Qhov Cuam Tshuam Tseem Ceeb ntawm Cov Txheej Txheem Qhwv Cable rau Kev Ua Haujlwm Tiv Thaiv Hluav Taws

Qhov kev tiv thaiv hluav taws ntawm cov cables yog qhov tseem ceeb thaum muaj hluav taws, thiab kev xaiv cov khoom siv thiab kev tsim qauv ntawm cov txheej qhwv cuam tshuam ncaj qha rau kev ua haujlwm tag nrho ntawm cov cable. Cov txheej qhwv feem ntau muaj ib lossis ob txheej ntawm daim kab xev tiv thaiv qhwv ib puag ncig lub rwb thaiv tsev lossis sab hauv ntawm tus neeg xyuas pib, muab kev tiv thaiv, buffering, thermal rwb thaiv tsev, thiab tiv thaiv kev laus. Cov hauv qab no tshawb nrhiav qhov cuam tshuam tshwj xeeb ntawm cov txheej qhwv rau kev tiv thaiv hluav taws los ntawm ntau qhov kev xav.

1. Kev Cuam Tshuam ntawm Cov Khoom Siv Uas Kub Tau

Yog tias txheej qhwv siv cov khoom siv uas yooj yim hlawv (xws liDaim kab xev tsis wovenlos yog daim kab xev PVC), lawv cov kev ua tau zoo hauv qhov chaw kub siab cuam tshuam ncaj qha rau qhov hluav taws kub ntawm lub cable. Cov ntaub ntawv no, thaum hlawv thaum muaj hluav taws, tsim qhov chaw deformation rau cov txheej rwb thaiv tsev thiab cov txheej tiv thaiv hluav taws. Lub tshuab tso tawm no ua rau txo qhov kev nias ntawm cov txheej tiv thaiv hluav taws vim muaj kev ntxhov siab kub siab, txo qhov yuav ua rau puas tsuaj rau cov txheej tiv thaiv hluav taws. Tsis tas li ntawd, cov ntaub ntawv no tuaj yeem tiv thaiv cov cua sov thaum lub sijhawm pib ntawm kev hlawv, ncua qhov hloov pauv cua sov mus rau tus neeg xyuas pib thiab tiv thaiv cov qauv cable ib ntus.

Txawm li cas los xij, cov ntaub ntawv uas yooj yim hlawv tau lawv tus kheej muaj peev xwm txwv tsis pub txhim kho qhov tiv thaiv hluav taws ntawm lub cable thiab feem ntau yuav tsum tau siv ua ke nrog cov ntaub ntawv uas tiv taus hluav taws. Piv txwv li, hauv qee cov cables uas tiv taus hluav taws, ib txheej tiv thaiv hluav taws ntxiv (xws lidaim kab xev mica) tuaj yeem ntxiv rau saum cov khoom siv uas yooj yim hlawv kom txhim kho kev tiv thaiv hluav taws tag nrho. Qhov kev tsim ua ke no tuaj yeem sib npaug cov nqi khoom siv thiab kev tswj hwm cov txheej txheem tsim khoom hauv kev siv tiag tiag, tab sis cov kev txwv ntawm cov khoom siv uas yooj yim hlawv tseem yuav tsum tau soj ntsuam kom zoo kom ntseeg tau tias lub cable muaj kev nyab xeeb tag nrho.

2. Kev Cuam Tshuam ntawm Cov Khoom Siv Tiv Thaiv Hluav Taws

Yog tias cov txheej qhwv siv cov khoom siv tiv taus hluav taws xws li daim kab xev iav fiber lossis daim kab xev mica, nws tuaj yeem txhim kho qhov ua tau zoo ntawm cov xov hlau. Cov ntaub ntawv no tsim cov nplaim taws tiv taus thaum kub siab, tiv thaiv cov txheej rwb thaiv tsev los ntawm kev sib cuag ncaj qha nrog cov nplaim taws thiab ncua cov txheej txheem yaj ntawm cov rwb thaiv tsev.
Txawm li cas los xij, nws yuav tsum tau sau tseg tias vim yog qhov kev ua haujlwm nruj ntawm cov txheej qhwv, qhov kev ntxhov siab ntawm cov txheej rwb thaiv tsev thaum lub sijhawm kub siab yaj yuav tsis raug tso tawm sab nraud, ua rau muaj kev cuam tshuam loj heev rau cov txheej tiv thaiv hluav taws. Qhov kev cuam tshuam ntawm kev ntxhov siab no tshwj xeeb tshaj yog pom tseeb hauv cov qauv hlau uas muaj hlau tiv thaiv, uas yuav txo qhov kev ua tau zoo ntawm kev tiv thaiv hluav taws.

