Yuav ua kom cov yas ua kom tsis txhob kub hnyiab, feem ntau yuav tsum ntxiv cov tshuaj tiv thaiv hluav taws. Cov tshuaj tiv thaiv hluav taws yog cov khoom ntxiv uas tuaj yeem txo qhov kev ua haujlwm ntawm cov yas. Lawv hloov cov txheej txheem kub hnyiab ntawm cov yas, qeeb qeeb qhov kev sib kis ntawm cov nplaim taws, thiab txo cov cua sov uas tso tawm, yog li ua tiav cov nyhuv tiv thaiv hluav taws. Cov hauv qab no yuav qhia qee txoj hauv kev siv los ua cov yas ua kom tsis txhob kub hnyiab.
Ntxiv cov tshuaj tua hluav taws inorganic: Cov tshuaj tua hluav taws inorganic yog hais txog cov tshuaj tua hluav taws uas muaj cov tshuaj inorganic xws li hlau, hlau oxides, thiab ntsev hlau. Cov tshuaj tua hluav taws inorganic feem ntau suav nrog txhuas hydroxide, magnesium oxide, zinc oxide, thiab lwm yam. Cov tshuaj tua hluav taws inorganic no tuaj yeem lwj thaum kub siab kom tso cov dej lossis oxides tawm, nqus cua sov, tsim ib txheej tiv thaiv, thiab tiv thaiv kev sib kis ntawm cov pa oxygen thiab cua sov, yog li ua tiav cov nyhuv tua hluav taws.
Ntxiv cov tshuaj tua hluav taws organic: Cov tshuaj tua hluav taws organic yog hais txog cov tshuaj tua hluav taws uas muaj cov organic compounds uas muaj cov ntsiab lus xws li nitrogen, phosphorus, thiab bromine. Cov tshuaj tua hluav taws organic feem ntau suav nrog ammonium polyphosphate, brominated flame retardants, thiab lwm yam. Cov tshuaj tua hluav taws organic no tuaj yeem lwj thaum kub siab kom tso nitrogen, phosphorus oxides lossis bromides, tsim cov txheej carbon, thiab tiv thaiv kev kis oxygen thiab cua sov, yog li ua tiav cov nyhuv tua hluav taws.
Kev kho qhov chaw: Los ntawm kev ua kev kho tshwj xeeb rau ntawm qhov chaw yas, ib daim zaj duab xis tiv thaiv hluav taws tau tsim los tiv thaiv kev sib kis ntawm cov pa oxygen thiab cua sov, yog li ua tiav cov nyhuv tiv thaiv hluav taws. Cov txheej txheem kho qhov chaw feem ntau suav nrog kev txau cov tshuaj tiv thaiv hluav taws, txheej nqus tsev, thiab lwm yam.
Kev tsim qauv: Los ntawm kev hloov cov qauv molecular ntawm cov yas, nws muaj nws cov yam ntxwv hluav taws kub. Piv txwv li, los ntawm kev qhia cov pab pawg ua haujlwm uas muaj nitrogen, phosphorus thiab lwm yam ntsiab lus, qhov kev teeb tsa ntawm cov saw hlau molecular raug hloov pauv los txhim kho cov yam ntxwv hluav taws kub ntawm cov yas.
Hauv kev siv ua haujlwm, cov txheej txheem tiv thaiv hluav taws xob thiab cov tshuaj tiv thaiv hluav taws xob feem ntau raug xaiv raws li kev siv tshwj xeeb thiab cov kev xav tau ntawm cov yas kom ntseeg tau tias cov khoom yas muaj cov khoom tiv thaiv hluav taws xob zoo. Tib lub sijhawm, cov yam xws li kev ua tau zoo ib puag ncig thiab kev lom ntawm cov tshuaj tiv thaiv hluav taws xob yuav tsum tau txiav txim siab kom ntseeg tau tias muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig ntawm cov khoom yas.
Feem ntau, cov tshuaj tua hluav taws feem ntau yog ntxiv rau kom cov yas muaj cov khoom tua hluav taws, thiab cov khoom sib xyaw ntawm cov yas raug hloov los ntawm cov tshuaj tua hluav taws inorganic, cov tshuaj tua hluav taws organic, kev kho qhov chaw, kev tsim qauv thiab lwm txoj hauv kev kom ua tiav cov nyhuv tua hluav taws. Thaum xaiv cov txheej txheem tua hluav taws thiab cov tshuaj tua hluav taws, cov yam xws li kev siv, kev ua tau zoo ib puag ncig, thiab kev nyab xeeb ntawm cov yas yuav tsum tau txiav txim siab kom ntseeg tau tias cov khoom yas muaj cov khoom tua hluav taws zoo.
