Um zwei oder mehrkomponentige Abformmaterialien zu mischen, werden diese normalerweise durch Kneten von Hand, mittels sogenannten Automixmaschinen oder mittels Mischpistolen angemischt.Around to mix two or more component impression materials this usually by kneading by hand, by means of so-called Automixmaschinen or mixed by means of mixing guns.
Dabei werden speziell hochviskose Materialien durch Kneten von Hand miteinander homogenisiert. Hierfür werden zum Beispiel Stränge definierter Menge durch Druck- und Scherbelastung vermengt. Mittel- bis hochviskose Materialien werden mit sogenannten Automixmaschinen unter Zuhilfenahme eines dynamischen Mischers, bei dem das Innenteil des Mischers während des Mischvorganges rotiert und den Vortrieb und die Vermengung der Komponenten unterstützt, homogenisiert.there are specially high-viscosity materials by kneading by hand with each other homogenized. For this example, strands defined amount mixed by pressure and shear stress. Medium- to high-viscosity materials are using so-called automix machines with the aid of a dynamic mixer, in which the inner part of the Mixer during the mixing process and the propulsion and the mixing of the components supported, homogenized.
Im Dentalbereich bevorraten die Kartuschen- und Schlauchbeutelsysteme hierfür zwischen 300 und 400 ml Rohmaterial. Die Mischgeräte sind in der Regel stationär und können nicht auf einfache Weise von einem Arbeitsplatz zu einem anderen transportiert werden.in the Dental care stores the cartridge and tubular bag systems for this, between 300 and 400 ml of raw material. The mixers are usually stationary and can not stand up easy way of moving from one workstation to another become.
Es ist bekannt, niedrigviskose Materialien mittels Mischpistolen, bestehend aus einem Handgriff, einem mechanischen oder elektrischen Antrieb und einem statischen Mischer, homogen zu vermengen. Das Innenteil des statischen Mischers bleibt während des Mischvorganges starr. Die zugehörigen Kartuschen haben im Dentalbereich in der Regel einen Materialvorrat von < 150 ml. Diese Mischsysteme erlauben, dass sie, bedingt durch ihr geringes Gewicht und ihre Abmessung, einfach an verschiedenen Orten angewendet werden können.It is known, low-viscosity materials by means of mixing guns, consisting from a handle, a mechanical or electric drive and a static mixer to mix homogeneously. The inner part of the static mixer remains rigid during the mixing process. The associated cartridges have in the dental field in the Usually a material stock of <150 ml. These mixing systems allow them, due to their low weight and their dimension, easy to be applied in different places can.
