev pheej hmoo tawg hauv cov chaw lag luam laus. Cov xwm txheej no tau ua rau tsoomfwv thiab kev lag luam rov mus xyuas cov chaw qub qub, ntau yam uas yog yawm txiv nyob rau hauv cov cai qub. Retrofitting nrog hluav taws-resistant coatings hais txog cov keeb kwm saib xyuas, kom ntseeg tau tias cov qauv tsim ua ntej cov qauv niaj hnub tuaj yeem tiv taus cov kev hem thawj niaj hnub no.

Keeb kwm, fireproofing yog rudimentary-xav asbestos qhwv los yog gypsum boards yooj yim-tab sis kev nce qib hauv cov ntaub ntawv tshawb fawb tau ua cov txheej txheej rau kev daws teeb meem. Tsis zoo li invasive txoj kev uas yuav tsum tau dismantling, coatings yuav siv tau nrog tsawg heev cuam tshuam, khaws cia lub architectural kev ncaj ncees ntawm keeb kwm factories.

 

Txoj Cai Tsav Tsheb: Los ntawm Kev Ua Raws Cai rau Kev Ua Phem

Ib qho laj thawj tseem ceeb ntawm cov tuam tsev qub tau raug pleev xim nrog cov xim tiv thaiv hluav taws yog qhov hloov pauv ntawm cov cai hauv tsev thiab cov cai tswj hwm kev tiv thaiv hluav taws. Hauv Tebchaws Meskas, International Building Code (IBC) Tshooj 7 qhia txog qhov yuav tsum tau muaj rau kev tsim hluav taws kub-tiv taus, suav nrog cov tswv cuab hauv cov chaw ua haujlwm. Rau cov tsev laus, kev kho dua tshiab feem ntau yuav tsum tau ua thaum kho dua tshiab lossis hloov pauv hauv kev siv, raws li NFPA 101: Txoj Cai Kev Nyab Xeeb Lub Neej, uas hais txog kev tsim kho lub tsev hauv keeb kwm lossis cov qauv uas twb muaj lawm.

Txoj Cai Tswjfwm Kev Nyab Xeeb thiab Kev Noj Qab Haus Huv (OSHA) tus qauv 1926.150 hais txog kev tiv thaiv hluav taws hauv kev tsim kho thiab rhuav tshem, txuas mus rau kev lag luam rov ua dua tshiab uas muaj kev phom sij xws li cov tshuaj khaws cia ua kom muaj kev pheej hmoo. Hauv Tebchaws Europe, Txoj Cai Kev Tsim Kho Khoom Siv (CPR) thiab cov qauv hauv tebchaws xws li UK Txoj Cai Tswj Tsev B Tshooj B xav tau kev kho hluav taws kub-resistant rau steel ntsiab hauv factories. Piv txwv li, tom qab qhov kev nug Grenfell, UK tau yuam kom rov qab saib xyuas kev nyab xeeb hluav taws rau cov tsev uas muaj kev pheej hmoo siab, suav nrog kev lag luam.

Hauv Asia, cov tebchaws xws li Tuam Tshoj thiab Is Nrias teb tau ua lag luam sai sai thaum sib tw nrog cov txheej txheem qub txeeg qub teg. Tuam Tshoj tus GB 50016-2014 code yuav tsum tau fireproofing rau steel qauv nyob rau hauv factories, nrog retrofits tswj nyob rau hauv lub nroog retrofits tej yaam num. Ib yam li ntawd, Is Nrias teb National Building Code (NBC) 2016 tau teev cov txheej txheem hluav taws kub tiv thaiv rau cov tsev lag luam uas muaj ntau tshaj qhov siab lossis qhov chaw nyob.

Cov kev cai no tsis zoo li qub; lawv tau hloov kho nyob rau hauv teb rau cov kev pheej hmoo tshwm sim, xws li hluav taws kub hnyiab ntawm thaj chaw muaj kev lag luam vim kev hloov pauv huab cua. Hauv thaj chaw muaj hluav taws kub nyhiab xws li California, cov lus qhia rov qab los ntawm Headwaters Economics tus neeg tawm suab rau kev hloov kho hluav taws kub-resistant, suav nrog cov hluav taws kub-txheej txheej sab nrauv. Cov tuam txhab tuav pov hwm kuj tseem ua lub luag haujlwm, feem ntau xav tau kev tiv thaiv hluav taws kom tsim nyog tau txais kev pab them nqi lossis nqi qis dua. Kev tsis ua raws cai tuaj yeem ua rau raug nplua, kaw, lossis kev lav phib xaub thaum muaj xwm txheej, ua kom rov tsim kho cov cai tswj hwm tsis yog kev xaiv.

