Kev ua tau zoo ntawm mica daim kab xev

As the main raw material of fire-resistant cables, mica tape should have its product standards. The technical conditions for the specified performance indicators and test methods of mica tape products fully reflect the objective and practical needs. It is necessary for the electrical performance of mica tape to be assessed at the same time by the two indicators of insulation resistance value and withstand voltage at high temperature. Due to the large variety of fire-resistant cables, the entire insulation system (including conductor-to-conductor and conductor-to-shielding systems) ) There are certain requirements. When the insulation resistance drops to a certain value, even if there is no insulation breakdown, the entire circuit system will lose its normal operation function. For the quality of fire-resistant cables, the quality of mica tape is the key to its “fire-resistant” function.

Mica daim kab xev muaj qhov kub thiab txias tsis kam tiv taus thiab tiv taus kev kub hnyiab. Mica daim kab xev muaj qhov hloov pauv tau zoo nyob rau hauv ib txwm muaj xwm txheej thiab tsim nyog rau txheej txheej tiv thaiv hluav taws tseem ceeb ntawm ntau yam xaim hluav taws-tiv taus xaim thiab xaim hluav taws xob. Txij li mica daim kab xev siv cov organic silicone nplaum xim nrog kev ua tau zoo raws li cov nplaum, tsis muaj qhov tsis muaj pa taws ua rau muaj kev phom sij thaum nws raug hlawv hauv qhov qhib nplaim taws. Yog li ntawd, mica daim kab xev tsis tsuas yog siv tau rau cov hluav taws-tiv taus cov xov hlau thiab cov hlua, tab sis kuj muaj kev nyab xeeb heev.

mica daim kab xev tuaj yeem ua tau raws qee qhov kev xav tau ntawm cov tshuab hluav taws xob siab, yog li nws tau siv dav. Nrog kev nce qib theem ntawm lub cev muaj zog, kev txhim kho tas li ntawm lub peev xwm thiab kev txhim kho tas mus li ntawm kev ua haujlwm siab, qhov yuav tsum tau ua rau rwb thaiv tsev ntawm lub cav kuj tseem txhim kho tas li, thiab kev tshawb fawb ntawm cov khoom siv rwb thaiv tsev tseem tab tom ua. Cov kab xev mica yog ua los ntawm cov ntawv mica raws li cov khoom siv raw, thiab ob tog lossis ib leeg ib leeg yog ua los ntawm cov tshuab hluav taws xob uas tsis muaj iav alkali dawb thiab zaj duab xis polyester lossis zaj duab xis polyimide lossis zaj duab xis tiv thaiv kab mob raws li txhawb cov ntaub ntawv los ntawm cov txheej txheem tshwj xeeb . Raws li tus qauv, nws tau muab faib ua: daim kab xev ob tog, ib daim kab xev ib leeg, peb-hauv-ib daim kab xev, ob kab xev zaj duab xis, ib daim kab xev zaj duab xis, thiab lwm yam Raws li mica, nws tuaj yeem faib ua: cov khoom siv hluavtaws , phlogopite daim kab xev, thiab muscovite daim kab xev.

Hluav taws tuaj yeem tshwm sim nyob txhua qhov chaw, tab sis thaum hluav taws tshwm sim hauv qhov chaw uas muaj cov pejxeem coob thiab xav tau kev nyab xeeb siab, nws yog ib qho tseem ceeb heev kom ntseeg tau tias lub zog thiab cov ntaub ntawv xov tooj tswj hwm kev ua haujlwm ib txwm rau lub sijhawm txaus, txwv tsis pub nws yuav ua rau muaj kev puas tsuaj loj. Yog li ntawd, cov hluav taws hluav taws xob ua hluav taws xob tsim nrog mica daim kab xev tau siv dav hauv cov chaw hauv qab no: roj drilling platforms, cov tsev siab, cov chaw siv hluav taws xob loj, cov tsheb nqaj hlau, cov lag luam tseem ceeb thiab kev lag luam mining, cov chaw siv computer, cov chaw siv dav hlau, chaw sib txuas lus, chaw ua tub rog, thiab cov lag luam tseem ceeb thiab cov lag luam cuam tshuam txog kev nyab xeeb hluav taws thiab cawm hluav taws. Mica daim kab xev muaj kev ua tau zoo tshaj plaws thiab siv tau yooj yim thiab tau dhau los ua cov khoom siv rau cov hluav taws uas tiv taus cov xaim hluav taws xob.
