Textile nplaim taws retardancy yog ib qho tseem ceeb ntawm kev ruaj ntseg tshuab tsim los txo cov nplaim taws ntawm cov ntaub, ua kom tsis muaj hluav taws xob thiab hluav taws kub sib kis, yog li txuag lub neej thiab khoom. Kev kho cov nplaim hluav taws xob (FR) ua haujlwm los ntawm ntau yam tshuaj thiab lub cev cov txheej txheem los cuam tshuam lub voj voog hluav taws xob ntawm ntau theem: cua sov, decomposition, ignition, lossis nplaim taws tawm.
Mechanisms tseem ceeb:
1. Txias: Qee qhov FRs nqus cua sov, txo cov ntaub kub hauv qab qhov hluav taws kub.
2. Char Formation: Phosphorus lossis nitrogen-based systems txhawb kev tsim cov txheej txheem tiv thaiv, insulating char txheej es tsis txhob flammable volatiles.
3. Dilution: FRs decompose kom tso cov pa roj uas tsis yog nplaim taws (xws li dej vapor, CO₂, nitrogen), diluting oxygen thiab roj gases ze ntawm cov nplaim taws.
4. Radical Traping: Halogenated tebchaw (txawm hais tias nce ntxiv) tso tawm radicals uas cuam tshuam nrog cov exothermic chain tshua nyob rau hauv cov nplaim taws.
Hom Kev Kho Mob:
Durable: Chemically bonded rau fibers (nrog rau paj rwb, polyester blends), muaj sia nyob ntau yam ntxuav. Piv txwv suav nrog Pyrovatex® rau kev kho cellulose lossis THPC-raws li kev kho mob.
Non-Durable / Semi-Durable: Siv los ntawm cov txheej txheem los yog cov txheej txheem rov qab (feem ntau rau cov khoom siv hluavtaws, cov ntaub pua tsev, cov ntaub pua tsev). Cov no tuaj yeem tawm los yog ploj zuj zus nrog kev ntxuav.
Inherent FR Fibers: Fibers zoo li aramids (Nomex®, Kevlar®), modacrylic, lossis qee yam FR rayons / viscose muaj nplaim taws ua rau lawv cov qauv molecular.
Cov ntawv thov yog qhov tseem ceeb:
Cov khaub ncaws tiv thaiv rau cov neeg tua hluav taws, tub rog, cov neeg ua haujlwm hauv tsev.
Upholstered rooj tog, txaj txaj, thiab ntaub thaiv hauv tsev thiab pej xeem vaj tse.
Kev thauj mus los sab hauv (aircraft, tsheb ciav hlau, tsheb).
Cov ntaub pua plag thiab cov tsev pheeb suab ntaub.
Kev sib tw & kev txiav txim siab:
Sib npaug siab FR kev ua tau zoo nrog kev nplij siab, kav ntev, tus nqi, thiab tshwj xeeb tshaj yog ib puag ncig / kev noj qab haus huv cuam tshuam yog qhov tseem ceeb. Cov kev cai (xws li California TB 117, NFPA 701, EU REACH) tas li hloov zuj zus mus, tsav kev tsim kho tshiab rau kev ruaj khov, tsis muaj tshuaj lom, thiab muaj txiaj ntsig zoo halogen-dawb cov kev daws teeb meem. Kev tshawb fawb tsom mus rau bio-based FRs thiab nanotechnology kom ua tiav cov ntaub ntawv muaj kev nyab xeeb, ua haujlwm siab rau lub neej tom ntej.
