Cov tshuaj tua hluav taws uas tsis muaj halogen ua lub luag haujlwm tseem ceeb hauv kev thauj mus los. Thaum kev tsim tsheb txuas ntxiv mus thiab cov khoom siv yas siv dav dua, cov khoom tua hluav taws kuj tseem ceeb heev. Cov tshuaj tua hluav taws uas tsis muaj halogen yog cov khoom uas tsis muaj halogen xws li chlorine thiab bromine thiab muaj cov nyhuv tua hluav taws zoo heev. Hauv kev thauj mus los, cov khoom siv yas siv dav, xws li cov khoom siv sab hauv tsheb, cov khoom siv hluav taws xob, thiab lwm yam. Txawm li cas los xij, cov yas feem ntau muaj cov khoom hlawv tsis zoo thiab tuaj yeem ua rau muaj hluav taws kub. Yog li ntawd, yuav tsum ntxiv cov tshuaj tua hluav taws kom txhim kho cov khoom tua hluav taws ntawm cov yas thiab xyuas kom muaj kev nyab xeeb ntawm tsheb. Yuav tsum muaj kev tsom mus rau ammonium polyphosphate (APP). Raws li cov tshuaj tua hluav taws uas tsis muaj halogen feem ntau siv, APP ua lub luag haujlwm tseem ceeb hauv kev tua hluav taws yas. APP tuaj yeem sib xyaw nrog cov yas substrate los tsim cov txheej carbonization ntom ntom, uas ua rau cov pa oxygen thiab cua sov hloov pauv tau zoo, ua rau qeeb qeeb ntawm kev hlawv thiab tiv thaiv kev kis hluav taws. Tib lub sijhawm, cov tshuaj xws li phosphoric acid thiab cov pa dej uas APP tso tawm kuj tseem tuaj yeem tiv thaiv kev sib xyaw thiab txhim kho cov khoom tua hluav taws ntawm cov yas. Los ntawm kev ntxiv cov tshuaj tua hluav taws uas tsis muaj halogen xws li ammonium polyphosphate, cov khoom siv yas hauv tsheb tuaj yeem tau txais cov khoom zoo tua hluav taws thiab txo qhov tshwm sim ntawm kev sib tsoo hluav taws. Txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm kev thauj mus los. Raws li qhov yuav tsum tau ua rau kev tiv thaiv ib puag ncig nce ntxiv, kev siv cov tshuaj tua hluav taws uas tsis muaj halogen yuav dav dua.
