    摘要： A process for rapidly cooling porous foam material to prevent oxidation or autoignition of said foam. The process includes a first cooling step wherein cooled ambient air is drawn through the foam block thereby cooling, dehumidifying and removing fumes from said block before being vented, a second cooling step wherein cooled ambient air is drawn through the block for further cooling thereof, with sublimates in the block being condensed and redeposited within the block, and a third cooling step wherein ambient air is drawn through the material so as to remove remaining fumes, heat and moisture therefrom. The process of the present invention advantageously utilizes a foam formulation which includes an increased percentage of water for providing adequate foaming of the material while minimizing or obviating the need for including toxic auxiliary blowing agents in the formulation. In addition, the formulation may also have a lower TDI index as compared to formulations utilized in conventional cooling methods because TDI is condensed and recycled back into the foam. An apparatus especially configured and adapted for practicing the process of the present invention is also disclosed.
