Tswj cov cables tau siv dav hauv ntau qhov kev lag luam thiab pej xeem cuam tshuam ncaj qha cuam tshuam rau lub neej pabcuam thiab kev nyab xeeb ntawm cov cable. Xaiv cov ntaub ntawv cua sov-resistant yog qhov tseem ceeb kom ntseeg tau tias qhov kev ua haujlwm ruaj khov ntawm cov cable hauv cov hluav taws xob ib puag ncig. Hauv qab no yog cov lus qhia xaiv cov ntaub ntawv kub-resistant cov ntaub ntawv rau tswj cov cable:
1. Cov khoom siv thiab nws cov cua sov tiv taus
| Khoom Hom|Qhov siab tshaj plaws kub tsis kam (degree)|Nta |
| Polyvinyl chloride (PVC)|70-105|Tus nqi qis, muaj kev hloov tau zoo, tab sis nruab nrab kub tiv taus, tsim nyog rau ib puag ncig ib puag ncig. |
| Hla-Txuas Polyethylene (XLPE)|90-125|Cov cua sov zoo ua kom zoo, muaj zog kho tshuab, haum rau ib puag ncig kub ntau. |
| Fluoroplastic (Flue PTFE)|200-260|Kev kub siab kuj, corrosion kuj, kev kub siab tiv taus, haum rau ib puag ncig. |
| Silicone roj hmab|180-200|Kev hloov tau zoo, muaj siab thiab qis kub tsis kam, haum rau qee zaus uas yuav tsum tau khoov. |
2. Daim ntawv thov cov xwm txheej thiab cov khoom xaiv
- Ib puag ncig kev lag luam: Koj tuaj yeem xaiv PVC lossis XLPE cov ntaub ntawv. Cov khoom siv no muaj tsawg tus nqi thiab tuaj yeem ua kom tau raws li qhov ntsuas kub tsis kam ua feem ntau muaj ib puag ncig.
- Kev kub siab ib puag ncig: hauv kev lag luam xws li metallurgy thiab hluav taws xob, nws tau pom zoo kom xaiv cov khoom lag luam fluoroplastics lossis silicone roj hmab cov ntaub ntawv, uas muaj cov kub silicone, uas muaj cov cua sov li kev kub siab.
- Qhov chaw kub tsawg: hauv qhov chaw txias, cov cheeb tsam txias, thiab koj tuaj yeem tswj cov khoom siv roj hmab tsis tshua muaj zog thiab cov khoom siv tshuab hluav taws xob ntawm cov kub qis.
- Corrosive ib puag ncig: Hauv cov nroj tsuag tshuaj, oSHore platforms, thiab lwm yam. Pom zoo kom xaiv lawv cov tshuaj tsw qab tiv thaiv.
3. Kev txiav txim siab ua tau zoo tshaj plaws
- Cov Khoom Siv Neeg Kho Tshuab: Thaum xaiv cov ntaub ntawv kub-resistant, koj kuj yuav tsum xav txog lawv cov yam ntxwv txhua yam, xws li lub zog ntau tensile thiab coj kev tiv thaiv. Piv txwv li, txawm hais tias fluoroplastics muaj cov cua sov ua kom zoo, lawv lub zog zoo yog qhov qis.
- Hluav Taws Xob Hluav Taws Xob: Cov hluav taws xob hluav taws xob ntawm cov khoom kub-resistant kuj tseem yog ib qho tseem ceeb rau kev xaiv. Piv txwv li, silicone roj hmab muaj cov rwb thaiv tsev zoo thiab haum rau qee lub sijhawm uas xav tau cov khoom siv insulation siab.
- Kev ua haujlwm ib puag ncig: nrog kev txhim kho ntawm ib puag ncig ib puag ncig, kev xaiv ntawm halogen-dawb, cov khoom siv kub tsis tshua muaj cua sov kuj tau txais ntau thiab ntau xim. Piv txwv, cov ntaub ntawv sib xyaw ua cov phom sij thaum hlawv roj thaum hlawv, thaum cov tshuaj fluoroplastics muaj ntau lub zej zog ua phooj ywg.
4. Tus nqi-txiaj ntsig
- Tus nqi pib: Tus nqi ntawm pvc cov ntaub ntawv qis dua, thaum tus nqi ntawm fluoropoplastics thiab silicone cov khoom siv roj hmab ntau dua. Xws li cov peev nyiaj tsawg, PVC lossis XLPE cov ntaub ntawv tuaj yeem xaiv tau.
- Tus nqi ntev: txawm tias thawj tus nqi fluoroplastics thiab silicone cov ntaub ntawv muaj ntau dua, lub sijhawm kub ua haujlwm ntev dua, uas yuav raug nqi ntau dua hauv kev khiav ntev.
Los ntawm cov phau ntawv qhia saum toj no, koj tuaj yeem xaiv cov khoom siv ntsuas kub tshaj plaws cable thiab xav tau kev ua haujlwm tshwj xeeb ntawm cov cable hauv ntau qhov chaw ib puag ncig.
