2. Air flux空氣通量:在不同的壓力、不同的孔率和不同濾器面積情況下,空氣所流過的流量。
3. Bubble point氣泡點:使用特定液體浸潤濾膜,在特定溫度下,所須排擠出濾膜孔中液體的zui小壓力。
4. Hydrophilicity親水性:親水性的濾膜通常有一層特殊化學(xué)層使得濾膜可以被水浸潤; Hydrophobiity 是對水的斥力的一個參考。疏水性濾膜很少*不吸水。在觀察上可目視小水液滴停留在濾膜的表面而不會被表面吸附而擴散成水面。疏水性的大小取決于濾材的孔徑和濾膜原料的特性。
5. 流率和流量:流率是在特定溫度及壓力下單位時間內(nèi)過濾液通過濾膜的總量。流率與濾膜表面性質(zhì)有密切關(guān)系。流率和通量是微孔濾膜性能的二個重要參數(shù)。這種性能取決于以下幾個方面:
1)粘性:粘度決定了液體流動的難易。液體的粘度越高(在一定的溫度和壓力條件下)流率越低。而要達到相同流率時所需的壓力越高。
2)壓力差:過濾中進口與出口的壓力差,當(dāng)濾器的滿負荷時,過濾壓力差增大。
3) Porosity孔率:是指濾膜上所有孔的體積占全部濾膜體積的比例。流率與膜的孔率有直接的關(guān)系。
微孔濾膜的主要功能是從氣相或者液相中截留微粒,細菌及其他雜質(zhì),以達到分離,凈化,提純的目的。因此選擇濾膜要考慮以下幾個因素:
1.濾膜的材質(zhì)(化學(xué)兼容性):選擇濾膜時,首先要考慮化學(xué)相容性。濾器是否耐酸、堿、有機溶劑等。具體參見濾膜化學(xué)相容性表。
2.濾膜的孔徑:根據(jù)需要過濾的分子或顆粒的大小來確定正確范圍的濾膜孔徑。
3.樣品的特性:
1)親水性樣品:選用親水膜片。對水有親和力,適合過濾水為基質(zhì)的溶液??捎玫臑V膜有:混合纖維素膜,聚醚砜(PEsM),NylonM等。
2)強腐蝕性有機溶劑:一般采用疏水性膜。如PTFEM,聚丙烯(PPM)等材質(zhì)的濾膜
3)蛋白溶液:選擇低蛋白吸附的濾膜,如PVDF濾膜。
4)離子色譜:通常認(rèn)為PEs濾膜比較適合低無機離子的溶液的過濾。
