Kev Tswj Hluav Taws: Nkag Siab Txog Kev Tiv Thaiv Hluav Taws Ntawm Cov Ntaub

Kev tiv thaiv hluav taws ntawm cov ntaub yog ib qho thev naus laus zis tseem ceeb rau kev nyab xeeb uas tsim los txo qhov kub hnyiab ntawm cov ntaub, ua rau qeeb qeeb kev hluav taws thiab kev kis hluav taws, yog li ntawd thiaj li cawm tau txoj sia thiab khoom vaj khoom tsev. Kev kho mob tiv thaiv hluav taws (FR) ua haujlwm los ntawm ntau yam tshuaj lom neeg thiab lub cev los cuam tshuam lub voj voog hluav taws ntawm ntau theem: cua sov, lwj, hluav taws, lossis hluav taws nthuav dav.

Cov Txheej Txheem Tseem Ceeb:
1. Kev Txias: Qee cov FRs nqus cua sov, ua rau qhov kub ntawm daim ntaub qis dua qhov kub uas nws hlawv.
2. Kev Tsim Hluav Taws Xob: Cov txheej txheem uas muaj phosphorus lossis nitrogen txhawb nqa kev tsim cov txheej hluav taws xob tiv thaiv, rwb thaiv tsev es tsis txhob siv cov khoom siv hluav taws xob uas yooj yim hlawv.
3. Kev Txo: FRs lwj mus tso tawm cov pa roj uas tsis yooj yim kub hnyiab (xws li cov dej ua pa, CO₂, nitrogen), ua rau cov pa oxygen thiab roj nyob ze ntawm nplaim taws yaj.
4. Kev Ntxeev Radical: Cov tshuaj Halogenated (txawm tias muaj kev txwv ntau zuj zus) tso tawm cov radicals uas cuam tshuam rau cov tshuaj exothermic chain reactions hauv thaj chaw nplaim taws.

Hom Kev Kho Mob:
Siv Tau Ntev: Cov tshuaj sib txuas nrog cov fibers (feem ntau yog paj rwb, polyester sib xyaw), nyob tau ntau zaus ntxuav. Piv txwv li suav nrog Pyrovatex® rau cellulose lossis THPC-based kev kho mob.
Tsis Ruaj Khoov/Ib Nrab Ruaj Khoov: Siv los ntawm kev siv cov txheej txheej lossis cov txheej txheej nraub qaum (feem ntau yog siv rau cov khoom siv hluavtaws, cov rooj zaum, cov ntaub thaiv qhov rais). Cov no yuav tawm los yog txo qis thaum ntxuav.
Cov Fibers FR uas muaj nyob hauv: Cov fibers zoo li aramids (Nomex®, Kevlar®), modacrylic, lossis qee cov FR rayons/viscose muaj cov nplaim taws tsis kam ua rau hauv lawv cov qauv molecular.

Cov kev siv tseem ceeb yog:
Cov khaub ncaws tiv thaiv rau cov neeg tua hluav taws, cov tub rog, cov neeg ua haujlwm hauv kev lag luam.
Cov rooj tog zaum, cov txaj pw, thiab cov ntaub thaiv qhov rais hauv tsev thiab cov tsev pej xeem.
Kev thauj mus los sab hauv (dav hlau, tsheb ciav hlau, tsheb).
Cov ntaub pua plag thiab cov tsev pheeb suab.

Cov Teeb Meem & Kev Xav Txog:
Kev sib npaug ntawm kev ua tau zoo FR siab nrog kev nplij siab, kev ruaj khov, tus nqi, thiab tshwj xeeb tshaj yog kev cuam tshuam rau ib puag ncig / kev noj qab haus huv yog qhov tseem ceeb heev. Cov cai (xws li California TB 117, NFPA 701, EU REACH) hloov pauv tas li, tsav tsheb tsim kho tshiab rau kev ruaj khov dua, tsis muaj tshuaj lom, thiab cov kev daws teeb meem zoo halogen-free. Kev tshawb fawb tsom mus rau bio-based FRs thiab nanotechnology kom ua tiav cov ntaub ntawv muaj kev nyab xeeb dua, ua tau zoo rau yav tom ntej hluav taws-resistant.
