I. Tus Kws Saib Xyuas Tsev hauv Dubai uas khaws lub teeb rau hauv nws lub hnab ris
Tus kws tshuaj xyuas Dubai lub teeb sib zog tsis yog capricious. Nws yog qhov ua tau zoo los teb rau qhov teeb meem uas txhua tus neeg ua haujlwm hauv lub tuam tsev nyob rau hauv siab -qhov ceev hauv nroog txoj cai ntsib: qhov ntim ntawm cov ntaub ntawv tshiab nkag mus rau hauv kev tsim kho kev lag luam deb tshaj qhov muaj peev xwm ntawm cov chaw soj ntsuam los ntsuas lawv ua ntej lawv tshwm sim hauv cov lus qhia tshwj xeeb. Ib lub chaw tsim khoom tuaj yeem tsim, extrude, ua lag luam, thiab xa cov PVC- raws li phab ntsa vaj huam sib luag lossis qab nthab board sai dua li qhov chaw kuaj pom muaj peev xwm teem sijhawm, khiav, thiab tshaj tawm txog tag nrho ASTM E84 qhov kev sim. Qhov kev sim sib dua yog tus neeg soj ntsuam txoj hauv kev ntawm kev sib cais cov ntaub ntawv uas muaj txoj hauv kev dhau los ntawm kev xeem hluav taws los ntawm cov ntaub ntawv uas tsis muaj sijhawm.
Qhov teeb meem nws qhov teeb meem xeem qhov chaw nyob tsis yog hypothetical. Hauv ib lub tsev siab - nce siab, cov ntaub ntawv ua tiav sab hauv - qab nthab vaj huam sib luag, phab ntsa npog, hauv pem teb, luas thiab molding - txiav txim siab ceev npaum li cas hluav taws kub pib hauv ib chav tsev kis mus rau hauv txoj kev hauv tsev, mus rau hauv pem teb saum toj no, mus rau lub stairwell uas yog tib txoj kev tawm rau cov neeg nyob hauv pem teb. Cov qauv hlau thiab cov pob zeb ua hluav taws kub tiv thaiv lub tsev los ntawm kev tawg. Cov ntaub ntawv ua tiav sab hauv tiv thaiv cov neeg nyob ntawm cov pa taws thiab nplaim taws thaum lub sijhawm feeb uas tseem ceeb tshaj rau kev khiav tawm. Cov khoom uas kub hnyiab tau yooj yim thiab ua rau cov pa taws hnyav tuaj yeem ua rau muaj hluav taws kub hnyiab mus rau qhov tsis muaj sia nyob, tsis yog vim lub tsev ntog tab sis vim txoj kev tawm mus puv nrog cov pa taws ua ntej cov neeg nyob mus txog. Qhov hluav taws kub- kev nyab xeeb kev pab ntawm PVC-raws li cov khoom siv sab hauv tsis yog kev lag luam. Nws yog lub neej -kev nyab xeeb parameter uas lub tsev cai kho raws li qhov yuav tsum tau ua, tsis yog ib qho kev xaiv.
Kab lus no tshuaj xyuas qhov hluav taws kub hauv PVC cov ntaub ntawv hauv tsev los ntawm kev xav ntawm ib tus neeg uas xav tau qhov project pom zoo - tus kws tsim qauv xa cov khoom siv rau kev tshuaj xyuas, tus neeg cog lus uas nws cov ntaub ntawv tau raug ncaws tawm rov qab rau qhov hluav taws kub tsis txaus- cov ntaub ntawv xeem, tus tswv tsev uas tus neeg tuav pov hwm tus neeg tuav pov hwm tau nug txog cov nplaim hluav taws - nthuav tawm kev faib tawm sab hauv. Nws piav qhia tias qhov kev ntaus nqi txhais li cas, cov qauv kev sim siv rau cov khoom siv li cas, PVC piv rau cov khoom siv li cas, thiab qhov hluav taws kub raug cai li cas - daim ntawv qhia yuav tsum muaj.
