Abstract

Η εφεύρεση συνίσταται στην ανάπτυξη νέων αντιδιαβρωτικών χρωμάτων που αποτελούνται από ένα πολυμέρη φορέα (όπως λ.χ. το Εποξυδικό κλπ.) και από πιγμέντα η-ημιαγωγικά οξείδια, και σε ενίσχυση των ιδιοτήτων αντιδιαβρωτικών χρωμάτων (όπως λ.χ. η Coal Tar Epoxy, το Χλωριομένο Καουτσούκ κλπ.) Στα νέα αυτά Αντιδιαβρωτικά Χρώματα γίνεται προσθήκη η-ημιαγωγικών οξειδίων καθαρών ή μικτών (ντοπαρισμένων) όπως λ.χ. τα καθαρά ΑΙ2Ο3, Ερυθρά Ιλύ (που περιέχει ΑΙ2Ο3 και Fe2O3), SnO, MgO, SnO2 ή τα μικτά οξείδια AI2O3+MgO ή SnO2 κλπ. και σε αναλογία: ΦΟΡΕΑΣ: ΟΥΣΙΑ (ΠΙΓΜΕΝΟ) = 1έως 50 Για να παραχθούν οι ουσίες αυτές θα πρέπει να ακολουθηθεί ειδική χημική επεξεργασία. Επίσης, η εφεύρεση αυτή αναφέρεται στη δυνατότητα βελτίωσης των αντιδιαβρωτικών ιδιοτήτων ήδη υπαρχόντων αντιδιαβρωτικών χρωμάτων, με τη χρησιμοποίηση η-ημιαγωγικών οξειδίων. Τέλος, η εφεύρεση αυτή αναφέρεται στην ανάπτυξη των αντιδιαβρωτικών ιδιοτήτων των νέων αυτών χρωμάτων με τη χρήση της καθοδικής προστασίας καθώς επίσης και στη δυνατότητα αντικατάστασης μέρους από τήν απαιτούμενη τάση καθοδικής προστασίας με τα η-μιαγωγικά οξείδια (πιγμέντα). ωThe invention consists in the development of new anti-corrosion paints consisting of a polymer carrier (such as Epoxy, etc.) and pigmented n-semiconductor oxides, and in enhancing the properties of anti-corrosion paints (such as Coal Tar Epoxy , Chlorinated Rubber, etc.) In these new Anti-Corrosion Paints, pure or mixed (doped) non-semiconductor oxides are added, such as e.g. the pure Al2O3, Red Mud (containing Al2O3 and Fe2O3), SnO, MgO, SnO2 or the mixed oxides Al2O3+MgO or SnO2 etc. and in proportion: CARRIER: SUBSTANCE (PIGMENT) = 1 to 50 To produce these substances special chemical treatment must be followed. Also, this invention refers to the possibility of improving the anti-corrosion properties of already existing anti-corrosion paints, by using non-semiconductor oxides. Finally, this invention refers to the development of the anti-corrosive properties of these new paints with the use of cathodic protection as well as the possibility of replacing part of the required cathodic protection voltage with semiconductor oxides (pigments). oh
