Cov yas uas tiv taus hluav taws tau tsim los kom tiv taus kev kub hnyiab, qeeb hluav taws kis mus, thiab txo cov pa luam yeeb, ua rau lawv tseem ceeb rau cov ntawv thov uas kev nyab xeeb hluav taws tseem ceeb heev. Cov yas no muaj cov khoom ntxiv xws li cov tshuaj halogenated (piv txwv li, bromine), cov neeg sawv cev phosphorus, lossis cov khoom inorganic xws li txhuas hydroxide. Thaum raug cua sov, cov khoom ntxiv no tso tawm cov pa roj uas tiv thaiv hluav taws, tsim cov txheej char tiv thaiv, lossis nqus cua sov kom qeeb kev kub hnyiab.
Siv dav hauv kev lag luam hluav taws xob, kev tsim kho, thiab kev lag luam tsheb, cov yas uas tiv taus hluav taws kub ua tau raws li cov qauv kev nyab xeeb nruj (piv txwv li, UL94). Piv txwv li, lawv tiv thaiv cov thawv hluav taws xob los ntawm hluav taws luv luv thiab txhim kho kev tiv thaiv hluav taws ntawm cov khoom siv hauv tsev. Txawm li cas los xij, cov khoom ntxiv halogenated ib txwm ua rau muaj kev txhawj xeeb txog ib puag ncig vim muaj cov pa phem, ua rau muaj kev xav tau rau lwm txoj hauv kev zoo rau ib puag ncig xws li cov khoom sib xyaw nitrogen-phosphorus lossis cov tshuaj minerals.
Cov kev tsim kho tshiab tsis ntev los no tsom mus rau nanotechnology thiab cov khoom siv bio-based. Nanoclays lossis carbon nanotubes txhim kho kev tiv thaiv hluav taws yam tsis muaj kev cuam tshuam rau cov khoom siv kho tshuab, thaum cov tshuaj lignin-derived muab cov kev xaiv ruaj khov. Cov teeb meem tseem nyob hauv kev sib npaug ntawm kev tiv thaiv hluav taws nrog kev ywj pheej ntawm cov khoom siv thiab kev siv nyiaj tsawg.
Thaum cov kev cai lij choj nruj dua thiab cov lag luam muab qhov tseem ceeb rau kev ruaj khov, yav tom ntej ntawm cov yas uas tsis kub hnyiab yog nyob rau hauv cov qauv tsis muaj tshuaj lom, ua haujlwm tau zoo uas ua raws li cov ntsiab cai ntawm kev lag luam ncig. Cov kev nce qib no ua kom ntseeg tau tias muaj kev nyab xeeb dua, cov ntaub ntawv ntsuab dua rau cov ntawv thov niaj hnub no.