Yuav kom sib npaug ob qho kev xav tau ntawm kev siv tshuab nruj thiab kev cais hluav taws, ntau yam khoom siv tiv taus hluav taws tuaj yeem nkag mus rau hauv kev tsim txheej qhwv, thiab qhov nrawm ntawm kev sib tshooj thiab kev nruj ntawm kev qhwv tuaj yeem hloov kho kom txo qhov cuam tshuam ntawm kev ntxhov siab rau txheej tiv taus hluav taws. Tsis tas li ntawd, kev siv cov khoom siv tiv taus hluav taws yooj ywm tau maj mam nce ntxiv hauv xyoo tas los no. Cov ntaub ntawv no tuaj yeem txo qhov teeb meem kev ntxhov siab thaum ua kom ntseeg tau tias muaj kev ua haujlwm cais hluav taws, pab txhawb rau kev txhim kho kev tiv taus hluav taws tag nrho.

3. Kev Ua Haujlwm Tiv Thaiv Hluav Taws Kub ntawm Calcined Mica Daim Kab Xev

Daim kab xev mica calcined, ua ib yam khoom siv qhwv zoo, tuaj yeem ua rau lub cable tiv taus hluav taws tau zoo dua. Cov khoom siv no tsim lub plhaub tiv thaiv muaj zog thaum kub siab, tiv thaiv cov nplaim taws thiab cov pa kub siab kom tsis txhob nkag mus rau hauv thaj chaw ntawm tus neeg xyuas hluav taws xob. Cov txheej tiv thaiv ntom ntom no tsis yog tsuas yog cais cov nplaim taws xwb tab sis kuj tiv thaiv kev oxidation ntxiv thiab kev puas tsuaj rau tus neeg xyuas hluav taws xob.

Daim kab xev mica calcined muaj qhov zoo rau ib puag ncig, vim nws tsis muaj fluorine lossis halogens thiab tsis tso cov pa phem thaum hlawv, ua tau raws li cov kev xav tau ib puag ncig niaj hnub no. Nws qhov kev ywj pheej zoo heev ua rau nws hloov kho rau cov xwm txheej nyuaj ntawm kev txuas hluav taws xob, txhim kho qhov kub ntawm cov cable, ua rau nws tsim nyog rau cov tsev siab thiab kev thauj mus los ntawm tsheb ciav hlau, qhov twg xav tau kev tiv thaiv hluav taws kub siab.

4. Qhov Tseem Ceeb ntawm Kev Tsim Qauv

Tus qauv tsim ntawm cov txheej qhwv yog qhov tseem ceeb rau qhov tiv taus hluav taws ntawm lub cable. Piv txwv li, kev siv cov qauv qhwv ntau txheej (xws li ob txheej lossis ntau txheej calcined mica daim kab xev) tsis yog tsuas yog ua kom muaj kev tiv thaiv hluav taws xwb tab sis kuj muab kev tiv thaiv cua sov zoo dua thaum muaj hluav taws. Tsis tas li ntawd, kev xyuas kom meej tias qhov sib tshooj ntawm cov txheej qhwv tsis tsawg dua 25% yog ib qho tseem ceeb los txhim kho kev tiv taus hluav taws tag nrho. Qhov sib tshooj tsawg yuav ua rau muaj cua sov xau, thaum qhov sib tshooj siab yuav ua rau lub cable ruaj khov dua, cuam tshuam rau lwm yam kev ua tau zoo.

Hauv cov txheej txheem tsim, qhov sib xws ntawm cov txheej qhwv nrog lwm cov qauv (xws li lub plhaub sab hauv thiab cov txheej hlau ua rog) kuj yuav tsum tau xav txog. Piv txwv li, hauv cov xwm txheej kub siab, kev qhia txog cov txheej txheem buffer khoom siv tau yooj yim tuaj yeem ua rau muaj kev ntxhov siab thermal nthuav dav thiab txo qhov puas tsuaj rau cov txheej tiv thaiv hluav taws. Lub tswv yim tsim ntau txheej no tau siv dav hauv kev tsim cov cable tiag tiag thiab qhia txog qhov zoo tseem ceeb, tshwj xeeb tshaj yog hauv kev lag luam siab ntawm cov cables tiv thaiv hluav taws.

5. Xaus Lus

Kev xaiv cov khoom siv thiab kev tsim qauv ntawm cov txheej qhwv cable ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm tiv thaiv hluav taws ntawm cable. Los ntawm kev xaiv cov khoom siv zoo (xws li cov khoom siv tiv thaiv hluav taws yooj ywm lossis daim kab xev calcined mica) thiab ua kom zoo dua qhov kev tsim qauv, nws muaj peev xwm txhim kho qhov kev ua haujlwm nyab xeeb ntawm cable thaum muaj hluav taws thiab txo qhov kev pheej hmoo ntawm kev ua haujlwm tsis zoo vim hluav taws. Kev ua kom zoo dua ntawm kev tsim txheej qhwv hauv kev txhim kho cov thev naus laus zis cable niaj hnub muab kev lees paub txog kev ua haujlwm zoo dua thiab cov cables tiv thaiv hluav taws zoo dua.
