Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm mica boards hauv cov khoom sib txawv?

Lub ntsiab tseem ceeb ntawm mica board yog mica. Feem ntau, cov ntsiab lus ntawm mica ntawm lub rooj tsavxwm mica nce mus txog 90 feem pua ​​​​, thiab lwm 10 feem pua ​​​​yog feem ntau yog cov ntaub ntawv xws li kua nplaum. Cov ntawv laminate nruj FR4 epoxy board mica boards peb tsim tuaj yeem tiv taus 500 degree hauv ib puag ncig ua haujlwm ntev thiab 850 degree hauv lub sijhawm luv; Tsis tas li ntawd, peb cov phlogopite tuaj yeem ua haujlwm hauv ib puag ncig ntawm 1000 degree. FR4 epoxy pawg thawj coj ua qhov chaw tau nrov dua, thiab nws qhov kev ua haujlwm tsis zoo yog nyob rau hauv txoj haujlwm tseem ceeb hauv cov khoom.

Cov ntaub ntawv rwb thaiv tsev feem ntau yog cov khoom siv thermal conductivity tsawg dua lossis sib npaug rau 0.2. Cov ntaub ntawv thermal rwb thaiv tsev tau tsim kho sai. Xaiv cov txheej txheem rwb thaiv tsev zoo thiab cov khoom siv hauv kev lag luam thiab kev tsim kho feem ntau tuaj yeem ua ntau dua nrog tsawg dua. Thaum peb cov rwb thaiv tsev siv rau hauv kev tsim kho, txhua tuj ntawm cov ntxhia wool rwb thaiv tsev txuag tau ib tuj roj ib xyoos. Nws txuag cov nqi thiab txo cov nuj nqis.

Mica muaj ntau yam khoom siv lub cev thiab tshuaj lom neeg, xws li kub kub tsis kam, rwb thaiv tsev kub, hluav taws xob tiv thaiv, thiab lwm yam. Yog li ntawd, nws cov khoom ua tiav mica board feem ntau yog siv los ua cov khoom siv insulating rau cov khoom siv hluav taws xob. Mica daim hlau ua los ntawm mica tsis tsuas yog siv rau hluav taws xob rwb thaiv tsev, tab sis kuj siv dav hauv kev lag luam tshuaj xws li cov khoom siv hauv tsev, yas, thiab roj hmab.

Peb nyuaj muscovite motherboard, cov khoom yog silver-dawb, thiab kub-resistant qib yog: FR4 epoxy board ua qhov chaw tuaj yeem tiv taus kub ntawm 500degreeraws li kev ua haujlwm tsis tu ncua thiab 850degreeraws li kev ua haujlwm tsis sib xws.

Peb hardness motherboard, cov khoom yog golden, qhov kub tsis kam yog 850degreerau kev ua haujlwm tas mus li thiab 1050degreerau kev ua haujlwm tsis sib xws.

Zoo heev kub rwb thaiv tsev muaj nuj nqi, siab kub kuj mus txog 1000 fr4 epoxy board ua tiav qhov chawmuaj cov nqi zoo heev hauv cov ntaub ntawv kub rwb thaiv tsev.

Siv dav hauv metallurgy, tshuaj lom neeg kev lag luam, cov khoom siv hauv tsev, xws li tsev neeg qhov cub, toasters, toasters, microwave ncu, plaub hau tshuab, hluav taws xob irons, cua sov rings, plaub hau curlers, hluav taws xob combs, muaj hluav taws xob furnaces, skeleton cov ntaub ntawv ntawm industrial zaus furnaces, refining Rauv, nruab nrab zaus rauv, calcium carbide rauv, ferroalloy, daj phosphorus rauv, hluav taws xob arc rauv, fais fab nroj tsuag, electrolytic aluminium, txhaj tshuaj molding tshuab thiab lwm yam khoom siv hluav taws xob cua sov.

Lub mica board yog ua los ntawm cov ntawv zoo phlogopite mica ntawv thiab cov organic FR4 epoxy board ua ib feem ntawm silica gel, thiab yog sib koom ua ke thiab dov rau hauv cov khoom tsis zoo tubular insulating. Nrog rau cov hluav taws xob rwb thaiv tsev ua haujlwm zoo thiab muaj zog txhua yam, nws yog qhov tsim nyog rau kev rwb thaiv tsev ntawm electrode rods los yog qhov hluav taws xob bushings nyob rau hauv ntau yam khoom siv hluav taws xob thiab motors.
