Halogen-dawb nplaim retardants ua lub luag haujlwm tseem ceeb hauv kev thauj mus los.Raws li kev tsim tsheb txuas ntxiv mus ntxiv thiab cov ntaub ntawv yas tau siv dav dua, cov khoom siv hluav taws xob hluav taws xob tau dhau los ua qhov tseem ceeb.Halogen-dawb nplaim taws retardant yog ib tug compound uas tsis muaj halogen hais xws li chlorine thiab bromine thiab muaj zoo heev nplaim retardant nyhuv.Hauv kev thauj mus los, cov ntaub ntawv yas tau siv dav, xws li cov khoom siv hauv tsheb, cov khoom siv hluav taws xob, thiab lwm yam. Txawm li cas los xij, cov yas feem ntau muaj cov khoom siv hluav taws xob tsis zoo thiab tuaj yeem ua rau hluav taws kub ceev.Yog li ntawd, cov nplaim retardants yuav tsum tau ntxiv los txhim kho cov nplaim retardant cov khoom ntawm cov yas thiab ua kom muaj kev nyab xeeb ntawm kev tsheb.Tshwj xeeb yuav tsum tau muab tso rau ammonium polyphosphate (APP).Raws li feem ntau siv halogen-dawb nplaim retardant, APP plays lub luag haujlwm tseem ceeb hauv cov nplaim hluav taws kub nyhiab.APP tuaj yeem siv tshuaj lom neeg nrog cov yas substrate los tsim cov txheej txheem carbonization ntom ntom, uas ua rau muaj txiaj ntsig zoo rau kev hloov pauv ntawm cov pa oxygen thiab cua sov, txo qis qhov kub thiab tiv thaiv kev sib kis ntawm hluav taws.Nyob rau tib lub sijhawm, cov khoom xws li phosphoric acid thiab dej vapor tso tawm los ntawm APP tuaj yeem cuam tshuam kev sib txuas thiab ntxiv txhim kho cov nplaim hluav taws xob ntawm cov yas.Los ntawm kev ntxiv cov nplaim hluav taws tsis muaj halogen xws li ammonium polyphosphate, cov ntaub ntawv yas hauv tsheb tuaj yeem tau txais cov nplaim hluav taws zoo thiab txo qhov tshwm sim ntawm hluav taws kub.Txuas ntxiv 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, daim ntawv thov kev cia siab ntawm cov nplaim hluav taws tsis muaj halogen yuav ua dav dua.