II. Yuav ua li cas thaum PVC ntsib hluav taws - Chemistry Tsis muaj leej twg piav qhia hauv daim ntawv qhia
Qhov hluav taws kub cwj pwm ntawm PVC tsis yog ib tus lej. Nws yog ib ntus ntawm cov xwm txheej uas pib thaum cov khoom siv saum npoo kub ncav cuag li ob puas tsib caug mus rau peb puas degrees Celsius thiab xaus, yog tias cov khoom tsim tau zoo, nrog rau qhov hluav taws kub nws tus kheej - tua thiab cov txheej txheem ruaj khov tiv thaiv qhov seem ntawm cov khoom hauv qab. Kev nkag siab txog cov kab ke no yog qhov yuav tsum tau ua ua ntej kom nkag siab txog qhov ntsuas hluav taws kub thiab qhov nws tsis ua.
Qhov sib txawv ntawm qhov sib txawv ntawm PVC polymer saw nyob rau hauv nplaim taws. Theem ib tso tawm HCl thiab tsim ib tug conjugated polyene qauv. Theem ob tus ntoo khaub lig- txuas cov polyene rau hauv cov pa roj carbonaceous. Theem peb - sustained combustion - yog dab tsi chlorine chemistry yog tsim los tiv thaiv.
Thawj qhov tshwm sim thaum tshav kub mus txog PVC nto yog dehydrochlorination. Cov tshuaj chlorine atoms, khi rau cov pob txha polymer, raug tso tawm raws li hydrogen chloride gas. Cov txheej txheem no absorbs lub zog - nws cools cov khoom nto - thiab cov roj HCl tso rau hauv lub nplaim taws dilutes cov pa oxygen thiab combustible volatiles uas cov nplaim yuav tsum tau txhawb nws tus kheej. HCl molecule ua raws li ib tug radical scavenger, ntes cov reactive hydrogen thiab hydroxyl dawb radicals uas propagate lub combustion saw cov tshuaj tiv thaiv. Qhov no yog tib lub tswv yim los ntawm qhov uas halon tua hluav taws ua haujlwm, ua rau hauv cov khoom siv nws tus kheej.
Qhov thib ob uas tshwm sim yog char tsim. Tom qab cov tshuaj chlorine atoms tawm hauv cov pob txha polymer, cov roj carbon thiab hydrogen atoms uas tseem tshuav rov qab mus rau hauv ib qho kev sib txuas ntawm polyene qauv - ib ntu ntawm kev sib hloov ib zaug thiab ob npaug carbon - carbon bonds uas absorbs pom lub teeb thiab muab lub char nws cov xim tsaus nti. Cov qauv polyene no ces hla-txuas mus rau peb- cov pa roj carbon dimensional uas zaum ntawm qhov chaw ntawm cov khoom, insulating lub hauv paus PVC los ntawm tshav kub thiab maj mam tso tawm cov roj combustible ntxiv. Lub char yog ib qho kev tiv thaiv lub cev nrog rau cov tshuaj lom neeg.
Qhov thib peb - yam uas tsis tshwm sim nyob rau hauv zoo formulation rigid PVC - yog sustained combustion tom qab lub sab nraud nplaim raug tshem tawm. Kev sib xyaw ntawm HCl radical scavenging thiab char- txheej rwb thaiv tsev ua rau cov khoom siv tus kheej - tua. Tshem tawm cov nplaim taws, thiab qhov combustion nres. Lwm cov khoom siv yas tsis ua li no. Polyethylene, uas yog cov yas tsim ntau tshaj plaws nyob rau hauv lub ntiaj teb no, tsis muaj chlorine nyob rau hauv nws cov qauv thiab tsis muaj nyob rau hauv hluav taws kub retardancy. Nws kub hnyiab nrog ib tug kub, huv si nplaim taws thiab drips burning molten polymer raws li nws hlawv, kis hluav taws mus rau tej chaw hauv qab no. Polypropylene coj zoo ib yam. Polystyrene kub hnyiab nrog cov pa luam yeeb dub hnyav thiab tseem drips. PVC cov ntsiab lus chlorine, kev lav phib xaub uas cov khoom siv thuam hais hauv kev sib tham txog kev tua hluav taws thiab pov tseg, yog qhov zoo tshaj plaws uas ua rau nws tsim nyog rau lub tsev sab hauv qhov hluav taws kub tswj kev xaiv cov khoom siv.
