Cov ntaub ntawv qhwv thiab sau
Kev qhwv yog hais txog cov txheej txheem ntawm kev qhwv ntau yam hlau lossis cov khoom siv uas tsis yog hlau rau lub hauv paus cable hauv daim ntawv ntawm daim kab xev lossis xov hlau. Kev qhwv yog ib daim ntawv txheej txheem siv dav dav, thiab cov qauv rwb thaiv tsev, kev tiv thaiv thiab kev tiv thaiv txheej txheem yog siv, suav nrog kev qhwv rwb thaiv tsev, qhwv daim kab xev refractory, kev tiv thaiv hlau, kev tsim cable, riam phom, braiding thiab lwm yam.
(1)Daim kab xev tooj liab, daim kab xev tooj liab-yas sib xyaw
Daim kab xev tooj liab thiab daim kab xev tooj liab-yas sib xyaw muaj lawv daim ntawv thov hauv cov xov hluav taws xob. Daim kab xev tooj liab feem ntau yog siv rau txheej hlau tiv thaiv, uas ua lub luag haujlwm ntawm kev tiv thaiv tam sim no thiab kev tiv thaiv hluav taws xob, thiab yuav tsum muaj kev ntshiab siab, cov khoom siv kho tshuab zoo thiab zoo nkauj. Daim kab xev tooj liab-yas sib xyaw yog ua los ntawm daim kab xev tooj liab, ua ke nrog zaj duab xis yas, siv rau kev tiv thaiv kab hlau sib txuas lus, xav tau xim sib xws, nto du thiab tsis muaj kev puas tsuaj, nrog lub zog tensile siab, elongation thiab conductivity.
(2) Daim kab xev txhuas uas muaj yas txheej
Daim kab xev yas txheej txhuas yog cov khoom siv tseem ceeb rau lub zog hluav taws xob, roj av, tshuaj lom neeg thiab lwm yam kev lag luam cable, vim nws cov dej tsis nkag thiab noo noo zoo heev. Nws yog qhwv lossis ntev, thiab khi nrog polyethylene sheath los ntawm kev kub siab thiab kub siab los ua ib qho qauv sib xyaw. Daim kab xev yas txheej txhuas muaj xim txheem, nto du, cov khoom siv kho tshuab zoo heev, lub zog tensile siab thiab kev tiv taus elongation.
(3) Daim kab xev hlau, Hlau hlau
Vim lawv lub zog zoo heev, daim kab xev hlau thiab hlau hlau tau siv dav hauv cov txheej txheem ua rog thiab lwm yam khoom siv thauj khoom hauv cov xov hlau uas ua lub luag haujlwm tiv thaiv kev ua haujlwm. Daim kab xev hlau yuav tsum tau galvanized, tinned lossis pleev xim kom txhim kho kev tiv thaiv xeb. Cov txheej galvanized tuaj yeem passivated hauv huab cua thiab muaj kev ruaj khov siab, thaum nws tuaj yeem txi nws tus kheej los tiv thaiv cov txheej hlau thaum nws ntsib dej. Raws li cov khoom siv armored, hlau hlau yog qhov tseem ceeb hauv cov sijhawm tseem ceeb xws li hla dej thiab dej hiav txwv, ntev-ntev overhead tso. Txhawm rau txhim kho kev tiv thaiv xeb ntawm cov hlau hlau, cov hlau hlau feem ntau yog galvanized lossis coated nrog high-density polyethylene. Stainless acid-resistant hlau hlau muaj kev tiv thaiv xeb siab dua thiab cov khoom siv kho tshuab, tsim nyog rau cov hlau tshwj xeeb thiab cable.
Daim kab xev tsis-woven tseem hu ua daim ntaub tsis-woven, uas yog ua los ntawm cov fiber hluavtaws ua lub cev tseem ceeb los ntawm kev sib txuas ua ke, uas polyester fiber yog qhov siv ntau tshaj plaws. Haum rau kev qhwv lossis txheej ntawm cov cables. Cov tsos ntawm kev faib tawm fiber yog sib xws, tsis muaj pwm, cov khoom tsis huv thiab qhov, tsis muaj kab nrib pleb hauv qhov dav, qhuav thiab tsis ntub.
(5) Daim kab xev tiv taus hluav taws
Cov ntaub nplaum hluav taws tau muab faib ua ob pawg: cov ntaub nplaum hluav taws thiab cov ntaub nplaum hluav taws kub, uas tuaj yeem tswj tau hluav taws xob rwb thaiv tsev hauv qab nplaim taws, xws li cov ntaub nplaum mica thiab cov ntaub nplaum ceramic refractory composite; Cov ntaub nplaum hluav taws kub, xws li cov iav ribbon, tuaj yeem tiv thaiv kev kis hluav taws. Cov ntaub nplaum mica refractory nrog cov ntawv mica ua nws lub hauv paus muaj cov khoom hluav taws xob zoo heev thiab tiv taus kub siab.
Cov ntaub nplaum ua los ntawm cov khoom siv ceramic refractory ua rau muaj kev tiv thaiv hluav taws los ntawm kev hlawv rau hauv cov txheej rwb thaiv tsev ceramic. Cov ntaub nplaum fiber iav nrog nws cov yam ntxwv uas tsis kub hnyiab, tiv taus cua sov, rwb thaiv hluav taws xob thiab lwm yam, feem ntau siv rau hauv cov txheej tiv thaiv hluav taws xob cable, los muab kev lees paub zoo rau kev nyab xeeb ntawm cable.
Daim kab xev thaiv dej no yog ua los ntawm ob txheej ntawm cov ntaub polyester fiber uas tsis yog woven thiab cov khoom siv uas nqus tau dej zoo heev. Thaum dej nkag mus, cov khoom siv uas nqus tau dej yuav nthuav dav sai sai kom puv qhov sib txawv ntawm cov xov hlau, ua kom tsis txhob muaj dej nkag mus thiab nthuav dav ntxiv. Cov khoom siv uas nqus tau dej ntau feem ntau suav nrog carboxymethyl cellulose, thiab lwm yam, uas muaj hydrophilicity zoo heev thiab khaws dej tau zoo thiab tsim nyog rau kev tiv thaiv dej ntawm cov xov hlau.
(7) Cov khoom siv sau
Cov ntaub ntawv sau cable muaj ntau yam, thiab qhov tseem ceeb yog kom ua tau raws li qhov yuav tsum tau ua ntawm kev tiv taus kub, tsis-hygroscopic thiab tsis muaj kev tsis zoo nrog cov ntaub ntawv sib cuag cable. Polypropylene hlua yog siv dav vim nws cov khoom ruaj khov thiab tshuaj lom neeg, lub zog siab thiab tiv taus kub zoo. Cov yas ntim khoom ua ntej yog ua los ntawm kev siv cov yas pov tseg, uas yog tus phooj ywg ib puag ncig thiab kev lag luam. Hauv cov cables hluav taws thiab hluav taws-resistant, asbestos hlua yog siv dav rau nws qhov kev tiv taus kub zoo heev thiab hluav taws retardant, txawm hais tias nws qhov ceev siab ua rau tus nqi nce.
