Daim ntawv thov thiab qhov tseem ceeb ntawm nplaim hluav taws kub nyhiab hauv Intumescent txheej

Intumescent coatings yog ib yam khoom siv hluav taws kub uas nthuav dav ntawm qhov kub thiab txias los tsim ib txheej insulating. Lawv tau siv dav hauv kev tiv thaiv hluav taws rau cov tsev, nkoj, thiab cov khoom siv hauv tsev. Cov nplaim hluav taws kub hnyiab, raws li lawv cov khoom xyaw tseem ceeb, tuaj yeem txhim kho cov hluav taws kub tsis zoo ntawm cov txheej txheem. Nyob rau hauv qhov kub thiab txias, nplaim retardants tso tawm inert gases los ntawm cov tshuaj tiv thaiv, dilute lub oxygen concentration, thiab txhawb lub expansion ntawm lub txheej los ua ib tug tuab carbonized txheej, zoo cais tawm ntawm tshav kub thiab nplaim taws.

Feem ntau siv cov nplaim hluav taws xob muaj xws li phosphorus, nitrogen, thiab halogen compounds. Phosphorus nplaim retardants ncua combustion los ntawm tsim ib tug phosphate tiv thaiv txheej; nitrogen nplaim retardants tso nitrogen rau dilute combustible gases; thiab halogen nplaim retardants cuam tshuam cov combustion saw cov tshuaj tiv thaiv los ntawm kev ntes cov dawb radicals. Nyob rau hauv xyoo tas los no, ib puag ncig tus phooj ywg nplaim taws retardants (xws li halogen-dawb nplaim retardants) tau maj mam dhau los ua kev tshawb fawb hotspot vim lawv cov toxicity tsawg thiab ib puag ncig tus phooj ywg.

Nyob rau hauv luv luv, daim ntawv thov ntawm nplaim retardants nyob rau hauv intumescent txheej tsis tsuas yog txhim kho fireproof zog, tab sis kuj muab kev ruaj ntseg kev tiv thaiv rau lub tsev. Nyob rau hauv lub neej yav tom ntej, nrog rau kev txhim kho ntawm kev tiv thaiv ib puag ncig, kev ua haujlwm zoo thiab cov nplaim taws ntsuab yuav dhau los ua ib qho tseem ceeb rau kev txhim kho kev lag luam.
