Abstract

Apparatur for blanding av reaktive poly- uretan-bestanddeler, et flytende esemid- del og et gassformig nukleeringsmiddel under trykkregulerte betingelser, omfat- tende et hullegerae med et deksel, en yttervegg og en bunnvegg med en sentral utløpsåpning, og en rotordel som er roterbart anbragt i hullegemet. De mot- stående overflater på rotordelen og bunnveggen har flere aksialt utstikkende pinner som er i inngrep med hverandre. Overflatene definerer et ringformet blandekammer som strekker seg radialt fra ytterveggen mot den sentrale utløpsåpning. Det beskrives også en fremgangsmåte for fremstilling av et forekspandert polyuretanskum, omfattende blanding av be- i standdelene, esemidlet og nukleeringsgassen i blandingskammeret. Den resul- terende blanding føres langs en blandebane som strekker seg radialt mellom motstående overflater på rotordelen og bunnveggen, og blandingen utsettes for gjentatte og intense mekaniske rørevirk- ninger og virvelvirkninger samtidig som den bringes til å strømme i blandebanen radialt mot sentrifugalkreftene dannet av rotordelen, og til den sentrale utløpsåpning.
