Cov Khoom Siv Hluav Taws Xob Tsis Siv Neeg Hluav Taws Xob yog "cov neeg tua hluav taws tsis pom" uas tiv thaiv lawv lub neej thiab khoom
Hauv lub ntiaj teb uas hluav taws kub nyhiab ua rau muaj kev hem thawj tsis tu ncua rau lub neej, khoom vaj khoom tsev, thiab kev tsim kho vaj tse, cov khoom siv hluav taws kub tsis siv neeg tau tshwm sim los ua tus phab ej uas tsis pom zoo, tau txais cov moniker "cov neeg tua hluav taws tsis pom." Cov ntaub ntawv qib siab no yog tsim los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tua hluav taws. Muab tso rau hauv cov tsev, tsheb, lossis cov khoom siv niaj hnub, lawv ntsiag to sawv ntsug, npaj kom muaj hluav taws kub hnyiab ntawm thawj lub cim ntawm kev phom sij. Los ntawm intumescent txheej uas swell mus rau insulate cov qauv mus rau nws tus kheej-extinguishing polymers uas nres combustion, cov ntaub ntawv no yog revolutionizing hluav taws kev nyab xeeb los ntawm kev tiv thaiv me me sparks los ua kev puas tsuaj blazes.
Qhov tseem ceeb ntawm tsis siv neeg tua hluav taws cov ntaub ntawv tsis tuaj yeem overstated. Hauv Tebchaws Meskas ib leeg, National Fire Protection Association (NFPA) tau tshaj tawm tias kev tua hluav taws ua rau ntau dua $ 14 nphom hauv vaj tse puas tsuaj txhua xyoo, nrog ntau txhiab tus neeg tuag lossis raug mob. Thoob plaws ntiaj teb, cov xwm txheej ntsig txog hluav taws ua rau muaj kev lag luam thiab ua rau cov zej zog puas tsuaj. Ib txwm siv hluav taws tua hluav taws xws li cov tshuab tua hluav taws thiab cov tua hluav taws, thaum ua haujlwm zoo, cia siab rau kev ua kom muaj zog thiab kho. Nyob rau hauv sib piv, tsis siv neeg supposed cov ntaub ntawv yog proactive, integrating seamlessly rau hauv ib puag ncig los muab passive tiv thaiv. Kab lus no tshawb txog keeb kwm, kev tshawb fawb, hom, kev siv, cov ntaub ntawv tshawb fawb, cov txiaj ntsig, cov kev sib tw, thiab cov qauv yav tom ntej ntawm cov ntaub ntawv zoo kawg li no, qhia txog lawv lub luag haujlwm tseem ceeb hauv kev tiv thaiv lub neej thiab vaj tse.
Keeb kwm ntawm Cov Khoom Siv Hluav Taws Xob Tsis Siv Neeg Hluav Taws Xob
Txoj kev taug kev ntawm cov ntaub ntawv tua hluav taws tau pib ntau pua xyoo dhau los nrog kev sim ua kom cov khoom siv hluav taws kub-resistant. Thaum ntxov li 400 BC, kev vam meej thaum ub tau kho ntoo nrog alum kom txo tau cov nplaim taws. Lub Great Hluav Taws Xob ntawm London xyoo 1666 yog qhov hloov pauv, nthuav tawm qhov xav tau kev tiv thaiv hluav taws zoo dua thiab ua rau muaj kev hloov tshiab tshiab hauv kev kho hluav taws kub. Txawm li cas los xij, kev txhim kho cov khoom siv hluav taws xob tsis siv neeg niaj hnub no tau coj los ua qauv hauv xyoo pua 20th, tau tsav los ntawm kev nce qib hauv chemistry thiab engineering.
Intumescent coatings, uas nthuav dav hauv qab cua sov los tsim kev tiv thaiv char, tau tshawb nrhiav thawj zaug hauv xyoo 1930s rau kev siv ntoo tab sis tau txais kev sib tw hauv xyoo 1970 los tiv thaiv cov qauv hlau hauv cov tsev siab. Los ntawm xyoo 1980s, cov coatings no tau dhau los ua ib qho tseem ceeb hauv cov cai hauv tsev, ua kom muaj kev ncaj ncees thaum muaj hluav taws kub. Raws li qhov tshwm sim, nws tus kheej tua cov polymers tau tshwm sim, nrog cov nplaim hluav taws xob ntxiv xws li halogens thiab phosphorus tebchaw ua rau cov khoom siv kom tsis txhob hlawv thaum lub qhov hluav taws xob raug tshem tawm. Xyoo 1990s pom qhov nce ntawm ib puag ncig tus phooj ywg dej-raws li intumescents, txo cov volatile organic compounds (VOCs) thaum tswj kev ua tau zoo.
