Cov tshuab hluav taws xob niaj hnub no cia siab rau kev sib txuas ntawm cov khoom siv sib txawv, lub rooj tsav xwm hauv Circuit Court, thiab cov khoom siv hluav taws xob. Txawm hais tias kev xa hluav taws xob lossis hluav taws xob teeb liab, cables yog cov pob txha ntawm kev sib txuas, ua rau lawv yog ib feem tseem ceeb ntawm txhua lub tshuab.
Txawm li cas los xij, qhov tseem ceeb ntawm cov tsho cable (cov txheej txheej sab nraud uas nyob ib puag ncig thiab tiv thaiv cov neeg ua haujlwm sab hauv) feem ntau underestimated. Xaiv cov khoom siv lub tsho cable zoo yog qhov kev txiav txim siab tseem ceeb hauv kev tsim thiab kev tsim khoom, tshwj xeeb tshaj yog thaum siv nyob rau hauv ib puag ncig hnyav. Kev nkag siab txog qhov sib npaug ntawm kev ua haujlwm ntawm kev ua haujlwm, kev tiv thaiv ib puag ncig, yoog raws, tus nqi, thiab kev tswj hwm kev ua raws cai yog qhov tseem ceeb rau kev xaiv zoo.
Nyob rau hauv lub plawv ntawm lub tsho cable yog ib daim ntaub thaiv npog uas tiv thaiv thiab ua kom lub neej thiab kev ntseeg siab ntawm cov kab hauv sab hauv. Qhov kev tiv thaiv no tiv thaiv kev ya raws, tshuaj lom neeg, hluav taws xob UV, thiab kev ntxhov siab ntawm lub cev xws li kev puas tsuaj thiab cuam tshuam.
Cov khoom siv rau lub tsho cable yog los ntawm cov yas yooj yim mus rau cov polymers siab heev, txhua tus muaj cov khoom tshwj xeeb kom tau raws li cov kev xav tau ntawm ib puag ncig thiab kev siv tshuab. Cov txheej txheem xaiv yog qhov tseem ceeb vim tias cov khoom siv zoo ua kom pom kev ua tau zoo thiab kev tiv thaiv raws li qhov xav tau ntawm kev siv.
Tsis muaj "ib qho me me haum rau tag nrho" kev daws teeb meem rau cov tsho cable. Cov khoom siv xaiv tuaj yeem sib txawv heev nyob ntawm qhov xwm txheej tshwj xeeb ntawm daim ntawv thov.
Muaj ntau ntau yam uas yuav tsum tau xav txog thaum xaiv cov khoom siv lub tsho cable zoo.
1. Cov xwm txheej ib puag ncig
Tshuaj tiv thaiv yog ib qho tseem ceeb hauv kev xaiv cov tsho cable, vim tias cov cables yuav ntsib cov roj, cov kuab tshuaj, cov kua qaub, lossis cov hauv paus, nyob ntawm lawv daim ntawv thov. Ib lub tsho cable uas tau xaiv zoo tuaj yeem tiv thaiv kev degradation lossis corrosion ntawm nws cov hauv paus ntsiab lus, yog li tswj kev ncaj ncees ntawm cable hla nws lub neej kev pabcuam. Piv txwv li, nyob rau hauv kev lag luam ib puag ncig uas muaj tshuaj lom neeg raug, nws yog ib qho tseem ceeb rau xaiv cov ntaub ntawv uas muaj peev xwm tiv taus tej yam hnyav. Ntawm no, cov tshuaj tshwj xeeb uas cov cable yuav raug tshuaj xyuas yuav tsum raug soj ntsuam, vim qhov no txiav txim siab qhov xav tau ntawm cov khoom tshwj xeeb xws li fluoropolymer kom ua tiav cov tshuaj tiv thaiv huab cua.
Huab cua thiab hnub ci tiv thaiv yog lwm qhov tseem ceeb, tshwj xeeb tshaj yog rau cov kab hluav taws xob siv sab nraum zoov. Kev raug tshav ntuj ntev ntev tuaj yeem ua rau cov khoom siv tsis muaj zog, ua rau brittleness thiab tsis ua tiav. Cov ntaub ntawv tsim los tiv thaiv UV hluav taws xob kom ntseeg tau tias lub cable tseem ua haujlwm thiab ruaj khov txawm tias nyob hauv tshav ntuj hnyav. Rau cov ntawv thov no, cov ntaub ntawv zoo tshaj plaws yog CPE thermoplastics, CPE thermostats, lossis EPR thermostats. Lwm yam khoom siv siab heev, xws li hla-txuas polyethylene (XLPE), tau tsim los muab kev txhim kho UV tiv thaiv, ua kom lub neej ntev ntawm cov kab hauv kev siv sab nraum zoov.
Tsis tas li ntawd, nyob rau hauv ib puag ncig uas muaj kev pheej hmoo ntawm hluav taws yog ib qho kev txhawj xeeb, xaiv lub tsho cable uas yog nplaim hluav taws kub los yog tua tus kheej tuaj yeem yog qhov kev xaiv cawm txoj sia. Cov ntaub ntawv no yog tsim los tiv thaiv kev sib kis ntawm cov nplaim taws, ntxiv txheej txheej tseem ceeb ntawm kev nyab xeeb hauv cov ntawv thov tseem ceeb. Rau nplaim retardancy, cov kev xaiv zoo muaj xws liPVCThermoplastics thiab CPE thermoplastics. Cov ntaub ntawv zoo li no tuaj yeem ua kom cov nplaim taws qeeb qeeb thaum txo cov pa tawm ntawm cov pa phem thaum lub sij hawm combustion.
