Cov nplaim hluav taws kub hnyiab yog cov khoom siv tseem ceeb siv hauv ntau yam ntaub ntawv, tshwj xeeb yog cov yas, kom txo tau cov nplaim taws thiab txhim kho kev nyab xeeb ntawm hluav taws. Raws li qhov kev thov rau cov khoom muaj kev nyab xeeb nce, kev txhim kho thiab kev siv cov nplaim hluav taws kub hnyiab tau hloov zuj zus. Kab lus no tshawb txog ntau yam ntawm cov nplaim hluav taws xob uas feem ntau siv hauv cov yas, lawv cov txheej txheem ntawm kev ua, thiab lawv qhov cuam tshuam ib puag ncig.
Halogenated nplaim retardants yog ib qho ntawm feem ntau siv hauv kev lag luam plastics. Cov tshuaj no muaj bromine lossis chlorine thiab muaj txiaj ntsig zoo hauv kev cuam tshuam cov txheej txheem combustion. Thaum raug tshav kub, lawv tso tawm halogen atoms uas hnov mob nrog dawb radicals nyob rau hauv cov nplaim taws, zoo quenching hluav taws. Piv txwv xws li tetrabromobisphenol A (TBBPA) thiab polybrominated diphenyl ethers (PBDEs). Thaum muaj txiaj ntsig zoo, kev txhawj xeeb txog lawv qhov kev pheej hmoo ib puag ncig thiab kev pheej hmoo kev noj qab haus huv tau ua rau muaj kev tshuaj xyuas ntau ntxiv thiab kev tswj hwm.
Phosphorus-raws li nplaim taws retardants tau txais koob meej vim lawv cov txiaj ntsig thiab kev cuam tshuam ib puag ncig qis dua piv rau cov kev xaiv halogenated. Cov tebchaw no tuaj yeem muab faib ua ob hom tseem ceeb: reactive thiab additive. Reactive phosphorus nplaim hluav taws retardants chemically bond nrog lub polymer thaum lub sij hawm tsim cov txheej txheem, thaum additive hom tseem nyob rau hauv lub cev sib tov nyob rau hauv cov yas. Piv txwv xws li triphenyl phosphate (TPP) thiab ammonium polyphosphate (APP). Lawv ua hauj lwm los ntawm kev txhawb char tsim, uas ua raws li ib tug barrier rau cua sov thiab oxygen, yog li ntawd slows down combustion.
Inorganic nplaim retardants, xws li txhuas hydroxide thiab magnesium hydroxide, yog non-toxic thiab environmentally friendly lwm. Cov tebchaw no tso dej vapor thaum cua sov, uas ua rau cov khoom txias thiab dilutes flammable gases. Lawv feem ntau siv rau hauv cov ntawv thov uas kev nyab xeeb yog qhov tseem ceeb, xws li hauv cov khoom siv hluav taws xob thiab hluav taws xob. Thaum lawv tsis tshua muaj txiaj ntsig ntawm qhov kub qis dua piv rau halogenated lossis phosphorus-based retardants, lawv cov ntaub ntawv kev nyab xeeb ua rau lawv xaiv ntau yam kev siv.
Intumescent nplaim retardants yog tshwj xeeb nyob rau hauv uas lawv nthuav thaum raug tshav kub, tsim ib tug tiv thaiv char txheej uas insulates lub hauv paus khoom ntawm nplaim taws. Hom nplaim retardant no feem ntau muaj kev sib xyaw ntawm cov pa roj carbon monoxide, cov kua qaub, thiab lub tshuab tshuab. Thaum rhuab, cov kua qaub catalyzes cov pa roj carbon monoxide los tsim cov char, thaum lub tshuab tshuab tsim cov pa npuas uas nthuav cov char txheej. Cov txheej txheem no muab kev tiv thaiv hluav taws zoo heev thiab feem ntau siv rau hauv cov coatings thiab cov yas hloov tau yooj yim.
Thaum cov nplaim hluav taws kub hnyiab ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev nyab xeeb hluav taws, lawv siv ua rau muaj kev txhawj xeeb txog ib puag ncig thiab kev noj qab haus huv. Ntau cov nplaim hluav taws halogenated tau txuas rau cov teebmeem kev noj qab haus huv, suav nrog kev cuam tshuam ntawm endocrine thiab teeb meem kev loj hlob. Yog li ntawd, lub koom haum tswj hwm tau nce ntxiv txwv lawv txoj kev siv. Piv txwv li, phosphorus thiab inorganic nplaim retardants feem ntau suav hais tias muaj kev nyab xeeb dua lwm txoj hauv kev, txawm hais tias kev tshawb fawb txuas ntxiv yog tsim nyog kom nkag siab txog lawv cov kev cuam tshuam mus sij hawm ntev.
Kev xaiv cov nplaim hluav taws kub nyhiab hauv cov yas yog cuam tshuam los ntawm ntau yam, suav nrog kev ua tau zoo, kev nyab xeeb, thiab kev cuam tshuam ib puag ncig. Raws li kev tswj hwm nruj thiab kev paub txog cov neeg siv khoom loj hlob tuaj, kev lag luam zoo li yuav txuas ntxiv hloov mus rau kev nyab xeeb dua, muaj kev nyab xeeb dua cov nplaim hluav taws kub. Kev nkag siab txog ntau yam ntawm cov nplaim hluav taws kub thiab lawv cov txheej txheem yog qhov tseem ceeb rau cov tuam txhab, cov neeg siv khoom, thiab cov neeg tsim cai lij choj ib yam nkaus hauv kev tshawb nrhiav cov ntaub ntawv zoo dua.
