Dab tsi yog mica board? Cov yam ntxwv thiab kev ua tau zoo yog dab tsi?

Cov kav dej rwb thaiv tsev suav nrog cov kav dej mica, kev qhia txog cov kav dej mica: cov kav dej mica feem ntau yog ua los ntawm cov ntawv zoo tev tawm mica muscovite ntawv lossis phlogopite mica ntawv. Kev kub siab tiv taus cov kav dej mica yog ua los ntawm cov ntawv mica uas tsis muaj cov kua nplaum ua kua nplaum tom qab ci Cov khoom siv thermosetting tubular rwb thaiv tsev yog cov khoom siv tubular rwb thaiv tsev uas muaj cov rwb thaiv tsev zoo.

Daim ntawv thov ntau yam ntawm mica raj: raj mica tuaj yeem siv ua lub bushing thiab lub tes tsho rwb thaiv tsev ntawm cov khoom siv hluav taws xob cua sov uas nws qhov kub siv tiag yog 900 ℃.

Cov tsos: Cov nplaim yog du, tsis muaj txheej, ua npuas thiab tawv, muaj cov cim ntawm kev ua thiab txiav tab sis tsis tshaj qhov ntsuas ntawm phab ntsa tuab kam rau ua, sab hauv phab ntsa muaj pob me me thiab tsis xws luag, thiab ob hnub xaus raug txiav kom zoo.

Cov khoom siv kho tshuab ntawm lub raj mica zoo heev, thiab nws tau siv dav hauv ntau lub cav, lub cev muaj zog, pas nrig hauv cov khoom siv hluav taws xob, thiab cov qhov hluav taws xob tawm. Vim hais tias lub raj mica yog cov khoom siv tubular insulating ua los ntawm tev mica lossis mica ntawv nrog cov nplaum tsim nyog ntawm cov khoom siv ib leeg txhawb ib leeg, thiab tom qab ntawd yob nws.
