Description
Verfahren zur Herstellung oberflächenaktiver Wundkompressen Die Erfindung bezieht sich in weiterer Ausbildung des Gegenstandes des Patents 710 790 auf ein Verfahren zur Herstellung oberflächenaktiver Zellstoffwatte. Vorzugsweise wird diese Watte als Grundstoff bei der Fertigung von Wundkompressen und Monatsbinden eingesetzt. Die vorteilhaften Wirkungen eines Zusatzes von Aktivkohle bzw.Process for the production of surface-active wound compresses The invention relates to a further development of the subject matter of patent 710,790 Process for the production of surface-active cellulose wadding. Preferably this is Wadding is used as a basic material in the manufacture of wound compresses and sanitary napkins. The beneficial effects of adding activated carbon or
Kieselgel als Adsorptionsmittel sind bekannt. Nach Patent 710 790 wird Aktivkohle oder Kieselgel im Verlauf des Herstellungsverfahrens der Zellstoffwatte zugesetzt.Silica gel as an adsorbent are known. According to patent 710,790 becomes activated carbon or silica gel in the course of the cellulose wadding manufacturing process added.
Nach der Erfindung werden an sich bekannte technische Mittel mechanischer, chemischer, elektrochemischer oder elektrischer Natur, z. B. unter Benutzung elektrischer Ladungen, angewendet, um in konzentrierter Form die Aktivkohle bzw. Kieselgel in dauerhafter Weise in dem Faserbrei niederzuschlagen. Die Mischung von Papieren mit Füllstoffen mit Ruß und aktiver Kohle sowie die Verwendung chemischer Mittler zur Anlagerung dieser Füllstoffe sind in der Papierfabrikation bekannt. According to the invention known technical means of mechanical, chemical, electrochemical or electrical nature, e.g. B. using electrical Charges, applied to the activated carbon or silica gel in concentrated form permanent way to precipitate in the pulp. The mixture of papers with Fillers with carbon black and active carbon as well as the use of chemical mediators for The accumulation of these fillers is known in paper manufacture.
Das Neuartige liegt darin, Aktivkohle oder Kieselgel mit hoher Oberflächenaktivität durch geeignete Auswahl physikalischer oder chemischer Verfahren auf den Fasern des Zellstoffes niederzuschlagen. An physikalischen oder mechanischen Arbeitsweisen seien Rieselung, Schlämmung, trockene Aufstäubung, Spritzen oder Sprühung einer Suspension genannt. Dieses Versprühen oder Verspritzen kann unter der Anwendung von Preßluft, von Sog- oder Druck- oder auch jeden anderen üblichen mechanischen Vorrichtungen erfolgen. The novelty is activated carbon or silica gel with high surface activity through a suitable selection of physical or chemical processes on the fibers knock down the pulp. In physical or mechanical working methods be trickling, slurrying, dry dusting, splashing or spraying one Called suspension. This spraying or splashing can be done using by compressed air, by suction or pressure or any other usual mechanical Devices take place.
Eine weitere Möglichkeit besteht darin, nach bekannten chemischen Reaktionen Kieselgel in der Faserbreimasse zu erzeugen. Dieses Gel wird in wirkungsvoller Weise auf der Faser niedergeschlagen. Der Zeitpunkt der Einverleibung von Aktiv- kohle oder Kieselgel kann während des feuchten Zustandes des bereits gebildeten Zellstoffvlieses, also auf der Siebbahn, erfolgen. Es können aber auch spätere Herstellungsabschnitte der erreichten Trocknung auf der Trockentrommel ausgewählt werden.Another option is to look for known chemical Reactions to produce silica gel in the pulp mass. This gel will be more effective Way down on the fiber. The time of incorporation of active money or silica gel can be used during the moist state of the cellulose fleece that has already formed, that is, on the sieve conveyor. However, later manufacturing stages can also be used the drying achieved on the drying drum can be selected.
Dieses so mit Aktivkohle oder Kieselgel verbundene Zellstoffvlies kann zweckmäßig bei der Herstellung von Wundkompressen oder Monatsbinden Anwendung finden, weil es hohe Adsorptionseigenschaften besitzt. This cellulose fleece connected in this way with activated carbon or silica gel Can be used in the manufacture of wound compresses or sanitary napkins because it has high adsorption properties.
