Description

Verfahren zur Herstellung von erhärtenden Binden Zement der unter dem Namen Portlandzement allgemein bekannt ist, ist in Mischung mit Sandkies ein vielgebrauchets Nl aterial zur Herstellung von festen Massen.Method of making hardening bandages Cement the under the The name Portland cement is commonly known, is widely used in a mixture with sand gravel Nl aterial for the production of solid masses.

Bei kleineren Reparaturen, wie Ausfüllen von Löchern und Isolierungen, ist es oft umständlich, Zement mit Sand zunächst zu mischen, um ihn dann mit Wasser zu einem Brei zu verrühren, der mit einem Spachtel auf die betreffende Reparaturstelle aufgetragen wird. For minor repairs, such as filling holes and insulation, it is often awkward to mix cement with sand first and then to mix it with water Mix to a pulp, which is applied to the repaired area with a spatula is applied.

Es wurde nun gefunden, daß dieser Arbeitsvorgang sich dadurch wesentlich vereinfachen läßt, daß man eine derartige Mischung, z. B. aus I Teil Portlandzement und 2 Teilen feingemahlenem Sand, durch ein wasserlösliches Klebmittel auf einen Trägerstoff, wie z. B. Mullgewebe, fixiert. Bei der Verwendung wird ein entsprechendes Stück von dieser Zementbinde abgeschnitten, kurze Zeit, etwa 3 Sekunden, in Wasser getaucht, und dann auf die Reparaturstelle aufgebracht. Bei der Erhärtung des Zements wirkt der Trägerstoff gleichzeitig verfestigend. It has now been found that this process is significantly different Can simplify that one such mixture, for. B. from I part Portland cement and 2 parts of finely ground sand, by a water soluble adhesive on one Carrier, such as B. gauze, fixed. When using a corresponding Cut off pieces of this cement bandage for a short time, about 3 seconds, in water dipped, and then applied to the repair site. When the cement hardens the carrier has a strengthening effect at the same time.

Zur Erzielung der Wasserdichtigkeit können bituminöse Stoffe in Verhindung mit Kalkseifen und Tonsei fen der an einem Trägerstoff fixierten Zementmischung zugesetzt werden, um eine Forendichtung l>ei Gebrauch dieser Zementhinden zu erzielen. Auch können zur Herstellung dieser Binden hochwertige Zemente mit schneller Abbinde- und Erhärtungszeit verwendet werden. was z. B. für Tonerdezemente zutrifft. Bituminous substances can be used in order to achieve watertightness with lime soaps and clay soaps, the cement mixture fixed to a carrier can be added to a forum seal when using these cement hindrances achieve. High-quality cements can also be used to produce these bandages faster Setting and hardening time can be used. what z. B. applies to alumina cements.

Ausführungsbeispiel Teil Zement wird mit 2 Teilen feingemahlenem Sand und einer 5%igen wässerigen Methylcelluloselösung zu einem Brei verrührt. der sofort nach seiner Herstellung auf einen Trägerstoff aufgetragen und dessen Wasser nach dem Aufstrich sofort verdunstet wird. Nach Verdunstung des Wassers haftet die Zementmischung durch das Bindemittel fest auf dem Trägerstoff. Exemplary embodiment Part cement is finely ground with 2 parts Sand and a 5% aqueous methyl cellulose solution were stirred to a paste. the immediately after its production applied to a carrier and the water of which evaporates immediately after the spread. After evaporation of the Water, the cement mixture adheres firmly to the carrier material through the binding agent.

IXei Verwendung von schnell abbindenden Spezialzementen kann auch ein Bindemittel vervendet werden, das in organischen, wasserfreien Lösungsmitteln löslich und in Wasser quellbar ist. IXWhen using fast-setting special cements, a binder can be used that is in organic, anhydrous solvents is soluble and swellable in water.

In diesem Fall wird man eine Mischung aus dem Zement und Sand und dem in einem organischen, wasserfreien Lösungsmittel gelösten Klebmittel herstellen, die dann auf den Trägerstoff aufgetragen wird. Derartige Klebmittel sind z.B. Celluloseäther, die in Wasser quellbar und in Methylalkohol löslich sind.In this case you will get a mixture of the cement and sand and make the adhesive dissolved in an organic, anhydrous solvent, which is then applied to the substrate. Such adhesives are e.g. cellulose ethers, which are swellable in water and soluble in methyl alcohol.
