Kev tiv thaiv ib puag ncig yog qhov tseem ceeb heev rau kev siv cable kom ntseeg tau tias muaj kev ua haujlwm ntev, kev nyab xeeb, thiab kev ntseeg siab. Cov cables feem ntau raug rau cov xwm txheej hnyav xws li dej / noo noo, tshuaj lom neeg, UV hluav taws xob, kub heev, thiab kev ntxhov siab ntawm lub tshuab. Kev xaiv cov khoom siv zoo nrog kev tiv thaiv ib puag ncig tsim nyog yog qhov tseem ceeb rau kev tswj hwm kev ua haujlwm thiab txuas ntxiv lub neej kev pabcuam ntawm cable.
Tshooj no tshawb nrhiav ntau hom kev tiv thaiv ib puag ncig uas xav tau hauv ntau daim ntawv thov cable.
Lub tsho sab nraud lossis lub hnab ua haujlwm ua thawj kab tiv thaiv tiv thaiv cov yam ntxwv ib puag ncig. Nws feem ntau raug rau cov tshuaj lom neeg, dej, qhov kub thiab txias hloov pauv, thiab hluav taws xob UV. Cov ntaub ntawv tseem ceeb siv rau lub tsho sab nraud yogPVC (Polyvinyl Chloride), PE (Polyethylene), thiabLSZH (Tsis Muaj Pa Luam Yeeb Tsawg Halogen), txhua tus muab ntau qib kev tiv taus nyob ntawm seb daim ntawv thov xav tau dab tsi.
1. Kev Tiv Thaiv Tshuaj, Roj, thiab Hydrocarbon
Thaum lub sijhawm teeb tsa thiab lub neej ua haujlwm ntawm cov xov hlau, kev raug tshuaj lom neeg, roj, lossis hydrocarbons tuaj yeem tshwm sim, los ntawm kev nchuav tsis raug lossis kev sib cuag tas li hauv cov chaw ua haujlwm. Kev raug mob no tuaj yeem ua rau lub plhaub sab nraud puas tsuaj, ua rau tawg, o, lossis poob ntawm cov khoom siv kho tshuab.
Kev xaiv cov ntaub ntawv uas muaj zog tiv taus tshuaj lom neeg yog qhov tseem ceeb kom ntseeg tau tias cov xov hlau tswj tau nws qhov kev ncaj ncees, kev ua tau zoo, thiab kev ntseeg tau thoob plaws nws lub neej.
Hom Kev Raug Tshuaj Lom:
Cov Tshuaj Uas Muaj Pa: Cov tshuaj uas muaj pa feem ntau muaj kev cuam tshuam tsawg dua nrog cov polymers vim lawv tsis nkag mus tob rau hauv cov khoom. Txawm li cas los xij, cov pa uas muaj kev cuam tshuam xws li chlorine lossis ozone tuaj yeem ua rau qhov chaw puas tsuaj thiab cuam tshuam rau cov khoom ntawm cov polymer.
Cov Tshuaj Ua Kua: Cov tshuaj ua kua feem ntau muaj kev pheej hmoo siab dua vim lawv lub peev xwm kis mus rau hauv cov khoom. Qhov no tuaj yeem ua rau o, ua kom yas, lossis cov tshuaj lom neeg sab hauv hauv cov polymer matrix, ua rau cov khoom siv kho tshuab thiab hluav taws xob puas tsuaj.
Kev Ua Haujlwm ntawm Cov Khoom Siv:
PE (Polyethylene): Muaj kev tiv taus zoo rau ntau yam tshuaj lom neeg thiab hydrocarbons. Nws ua tau zoo hauv cov chaw ib puag ncig tshuaj lom neeg tab sis tuaj yeem rhiab heev rau cov neeg sawv cev oxidizing muaj zog.
PVC (Polyvinyl Chloride): Ua kom pom tseeb tias nws tiv taus roj, tshuaj lom neeg, thiab hydrocarbons zoo heev, tshwj xeeb tshaj yog thaum tsim cov tshuaj ntxiv uas tiv taus roj.
LSZH (Low Smoke Zero Halogen): Muaj kev tiv taus cov tshuaj lom neeg thiab roj me ntsis. Cov tshuaj LSZH feem ntau yog tsim los rau kev nyab xeeb hluav taws (tsim cov pa luam yeeb tsawg thiab tsis muaj tshuaj lom thaum lub sijhawm hlawv). Txawm li cas los xij, cov tshuaj LSZH tshwj xeeb tuaj yeem ua tiav kev tiv taus roj thiab tshuaj lom neeg zoo dua thaum xav tau.
