Nyob sab hauv tsev cable ua si lub luag haujlwm tseem ceeb hauv kev muab kev sib txuas rau ntau yam kev siv. Kev Nyab Xeeb yog qhov tseem ceeb tshaj plaws thaum nws los txog rau sab hauv tsev, tshwj xeeb hauv cov chaw kaw lossis thaj chaw uas muaj lub zog siab ntawm cov cable.
Feem ntau yog siv cov pa hluav taws uas tsis tshua muaj pa hluav taws-retardant
1. Polyvinyl chloride (PVC):
PVC yog dav siv cov pa hluav taws me me-retardant hauv cov ntaub ntawv sab hauv tsev. Nws muaj cov nplaim hluavtaws zoo-retardant thiab yog paub rau nws tus kheej-extinguishing muaj peev xwm. PVC rwb thaiv tsev thiab Jua jacking nyob rau hauv cables pab tiv thaiv kev kis hluav taws thiab txo cov pa tawm haus luam yeeb thaum lub sijhawm pa taws. Qhov no ua rau PVC ib qho kev xaiv nrov rau sab hauv tsev hluav taws kub uas muaj kev nyab xeeb hluav taws thiab tsis muaj pa luam yeeb tsawg.
2. Tsawg pa taws cov pa xo Halogen (LSZH) cov lus teb:
LSZH tebchaw, tseem hu ua halogen-dawb tebchaw, muaj nce nyob rau hauv sab hauv tsev cable vim lawv cov pa luam yeeb tsawg thiab tsawg tus yam ntxwv tsis tshua muaj tshuaj lom. Cov ntaub ntawv no tau tsim cov qauv halogens, xws li chlorine lossis bromine, uas tau paub txog emit lom gases thaum hlawv. LSZH cov ntsiab lus muab cov nplaim ntsuab zoo, thiab txo cov pa hluav taws tsis zoo, ua rau lawv muaj kev nyab xeeb rau tib neeg thiab ib puag ncig muaj feem ntau.

Cov laj thawj uas siv cov nplaim hluav taws xob tsawg-retardant hauv sab hauv tsev cable
1. Hluav Taws Kub Kev Nyab Xeeb:
Qhov laj thawj tseem ceeb rau kev siv cov nplaim hluav taws xob tsawg-retardant cov ntaub ntawv nyob rau sab hauv tsev cables yog los txhim kho hluav taws kev nyab xeeb. Cov ntaub ntawv no tau tsim tshwj xeeb los txo qis kev pheej hmoo ntawm kev tawm hluav taws thiab txo qis kev tso pa tawm ntawm cov roj toxic thiab tuab cov pa taws thaum muaj hluav taws. Qhov no yog qhov tseem ceeb nyob rau hauv ib puag ncig sab hauv tsev uas cov neeg nyob hauv kev nyab xeeb thiab kev tiv thaiv ntawm cov khoom muaj txiaj ntsig zoo.
2. Kev tswj hwm ua raws li:
Ntau lub teb chaws thiab cov cheeb tsam muaj cov kev cai tswj thiab cov qauv nyob rau hauv kev nyab xeeb hluav taws thiab pa roj carrission hauv chaw nyob sab hauv tsev. Siv cov nplaim hluav taws xob tsawg-retardant cov khoom siv pab kom ua raws li cov cai no. Nws pab tau cable tuam txhab kom tau raws li cov qauv kev nyab xeeb thiab ntawv pov thawj, muab kev thaj yeeb nyab xeeb rau cov neeg siv khoom thiab cov neeg siv khoom xaus.
3. Tib neeg cov kev txiav txim siab txog kev noj qab haus huv:
Txo qhov tso tawm cov roj lom thiab cov pa luam yeeb ntom nti thaum hluav taws yog qhov tseem ceeb rau kev tiv thaiv tib neeg kev noj qab haus huv. Los ntawm kev siv cov pa hluav taws me-retardant, cov ntaub pua chaw nyob sab hauv tuaj yeem pab txo cov pa roj teeb uas muaj kev phom sij, txhim kho kev nqus tau kom muaj kev phom sij thiab muaj hluav taws kub.
Daim ntawv thov ntawm cov pa luam yeeb tsawg-retardant hauv sab hauv tsev hluav taws xob yog qhov tseem ceeb rau kev txhim kho hluav taws, txo cov pa hluav taws xob, thiab tiv thaiv cov neeg noj qab haus huv. Cov ntaub ntawv uas nquag siv xws li PVC, LSZH cov ntsiab lus muab cov nplaim taws zoo heev-retardant thiab ntau cov pa luam yeeb. Los ntawm kev siv cov ntaub ntawv no, cable cov tuam ntxhab tuaj yeem tuaj yeem tuaj yeem ua kom tau cov kev cai tswj hwm, thiab cov kev txhim khu kev txhim khu thiab cov ntsiab lus txhawb nqa rau sab hauv qab daim ntawv thov.
