Description
Verfahren zur Herstellung von Kalkanstrichmassen Zusatz zum Zusatzpatent 658 716 Die Erfindung betrifft eine Weiterausbildung des Verfahrens zur Herstellung von Kalkanstrichmassen nach Zusatzpatent 658716, welches dass Vermischen des noch heißen bzw. warmen Kalkbreies mit der Formaldehydlösung in an sich bekannten, zu verschließenden, gegebenenfalls mit Rührwerk ausgestatteten Behältern, zweckmäßig unter Rühren bis zur Abkühlung betrifft.Process for the production of lime paints Addendum to additional patent 658 716 The invention relates to a further development of the process for the production of lime paints according to additional patent 658716, which involves mixing the still hot or warm lime slurry with the formaldehyde solution in known, to be sealed, possibly equipped with a stirrer Containers, advantageously concerns with stirring until cooling.
Der Erfindung gemäß wird die Löschflüssigkeit dabei nur in zur Erzielung eines praktisch wasserfreien Erzeugnisses eben ausreichenden Mengen verwendet. Hierdurch wird nach Beendigung des Löschvorgangs an Stelle eines formaldehydhaltigen Kalkbreies ein praktisch wasserfreies Trockenerzeugniserhalten, welches meistens schon genügend feinpulverige Beschaffenheit aufweist, so daß keinerlei Nachtrocknen der Masse mehr erforderlich ist.According to the invention, the extinguishing liquid is only used in order to achieve this of a practically anhydrous product, sufficient quantities are used. Through this is used in place of formaldehyde-containing lime slurry after the extinguishing process is complete get a practically anhydrous dry product, which is usually enough has a fine powdery consistency, so that no further drying of the mass is required.
Beispielsweise werden dabei auf je i oo kg gebrannten Kalk etwa 3o bis 40 kg wäßrige Löschflüssigkeit verwendet.For example, about 30 per 100 kg of quicklime are used up to 40 kg of aqueous extinguishing liquid used.
Die nach diesem Verfahren hergestellten Anstrichmassen in praktisch trockener Form werden zweckmäßig erst an der Verwendungsstelle mit erforderlichen Mengen Wasser streichfertig angemacht und sind durch den Fortfall des Wasserballastes besser lager-und billiger versandfähig.The paint compositions produced by this process in practically dry form are expedient only at the point of use with required Amounts of water are prepared ready for use and are through the Elimination of the water ballast better to store and cheaper to ship.
Die sogenannte Trockenlöschung von Kalk ist zwar an sich bekannt; die Anwendung des Trockenlöschverfahrens aber auf die Kalkanstriclunassen gemäß Zusatzpatent 658716 stellt eine wesentliche Vervollkommnung dieser Massen dar, ohne daß deren vorteilhaften Eigenschaften beeinträchtigt werden.The so-called dry slaking of lime is known per se; However, the application of the dry slaking process to the Kalkanstriclunassen according to additional patent 658716 represents an essential improvement of these masses without their advantageous properties being impaired.
