METHOD OF INTRODUCING REACTION MIXTURES FOR SINGLE-COMPONENT FOAMS INTO PRESSURE CONTAINERS

摘要

A METHOD OF INTRODUCING REACTION MIXTURES FOR SINGLE-COMPONENT FOAMS INTO PRESSURE CONTAINERS The invention relates to a method of introducing reaction mixtures for single-component foams into pressure containers. The reaction mixture comprises at least two reaction components and a blowing agent and is formed in an injection mixing head. The reaction mixture is then introduced into an evacuated pressure bottle provided with a valve. Additional pure blowing agent is added via the injection mixhead subsequent to the introduction of the reaction mixture into the pressure container.
