Open-loop apparatus for producing a controlled blend of polyol and blowing agent for use in the manufacture of polyurethane foam

摘要: A novel apparatus has been discovered which is of value in the production polyurethane foam. This invention relates to a one-pass, on-demand for producing controlled, homogeneous blend polyol-blowing agent mixture used manufacture foam using either low-boiling point or high-boiling blowing agent. An provided control amount each material mixture, ensure blending two materials after mixing, pressure means maintain agents their liquid state (where necessary), and monitoring allows rapid verification operating status entire system.
