Txhawm rau ua kom cov nplaim hluav taws kub hnyiab, nws yog qhov yuav tsum tau ntxiv cov nplaim hluav taws kub. Cov nplaim hluav taws kub hnyiab yog cov khoom siv ntxiv uas tuaj yeem txo qhov kev ua tau zoo ntawm cov yas. Lawv hloov cov txheej txheem combustion ntawm cov yas, maj mam sib kis ntawm cov nplaim taws, thiab txo cov cua sov tso tawm, yog li ua tiav cov nplaim hluav taws kub. Cov hauv qab no yuav qhia qee txoj hauv kev los ua cov nplaim hluav taws kub retardant.
Ntxiv cov nplaim hluav taws kub hnyiab: Inorganic nplaim retardants xa mus rau cov nplaim hluav taws uas muaj cov khoom siv tsis zoo xws li hlau, hlau oxides, thiab hlau ntsev. Cov nplaim hluav taws tsis zoo muaj xws li txhuas hydroxide, magnesium oxide, zinc oxide, thiab lwm yam. Cov nplaim hluav taws tsis zoo no tuaj yeem decompose ntawm qhov kub thiab txias kom tso dej vapor los yog oxides, nqus cua sov, tsim cov txheej txheem tiv thaiv, thiab tiv thaiv kev sib kis ntawm oxygen thiab cua sov, yog li ua tiav cov nplaim hluav taws kub.
Ntxiv cov nplaim hluav taws kub nyhiab: Cov nplaim hluav taws kub hnyiab xa mus rau cov nplaim hluav taws uas muaj cov organic sib txuas uas muaj cov ntsiab lus xws li nitrogen, phosphorus, thiab bromine. Cov nplaim hluav taws kub nyhiab muaj xws li ammonium polyphosphate, brominated nplaim retardants, thiab lwm yam. Cov nplaim hluav taws kub nyhiab no tuaj yeem decompose ntawm qhov kub thiab txias kom tso nitrogen, phosphorus oxides los yog bromides, tsim ib txheej carbon, thiab tiv thaiv kev sib kis ntawm oxygen thiab cua sov, yog li ua tiav cov nplaim hluav taws kub.
Kev kho deg: Los ntawm kev ua haujlwm tshwj xeeb ntawm cov yas saum npoo, cov nplaim hluav taws kub hnyiab tau tsim los tiv thaiv kev sib kis ntawm oxygen thiab cua sov, yog li ua tiav cov nplaim hluav taws kub. Cov txheej txheem kev kho saum npoo uas muaj xws li txau cov nplaim hluav taws, lub tshuab nqus tsev, thiab lwm yam.
Tus qauv tsim: Los ntawm kev hloov cov qauv molecular ntawm cov yas, nws muaj nws tus kheej cov nplaim hluav taws. Piv txwv li, los ntawm kev qhia cov pab pawg ua haujlwm uas muaj nitrogen, phosphorus thiab lwm yam khoom siv, kev hloov pauv ntawm cov saw hlau molecular hloov los txhim kho cov nplaim hluav taws xob ntawm cov yas.
Hauv kev siv cov tswv yim, cov txheej txheem hluav taws xob tsim nyog thiab cov nplaim hluav taws xob feem ntau raug xaiv raws li kev siv tshwj xeeb thiab cov kev xav tau ntawm cov yas los xyuas kom meej tias cov khoom yas muaj cov nplaim hluav taws zoo. Nyob rau tib lub sijhawm, yam xws li kev ua haujlwm ib puag ncig thiab toxicity ntawm cov nplaim hluav taws yuav tsum tau txiav txim siab kom muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig ntawm cov khoom yas.
Feem ntau, cov nplaim retardants feem ntau yog ntxiv los ua kom cov yas muaj cov nplaim hluav taws xob, thiab cov khoom siv hluav taws xob ntawm cov yas hloov pauv los ntawm cov nplaim hluav taws kub hnyiab, cov nplaim hluav taws kub nyhiab, cov nplaim hluav taws kub hnyiab, kev kho deg, cov qauv tsim thiab lwm txoj hauv kev kom ua tiav cov nplaim retardant. Thaum xaiv cov nplaim retardant txoj kev thiab nplaim retardants, yam xws li kev siv, ib puag ncig kev ua tau zoo, thiab kev nyab xeeb ntawm cov yas yuav tsum tau muab xam los xyuas kom meej tias cov khoom yas muaj cov nplaim retardant zoo.
