Heteregene IonenaustauscherfolieHeterogeneous ion exchange film
Die Erfindung betrifft heterogene Ionenaustauscherfolien mit hoher Quellfähigkeit mit Polysinylohlorid als Bindemittel.The invention relates to heterogeneous ion exchange films with high Swellability with polysinylochloride as a binding agent.
Heterogens Ionenaustauscherfolien sind bekannt. Sie bestehen aus Ionenaustauscherharzen in Pulverform und geeigneten plastisehen Bindemitteln, in der Regel thermoplastisohen Polymeren (Polystyrol, Polyvinylchlorid, Polymethylmethacrylat, Polyäthylen u. a.). Die Verarbeitung der Ausgangsmischung erfolgt meist thermoplastisoh, kann aber auoh durch Pressen bzw. Gießen von Eilmen aus einer Lösung erfolgen (B. N. Laskorin u. a. "Ionenaustauscher-@embranen und ihre Anwendung", Akademie-Verlag, Berlin 1966). Bei Normaltemperatur relativ spröde Thermoplaste, wie Polystyrel oder Polyvinylchlorid, eignen sich dabei höchstens für schwach quellende Ionenaustauscher. Für nermal bzw.Heterogeneous ion exchange films are known. They consist of ion exchange resins in powder form and suitable plastic binders, usually thermoplastic binders Polymers (polystyrene, polyvinyl chloride, polymethyl methacrylate, polyethylene, etc.). The processing of the starting mixture is mostly thermoplastic, but can also be used by pressing or pouring Eilmen from a solution (B. N. Laskorin u. a. "Ion exchange @ embraces and their application", Akademie-Verlag, Berlin 1966). Thermoplastics that are relatively brittle at normal temperature, such as polystyrene or polyvinyl chloride, are at most suitable for weakly swelling ion exchangers. For nermal resp.
stark quellende Ionenaustauscher werden elastische Bindemittel aus synthetischem oder natürlichem Kautschuk oder solchen Polymeren, die bei Normaltemperatur über ausgezeichnete Flexibilität verfügen (z. B. Polyäthylen, Polyisobutylen), verwendet (DL -WP 38.391). Nachteilig wirken sich dabei jedoch die relativ stark ausgeprägten hydrophoben Eigenschaften dieser weitgehend apolaren Polymeren aus, die die Transportvorgänge in der Ionenaustausohermembran behindern. Es wurde deshalb wiederholt versucht, polare Polymere, wie Polyvinylchlorid, als Bindemittel für lonenaustausoher zu verwenden, wobei die Sprödigkeit des Polyvinylohlorid z. B. dadurch Abmisohung mit anderen Polymeren bzw. Copolymerisatiow. nur teilweise überwunden werden konnte.strongly swelling ion exchangers are made from elastic binders synthetic or natural rubber or such polymers that are at normal temperature have excellent flexibility (e.g. polyethylene, polyisobutylene) are used (DL-WP 38.391). However, the relatively strong ones have a disadvantage here hydrophobic properties of these largely non-polar polymers make up the transport processes in the ion exchange thermal membrane. It has therefore repeatedly been attempted to use polar polymers, such as polyvinyl chloride, as binders for ion exchangers, wherein the brittleness of the polyvinyl chloride z. B. thereby disagreement with others Polymers or copolymers. could only be partially overcome.
Auch der Vorschlag, dem PVC die üblichen Weiohmaahermengen beizufügen, führte nicht zu einem befriedigenden Ergebnis, da wegen der geringen mechanisohen Festigkeit solcher Mischungen Gewebeverstärkungen erferderlich sind bzw. bei einer nachträgliohen Extraktion des Weichmachers als zusätzlichem lrbeitsaufwand die wirkung des Weichmachers wieder verloren geht (Indien Patent-Nr. 109.715; Kosaka, Sato, Tadsima - J.Chem.Also the suggestion to add the usual quantities of Weiohmaher to the PVC, did not lead to a satisfactory result because of the poor mechanical properties Strength of such mixtures fabric reinforcements are necessary or at a Subsequent extraction of the plasticizer as additional labor the effect of the plasticizer is lost again (India Patent No. 109.715; Kosaka, Sato, Tadsima - J.

