PE (Polyethylene)
Ua ib lub tsho cable, PE muaj kev tiv taus cov dej noo thiab cov tshuaj lom neeg, nrog rau kev ywj pheej zoo. Txawm li cas los xij, raws li tau hais ua ntej, nws qhov kev tiv thaiv hluav taws qis dua me ntsis dua li lwm cov ntaub ntawv.
PVC (Polyvinyl Chloride)
PVC kuj tseem siv ua cov ntaub thaiv cable, muab kev tiv thaiv yooj yim nrog tus nqi qis. Nws cov yam ntxwv zoo ib yam li kev rwb thaiv tsev ua rau nws yog qhov kev xaiv nrov.
4. Lwm Yam Kev Xav Txog Hauv Kev Xaiv Cov Khoom Siv Cable
Ntxiv rau cov xov hlau, cov rwb thaiv tsev, thiab cov tsho, muaj ntau lwm yam uas yuav tsum xav txog thaum xaiv cov ntaub ntawv hluav taws xob cable:
Kub Ua Haujlwm
Nws yog ib qho tseem ceeb kom paub tseeb tias cov khoom siv xaiv tuaj yeem ua haujlwm tau zoo ntawm qhov kub thiab txias uas xav tau. Qhov kub siab dhau heev tuaj yeem ua rau cov khoom puas tsuaj thiab txo qhov ua haujlwm zoo thiab kev nyab xeeb ntawm cov xov hlau.
Ib puag ncig siv
Qhov chaw uas yuav muab cov xov hlau tso rau hauv kuj cuam tshuam rau kev xaiv cov khoom siv. Cov xov hlau uas teeb tsa sab nraum zoov, hauv av, lossis hauv cov chaw ua haujlwm xav tau cov ntaub ntawv uas tuaj yeem tiv taus cov xwm txheej.
Cov Qauv Kev Nyab Xeeb thiab Cov Cai
Nco ntsoov xyuas kom meej tias cov ntaub ntawv xaiv tau ua raws li cov qauv kev nyab xeeb hauv zos thiab thoob ntiaj teb. Qhov no pab xyuas kom meej tias kev nyab xeeb thiab kev nruj raws li cov cai hauv kev teeb tsa hluav taws xob.
Nqi
Tus nqi yog ib qho tseem ceeb uas txiav txim siab hauv ntau qhov projectTxawm hais tias qee cov ntaub ntawv yuav muaj kev ua tau zoo dua, nws yog ib qho tseem ceeb kom sib npaug cov kev cai lij choj nrog cov peev nyiaj muaj.
Xaus
Kev xaiv cov ntaub ntawv rau cov xov hluav taws xob yog ib kauj ruam tseem ceeb thiab yuav tsum tau muaj kev tshuaj xyuas tob tob. Tooj liab thiab txhuas yog cov kev xaiv tseem ceeb rau cov neeg xa hluav taws xob, txhua tus muaj nws tus kheej qhov zoo thiab qhov tsis zoo. Cov ntaub ntawv rwb thaiv tsev xws li PVC, XLPE, thiab PE muaj ntau yam khoom uas tseem ceeb rau kev ua haujlwm zoo thiab kev nyab xeeb ntawm cov xov hluav taws xob. Cov tsho cable muab kev tiv thaiv ntxiv rau cov chaw ib puag ncig thiab cov huab cua. Los ntawm kev xav txog tag nrho cov yam no, cov neeg tsim qauv thiab cov kws ua haujlwm tuaj yeem ua kom ntseeg tau tias cov xov hluav taws xob xaiv yuav ua haujlwm zoo tshaj plaws, kav ntev, thiab muaj kev nyab xeeb rau kev siv.
