Patentiert im Deutschen Reiche vom 2. April 1931 abPatented in the German Empire on April 2, 1931

Für die Verhütung der Kesselsteinbildung hat man als mechanisch wirksame Zusätze zum Wasser besonders Petroleumkohlenwasserstoffe und Graphit angewandt. Derartige Mittel haben u, a. den Nachteil, in Wasser unlöslich zu sein und wirken als Fremdkörper.For the prevention of scale formation one has as mechanically effective additives to Water especially petroleum hydrocarbons and graphite are used. Such means have a.o. the disadvantage of being insoluble in water and acting as a foreign body.

Wir haben nun in Wasser lösliche Produkte gefunden, die in hervorragender Weise den Ansatz von Kesselstein verhindern. DieseWe have now found products which are soluble in water and which excellently use the Prevent scale build-up. These

ίο Mittel sind Polyvinylalkohole, wie sie durch Verseifen von Polyvinylester entsprechend dem Patent 450286 darstellbar sind. Diese Polyvinylalkohole bilden mit Wasser kolloidale Lösungen.ίο Means are polyvinyl alcohols as they are made by Saponification of polyvinyl ester according to patent 450286 can be presented. These Polyvinyl alcohols form colloidal solutions with water.

Das neue Verfahren ist natürlich einer ganz allgemeinen Anwendung fähig, eignet'sich aber besonders für solcheFälle ,wo Wasser in abgeschlossenen Räumen erwärmt wird, wie dieses u. a. bei den verschiedenen Formen der Wasserheizung und -kühlung der Fall ist, z. B. bei Boilern, Kochkesseln, Wasserbädern, Heizschränken, Warmwasserzentralheizungen, Kühlung von Verbrennungsmotoren usw.The new method is of course capable of very general application, but is particularly suitable for those cases where water is heated in closed rooms, such as this i.a. at the various forms of water heating and cooling is the case, e.g. B. for boilers, Boiling kettles, water baths, heating cabinets, hot water central heating, cooling of combustion engines etc.

Die Zusatzmengen können je nach den Zweckbestimmungen innerhalb wreiter Grenzen schwanken. Meist werden geringe Mengen Polyvinylalkohol ausreichend wirken. So genügt z. B. zu der Füllung eines Kraftwagenkühlers ein Zusatz von 2 pro Mille Polyvinylalkohol, um während 4 Wochen bei Verwendung von hartem Wasser zum Füllen und Nachspeisen den Ansatz von Kesselstein zu verhindern.The amounts can vary within w r pus limits depending on the purposes. Most of the time, small amounts of polyvinyl alcohol will do the trick. So z. B. to the filling of a motor vehicle radiator an addition of 2 per mille polyvinyl alcohol to prevent scale build-up for 4 weeks when using hard water for filling and topping up.
