濾材孔徑是沿直徑方向呈梯度分布既能從里句外逐漸變小,也能從外向裡逐漸變小,根據(jù)不同介質(zhì)的過濾需要而定。
在過濾過程中,大孔徑部分能以足夠的空容納大顆粒,確保0660D003BN/HC賀德克液壓油濾芯不至于迅速堵塞,同時提供了良好的形狀剛性，小孔徑部分可阻擋細(xì)小顆粒,確保了過濾精庋,從而避免了糟度高的0660D003BN/HC賀德克液壓油濾芯堵塞快、也是壽命短的弊病,而且還降低了過濾阻力,減少了能耗,提高了0660D003BN/HC賀德克液壓油濾芯的使用壽命.定量材分為快速、中速和慢速三種,其孔徑分別大約是1~3微米、10~30微米、80~120微米等。
定量濾紙有一種特殊的用途。在過后,要稱量沉淀的質(zhì)量,這種情況就要用定量濾紙,因為把濾渣從濾紙上轉(zhuǎn)移下來比較困難,且損失的較大,所以分析化學(xué)中一般采用把濾紙燒掉再稱量的方法。所以定量濾紙對燃燒后余的灰分的質(zhì)量有嚴(yán)格的要求,而定性紙則沒有相關(guān)的指標(biāo)要求。