2. Dej thiab noo noo tsis kam
Cov xov hlau feem ntau raug dej los yog cov dej noo ntau thaum lub sijhawm teeb tsa thiab thoob plaws lawv lub neej ua haujlwm. Kev raug dej noo ntev ntev tuaj yeem ua rau kev puas tsuaj ntawm cov khoom rwb thaiv tsev, xeb ntawm cov khoom hlau, thiab txo qis kev ua haujlwm ntawm cov xov hlau.
Yog li ntawd, kev tiv thaiv dej yog qhov tseem ceeb rau ntau daim ntawv thov cable, tshwj xeeb tshaj yog nyob rau sab nraum zoov, hauv av, lossis chaw nyob hauv hiav txwv.
Ntawm cov ntaub ntawv siv rau hauv lub tsho, PE (Polyethylene) muaj kev tiv thaiv dej zoo heev, ua rau nws yog qhov kev xaiv zoo rau cov ntawv thov uas xav tau kev tiv thaiv mus sij hawm ntev tiv thaiv cov dej noo nkag.
Cov xov hluav taws xob tsawg thiab nruab nrab uas muaj LSZH lossis PVC feem ntau tsis pom zoo kom teeb tsa rau hauv qhov chaw uas muaj dej ntws tas mus li, xws li cov av nplaum lossis thaj chaw hauv qab dej. Qhov sib txawv, PE sheaths tiv taus dej ntau dua los ntawm kev rwb thaiv tsev ntawm cov xov hluav taws xob. Yog li ntawd, PE-sheathed cables zoo dua rau cov xwm txheej ntub thiab yuav ua tiav lawv lub neej tsim qauv tag nrho.
Tsim Cov Cable Uas Tsis Muaj Dej:
Yuav kom ua tiav qhov kev tiv thaiv dej tiag tiag hauv cov cables, ob qho kev tiv thaiv tseem ceeb tau txiav txim siab:
Kev Tiv Thaiv Dej Radial:
Ua tiav los ntawm kev siv cov ntaub ntawv xws li cov hlau txhuas lossis cov hlau/hlau laminated tapes ua ke nrog cov polymers tshwj xeeb.
Kev Tiv Thaiv Dej Ntev:
Ua tiav los ntawm kev siv cov ntaub nplaum thaiv dej lossis cov hmoov uas tiv thaiv kev txav mus los ntawm dej raws qhov ntev ntawm lub cable.
Kev Tiv Thaiv Kev Nkag (IP) Qib thiab AD7/AD8 Chav Kawm:
Cov ntaub ntawv qhia txog cov chav kawm tiv thaiv IP thiab kev ntsuas (xws li AD7 lossis AD8) yuav raug qhia rau hauv ib tsab xov xwm sib cais.
3. Kev Tiv Thaiv UV
Kev nkag siab thiab xaiv qhov kev tiv thaiv ib puag ncig uas tsim nyog rau kev siv cable yog qhov tseem ceeb rau kev ua haujlwm ntev, kev nyab xeeb, thiab kev ntseeg siab. Cov yam xws li kev raug tshuaj lom neeg, dej nkag, hluav taws xob UV, thiab kev hloov pauv kub tuaj yeem cuam tshuam loj heev rau kev ruaj khov ntawm cable yog tias tsis tau xav txog zoo thaum xaiv cov khoom siv.
Kev xaiv cov khoom siv sab nraud zoo—txawm yog PVC, PE, lossis LSZH—raws li cov xwm txheej ib puag ncig tshwj xeeb tuaj yeem ua rau lub cable ruaj khov thiab lub neej ua haujlwm ntev dua. Tsis tas li ntawd, kev siv cov txheej txheem thaiv dej kom zoo thiab kev xav txog qib IP ntxiv ua rau kev tiv thaiv cable muaj zog dua hauv cov chaw muaj kev nyuaj.
Los ntawm kev soj ntsuam xyuas cov kev tiv thaiv ib puag ncig no, cov kab ke cable tuaj yeem ua kom zoo dua rau lawv cov ntawv thov, txo cov kev xav tau kev saib xyuas, txo qis kev pheej hmoo ntawm kev ua tsis tiav, thiab ua kom muaj kev ua haujlwm txhim khu kev qha thoob plaws lawv lub neej xav tau.