Kev loj hlob ntawm cov hluav taws-resistant coatings nyob rau hauv qub factories tshuav nqi ntau rau innovation nyob rau hauv cov ntaub ntawv engineering. Niaj hnub nimno coatings poob rau hauv ob pawg loj: intumescent thiab non-intumescent. Intumescent xim, zoo li cov los ntawm Firefree los yog Sherwin-Williams, o thaum raug tshav kub, ua ib tug tuab, insulating npuas uas tiv thaiv cov ntaub ntawv hauv qab. Cov no yog cov zoo tagnrho rau steel beams nyob rau hauv factories, muab txog li plaub teev ntawm hluav taws kub tsis tau ntxiv hnyav hnyav.

Cementitious coatings, txau zoo li plaster, muaj kev tiv thaiv zoo rau pob zeb thiab masonry hauv cov chaw qub qub. Lawv nqus cua sov thiab tso dej vapor, txias rau saum npoo. Cov kev txhim kho tsis ntev los no suav nrog cov qauv tsim hauv eco-phooj ywg siv bio-based polymers, txo qis cov organic tebchaw (VOCs) thiab ua raws li cov qauv tsev ntsuab xws li LEED.

Rau retrofitting, nyias-zaj duab xis intumescent varnishes yog tshwj xeeb tshaj yog nrov raws li lawv tuav lub zoo nkauj ntawm exposed cib los yog hlau nyob rau hauv repurposed factories. Cov tuam txhab xws li CharCoat tshwj xeeb hauv cov ntawv thov kev cuam tshuam tsawg heev uas tsis txhob ua haujlwm poob haujlwm. Cov qauv ntsuas, xws li ASTM E119 lossis UL 263, lees paub cov txheej txheem no rau kev ntsuas hluav taws tshwj xeeb, kom ntseeg tau tias lawv ua tau raws li kev tswj hwm.

Kev nce qib kuj hais txog kev laus: cov kev tshawb fawb qhia tau tias cov txheej txheem intumescent khaws cia tau zoo nyob rau ntau xyoo, txawm tias kev tshuaj xyuas ib ntus raug pom zoo. Hauv xyoo 2025, kev tsim kho tshiab xws li nanotechnology-txhim kho cov txheej txheem cog lus txawm tias muaj zog dua thiab ua haujlwm kub, ua kom rov qab tau nyiaj ntau dua.

 

Cov txiaj ntsig kev lag luam thiab kev nyab xeeb: Tshaj li kev ua raws cai

Thaum cov kev cai tsav cov qauv, cov txiaj ntsig ntawm cov hluav taws kub-resistant coatings txuas mus rau kev nyab xeeb thiab kev lag luam. Hais txog kev nyab xeeb, cov txheej txheem no txhim kho kev tiv thaiv hluav taws tsis zoo, sib cais hluav taws thiab tiv thaiv kev sib kis sai. Hauv cov chaw ua haujlwm nrog cov khoom siv phom sij, qhov no tuaj yeem txhais tau tias qhov sib txawv ntawm qhov xwm txheej uas muaj thiab muaj kev puas tsuaj loj. Cov xim pleev xim rau hluav taws txo qis cov cua sov tso tawm thiab tsim cov pa luam yeeb, txhim kho kev pom thiab huab cua zoo thaum khiav tawm.

Economically, retrofitting qub factories yog pheej yig dua li kev tsim kho tshiab. Ib txoj kev tshawb fawb los ntawm Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam thiab Kev Nyab Xeeb Hauv Tsev (IBHS) sau tseg tias cov txheej txheem hluav taws kub tsis zoo tuaj yeem txo cov hluav taws kub nyhiab hauv kev lag luam sab nrauv, uas yuav txuag tau ntau lab tus nqi kho. Cov nyiaj khaws cia ntev suav nrog cov nqi pov hwm qis dua thiab cov khoom muaj nqis ntxiv, tshwj xeeb tshaj yog rau cov chaw rov ua dua tshiab xws li lofts lossis cov chaw khaws ntaub ntawv.

Hauv Nyab Laj, piv txwv li, cov chaw tsim khoom siv cov tshuaj tua hluav taws uas muaj peev xwm tiv taus ntau txhiab degrees Celsius los tiv thaiv cov txheej txheem thav duab. Thoob plaws ntiaj teb, kev ua lag luam rau hluav taws-resistant txheej yog npaj kom loj hlob, tsav los ntawm kev lag luam retrofits. Aesthetically, cov coatings no yuav tinted los yog ntshiab, khaws cia cov nqaij qaib ntawm qub factories thaum ntxiv niaj hnub resilience.
