Cov txheej txheej intumescent yog ib hom khoom siv tiv taus hluav taws uas nthuav dav thaum kub siab los ua ib txheej rwb thaiv tsev. Lawv siv dav hauv kev tiv thaiv hluav taws rau cov tsev, nkoj, thiab cov khoom siv hauv kev lag luam. Cov tshuaj tiv thaiv hluav taws, ua lawv cov khoom xyaw tseem ceeb, tuaj yeem txhim kho cov yam ntxwv tiv taus hluav taws ntawm cov txheej txheej. Thaum muaj kub siab, cov tshuaj tiv thaiv hluav taws tso tawm cov pa roj inert los ntawm kev tshuaj lom neeg, ua rau cov pa oxygen tsis txaus, thiab txhawb kev nthuav dav ntawm cov txheej txheej los ua ib txheej carbonized ntom ntom, zoo cais cov cua sov thiab nplaim taws sib kis.
Cov tshuaj tiv thaiv hluav taws uas siv ntau suav nrog phosphorus, nitrogen, thiab halogen compounds. Cov tshuaj tiv thaiv hluav taws phosphorus ncua kev sib txuas los ntawm kev tsim cov txheej tiv thaiv phosphate; cov tshuaj tiv thaiv hluav taws nitrogen tso tawm nitrogen los ua kom cov pa roj sib txuas tsis sib haum; thiab cov tshuaj tiv thaiv hluav taws halogen cuam tshuam cov txheej txheem sib txuas los ntawm kev ntes cov free radicals. Nyob rau xyoo tas los no, cov tshuaj tiv thaiv hluav taws uas tsis muaj halogen tau maj mam dhau los ua qhov chaw tshawb fawb vim lawv tsis muaj tshuaj lom thiab tsis ua rau ib puag ncig puas tsuaj.
Hauv ntej, kev siv cov tshuaj tua hluav taws hauv cov txheej txheej intumescent tsis yog tsuas yog txhim kho cov khoom tiv taus hluav taws xwb, tab sis kuj muab kev tiv thaiv txhim khu kev qha rau kev nyab xeeb ntawm lub tsev. Yav tom ntej, nrog kev txhim kho ntawm cov kev cai tiv thaiv ib puag ncig, cov tshuaj tua hluav taws zoo thiab ntsuab yuav dhau los ua ib qho kev taw qhia tseem ceeb rau kev txhim kho kev lag luam.
