Kev tshawb pom tshiab hauv kev siv cov tshuaj phosphorus-nitrogen flame retardants hauv cov txheej txheem intumescent

Tsis ntev los no, ib pab pawg tshawb fawb txog cov khoom siv hauv tsev uas paub zoo tau tshaj tawm tias nws tau tsim cov tshuaj tua hluav taws phosphorus-nitrogen uas ua haujlwm tau zoo thiab zoo rau ib puag ncig hauv kev lag luam ntawm cov txheej txheej intumescent, uas ua rau cov txheej txheej tiv thaiv hluav taws thiab kev phooj ywg ib puag ncig zoo dua qub. Los ntawm kev sib koom ua ke ntawm cov phosphorus thiab nitrogen, cov tshuaj tua hluav taws sai sai tsim cov txheej carbonized ntom ntom ntawm qhov kub siab, ua kom sov thiab nplaim taws zoo, thaum tso cov pa roj inert los tiv thaiv kev sib xyaw ua ke.

Piv nrog rau cov tshuaj halogen nplaim taws ib txwm muaj, cov tshuaj phosphorus-nitrogen nplaim taws tsis yog tsuas yog tsis muaj tshuaj lom thiab tsis muaj kuab paug xwb, tab sis kuj muaj kev ruaj khov thermal thiab kev ua haujlwm nplaim taws zoo dua. Cov ntaub ntawv sim qhia tau tias qhov piv ntawm kev nthuav dav ntawm cov txheej txheem intumescent nrog kev ntxiv cov tshuaj nplaim taws no ntawm qhov kub siab tau nce 30%, thiab lub sijhawm tiv thaiv hluav taws tau ntev dua 40%.

Qhov kev tshawb pom tshiab no muab kev daws teeb meem zoo dua rau kev nyab xeeb hluav taws hauv kev tsim kho, nkoj, thiab lwm yam, thiab tseem txhawb kev lag luam txheej intumescent kom txav mus rau kev tiv thaiv ntsuab thiab ib puag ncig. Yav tom ntej, pab neeg npaj yuav ua kom zoo dua cov mis thiab txhawb kev siv cov tshuaj phosphorus-nitrogen flame retardants loj.
