Abstract

For fremstilling av fluorklorhydrokarbon (FCKW)-frie skumplaster, spesielt polyuretan-skumplaster, anvendes rent nitrogen som drivmiddel, som oppnås ved simultan, binær reaksjon av ionene NH4+ og N0£ fra to oppløs- ninger, som danner NH4+- og N02~-ioner, av ammoniumsal- ter og alkalinitrltter, som ammoniumklorid- eller ammoniumsulfatoppløsning og natriumnltritt- eller kaliumnltrlttoppløsning.
