Kev nce qib tshiab hauv cov tshuaj phosphorus-nitrogen flame retardants

Muaj kev nce qib tshiab hauv kev tshawb fawb thiab kev txhim kho cov tshuaj tua hluav taws phosphorus-nitrogen, pab txhim kho cov ntaub ntawv tiv thaiv hluav taws ntsuab.

Tsis ntev los no, ib pab pawg tshawb fawb hauv tsev tau ua tiav qhov kev tshawb fawb loj hauv kev siv cov tshuaj tua hluav taws phosphorus-nitrogen thiab ua tiav kev tsim cov tshuaj tua hluav taws tshiab uas ua haujlwm tau zoo thiab zoo rau ib puag ncig. Los ntawm kev sib koom ua ke ntawm cov phosphorus thiab nitrogen, cov tshuaj tua hluav taws tsim cov txheej carbonization ruaj khov ntawm qhov kub siab thiab tso tawm cov pa roj inert, tiv thaiv kev sib xyaw ua ke, thiab muaj cov yam ntxwv tiv thaiv ib puag ncig uas tsis muaj pa luam yeeb thiab tsis muaj tshuaj lom.

Piv nrog rau cov tshuaj tua hluav taws halogen ib txwm muaj, cov tshuaj tua hluav taws phosphorus-nitrogen tsis yog tsuas yog tiv thaiv kev tso tawm cov tshuaj lom neeg xwb, tab sis kuj qhia tau tias muaj kev ruaj khov thermal thiab kev ua haujlwm zoo dua ntawm cov tshuaj tua hluav taws. Cov kev sim qhia tau tias kev siv cov tshuaj tua hluav taws no hauv cov ntaub ntawv polymer tuaj yeem txhim kho cov khoom tua hluav taws ntau dua 40% thiab txo cov pa luam yeeb ntau dua 50%.

Qhov kev ua tiav no muab ib txoj kev taw qhia tshiab rau kev txhim kho cov ntaub ntawv tiv taus hluav taws hauv kev tsim kho, khoom siv hluav taws xob, kev thauj mus los, thiab lwm yam, thiab txhawb kev txhim kho ntawm kev lag luam tiv thaiv hluav taws kom ntsuab thiab ua haujlwm tau zoo. Yav tom ntej, pab neeg yuav ua kom zoo dua cov txheej txheem tsim khoom, txhawb kev siv cov tshuaj phosphorus-nitrogen tiv thaiv hluav taws ntau, thiab pab ua tiav lub hom phiaj "ob chav carbon".
