Flame retardant (FR) khaub ncaws yog kab kawg ntawm kev tiv thaiv rau cov neeg ua haujlwm nyob rau hauv siab - kev lag luam muaj kev pheej hmoo xws li petrochemicals, fais fab, thiab vuam. Nws qhov kev tiv thaiv kev ua tau zoo nyob ntawm qhov zoo ntawm FR fabrics thiab ua raws li cov qauv ntsuas thoob ntiaj teb. Kab lus no qhia txog cov ntsiab lus ntawm FR cov ntaub, lawv cov yam ntxwv, thiab cov qauv kev sim thoob ntiaj teb, pab pawg neeg yuav khoom thiab cov thawj coj saib xyuas kev nyab xeeb xaiv cov khaub ncaws tiv thaiv tsim nyog.
1. Core Flame Retardant Fabric Hom
FR fabrics tau muab faib ua ob pawg raws li lawv cov nplaim hluav taws xob, nrog qhov sib txawv tseem ceeb hauv kev ua haujlwm thiab kev pabcuam lub neej:
Inherently Flame-Resistant (IFR) Fabrics: Nplaim retardancy yog tsim rau hauv cov qauv fiber ntau molecular, tsis nyob ntawm cov tshuaj coatings. Cov ntaub ntawv tseem ceeb muaj xws li:
Aramid (Nomex®/Kevlar®): Cov khoom siv FR siv dav tshaj plaws, nrog rau kev txwv oxygen index (LOI) Ntau dua lossis sib npaug li 28%, tus kheej - tua tsis pub dhau 2 vib nas this tom qab tawm hauv nplaim taws, tsis muaj dej ntws, thiab khaws cov kev ua tau zoo tom qab 100+ ntxuav. Haum rau ntev - siv nyob rau hauv petrochemical thiab fais fab kev lag luam.
PBI: Qhov siab tshaj plaws -kev ua tau zoo FR fiber ntau, tiv taus kub txog 560 degree, zoo tagnrho rau cov lus teb thaum muaj xwm txheej ceev thiab siab - kub smelting.
Modacrylic blends: Sib npaug nplaim taws tiv thaiv thiab kev nplij siab, tus nqi- zoo rau kev siv txhua hnub hauv cov xwm txheej kev lag luam.
Tshuaj kho mob FR Fabrics: Ordinary fabrics (paj rwb, polyester) yog kho nrog FR chemicals. Lawv muaj tus nqi pib qis tab sis poob nplaim taws tom qab 10-25 ntxuav, ua rau tawv tawv thiab khaus tawv nqaij. Tsuas yog siv rau lub sijhawm luv luv lossis siv pov tseg.
2. Ntiaj teb no yuav tsum xeem cov qauv
Cov khaub ncaws FR tsim nyog yuav tsum xeem dhau - tog thib peb thiab ua tau raws li cov qauv kev lag luam hauv cheeb tsam:
North America: NFPA 2112 & ASTM F1506NFPA 2112 yog tus qauv tseem ceeb rau kev lag luam FR khaub ncaws, xav tau: 12-thib ob qhov kev sim nplaim taws, lub sijhawm tom qab lub nplaim taws tsawg dua lossis sib npaug li 2 vib nas this, tsis muaj dej ntws; thermal tiv thaiv kev ua tau zoo (TPP) Ntau dua lossis sib npaug li 6 cal / cm². ASTM F1506 ntxiv arc flash tiv thaiv cov cai rau kev lag luam fais fab.
Cov European Union: EN ISO 11612Qhia txog qib kev ua tau zoo rau cov khaub ncaws tiv thaiv tshav kub thiab nplaim taws, muab faib ua A1-A4 (nplaim hluav taws xob) thiab BF (heat resistance) qib. Nws kuj suav nrog cov kev ntsuam xyuas rau molten hlau txaws tsis kam, yuav tsum tau siv rau vuam thiab metallurgy kev lag luam.
Tuam Tshoj: GB 8965.1-2020Lub teb chaws tus qauv rau FR tiv thaiv khaub ncaws, ua raws li cov ntsuas thoob ntiaj teb, xav tau LOI Ntau dua lossis sib npaug li 28%, rhuav lub zog Ntau dua lossis sib npaug rau 100N, thiab 50 ntxuav yam tsis muaj kev ua haujlwm tsis zoo rau IFR fabrics.
3. Cov lus qhia yuam kev & cov lus qhia xaiv
Kev ntseeg yuam kev 1: Tag nrho cov ntaub FR muaj cov nplaim taws mus tas li. Tsuas yog IFR fabrics khaws kev ua tau zoo rau lawv lub neej kev pabcuam tag nrho.
Kev tsis ntseeg 2: Tus nqi TPP siab dua yog ib txwm zoo dua. Cov ntaub tuab tuab heev txo qis kev txav mus los thiab ua rau muaj kev ntxhov siab kub.
Lub hauv paus ntsiab lus ntawm kev xaiv: Sib phim hom ntaub thiab qib tus qauv rau qhov kev pheej hmoo ntawm chaw ua haujlwm, thiab xav kom cov neeg muag khoom muab cov ntaub ntawv pov thawj thib peb uas siv tau - tog neeg.
Xaus
Xaiv cov ntaub FR zoo thiab ua kom ntseeg tau tias ua raws li cov qauv kev sim yog qhov tseem ceeb rau kev tiv thaiv cov neeg ua haujlwm kev nyab xeeb thiab tsis txhob raug nplua. Inherently nplaim taws-cov ntaub uas tiv taus yog qhov kev xaiv zoo tshaj plaws rau kev siv sijhawm ntev- siv, thaum cov ntaub kho mob tsuas yog tsim rau cov xwm txheej ib ntus xwb.
