Cov tshuaj tiv thaiv hluav taws yog cov khoom siv tseem ceeb uas siv rau hauv ntau yam khoom siv, tshwj xeeb tshaj yog cov yas, los txo qhov kub hnyiab thiab txhim kho kev nyab xeeb ntawm hluav taws. Raws li qhov kev thov rau cov khoom muaj kev nyab xeeb dua ntxiv, kev tsim kho thiab kev siv cov tshuaj tiv thaiv hluav taws tau hloov pauv ntau heev. Tsab xov xwm no tshawb nrhiav ntau hom tshuaj tiv thaiv hluav taws uas feem ntau siv rau hauv cov yas, lawv cov txheej txheem ua haujlwm, thiab lawv cov teeb meem ib puag ncig.
Cov tshuaj halogenated flame retardants yog cov tshuaj siv dav tshaj plaws hauv kev lag luam yas. Cov tshuaj no muaj bromine lossis chlorine thiab ua haujlwm tau zoo hauv kev cuam tshuam cov txheej txheem combustion. Thaum raug cua sov, lawv tso tawm cov halogen atoms uas cuam tshuam nrog cov free radicals hauv nplaim taws, ua rau tua hluav taws tau zoo. Piv txwv li feem ntau suav nrog tetrabromobisphenol A (TBBPA) thiab polybrominated diphenyl ethers (PBDEs). Txawm hais tias ua haujlwm tau zoo, kev txhawj xeeb txog lawv qhov kev nyob ntev ib puag ncig thiab kev pheej hmoo kev noj qab haus huv tau ua rau muaj kev tshuaj xyuas thiab kev tswj hwm ntau dua.
Cov tshuaj tua hluav taws uas muaj phosphorus ua tau ntau zuj zus vim lawv ua haujlwm tau zoo thiab tsis cuam tshuam rau ib puag ncig piv rau cov tshuaj halogenated. Cov tshuaj no muaj ob hom: reactive thiab additive. Cov tshuaj tua hluav taws uas muaj phosphorus ua tau ntau yam sib txuas nrog cov polymer thaum lub sijhawm tsim khoom, thaum cov tshuaj additive tseem sib xyaw ua ke hauv cov yas. Piv txwv li, triphenyl phosphate (TPP) thiab ammonium polyphosphate (APP). Lawv ua haujlwm los ntawm kev txhawb nqa kev tsim cov char, uas ua rau muaj cua sov thiab oxygen, yog li ua rau kev sib xyaw qeeb.
Cov tshuaj tiv thaiv hluav taws uas tsis muaj zog, xws li txhuas hydroxide thiab magnesium hydroxide, yog cov tshuaj uas tsis muaj tshuaj lom thiab tsis ua rau ib puag ncig puas tsuaj. Cov tshuaj no tso cov dej tawm thaum raug cua sov, uas ua rau cov khoom txias thiab ua rau cov pa roj uas yooj yim hlawv tawm. Lawv feem ntau siv rau hauv cov ntawv thov uas muaj kev nyab xeeb tseem ceeb, xws li hauv cov khoom siv hluav taws xob thiab khoom siv hluav taws xob. Txawm hais tias lawv tsis tshua muaj txiaj ntsig ntawm qhov kub qis dua piv rau cov tshuaj halogenated lossis phosphorus-based retardants, lawv cov qauv kev nyab xeeb ua rau lawv yog qhov kev xaiv zoo hauv ntau daim ntawv thov.
Cov tshuaj tua hluav taws uas ua rau kub hnyiab yog cov tshuaj tshwj xeeb uas lawv nthuav dav thaum raug cua sov, tsim ib txheej char uas tiv thaiv cov khoom hauv qab ntawm cov nplaim taws. Hom tshuaj tua hluav taws no feem ntau muaj cov pa roj carbon, cov kua qaub, thiab cov tshuaj ua kom kub hnyiab. Thaum raug cua sov, cov kua qaub ua rau cov pa roj carbon ua rau cov pa roj carbon ua rau cov pa roj char, thaum cov tshuaj ua kom kub hnyiab tsim cov pa roj uas ua rau txheej char nthuav dav. Cov txheej txheem no muab kev tiv thaiv hluav taws zoo heev thiab feem ntau siv rau hauv cov txheej txheej thiab cov yas yooj ywm.
Txawm hais tias cov tshuaj tua hluav taws ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev nyab xeeb hluav taws, lawv siv ua rau muaj kev txhawj xeeb txog ib puag ncig thiab kev noj qab haus huv. Ntau cov tshuaj tua hluav taws halogenated tau txuas nrog cov teebmeem tsis zoo rau kev noj qab haus huv, suav nrog kev cuam tshuam endocrine thiab teeb meem kev loj hlob. Yog li ntawd, cov koom haum tswj hwm tau txwv tsis pub siv lawv ntau ntxiv. Qhov sib txawv, phosphorus thiab inorganic flame retardants feem ntau suav hais tias yog lwm txoj hauv kev nyab xeeb dua, txawm hais tias kev tshawb fawb txuas ntxiv yog qhov tsim nyog los nkag siab tag nrho lawv cov teebmeem mus sij hawm ntev.
Kev xaiv cov tshuaj tua hluav taws hauv cov yas yog cuam tshuam los ntawm ntau yam, suav nrog kev ua haujlwm zoo, kev nyab xeeb, thiab kev cuam tshuam rau ib puag ncig. Thaum cov cai nruj dua thiab kev paub txog cov neeg siv khoom loj hlob, kev lag luam yuav txuas ntxiv hloov mus rau kev xaiv cov tshuaj tua hluav taws uas muaj kev nyab xeeb dua, ruaj khov dua. Kev nkag siab txog ntau hom tshuaj tua hluav taws thiab lawv cov txheej txheem yog qhov tseem ceeb rau cov chaw tsim khoom, cov neeg siv khoom, thiab cov neeg tsim cai lij choj hauv kev nrhiav cov ntaub ntawv muaj kev nyab xeeb dua.
Sichuan Taifeng Tshiab Hluav Taws Kub Retardant Co., Ltdyog ib lub chaw tsim khoom nrog 22 xyoo ntawm kev paub tshwj xeeb hauv kev tsim cov ammonium polyphosphate nplaim taws retardants, peb cov prouducts tau dav xa tawm mus rau txawv teb chaws.
