style="text-indent:25px">我們時?？紤]一個問題:電磁屏蔽導(dǎo)電橡膠能與體積電阻一定成正比例嗎?即導(dǎo)電性越好，屏蔽效能越高?據(jù)外國學(xué)者研究發(fā)現(xiàn)，削弱干擾波的方法有三種:屏蔽、吸波和濾波。電磁屏蔽導(dǎo)電橡膠由于其導(dǎo)電顆粒的作用，電子在運(yùn)動過程中，可產(chǎn)生與外界相反的磁場，起到屏蔽的作用。但吸波的原理與屏蔽相似，同樣是用到微觀粒子。當(dāng)填充的導(dǎo)電顆粒達(dá)到納米級別時，不只是達(dá)到粒徑是nm，更重要的是具有較高的比表面積，空隙率，這樣的納米粒子將具有更好的納米效應(yīng)，納米效應(yīng)即可有吸波作用。就是導(dǎo)電顆粒填充的導(dǎo)電橡膠，可起到屏蔽與吸波的作用。電磁屏蔽導(dǎo)電橡膠是經(jīng)濟(jì)實(shí)惠,使用方便的屏蔽材料。中山橡膠絕緣膠帶批發(fā)</p><p