2. Mechanical Properties
Kev puas tsuaj, kev cuam tshuam quab yuam, thiab kev sib tsoo muaj peev xwm ntawm lub tsho cable ncaj qha cuam tshuam rau kev ua haujlwm ntawm polyurethane. Qhov no yog qhov tsim nyog tshaj plaws hauv cov ntawv thov uas cov cable hla dhau qhov nyuaj los yog yuav tsum tau tuav ntau zaus. Hauv cov ntawv thov mobile heev, xws li hauv cov neeg hlau lossis cov tshuab tsis muaj zog, xaiv lub tsho cable nrog cov khoom siv zoo tshaj plaws tuaj yeem pab kom tsis txhob muaj kev hloov pauv thiab tu. Cov ntaub ntawv hnav-tiv taus zoo tshaj plaws rau lub tsho npog suav nrog polyurethane thermoplastics thiab CPE thermoplastics.
3. Kev ntsuas kub
Kev khiav hauj lwm kub ntawm cov khoom siv cable tsho tuaj yeem yog qhov sib txawv ntawm kev ua tiav lossis tsis ua haujlwm rau lub kaw lus. Cov ntaub ntawv uas tsis tuaj yeem tiv taus qhov kub thiab txias ntawm lawv qhov chaw ib puag ncig tuaj yeem ua rau nkig hauv qhov txias txias lossis degrade thaum raug kub. Qhov kev degradation no tuaj yeem cuam tshuam qhov kev ncaj ncees ntawm cable thiab ua rau hluav taws xob rwb thaiv tsev tsis ua haujlwm, ua rau muaj kev cuam tshuam rau kev ua haujlwm lossis kev nyab xeeb.
Txawm hais tias muaj ntau tus qauv cables yuav raug ntsuas txog li 105 ° C, tshwj xeeb PVC daim ntaub ntawv yuav tsum tau tiv taus kub dua. Rau kev lag luam xws li roj thiab roj, cov ntawv thov tshwj xeeb xav tau cov ntaub ntawv, xws li ITT Cannon's SJS series cov ntaub ntawv, uas tuaj yeem tiv taus kub txog 200 ° C. Rau cov kub kub no, muaj ntau yam khoom siv yuav tsum tau txiav txim siab, suav nrog PVC ntawm lub thermoplastic sab thiab CPE lossis EPR lossis CPR ntawm lub ntsuas kub. Cov ntaub ntawv uas tuaj yeem ua haujlwm nyob rau hauv ib puag ncig zoo li no tuaj yeem tiv taus qhov kub thiab txias thiab tiv thaiv thermal aging, kom ntseeg tau tias qhov kev ua tau zoo ntawm cov cable dhau sijhawm.
Xav txog qhov kub thiab txias ib puag ncig, xws li onshore drilling rigs. Nyob rau hauv cov high-pressure, high-temperature ib puag ncig, nws yog tsim nyog los xaiv ib tug cable tsho ntaub ntawv uas yuav tiv taus huab cua kub yam tsis muaj degrading los yog ua tsis tau tejyam. Thaum kawg, xaiv cov khoom siv cable tsho zoo tuaj yeem ua kom muaj kev nyab xeeb thiab txhim khu kev qha thaum txuas lub neej ntawm cov khoom siv.
4. Kev xav tau kev hloov pauv
Qee daim ntawv thov xav tau cov cables kom nyob twj ywm nyob rau hauv rov qab khoov thiab twisting txav. Qhov kev xav tau ntawm kev hloov pauv no tsis txo qhov kev xav tau ntawm kev ua haujlwm ntev; Yog li ntawd, cov ntaub ntawv yuav tsum tau ua tib zoo xaiv kom sib npaug ntawm ob qhov kev xav tau no. Nyob rau hauv cov ntaub ntawv no, cov ntaub ntawv xws li thermoplastic elastomers (TPE) los yog polyurethane (PUR) yog nyiam rau lawv elasticity thiab resilience.
Cables siv nyob rau hauv industrial automation, piv txwv li, yuav tsum tau hloov tau yooj yim kom haum rau lub zog ntawm cov tshuab xws li neeg hlau. Mesh robots siv rau kev ua haujlwm xws li xaiv thiab tso qhov chaw yog qhov piv txwv tseem ceeb ntawm qhov xav tau no. Lawv cov qauv tsim tso cai rau ntau qhov kev tawm suab, tso qhov kev ntxhov siab tas li ntawm cov cables, xav tau kev siv cov ntaub ntawv uas tuaj yeem tiv taus kev khoov thiab sib tw yam tsis muaj kev cuam tshuam kev ua haujlwm.
Tom qab txiav txim siab ib puag ncig, cov khoom siv kho tshuab, qhov kub thiab txias, thiab kev xav tau yooj yim, nws tseem ceeb heev uas yuav tsum nco ntsoov tias sab nraud ntawm lub cable yuav txawv nrog txhua yam khoom. Yuav kom nyob twj ywm ib puag ncig, txoj kab uas hla yuav tsum nyob twj ywm nyob rau hauv lub sealing confines ntawm backshell los yog connector txuas.
