Daim Ntawv Thov Cov Khoom Siv Cable Uas Tsis Muaj Pa Luam Yeeb Halogen Thiab Cov Khoom Siv Cable Uas Txuas Nrog Polyethylene (XLPE)

Nyob rau xyoo tas los no, qhov kev thov rau cov khoom siv cable uas tsis muaj pa luam yeeb tsawg (LSZH) tau nce siab vim lawv muaj kev nyab xeeb thiab cov txiaj ntsig ib puag ncig. Ib qho ntawm cov ntaub ntawv tseem ceeb siv rau hauv cov cables no yog crosslinked polyethylene (XLPE).

1. Yog dab tsiPolyethylene txuas nrog (XLPE)?

Polyethylene uas txuas nrog, feem ntau hu ua XLPE luv, yog cov khoom siv polyethylene uas tau hloov kho nrog kev ntxiv ntawm tus txuas hla. Cov txheej txheem txuas hla no ua rau cov khoom siv thermal, mechanical thiab chemical zoo dua, ua rau nws zoo tagnrho rau ntau yam kev siv. XLPE siv dav hauv kev tsim kho cov kav dej, cov tshuab cua sov thiab cua txias hydraulic, cov kav dej hauv tsev thiab cov rwb thaiv tsev hluav taws xob siab.

2. Cov txiaj ntsig ntawm XLPE rwb thaiv tsev

XLPE rwb thaiv tsev muaj ntau yam zoo dua li cov ntaub ntawv ib txwm muaj xws li polyvinyl chloride (PVC).
Cov txiaj ntsig no suav nrog:
Thermal stability: XLPE tuaj yeem tiv taus qhov kub siab yam tsis muaj kev hloov pauv thiab yog li ntawd tsim nyog rau cov ntawv thov siab.
Kev tiv thaiv tshuaj lom neeg: Cov qauv sib txuas ua ke muaj kev tiv thaiv tshuaj lom neeg zoo heev, ua kom muaj kev ruaj khov hauv qhov chaw ib puag ncig hnyav.
Lub zog kho tshuab: XLPE muaj cov khoom siv kho tshuab zoo heev, suav nrog kev tiv taus kev hnav thiab kev ntxhov siab tawg.
Yog li ntawd, cov ntaub ntawv cable XLPE feem ntau siv rau hauv kev sib txuas hluav taws xob sab hauv, cov hlau ua los ntawm lub cev muaj zog, cov hlau ua los ntawm lub teeb, cov hlau hluav taws xob siab hauv cov tsheb fais fab tshiab, cov kab tswj teeb liab qis, cov hlau locomotive, cov hlau hauv av, cov hlau tiv thaiv ib puag ncig hauv kev khawb av, cov hlau Marine, cov hlau tso hluav taws xob nuclear, cov hlau TV siab, cov hlau hluav taws xob X-RAY siab thiab cov hlau xa hluav taws xob.
Kev siv tshuab polyethylene crosslinking

Kev sib txuas ntawm polyethylene tuaj yeem ua tiav los ntawm ntau txoj kev, suav nrog kev siv hluav taws xob, peroxide thiab silane crosslinking. Txhua txoj kev muaj nws qhov zoo thiab tuaj yeem xaiv raws li qhov xav tau ntawm daim ntawv thov tshwj xeeb. Qib ntawm kev sib txuas ntawm cov khoom cuam tshuam rau cov khoom ntawm cov khoom. Qhov siab dua qhov ceev ntawm kev sib txuas, qhov zoo dua qhov thermal thiab mechanical zog.

3. Dab tsi yogtsis muaj pa luam yeeb tsawg (LSZH)cov ntaub ntawv?

Cov khoom siv uas tsis muaj pa luam yeeb tsawg (LSZH) yog tsim los kom cov xov hlau uas raug hluav taws tso pa luam yeeb tsawg tshaj plaws thaum hlawv thiab tsis tsim cov pa luam yeeb lom halogen. Qhov no ua rau lawv tsim nyog dua rau kev siv hauv qhov chaw kaw thiab thaj chaw uas muaj cua tsis zoo, xws li qhov av, cov tsheb ciav hlau hauv av thiab cov tsev pej xeem. Cov xov hlau LSZH yog ua los ntawm cov thermoplastic lossis thermoset compounds thiab tsim cov pa luam yeeb thiab cov pa luam yeeb lom tsawg heev, ua kom pom kev zoo dua thiab txo cov kev pheej hmoo kev noj qab haus huv thaum muaj hluav taws.

4. Daim ntawv thov khoom siv cable LSZH

Cov ntaub ntawv cable LSZH siv rau ntau yam kev siv uas kev nyab xeeb thiab kev txhawj xeeb txog ib puag ncig yog qhov tseem ceeb.
Qee cov ntawv thov tseem ceeb suav nrog:
Cov ntaub ntawv cable rau cov tsev pej xeem: LSZH cables feem ntau siv rau hauv cov tsev pej xeem xws li tshav dav hlau, chaw nres tsheb ciav hlau thiab tsev kho mob kom ntseeg tau tias muaj kev nyab xeeb thaum muaj hluav taws.
Cov cables rau kev thauj mus los: Cov cables no yog siv rau hauv tsheb, dav hlau, tsheb ciav hlau thiab nkoj kom txo qhov kev pheej hmoo ntawm cov pa lom thaum muaj hluav taws.
Cov xov hlau hauv av thiab hauv av: Cov xov hlau LSZH muaj cov yam ntxwv tsis muaj pa luam yeeb thiab halogen, ua rau lawv zoo tagnrho rau kev siv hauv cov xov hlau hauv av thiab hauv av.
Cov cables Class B1: Cov ntaub ntawv LSZH yog siv rau hauv cov cables Class B1, uas tau tsim los ua kom tau raws li cov qauv kev nyab xeeb hluav taws thiab siv rau hauv cov tsev siab thiab lwm yam khoom siv tseem ceeb.

Cov kev nce qib tsis ntev los no hauv XLPE thiab LSZH thev naus laus zis tsom mus rau kev txhim kho cov khoom siv ua haujlwm thiab nthuav nws cov ntawv thov. Cov kev tsim kho tshiab suav nrog kev tsim cov polyethylene sib txuas ua ke (XLHDPE), uas tau txhim kho kev tiv taus cua sov thiab kev ruaj khov.

Cov khoom siv polyethylene (XLPE) uas siv tau ntau yam thiab ruaj khov thiab cov khoom siv cable uas tsis muaj pa luam yeeb tsawg (LSZH) yog siv dav hauv ntau yam lag luam vim lawv cov khoom siv thermal, chemical thiab mechanical zoo heev. Lawv cov ntawv thov txuas ntxiv mus loj hlob nrog kev nce qib ntawm thev naus laus zis thiab qhov kev thov nce ntxiv rau cov khoom siv muaj kev nyab xeeb dua thiab zoo rau ib puag ncig.

Raws li qhov kev thov rau cov ntaub ntawv cable txhim khu kev qha thiab muaj kev nyab xeeb txuas ntxiv nce ntxiv, XLPE thiab LSZH yuav tsum ua lub luag haujlwm tseem ceeb hauv kev ua kom tau raws li cov kev cai no.