Qhov no tsis yog hais tias nruj PVC yog fireproof. Nws tsis yog. Thaum qhov kub txaus txaus thiab nrog cov nplaim taws sab nraud, PVC yuav kub hnyiab, thiab cov khoom siv hluav taws xob muaj xws li carbon monoxide, hydrogen chloride, thiab ntau yam organic tebchaw. Tsis muaj cov organic polymer tiv thaiv hluav taws. Cov lus nug uas qhov ntsuas hluav taws tsis teb tsis yog "cov khoom siv no puas yuav hlawv" tab sis "cov khoom siv no coj li cas hauv hluav taws piv rau lwm txoj hauv kev, thiab tus cwj pwm ntawd puas ua tau raws li lub tsev tsim cai rau daim ntawv thov." PVC cov lus teb rau lo lus nug no, ntawm cov khoom tsim tau zoo nrog daim ntawv tshaj tawm kev xeem raug cai, feem ntau yog Class A lossis B1 - qhov siab tshaj lossis thib ob-kev faib hluav taws kub siab tshaj plaws muaj rau cov khoom siv sab hauv.

Tus qauv tau hloov. Lub nra ntawm cov ntaub ntawv pov thawj yog nyob ntawm cov chaw tsim khoom.
5. Sab hauv haum- tawm ntawm cov chaw kho mob thiab kev kawm.Cov tsev kho mob thiab tsev kawm ntawv tsim hluav taws xob- cov kev cai nyab xeeb uas dhau mus dhau qhov tsawg kawg nkaus ntawm lub tsev vim tias cov neeg nyob hauv lub tsev no tsis tuaj yeem khiav tawm sai sai - cov neeg mob hauv txaj hauv tsev kho mob, cov menyuam yaus hauv chav kawm, cov neeg laus hauv cov chaw zov me nyuam. Cov khoom siv ua tiav sab hauv hauv cov chaw nyob no yuav tsum txo cov nplaim taws thiab cov pa luam yeeb tsawg, thiab cov pa luam yeeb - cov yam ntxwv ntawm cov khoom siv hluav taws xob tau raug tshuaj xyuas ntau dua li lwm hom tsev. PVC-raws li cov phab ntsa vaj huam sib luag, qab nthab vaj huam sib luag, thiab hauv pem teb uas tau teev tseg rau kev kho mob thiab kev kawm yuav tsum nqa cov ntaub ntawv kuaj hluav taws uas tsis yog FSI thiab SDI nkaus xwb tab sis kuj tseem muaj kev sib tsoo tshwj xeeb- cov ntaub ntawv cov khoom lag luam uas cov neeg siv khoom xav tau ua ib feem ntawm lawv cov kev pheej hmoo sab hauv- cov txheej txheem ntsuas.
Cov khoom siv hluav taws kub tsis yog cov khoom zoo li qub. Nws yog ib qho kev ntsuam xyuas uas siv rau cov khoom tsim tshwj xeeb ntawm cov tuab tshwj xeeb hauv kev teeb tsa tshwj xeeb. PVC ua npuas ncauj board uas ua tiav Class A ntawm rau millimeters thickness yuav tsis ua tiav Class A ntawm peb millimeters, vim hais tias cov qauv thinner muaj tsawg thermal mass kom nqus cua sov ua ntej mus txog qhov kub thiab txias. Ib yam khoom kuaj hauv qab nthab-mount configuration yuav coj txawv txawv thaum kuaj nyob rau hauv ib phab ntsa-mount configuration vim hais tias cov nplaim taws- kis dynamics txawv thaum tus qauv yog kab rov tav piv rau ntsug. Tus specifier lub luag hauj lwm yog los xyuas kom meej tias daim ntawv ntsuam xyuas sib tw cov khoom, lub thickness, thiab lub installation configuration tau teev. Tus kws tshuaj xyuas Dubai lub teeb pom kev zoo, rau tag nrho nws qhov tsis raug cai, khaws qhov tseeb tseem ceeb: qhov ntsuas hluav taws tsis muaj nuj nqis tshwj tsis yog tias nws siv rau cov khoom tshwj xeeb hauv cov khoom tshwj xeeb txhais tes, tsis yog rau cov khoom sib txawv los ntawm tib lub chaw tsim khoom uas tau tshwm sim dhau los xeem kaum xyoo dhau los.
