3、降性最好；對于經(jīng)偶聯(lián)劑3#改性的400目、600目、800目微晶白云母，800目微晶白云母在環(huán)氧樹脂中的沉降性最好，說明粉體顆粒粒度越小，在環(huán)氧樹脂中的沉降速度越慢。(3)采用三電極系統(tǒng)測試微晶白云母絕緣灌注膠的電性能，采用sem測試分析膠片的顯微結(jié)構(gòu)，采用紅外測試微晶白云母在絕緣灌注膠中結(jié)合狀態(tài)，結(jié)果表明：不同偶聯(lián)劑改性微晶白云母制備的絕緣灌注膠均具有良好的絕緣性能；微晶白云母經(jīng)不同偶聯(lián)劑改性后在絕緣灌注膠中分散更加均勻，與環(huán)氧樹脂基體結(jié)合更加緊密；紅外測試不能有效地說明偶聯(lián)劑與有機(jī)基體之間是否形成化學(xué)鍵合，吸收峰強(qiáng)度的變化可能是因?yàn)榕悸?lián)劑的引入使某些基團(tuán)的數(shù)量發(fā)生變化所致。【英文摘要】 m
