Cov Txheej Txheem Tsim Khoom Siv Refractory Cable

1. Mica daim kab xev mineral insulated corrugated tooj liab sheathed cable

Mica daim kab xev rwb thaiv tsev corrugated tooj liab sheathed cable yog ua los ntawm tooj liab conductor, mica daim kab xev rwb thaiv tsev thiab tooj liab sheathed ua ke, nrog kev ua tau zoo hluav taws, ntev txuas ntxiv mus, muaj peev xwm overload, kev lag luam zoo thiab lwm yam.

Cov txheej txheem tsim khoom ntawm mica daim kab xev mineral rwb thaiv tsev corrugated tooj liab sheathed cable pib nrog kev txuas ntxiv annealing ntawm tooj liab hlau lossis tooj liab pas nrig, ntau txoj hlua ntawm tooj liab hlau yog twisted, tus neeg xyuas pib yog qhwv nrog kub siab resistantdaim kab xev mica hluavtaws(daim kab xev calcined mica siv tau rau cov khoom tsis muaj halogen, pa luam yeeb tsawg thiab cov khoom tsis muaj tshuaj lom), txheej rwb thaiv tsev yog puv nrog cov iav fiber tsis-alkali, thiab cov xov hlau yog qhwv nrog cov kab xev kub siab tiv taus cov khoom siv mica los tsim ib txheej tiv thaiv. Lub plhaub tooj liab yog welded rau hauv cov yeeb nkab tooj liab tom qab daim kab xev tooj liab yog qhwv ntev, thiab tom qab ntawd tsim los ntawm kev dov corrugated tas mus li. Cov kev xav tau tshwj xeeb ntawm lub plhaub hlau tsis tuaj yeem raug nthuav tawm, thiab ib txheej ntawm polyolefin (pa luam yeeb tsawg halogen-dawb) sheath tuaj yeem ntxiv sab nraud.

Piv nrog cov xov hlau magnesium oxide uas muaj cov hlau rwb thaiv tsev, cov khoom siv mica uas muaj cov hlau rwb thaiv tsev corrugated tooj liab uas muaj cov hlau rwb thaiv tsev, ntxiv rau qhov ua tau zoo ntawm hluav taws kuj ze heev, tuaj yeem ua tiav qhov ntev ntev ntev, tsis pub dhau 95 mm² kuj tseem tuaj yeem ua rau cov xov hlau ntau lub hauv paus, kom kov yeej qhov tsis zoo ntawm cov xov hlau loj. Txawm li cas los xij, cov yeeb nkab tooj liab corrugated yooj yim tawg, extrusion deformation thiab ib qho rwb thaiv tsev mica, uas kuj tau dhau los ua qhov tsis zoo ntawm cov qauv, thiab qhov xav tau ntawm cov txheej txheem teeb tsa tseem siab heev.

Qhov chaw tswj hwm ntawm mica daim kab xev mineral insulated corrugated tooj liab sheathed cable yog xaiv cov khoom siv kub mica siv thiab vuam thiab dov cov txheej txheem ntawm tooj liab sheathed cable. Kev xaiv cov khoom siv kub mica daim kab xev ncaj qha cuam tshuam rau kev ua haujlwm hluav taws kub ntawm cov khoom. Ntau dhau mica daim kab xev yuav ua rau cov khoom pov tseg, thiab tsawg dhau yuav tsis ua tiav kev ua haujlwm hluav taws kub. Yog tias qhov vuam ntawm lub tsho tooj liab tsis muaj zog, qhov vuam ntawm cov yeeb nkab tooj liab corrugated yooj yim tawg, tib lub sijhawm, qhov tob ntawm kev dov kuj yog qhov tseem ceeb rau kev tswj hwm cov txheej txheem, qhov sib txawv ntawm qhov tob ntawm kev dov thiab lub suab ntawm lub tsho tooj liab yuav ua rau qhov sib txawv ntawm thaj chaw hla ntawm lub tsho tooj liab, yog li cuam tshuam rau qhov tsis kam ntawm lub tsho tooj liab.

2. Cov roj hmab silicone ua los ntawm cov av nplaum (mineral) uas muaj cov rwb thaiv tsev refractory cable

Cov roj hmab silicone ua los ntawm cov khoom siv ceramicCov xov hluav taws kub uas muaj cov pob zeb hauv av yog ib hom xov hluav taws tshiab uas tsis muaj hluav taws, nws cov txheej rwb thaiv tsev thiab cov pa oxygen siv cov khoom siv roj hmab ceramic silicone, cov khoom siv yog mos li cov roj hmab silicone ib txwm nyob rau hauv qhov kub ib txwm, thiab yuav tsim cov plhaub tawv ceramic nyob rau hauv qhov kub siab ntawm 500 ℃ thiab siab dua. Tib lub sijhawm, kev ua haujlwm rwb thaiv tsev raug tswj hwm, thiab cov kab cable tseem tuaj yeem ua haujlwm ib txwm rau ib lub sijhawm thaum muaj hluav taws, yog li pab cawm neeg ua haujlwm thiab txo cov neeg raug mob thiab cov khoom poob ntau li ntau tau.

