Thaum nws los txog rau kev tsim hluav taws xob cables, xaiv cov khoom siv rwb thaiv tsev zoo yog qhov tseem ceeb. Cov txheej rwb thaiv tsev tsis tsuas yog tiv thaiv lub cable los ntawm kev puas tsuaj sab nraud tab sis kuj ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm hluav taws xob. Ntawm ntau cov ntaub ntawv muaj, PVC, PE, thiab XLPE yog cov feem ntau siv. Tab sis dab tsi ua rau lawv txawv, thiab koj yuav txiav txim siab li cas qhov twg yog qhov zoo tshaj rau koj cov kev xav tau? Cia peb dhia mus rau hauv cov ntsiab lus hauv ib qho yooj yim, yooj yim to taub.
Txheej txheem cej luam ntawm Txhua Cov Khoom Siv Hluav Taws Xob
PVC (Polyvinyl Chloride)
PVC yog ib hom yas ua los ntawm polymerized vinyl chloride. Nws yog incredibly ntau yam thiab dav siv nyob rau hauv ntau yam industries. Rau cov cables, PVC sawv tawm vim nws ruaj khov, ruaj, thiab tiv taus acids, alkalis, thiab kev laus.
- Soft PVC: Siv tau yooj yim thiab feem ntau siv los ua cov khoom ntim, cov yeeb yaj kiab, thiab cov txheej txheem rwb thaiv tsev hauv cov hluav taws xob qis. Piv txwv suav nrog cov kab hluav taws xob dav dav.
- Rigid PVC: Nyuaj thiab siv los ua cov kav dej thiab cov vaj huam sib luag.
Ib qho ntawm PVC cov yam ntxwv zoo tshaj plaws yog nws cov nplaim taws, uas ua rau nws nrov rau cov hluav taws kub-resistant cables. Txawm li cas los xij, nws muaj qhov tsis zoo: thaum kub hnyiab, nws tso pa tawm cov pa phem thiab corrosive gases.
PE (Polyethylene)
PE yog cov khoom tsis muaj tshuaj lom, lub teeb yuag ua los ntawm polymerizing ethylene. Nws yog nto moo rau nws zoo heev hluav taws xob rwb thaiv tsev zog thiab tsis kam mus tshuaj thiab ya raws. PE yog tshwj xeeb tshaj yog zoo ntawm kev tuav qis kub thiab muaj qhov tsis tshua muaj dielectric tsis tu ncua, uas txo qis zog poob.
Vim tias cov khoom zoo li no, PE feem ntau siv rau insulating high-voltage fais fab cables, cov ntaub ntawv cables, thiab kev sib txuas lus. Nws yog qhov zoo tshaj plaws rau cov ntawv thov uas qhov kev ua tau zoo ntawm hluav taws xob yog qhov tseem ceeb, tab sis nws tsis yog nplaim taws tiv taus li PVC.
XLPE (Cross-linked Polyethylene)
XLPE yog qhov tseem ceeb ntawm kev hloov kho tshiab ntawm PE. Nws yog tsim los ntawm chemically lossis lub cev sib txuas ntawm polyethylene molecules, uas txhim kho nws cov khoom zoo.
Piv nrog rau PE li niaj zaus, XLPE muaj cov cua sov zoo dua, muaj zog dua txhua yam, thiab ua haujlwm zoo dua. Nws kuj tseem tiv taus dej thiab hluav taws xob, ua rau nws zoo tagnrho rau kev thov kev siv xws li underground cables, nuclear fais fab nroj tsuag, thiab marine ib puag ncig.
Qhov txawv ntawm PVC, PE, thiab XLPE
1. Thermal Performance
- PVC: Tsim nyog rau qhov chaw uas muaj qhov kub thiab txias tab sis muaj kev tiv thaiv kub tsawg. Nws tsis yog qhov zoo tagnrho rau cov ntawv thov uas xav tau kev ua haujlwm siab kub.
- PE: Kov kub nruab nrab zoo tab sis pib degrade nyob rau hauv huab cua kub heev.
- XLPE: Excels nyob rau hauv high-kub ib puag ncig. Nws tuaj yeem ua haujlwm tsis tu ncua ntawm 125 ° C thiab tiv taus lub sijhawm luv luv mus txog 250 ° C, ua rau nws zoo meej rau cov ntawv thov kev ntxhov siab.
2. Cov khoom siv hluav taws xob
- PVC: Cov khoom hluav taws xob zoo rau kev siv dav dav.
- PE: Cov rwb thaiv tsev hluav taws xob zoo heev uas tsis muaj hluav taws xob poob, zoo tagnrho rau kev siv hluav taws xob ntau lossis hluav taws xob.
- XLPE: Khaws PE cov khoom hluav taws xob zoo heev thaum muab kev ua haujlwm zoo dua hauv qhov kub thiab txias.
3. Durability thiab kev laus
- PVC: Yooj yim rau kev laus dhau lub sijhawm, tshwj xeeb tshaj yog nyob rau hauv qhov chaw kub kub.
- PE: Zoo dua tiv thaiv kev laus tab sis tseem tsis muaj zog li XLPE.
- XLPE: Kev tiv thaiv zoo rau kev laus, ib puag ncig kev ntxhov siab, thiab kev siv tshuab, ua rau nws xaiv tau ntev.
4. Kev nyab xeeb hluav taws
- PVC: Flame-retardant tab sis tso tawm cov pa luam yeeb thiab cov pa roj thaum hlawv.
- PE: Tsis muaj tshuaj lom tab sis flammable, yog li nws tsis yog qhov kev xaiv zoo tshaj plaws rau thaj chaw hluav taws kub.
- XLPE: Muaj nyob rau hauv cov pa luam yeeb tsawg, tsis muaj halogen variants, ua kom muaj kev nyab xeeb dua thaum muaj hluav taws kub.
5. Tus nqi
- PVC: Qhov kev xaiv pheej yig tshaj plaws, dav siv rau cov khoom siv dav dav.
- PE: Me ntsis kim dua vim nws cov khoom hluav taws xob zoo dua.
- XLPE: Qhov kim tshaj plaws tab sis tsim nyog tus nqi rau kev ua haujlwm siab lossis kev siv tseem ceeb.
