導熱灌封膠沉降怎們辦?

導熱灌封膠沉降怎們辦?

導熱灌封膠發(fā)生沉降是一種非常正常的現(xiàn)象,往里面加導熱粉后,基材是硅油,導熱粉的密度高于硅油,油重粉輕,就容易發(fā)生沉降,而且導熱系數(shù)越高,沉降的越快,所以高導熱系數(shù)的灌封膠是否好用,就看多長時間開始發(fā)生沉降和沉降后能否再次……

導熱墊片的自粘性是涂膠才有的嗎,多久時間消失?

導熱墊片的自粘性是涂膠才有的嗎,多久時間消失?

導熱墊片自帶粘性是材料本身特性,原始設(shè)計當中就具備此特點,不是通過涂膠來實現(xiàn)的,不會對材料導熱性能產(chǎn)生影響。在儲存期內(nèi),自粘性不會消失,但會隨著產(chǎn)品老化而消失。自粘型的好處是為了方便操作,與導熱絕緣片系列產(chǎn)品相比,表面帶……

導熱墊片能直接鎖螺絲嗎?

導熱墊片能直接鎖螺絲嗎?

這個問題為了快速作業(yè),在使用中經(jīng)常碰到,答案是否定的,很抱歉!雖然導熱墊片的源頭是硅橡膠,但不是工程塑料,機械強度非常差,由于導熱墊片比較軟,不能直接開孔鎖螺絲固定,這樣會使導熱墊片開裂碎掉,所以建議不要投機取巧,但是可……

AB管快干膠混合后開始固化時為何有點燙手

AB管快干膠混合后開始固化時為何有點燙手

您用的這個快干膠應該是環(huán)氧樹脂體系的AB快干膠,環(huán)氧樹脂膠固化時會放熱,有大量的熱量往外散,所以用手觸碰就是燙手的感覺??旄赡z的固化速度非常快,意味著熱量會迅速爆發(fā)出,與固化慢的環(huán)氧膠相比,會更燙手。還有,釋放的熱量跟混……
