Abstract
Description
Um ein Entmischen der unterschiedlichen Partikel in der Waschmittelformulierung während Transport und Lagerung zu vermeiden, sollte der Partikeldurchmesser zwischen 0,2 mm und 2 mm, bevorzugt zwischen 0,5 mm und 0,8 mm, die Teilchenlänge im Bereich von 0,5 mm bis 3,5 mm, idealerweise zwischen 0,9 mm und 2,5 mm liegen.
Alle bisher beschriebenen Verfahren zur Herstellung von Extrudaten liefern entweder Formkörper mit einer relativ breiten Partikelgrößenverteilung und/oder einem vergleichsweise hohen Staubanteil. Die Partikel weisen an den Schnittstellen scharfe Ecken und Kanten auf, die einen hohen Abrieb mit Staubbildung und ein ungünstiges Fließverhalten verursachen. Erfolgt die Herstellung der Extrudate unter hohen Verdichtungskräften wird das Löseverhalten der Partikel wesentlich beeinträchtigt.
Die vorzugsweise eingesetzten Polyethylenglykole können eine lineare oder verzweigte Struktur aufweisen, wobei insbesondere lineare Polyethylenglykole bevorzugt sind. Zu den insbesondere bevorzugten Polyethylenglykolen gehören solche mit relativen Molekülmassen zwischen 2000 und 12000, vorteilhafterweise um 4000, wobei Polyethylenglykole mit relativen Molekülmassen unterhalb 3500 und oberhalb 5000 insbesondere in Kombination mit Polyethylenglykolen mit einer relativen Molekülmasse um 4000 eingesetzt werden können und derartige Kombinationen vorteilhafterweise zu mehr als 50 Gew.-%, bezogen auf die gesamte Menge der Polyethylenglykole, Polyethylenglykole mit einer relativen Molekülmasse zwischen 3500 und 5000 aufweisen.
Zu den modifizierten Polyethylenglykolen gehören auch ein- oder mehrseitig endgruppenverschlossene Polyethylenglykole, wobei die Endgruppen vorzugsweise C1-C12-Alkylketten, bevorzugt C1-C6, die linear oder verzweigt sein können, darstellen. Einseitig endgruppenverschlossene Polyethylenglykolderivate können auch der Formel Cx(EO)y(PO)z entsprechen, wobei Cx eine Alkylkette mit einer C-Kettenlänge von 1 bis 20, y 50 bis 500 und z 0 bis 20 sein können.
Ebenso geeignet sind niedermolekulare Polyvinylpyrrolidone und Derivate von diesen mit relativen Molekülmassen bis maximal 30 000. Bevorzugt sind hierbei relative Molekülmassenbereiche zwischen 3000 und 30 000. Polyvinylalkohole werden vorzugsweise in Kombination mit Polyethylenglykolen eingesetzt.
Größe und Form der Partikel können im Rondierverfahren durch mehrere Parameter beeinflusst und herbeigeführt werden. Der Formungsprozess wird bestimmt durch die Füllmenge, die Temperatur der Mischung, die Verweilzeit der Mischung im Rondierer, durch die Drehgeschwindigkeit der Rondierscheibe, sowie durch die plastische Verformbarkeit der Mischung.
Mit abnehmender Füllmenge im Rondierer werden kürzere Zylindergranulate und eine engere Verteilung der Partikelgrößen erhalten. Mit abnehmender Temperatur und damit geringer werdender Plastizität werden längere Granulate erhalten, bei weiterer Abkühlung nimmt der Staubanteil stark zu.
Die Verweilzeit der Mischung im Rondierer hängt neben der Plastizität von der Füllmenge ab und beträgt bevorzugt 10 sec. bis 120 sec., besonders bevorzugt 20 sec. bis 60 sec., die Umfangsgeschwindigkeit 10 m/sec. bis 30 m/sec., bevorzugt 12 m/sec. bis 20 m/sec.
Nach dem Formungsprozess werden die zylindrisch geformten und abgerundeten Partikel in einem nachgeschalteten Apparat, vorzugsweise in einem Fließbettkühler im kalten Luft- oder Gasstrom auf Temperaturen unterhalb 40°C abgekühlt, um ein Verkleben der Granulate zu vermeiden.
Das Schüttgewicht liegt im Bereich 300 g/l bis 2000 g/l, bevorzugt im Bereich 400 g/l bis 1500 g/l und besonders bevorzugt im Bereich von 500 - 800 g/l.
Die erhaltenen Granulate zeichnen sich durch eine sehr gute Abriebfestigkeit und Lagerstabilität in pulverförmigen Wasch-, Reinigungs- und Desinfektionsmittelformulierungen aus. Sie sind ideal zum Einsatz in Vollwaschmitteln, Fleckensalzen, Maschinengeschirrspülmitteln, pulverförmigen Allzweckreinigern und Gebissreinigem.
