Cov xov hluav taws xob sab hauv tsev ua 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 cov xov hluav taws xob sab hauv tsev, tshwj xeeb tshaj yog nyob rau hauv qhov chaw kaw lossis thaj chaw uas muaj cov xov hluav taws xob ntau.
Cov Khoom Siv Uas Tsis Muaj Pa Luam Yeeb Uas Siv Tau Ntau
1. Polyvinyl Chloride (PVC):
PVC yog ib yam khoom siv uas siv dav hauv cov xov hluav taws uas tsis muaj pa taws ntau. Nws muaj cov yam ntxwv zoo heev uas tiv taus hluav taws thiab paub txog nws lub peev xwm tua hluav taws tau. Kev rwb thaiv tsev thiab lub tsho PVC hauv cov xov hluav taws pab tiv thaiv kev kis hluav taws thiab txo cov pa taws thaum lub sijhawm hlawv. Qhov no ua rau PVC yog qhov kev xaiv nrov rau cov xov hluav taws hauv tsev uas kev nyab xeeb hluav taws thiab kev tsim pa taws tsawg yog qhov tseem ceeb.
2. Cov Tshuaj Sib Xyaws Uas Muaj Pa Luam Yeeb Tsawg (LSZH):
Cov tshuaj LSZH, tseem hu ua cov tshuaj tsis muaj halogen, tau siv ntau dua hauv cov xov hlau sab hauv tsev vim lawv cov pa luam yeeb tsawg thiab cov yam ntxwv tsis muaj kuab lom. Cov ntaub ntawv no tau tsim tsis muaj halogens, xws li chlorine lossis bromine, uas paub tias tso tawm cov pa phem thaum hlawv. Cov tshuaj LSZH muab cov nplaim taws zoo heev, tsim pa luam yeeb tsawg, thiab txo cov tshuaj lom, ua rau lawv haum rau cov ntawv thov uas kev nyab xeeb ntawm tib neeg thiab kev txhawj xeeb txog ib puag ncig yog qhov tseem ceeb.

Vim Li Cas Siv Cov Khoom Siv Uas Tsis Muaj Pa Luam Yeeb Hauv Cov Cables Sab Hauv Tsev
1. Kev Nyab Xeeb Hluav Taws:
Qhov laj thawj tseem ceeb rau kev siv cov khoom siv uas tsis muaj pa taws tsawg hauv cov xov hluav taws hauv tsev yog txhawm rau txhim kho kev nyab xeeb ntawm hluav taws. Cov ntaub ntawv no tau tsim tshwj xeeb los txo qhov kev pheej hmoo ntawm kev kis hluav taws thiab txo qhov tso tawm ntawm cov pa phem thiab cov pa luam yeeb ntom ntom thaum muaj hluav taws. Qhov no yog qhov tseem ceeb hauv cov chaw sab hauv tsev uas kev nyab xeeb ntawm cov neeg nyob hauv thiab kev tiv thaiv cov khoom siv muaj nqis yog qhov tseem ceeb.
2. Kev Ua Raws Cai:
Ntau lub teb chaws thiab thaj chaw muaj cov cai thiab cov qauv nruj rau kev nyab xeeb hluav taws thiab pa luam yeeb hauv tsev. Kev siv cov khoom siv uas tsis ua rau muaj pa luam yeeb ntau pab ua kom ua raws li cov cai no. Nws ua rau cov chaw tsim khoom siv hluav taws xob ua tau raws li cov qauv kev nyab xeeb thiab daim ntawv pov thawj uas xav tau, ua rau cov neeg siv khoom thiab cov neeg siv khoom muaj kev thaj yeeb nyab xeeb.
3. Kev Xav Txog Kev Noj Qab Haus Huv Tib Neeg:
Txo qhov kev tso tawm cov pa phem thiab cov pa luam yeeb tuab thaum muaj hluav taws yog qhov tseem ceeb rau kev tiv thaiv tib neeg txoj kev noj qab haus huv. Los ntawm kev siv cov khoom siv uas tsis muaj pa luam yeeb ntau, cov xov hluav taws xob hauv tsev tuaj yeem pab txo qhov kev nqus pa phem, txhim kho kev nyab xeeb thiab kev noj qab haus huv ntawm cov neeg nyob hauv yog tias muaj hluav taws kub.
Kev siv cov khoom siv hluav taws uas tsis muaj pa luam yeeb ntau hauv cov xov hluav taws xob sab hauv tsev yog qhov tseem ceeb rau kev txhim kho kev nyab xeeb hluav taws, txo cov pa luam yeeb, thiab tiv thaiv tib neeg txoj kev noj qab haus huv. Cov ntaub ntawv siv feem ntau xws li PVC, LSZH cov khoom sib xyaw muab cov khoom zoo heev uas tsis muaj hluav taws thiab tsis muaj pa luam yeeb ntau. Los ntawm kev siv cov ntaub ntawv no, cov chaw tsim khoom siv hluav taws xob tuaj yeem ua tau raws li cov cai tswjfwm, xyuas kom muaj kev nyab xeeb ntawm tib neeg, thiab muab cov kev daws teeb meem txhim khu kev qha thiab ib puag ncig rau kev siv hluav taws xob sab hauv tsev.
