Description

Verfahren zur Behandlung von Faserstoffen, insbesondere Halmgewächsen, vor ihrer Verarbeitung zu Bau- und Isoliermaterial Zusatz zum Patent 937 635 Das Patent 937 635 betrifft die Behandlung bzw. Imprägnierung von Faserstoffen mit einem basisch gemachten Aluminiumsulfat. Weitere Versuche haben ergeben, daB man auch das handelsübliche, in wäßriger Lösung sauer reagierende Aluminiumsulfat benutzen kann, wenn es in Verbindung mit Calciumchlorid (Ca C19) verarbeitet wird. Man verwendet die wasserfreien Salze, löst sie gesondert in Wasser, bringt diese Lösungen jeweils kurz vor der Verarbeitung zusammen. Eine sofort einsetzende Gipsbildung wird durch Zumischung von Bitumenemulsion in gewünschter Grenze gehalten. Zulässig ist auch die Beigabe geeigneter Kunstharzemulsion. Damit die mit der sauren Reaktionslösung zusammen verwendeten Bifumen- oder Kunstharzemulsionen beständig sind, dürfen nur solche Emulsionen. benutzt werden, die keine verseifbaren Emulgatoren besitzen.Process for the treatment of fibrous materials, in particular stalk plants, Before processing them into building and insulating material, addendum to patent 937 635 Das U.S. Patent 937,635 relates to the treatment or impregnation of fibrous materials with a basified aluminum sulfate. Further experiments have shown that one too use the commercially available aluminum sulphate, which reacts acidic in an aqueous solution can if it is processed in connection with calcium chloride (Ca C19). One uses the anhydrous salts, dissolving them separately in water, brings these solutions in each case shortly before processing together. An immediately onset of plaster of paris is caused by Mixing bitumen emulsion kept within the desired limit. Is also permissible the addition of a suitable synthetic resin emulsion. So that with the acidic reaction solution Bifumen or synthetic resin emulsions used together may only be resistant such emulsions. which do not have saponifiable emulsifiers.

Der bei der Reaktion ausgeschiedene Gips dringt mit der Reaktionslösung in die Poren der Faser- Stoffe ein, setzt sich dort ab und verkrustet. Versuche haben gezeigt, da ß diese geringen Gipsmengen, die durch das beigemischte Bitumen verklebt werden, bei der späteren Verarbeitung der so präparierten Faserstoffe keinen schädlichen Einfluß auf den zur Bindung benutzten Zement ausüben. Es erübrigt deshalb ein zusätzliches Verfahren zur Unschädlichmachung von Gips. Anwendungsbeispiel 5 kg A12 (S 04) 3 und 7 kg Ca C12 werden in j e 40 kg Wasser gelöst. Vor Gebrauch werden beide Lösungen zusammengebracht und etwa 2o Gewichtsprozent einer Bitumenemulsion beigemischt, die ohne verseifbare Emulgatoren erzeugt wurde. Hiermit können je nach Art der Faserstoffe 5o bis zoo kg Fasern imprägniert werden.The gypsum separated out during the reaction penetrates with the reaction solution into the pores of the fiber Substances set in, settle there and become encrusted. Tests have shown that these small amounts of gypsum, which are mixed in by the Bitumen are glued during the later processing of the fiber materials prepared in this way exert no harmful influence on the cement used for bonding. There is no need therefore an additional process to render plaster of paris harmless. Application example 5 kg of A12 (S 04) 3 and 7 kg of Ca C12 are dissolved in 40 kg of water. Before use both solutions are brought together and about 20 percent by weight of a bitumen emulsion added, which was produced without saponifiable emulsifiers. This can be used depending on Type of fibrous material 5o to zoo kg of fibers are impregnated.
