Nyob rau hauv xyoo tas los no, qhov kev thov rau cov khoom siv hluav taws xob tsis muaj pa halogen-free (LSZH) tau nce siab vim lawv cov txiaj ntsig kev nyab xeeb thiab ib puag ncig. Ib qho ntawm cov ntaub ntawv tseem ceeb siv hauv cov cables no yog crosslinked polyethylene (XLPE).
1. Dab tsi yogHla-txuas Polyethylene (XLPE)?
Hla-txuas polyethylene, feem ntau luv luv XLPE, yog cov khoom siv polyethylene uas tau hloov kho nrog qhov sib ntxiv ntawm tus crosslinker. Qhov kev sib txuas ntawm kev sib txuas no txhim kho cov thermal, mechanical thiab chemical zog ntawm cov khoom, ua rau nws zoo tagnrho rau ntau yam kev siv. XLPE tau siv dav hauv kev tsim cov kav dej hauv tsev, hydraulic radiant cua sov thiab cua txias tshuab, kav dej hauv tsev thiab hluav taws xob hluav taws xob hluav taws xob.
2. Qhov zoo ntawm XLPE rwb thaiv tsev
XLPE rwb thaiv tsev muaj ntau qhov zoo dua li cov khoom siv xws li polyvinyl chloride (PVC).
Cov txiaj ntsig no suav nrog:
Thermal stability: XLPE tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj deformation thiab yog li tsim nyog rau kev siv siab.
Chemical resistance: Cov qauv crosslinked muaj cov tshuaj tiv thaiv zoo heev, ua kom ruaj khov nyob rau hauv ib puag ncig hnyav.
Mechanical zog: XLPE muaj cov cuab yeej zoo heev, nrog rau kev hnav thiab kev ntxhov siab tawg.
Yog li ntawd, XLPE cable cov ntaub ntawv feem ntau siv rau hauv kev sib txuas hauv hluav taws xob, lub cev muaj zog, cov teeb pom kev zoo, cov xaim hluav taws xob hauv cov tsheb tshiab, cov kab hluav taws xob tsis tshua muaj hluav taws xob, cov kab hluav taws xob, cov kab hluav taws xob, subway cables, mining environmental protection cables, Marine cables, nuclear. fais fab tso cables, TV high-voltage cables, X-RAY high-voltage cables thiab fais fab kis cables.
Polyethylene crosslinking technology
Crosslinking ntawm polyethylene tuaj yeem ua tiav los ntawm ntau txoj hauv kev, suav nrog hluav taws xob, peroxide thiab silane crosslinking. Txhua txoj kev muaj nws qhov zoo thiab tuaj yeem xaiv tau raws li cov ntawv thov tshwj xeeb. Qhov degree ntawm crosslinking ho cuam tshuam rau cov khoom ntawm cov khoom. Qhov siab dua qhov crosslinking ceev, qhov zoo dua thermal thiab mechanical zog.
3. Dab tsi yogTsis tshua muaj pa halogen dawb (LSZH)cov ntaub ntawv?
Cov khoom siv hluav taws xob tsis muaj pa halogen tsawg (LSZH) yog tsim los kom cov cables raug hluav taws tso tawm tsawg kawg ntawm cov pa luam yeeb thaum hlawv thiab tsis tsim cov pa luam yeeb halogen. Qhov no ua rau lawv tsim nyog siv rau hauv qhov chaw kaw thiab thaj chaw uas muaj cua tsis zoo, xws li tunnels, underground railway networks thiab pej xeem vaj tse. LSZH cables yog tsim los ntawm cov khoom siv thermoplastic lossis cov khoom siv thermoset thiab tsim cov pa taws tsawg heev thiab cov pa phem, ua kom pom kev zoo dua thiab txo kev pheej hmoo ntawm kev noj qab haus huv thaum hluav taws kub.
4. LSZH cable cov ntaub ntawv thov
LSZH cable cov ntaub ntawv yog siv nyob rau hauv ntau yam kev siv uas muaj kev nyab xeeb thiab ib puag ncig kev txhawj xeeb tseem ceeb heev.
Qee cov ntawv thov tseem ceeb suav nrog:
Cov ntaub ntawv cable rau pej xeem cov tsev: LSZH cables feem ntau yog siv rau hauv cov tsev pej xeem xws li tshav dav hlau, chaw nres tsheb ciav hlau thiab tsev kho mob kom muaj kev nyab xeeb thaum muaj hluav taws kub.
Cables rau kev thauj mus los: Cov cables no yog siv rau hauv tsheb, dav hlau, tsheb ciav hlau thiab nkoj kom txo qis kev pheej hmoo ntawm cov pa phem thaum muaj hluav taws kub.
Qhov thiab underground railway network cables: LSZH cables muaj cov pa luam yeeb tsawg thiab halogen-dawb yam ntxwv, ua rau lawv zoo tagnrho rau siv nyob rau hauv qhov thiab underground railway networks.
Class B1 cables: LSZH cov ntaub ntawv yog siv nyob rau hauv Class B1 cables, uas yog tsim los kom ua tau raws li cov qauv kev ruaj ntseg hluav taws thiab siv nyob rau hauv cov tsev siab thiab lwm yam tseem ceeb infrastructure.
Kev nce qib tsis ntev los no hauv XLPE thiab LSZH thev naus laus zis tsom rau kev txhim kho cov khoom siv kev ua tau zoo thiab nthuav dav nws cov ntawv thov. Kev tsim kho tshiab suav nrog kev txhim kho ntawm high-density cross-linked polyethylene (XLHDPE), uas tau txhim kho cov cua sov thiab ua haujlwm ntev.
Ntau yam thiab ruaj khov, cov ntaub ntawv sib txuas ntawm polyethylene (XLPE) thiab cov khoom siv hluav taws xob tsis tshua muaj hluav taws xob xoom-halogen (LSZH) tau siv dav hauv ntau qhov kev lag luam vim lawv cov thermal, tshuaj lom neeg thiab cov khoom siv zoo heev. Lawv cov ntawv thov txuas ntxiv mus ntxiv nrog kev nce qib ntawm kev siv thev naus laus zis thiab kev xav tau ntau ntxiv rau cov ntaub ntawv muaj kev nyab xeeb thiab zoo ib puag ncig.
Raws li qhov kev thov rau cov khoom siv txuas ntxiv txhim khu kev qha thiab kev nyab xeeb txuas ntxiv, XLPE thiab LSZH yuav tsum tau ua lub luag haujlwm tseem ceeb hauv kev ua kom tau raws li cov cai no.
