Hard mica boards yog dav siv nyob rau hauv ntau lub lag luam thiab kev lag luam, feem ntau suav nrog metallurgy, tshuaj lom neeg kev lag luam, khoom siv hauv tsev, thiab lwm yam. Cov ntawv thov tshwj xeeb suav nrog:
Kev lag luam metallurgy: siv los ua cov khoom siv pob txha rau cov khoom siv hluav taws xob xws li cov khoom siv hluav taws xob xws li cov tshuab hluav taws xob, lub tshuab hluav taws xob zaus, cov tshuab ua kom zoo, cov tshuab hluav taws xob nruab nrab, cov khoom siv calcium carbide furnaces, ferroalloys, daj phosphorus furnaces, arc furnaces, thiab lwm yam.
Kev lag luam tshuaj: raws li cov khoom siv insulating rau cov khoom siv hluav taws xob, nws kuj yog siv hauv cov khoom siv hauv tsev, plastics, roj hmab thiab lwm yam lag luam.
Cov khoom siv hauv tsev: cov khoom siv pob txha rau cov khoom siv hluav taws xob xws li toasters, qhov cub, lub khob cij, tshuab plaub hau, hluav taws xob hlau, cua sov coils, thiab lwm yam.
Hard mica boards muaj rwb thaiv tsev zoo heev thiab kub tsis kam, thiab tuaj yeem siv tau ntev ntawm qhov kub ntawm 500-800 degree . Nws cov khoom yog nyiaj-dawb, nrog rau qhov kub thiab txias ntawm 500 degrees thaum lub sijhawm ua haujlwm tas mus li thiab kub tsis kam mus txog 850 degrees thaum lub sijhawm ua haujlwm tsis tu ncua. Mica board yog ua los ntawm cov ntawv zoo phlogopite mica thiab cov organic FR4 epoxy board nrog qee cov txheej txheem silicone, sib koom ua ke thiab dov rau hauv ib qho nyuaj tubular insulating khoom. Nws muaj cov hluav taws xob rwb thaiv tsev zoo heev thiab muaj zog txhua yam, thiab tsim nyog rau kev rwb thaiv tsev ntawm electrode rods lossis qhov hluav taws xob bushings hauv ntau yam khoom siv hluav taws xob thiab lub cev muaj zog.
