Cov tshuaj tua hluav taws uas tsis muaj halogen ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv hluav taws ntawm cov ntaub.

Cov tshuaj tua hluav taws uas tsis muaj halogen ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv hluav taws ntawm cov ntaub. Thaum tib neeg paub txog kev tiv thaiv ib puag ncig ntau ntxiv, cov tshuaj tua hluav taws uas muaj halogen ib txwm muaj ntau zuj zus. Cov tshuaj tua hluav taws uas tsis muaj halogen yog cov tshuaj uas tsis muaj cov khoom halogen xws li chlorine thiab bromine. Lawv siv muaj ntau yam zoo hauv kev tiv thaiv hluav taws ntawm cov ntaub. Tam sim no, ntau cov tshuaj tua hluav taws uas tsis muaj halogen siv dav hauv kev tiv thaiv hluav taws ntawm cov ntaub. Piv txwv li: ammonium polyphosphate (APP), copolycyanurate (CP), aluminium hydroxide (ATH), nitrogen-phosphorus flame retardant (HNF), thiab lwm yam. Cov tshuaj tua hluav taws uas tsis muaj halogen no tsis tsuas yog ua rau qeeb qeeb ntawm kev hlawv ntawm cov ntaub xwb, tab sis kuj tsim cov tshuaj lom neeg uas tiv thaiv kev hlawv ntawm qhov kub siab, yog li tiv thaiv kev kis hluav taws. Yuav tsum tau muab qhov tseem ceeb rau ammonium polyphosphate (APP). Raws li cov tshuaj tua hluav taws uas tsis muaj halogen feem ntau siv, APP muaj peev xwm tiv thaiv hluav taws zoo heev rau cov ntaub. Hauv cov ntaub, APP tuaj yeem nqus cua sov thiab lwj ua ib txheej phosphate uas tiv thaiv kev hloov pauv ntawm oxygen thiab cua sov thiab tiv thaiv kev kis hluav taws. Tib lub sijhawm, APP kuj tseem tuaj yeem txhawb cov tshuaj carbonization ntawm cov ntaub thiab tsim cov txheej carbon ntom ntom, txhim kho kev ua haujlwm ntawm cov ntaub. Qhov no ua rau APP yog ib qho ntawm cov tshuaj tua hluav taws halogen-free nrov tshaj plaws hauv thaj chaw ntawm cov ntaub nplaim taws retardancy. Hauv kev xaus, cov tshuaj tua hluav taws halogen-free ua lub luag haujlwm tseem ceeb hauv thaj chaw ntawm cov ntaub nplaim taws retardancy. Los ntawm kev siv cov tshuaj tua hluav taws halogen-free xws li ammonium polyphosphate, cov ntaub tuaj yeem ua tiav cov teebmeem nplaim taws retardant zoo thiab txhim kho kev nyab xeeb hluav taws. Nrog rau kev nce qib ntawm thev naus laus zis, nws ntseeg tau tias cov tshuaj tua hluav taws halogen-free yuav ua lub luag haujlwm tseem ceeb hauv cov ntaub nplaim taws retardancy yav tom ntej.
