    摘要: High quality, consistent polyurethane froth foams, both filled and unfilled, are prepared by directing polyol, isocyanate, and optionally other polyurethane-forming ingredients to a high pressure mix head prior to introducing the mixture to a froth foaming head. Changes in stoichiometry may be made rapidly without shut-down. An in-line blender incorporated filler into the polyol stream minimizing density differentials normally encountered in the holding tank, maintaining low and reproducible viscosity, and allowing for greater amounts of filler than otherwise possible.

    摘要: The performance of central air conditioning (HVAC) units is significantly enhanced and the cost of operation of the same is greatly decreased by the elements of the present invention with the water spraying system which may include an electrically actuated solenoid valve to initiate the flow of water to the water spray nozzles in coordination with the beginning of the air conditioner compressor cycle. A drain valve unit may allow water to drain from the piping and water spray nozzles when the central air conditioning (HVAC) unit is not operating.

    摘要: Flexible, slabstock polyurethane foam compositions useful for a rapid-cool process are disclosed. The foams are produced in the presence of a tetravalent tin catalyst, preferably at a relatively low isocyanate index, and preferably with a polyol that contains a non-volatile inhibitor. The foams of the invention eliminate or greatly reduce the amount of visible smoke produced in a rapid-cool process.