Cov roj hmab ceramic silicone uas muaj cov khoom siv hluav taws xob rwb thaiv tsev uas muaj cov txheej rwb thaiv tsev refractory (ceramic silicone roj hmab composite khoom) ua lub hauv paus cable, ntawm lub hauv paus cable muaj cov txheej tiv taus kub siab, xws li cov khoom siv roj hmab ceramic silicone, thiab ib txheej tiv thaiv ntxiv, uas yog cov txheej sab nraud ntawm cov cable. Cov khoom no yog tus yam ntxwv los ntawm cov txheej rwb thaiv tsev refractory yog ua los ntawm cov roj hmab ceramic refractory, thiab lub plhaub tawv uas tsim tom qab ablation tseem muaj cov rwb thaiv tsev hluav taws xob, uas tuaj yeem tiv thaiv cov kab xa xov thiab cov kab faib tawm ntawm kev yaig hluav taws, kom ntseeg tau tias muaj kev ntws zoo ntawm lub zog thiab kev sib txuas lus, thiab yeej lub sijhawm cawm neeg tseem ceeb rau kev tshem tawm thiab cawm cov neeg ua haujlwm thaum muaj hluav taws. Cov khoom siv hluav taws xob ceramic feem ntau suav nrog cov roj hmab ceramic hluav taws kub, daim kab xev ceramic hluav taws kub thiab cov hlua ceramic hluav taws kub.

Cov roj hmab silicone ceramic ntawm chav tsev kub tsis muaj tshuaj lom, tsis muaj saj, nrog qhov mos mos thiab elasticity zoo, ntawm qhov kub siab tshaj 500 ° C, nws cov khoom organic hauv lub sijhawm luv luv mus rau hauv cov khoom zoo li ceramic, tsim cov txheej txheem rwb thaiv tsev zoo, thiab nrog kev loj hlob ntawm lub sijhawm hlawv, kub nce, nws qhov nyuaj yog qhov pom tseeb dua. Cov roj hmab silicone ceramic kuj muaj cov khoom siv zoo thiab tuaj yeem ua tiav hauv cov kab ntau lawm vulcanization txuas ntxiv. Qhov sib txawv thiab rwb thaiv tsev ntawm cov cable yog cov roj hmab silicone ceramic, uas tiv thaiv cov pa oxygen, thiab lub plhaub interlocking siv los tsim cov raj serpentine yooj ywm, uas tuaj yeem tiv taus lub zog radial thiab tiv thaiv cov cable los ntawm kev puas tsuaj sab nraud.

Cov ntsiab lus tswj tseem ceeb ntawm cov txheej txheem tsim khoom ntawm cov roj hmab ceramic silicone uas muaj cov rwb thaiv tsev refractory cable feem ntau yog nyob rau hauv cov txheej txheem vulcanization thiab interlocking armoring ntawm cov roj hmab ceramic silicone.

Cov roj hmab silicone ceramic yog cov khoom tseem ceeb ntawm cov roj hmab silicone kub (HTV), uas yog, methyl vinyl silicone roj hmab 110-2 ntxiv xws li cov roj carbon dawb, roj silicone, hmoov porcelain thiab lwm yam khoom ntxiv tom qab sib tov thiab tom qab ntawd ntxiv rau lub tshuab vulcanization ob chav 24, tsis muaj vulcanized rau cov khoom dawb nplaum, tsis zoo formability, xav tau qhov kub extruder kom tswj tau qee qhov kub qis, thaum siab dua qhov kub no, Yuav muaj qhov tshwm sim ntawm cov kua nplaum siav, ua rau degumming thiab puas tsuaj rau txheej rwb thaiv tsev. Tsis tas li ntawd, vim yog qhov tsis zoo ntawm cov roj hmab silicone ceramic, nws tsis tuaj yeem nqa los ntawm lub hau mus rau hauv cov kua nplaum, ua rau qhov sib txawv hauv cov khoom siv kua nplaum hauv lub hau, uas tseem yuav ua rau qhov tshwm sim ntawm degumming. Yuav kom tsis txhob muaj cov teeb meem saum toj no, yuav ua li cas teeb tsa cov cuab yeej sib xws rau lub extruder, yuav ua li cas tswj qhov kub qis ntawm lub extruder, thiab yuav ua li cas ua cov khoom siv roj hmab hauv lub hau tsis muaj qhov sib txawv tau dhau los ua qhov tseem ceeb los xyuas kom meej qhov zoo ntawm cov txheej rwb thaiv tsev.

Kev sib txuas ua ke ntawm cov cuab yeej ua los ntawm cov hlau uas muaj cov hlua khi tsis yog tus qauv. Yog li ntawd, thaum tsim khoom, yuav ua li cas teeb tsa cov pwm tsim nyog raws li cov lus qhia sib txawv, qhov dav thiab tuab ntawm cov kab txaij siv rau kev sib txuas ua ke yog qhov tseem ceeb los tsim cov teeb meem txheej txheem xws li tsis muaj lub buckle nruj.
