摘要： The invention relates to a method for the production of polyurethane block foam, wherein a polyurethane reactive mixture containing carbon dioxide is suddenly relieved from a pressure above the pressure breaking the equilibrium of the carbon dioxide to a normal pressure, wherein the liquid polyurethane reactive mixture is foamed by releasing dissolved carbon dioxide. The foamed mixture is placed on a substrate and then hardened into block foam, wherein the carbon dioxide or at least one of the components polyol and isocyanate is initially dissolved in the reactive mixture at a pressure that is substantially above the pressure breaking the equilibrium, the pressure is subsequently lowered to a pressure close to the pressure breaking the equilibrium, wherein the pressure falls below the pressure breaking the equilibrium by releasing small amounts of carbon dioxide and forming a microdispersion of bubbles, the components are optionally mixed and a sudden pressure drop to normal pressure occurs before the carbon dioxide released is completely dissolved.

摘要： The instant invention relates to a method and apparatus for measuring the proportion of undissolved gas in a liquid component for the production of foam materials, particularly those based on polyurethanes. The method is based on the equation of state of ideal gases (Boyle-Mariot Law: p.multidot.v = constant) at constant temperatures. The gaseous portion of a liquid component charged with gas increases its volume under expansion according to the above equation. The gas expansion also increases the liquid volume. The differences in the volumes, of the liquid at two differing pressures is therefore a measurement of the quantity of gas present in the liquid. The apparatus consists of a closed graduated measurement vessel being connected to a variable pressure means capable of producing at least two different defined pressures.
摘要翻译：本发明涉及用于测量用于生产泡沫材料的液体组分中未溶解气体的比例，特别是基于聚氨酯的泡沫材料的比例的方法和装置。该方法基于在恒定温度下理想气体的状态方程（Boyle-Mariot法：pxv =常数）。充满气体的液体成分的气体部分根据上述等式增加其膨胀时的体积。气体膨胀也增加了液体体积。因此，在两个不同压力下的液体体积的差异是测量液体中存在的气体的量。该装置由闭合的刻度测量容器连接到能够产生至少两个不同的限定压力的可变压力装置。

摘要： The present invention provides a mixing head having vertical lift slides in which the injection pressures can be altered. Each lift slide is provided with a number of injection openings of different diameters arranged in one plane perpendicular to the axis of the slide. The injection pressure is altered by rotating the lift slide to bring a different injection opening into registry with a mixing chamber. The head of each lift slide is provided with a head having change-over detents which mesh with a carrying yoke to facilitate changing injection openings. The lift slides may also be provided with return openings of such diameter that the pressure in the system remains the same whether the slides are in a mixing position or a return position.
