        復(fù)合膜制備方法有哪幾類?

        2023-05-16

        復(fù)合膜的材料包括任何可能的材料結(jié)合,如在金屬氧化物上覆以陶瓷膜或是在聚砜微孔膜上覆以芳香聚酰胺薄膜,其平板膜或卷式膜都要用非織造物增強(qiáng)以支撐微孔膜的耐壓性,而中空纖維膜則不需要。由天成復(fù)合膜廠家介紹一下復(fù)合膜制備方法有哪幾類?

        復(fù)合膜制備方法分為四類:

        (1)復(fù)合膜-層壓法,首先制備很薄的致密均質(zhì)膜,而后層壓于微孔支撐膜上;

        (2)復(fù)合膜-浸涂法,把聚合物溶液浸涂于微孔膜上,然后干燥而成,也可以把活性單體或預(yù)聚物溶液浸涂于微孔膜上,用熱或輻射固化;

        (3)復(fù)合膜-等離子體氣相沉積法,用等離子輝光使微孔支撐膜的表面產(chǎn)生致密的均質(zhì)膜;

        (4)復(fù)合膜-界面聚合法,在微孔支撐膜表面上,用活性單體進(jìn)行界面聚合。