Regulatory kev nce qib, xws li UL thiab ASTM cov qauv, cov txheej txheem kuaj cov txheej txheem, ua kom ntseeg tau thiab ua haujlwm tau zoo. Cov xwm txheej ntxhov siab, zoo li 2017 Grenfell Tower hluav taws, qhia txog qhov tseem ceeb ntawm kev tiv thaiv hluav taws, ua rau kev tshawb nrhiav thiab kev saws me nyuam. Niaj hnub no, cov khoom siv hluav taws xob tsis siv neeg yog lub hauv paus ntawm kev nyab xeeb hluav taws niaj hnub, tsim nyob rau ntau xyoo ntawm kev tsim kho tshiab los tsim kom muaj kev nyab xeeb dua.
Lub Hauv Paus No. Tsis Siv Neeg Hluav Taws Xob Cov Khoom Siv Hluav Taws Xob
Qhov ua tau zoo ntawm cov khoom siv hluav taws kub tsis siv neeg yog nyob rau hauv lawv lub peev xwm los teb autonomously rau cua sov los yog nplaim taws los ntawm cov khoom siv tshuaj lom neeg thiab lub cev. Intumescent coatings, piv txwv li, yog formulated nrog ib tug trio ntawm lub ntsiab Cheebtsam: ib tug acid qhov chaw (xws li, ammonium polyphosphate), ib tug carbon qhov chaw (xws li, pentaerythritol), thiab ib tug tshuab (xws li, melamine). Thaum raug kub ib ncig ntawm 350-400 ° F, cov khoom no ua rau muaj kev cuam tshuam. Cov txheej txheej melts, tso tawm cov pa roj uas ua rau nws nthuav mus txog 100 npaug ntawm nws qhov qub thickness, thiab solidifies rau hauv ib qho ntxeem tau, insulating char. Cov char no ua rau lub thermal barrier, ua kom kub hloov mus rau hauv lub hauv paus substrate - txawm steel, ntoo, los yog pob zeb - tiv thaiv ignition los yog cov yam ntxwv tsis ua hauj lwm.
Cov txheej txheem yog peb zaug: lub binder melts, gases ua rau expansion, thiab cov char solidifies, tso cov roj uas tsis yog-flammable rau dilute oxygen thiab tshaib plab hluav taws. Kev ntsuas hluav taws, xws li cov hauv qab ASTM E119, ntsuas kev ua tau zoo, nrog rau kev ntsuas ob-teev qhia tias cov khoom tuaj yeem tswj hwm kev ncaj ncees rau lub sijhawm ntawd raws li tus qauv hluav taws kub.
Self-extinguishing polymers, xws li nplaim taws-retardant polyamides los yog polycarbonates, muab cov additives uas cuam tshuam lub combustion voj voog. Cov additives no, xws li brominated compounds los yog phosphorus-raws li retardants, tsim ib txheej char los yog tso tawm radical scavengers uas quench nplaim taws, xyuas kom cov khoom tsis hlawv thaum tshav kub qhov chaw raug tshem tawm. Muab faib raws li UL94 cov qauv (xws li, V-0 rau kev tua tus kheej sai), cov polymers no yog tsim los tiv thaiv kev ya raws thiab nplaim taws.
Lwm cov khoom siv tshuaj tua kab mob, xws li cov tshuaj ua npuas dej lossis cov roj tso tawm tsis zoo, ua haujlwm los ntawm kev tua hluav taws lossis cuam tshuam cov tshuaj tiv thaiv. Piv txwv li, ua npuas ncauj concentrates tsim ib daim pam tshaj cov kua nplaum, thaum cov tshuaj qhuav xws li sodium bicarbonate tawg daim duab peb sab hluav taws (roj, oxygen, cua sov).
Cov txheej txheem no ua kom tsis siv neeg ua haujlwm, ua cov ntaub ntawv no muaj tseeb "cov neeg tua hluav taws tsis pom" uas ua nrawm thiab txiav txim siab.
