Qee cov nplaim hluav taws kub hnyiab tuaj yeem ua rau cov nplaim hluav taws zoo ntawm qhov sib ntxiv qis, thaum lwm tus yuav xav tau ntau dua ntxiv. Piv txwv li, phosphorus-based nplaim retardants feem ntau tuaj yeem ua tiav cov nplaim hluav taws zoo dua ntawm qhov qis ntxiv, thaum qee cov nplaim hluav taws xob tsis zoo yuav xav tau ntau dua ntxiv kom tau raws li cov nplaim hluav taws kub. Thaum xaiv cov khoom siv tua hluav taws tsis siv neeg, qhov cuam tshuam ntawm lawv cov nyiaj ntxiv ntawm kev ua haujlwm thiab tus nqi ntawm cov nplaum yuav tsum tau txiav txim siab. Yog tias cov nplaim hluav taws kub hnyiab tau kim heev tab sis muaj qhov sib ntxiv qis thiab tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov nplaum nplaum, los ntawm kev xav ntawm tag nrho cov nqi, nws tseem yuav yog qhov kev xaiv tsim nyog.
3. Cov Txheej Txheem Ua: Cov txheej txheem tsim cov khoom siv hluav taws xob tsis siv neeg tua hluav taws kuj tseem cuam tshuam rau lawv cov nqi. Qee cov txheej txheem ntau lawm yuav ua rau tus nqi ntau lawm ntawm cov ntaub ntawv, thaum qee cov txheej txheem tsim khoom yooj yim muaj tus nqi qis dua. Thaum xaiv cov khoom siv tua hluav taws tsis siv neeg, cov khoom siv nrog cov txheej txheem tsim khoom yooj yim thiab tus nqi qis tuaj yeem txiav txim siab. Tsis tas li ntawd, cov nqi tsim khoom ntawm cov khoom siv tua hluav taws tsis siv neeg tuaj yeem raug txo los ntawm kev ua kom zoo ntawm cov txheej txheem ntau lawm. Piv txwv li, thaum npaj cov nplaim-retardant adhesives los ntawm txoj kev blending, dispersion ntawm nplaim retardant nyob rau hauv cov nplaum yuav txhim kho los ntawm optimizing cov txheej txheem blending, yog li txo qhov sib ntxiv ntawm cov nplaim hluav taws kub thiab txo cov nqi tsim khoom.
