摘要： An apparatus for the continuous production of foamed plastics is described. The apparatus includes i) a continuous conveyor belt, and ii) a transversely reciprocating applicator device located over the belt for applying a foam-forming reaction mixture. The applicator device includes a mix head and a detachably mounted magazine plate having several openings thereon. Each opening has a casting tube connected thereto. Each casting tube has discharge holes on its underside. The plate is adjustable in such a way that the casting tubes can be connected successively to the outlet of the mixhead.

摘要： The present invention is directed to a novel process and apparatus for charging a liquid reactant with a gas. In the process, the liquid reactant which is as yet uncharged with gas is introduced into the gassing tank at a point just below the substantially constant liquid level of the reactant. When the reactant has been charged with gas, it is removed at a point below the region where gassing takes place. A three-layered arrangement is thereby established and maintained in the gassing tank so that the layer of gas is separated from the layer of gas charged component by the layer of uncharged component. The gas charged component is thus maintained at a density corresponding to the desired gas content, taking into account any significant starting conditions, such as the original density, the temperature and the pressure. If necessary, this density is maintained by suitably varying the stirrer speed.

摘要： This invention relates to a process for the preparation of polyurethane foams by the reaction of a foamable reaction mixture. A liquid blowing agent is added to either the isocyanate or the polyol prior to mixing of the components. An inert gas is dispersed in the component which contains the blowing agent and the gas charged component is immediately and continuously mixed with the other component, at the same time keeping it at least under the pressure required for charging it with gas until mixing has been completed, and leaving the resulting reaction mixture to foam up. The key to the present invention is in the small amount of gas charging.

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.
