Description
- 1. Die Reaktionskunststoffkomponenten werden gemeinsam mit den vorgesehenen Additiven sowie den Treibmitteln bei hoher Geschwin digkeit kontinuierlich der Rezeptur entsprechend vermischt und unverzüglich in eine wesentlich kältere flüssige Phase eingebracht, die z. B. ein flüssiges Stickstoffbad sein kann. Hierdurch wird aus den Flüssigkunststoffen rieselfähiges Granulat oder Pulver.
- 2. Das gekühlte, angemischte Reaktionskunststoffpulver ist in dieser Form lagerfähig und unter Einhaltung bestimmter Tempe raturbedingungen transportfähig. Somit kann "trockene" Granulat- oder Pulvermasse an den Ort der weiteren Verarbeitung verbracht werden, z. B. durch rollbare gekühlte Kleincontainer.
- 3. Am Ort der weiteren Verarbeitung, z. B. einem Schäumwerkzeug, wird eine bestimmte Menge Granulat oder Pulver dem Container ent nommen und in sehr einfacher Weise ohne Druck und Verklebung, lösungsmittelfrei in das Werkzeug eingefüllt.
- 4. Die eingebrachte Menge Reaktionskunststoffgranulat nimmt die Temperatur des gegebenenfalls auch beheizten Werkzeugs an, wird flüssig und reagiert dann entsprechend seiner spezifischen Re aktivität schnell und stark exotherm, wodurch auch höhersieden de Treibmittel zur Verdampfung gebracht und der gewünschte Schäum prozeß ermöglicht wird.