Der Erfindung liegt die Aufgabe zugrunde, heterogene Ionenaustauscherfolien auf Polyvinylchloridbasis zu schaffen, die eine optimale Quellfähigkeit besitzen, eine gegenüber bekannten heterogenen Ionenaustauscherfolien verbesserte Ausnutzung der Ionenaustauschkapazität ermöglichen und über eine ausreichende mechanische Festigkeit verfügen.The invention is based on the object of providing heterogeneous ion exchange films to create on a polyvinyl chloride basis, which have an optimal swelling capacity, an improved utilization compared to known heterogeneous ion exchange films the ion exchange capacity and have sufficient mechanical strength feature.
Die erfindungsgemäßen heterogenen Ionenaustauscherfolien bestehen aus Mischungen ven 30...100 Gewichtsteilen Ionenaustauscherharz und 30...40 Gewichtsteilen pulverförmigem Polyvinylchlorid sowie 2 - 15 % Weichmacher.The heterogeneous ion exchange films according to the invention exist from mixtures of 30 ... 100 parts by weight of ion exchange resin and 30 ... 40 parts by weight powdered polyvinyl chloride and 2-15% plasticizers.
Als Weichmacher eignen sioh alle mit'Polyvinylchlorid verträglichen Weichmacher bzw. Weichmachergemische, wobei solche Ester-Weichmacher, die die Wasseraufnahme des Polyvinylchlorid@ günstig beeinflussen Cz. 3. Adipinate und Phthalate mit bis zu 8 C-tomen im Alkoholrest), besonders gttnstig wirken.Suitable plasticizers are all those compatible with polyvinyl chloride Plasticizers or plasticizer mixtures, with those ester plasticizers that absorb water of polyvinyl chloride @ favorably influence Cz. 3. Adipinates and phthalates with up to 8 carbon atoms in the alcohol residue), have a particularly beneficial effect.
Die besten Ergebnisse bezüglich der geferderten Eigenschaften besitzen Folien, in denen die Korngröße des eingesetzten Ionenaustauscherharzes < 80 µm beträgt.Have the best results in terms of the cushioned properties Films in which the grain size of the ion exchange resin used is <80 µm amounts to.
Die Quellfähigkeit der Peie kann, erhöhe und die Ionenaustausohkapazität vollständiger ausgenutzt werden, indem der Mischung wasserlösliche anorganische Salze (z. B. @aHCO3, NaCl, CaCO3, Na2SO4) in Pulverform in Mengen von 1...10 Gew.-% zugesetzt und diese Salze nach der Herstellung der Membran mit Wasser wieder herausgelöst werden. Das Herauslösen dauert nur wenige Stunden und kann mit der sowiese erforderlichen Quellung der Folie verbunden werden. In der rolle bilden sich dabei kleinste Hohlräume bzw. Kanäle, die die Zugänglichkeit zum Ionenaustauscher erhöhen. Das zeigen auch die Zahlen für die Quellfähigkeit heterogener Ionenaustauscherfolien mit unterschiedlichen Weichmaoher- und Salzzusätzen, die in Tabelle 1 angeführt sind.The swelling capacity of the peie can increase and the ion exchange capacity Can be more fully exploited by adding the water-soluble inorganic mixture Salts (e.g. @ aHCO3, NaCl, CaCO3, Na2SO4) in powder form in quantities of 1 ... 10% by weight added and these salts dissolved out again with water after the production of the membrane will. Removal takes only a few hours and can be done with the necessary Swelling of the film are connected. Smallest cavities are formed in the roll or channels that increase the accessibility to the ion exchanger. Show that too the numbers for the swellability of heterogeneous ion exchange films with different Softening ingredients and salt additives, which are listed in Table 1.
