Abstract

Ασύμμετρη μεμβράνη που περιλαμβάνει σωληνοειδές πολυμερές φιλμ σε συνδυασμό με σωληνοειδή πλέξη, πάνω στην οποία στηρίζεται το φιλμ, προϋποθέτει ότι η πλέξη είναι μακροπορώδης και εύκαμπτη, ωστόσο αρκούντως ανθεκτική σε συνεχή κάμψη, έκταση και τριβή κατά τη διάρκεια της χρήσεως για μικροδιήθηση (microfiltration, MF) ή υπερδιήθηση (ultrafiltration, UF) . Παρέχονται οι προδιαγραφές για μια πλέξη μεμβράνης μακράς διάρκειας ζωής. Η μεμβράνη σχηματίζεται υποστηρίζοντας ένα πολυμερές φιλμ, στο οποίο έχουν διασπαρεί σωματίδια ασβεστοποιημένης α-αλουμίνας, πάνω στην καθορισμένη σωληνοειδή πλέξη.
