Abstract:
A method of cooling hot-pressed planar material having an initial temperature of at least 110.degree. C., comprising:a first cooling step of cooling at least one surface of said planar material from said initial temperature to an intermediate surface temperature of about 100.degree. C. during a first time period using water as a cooling medium, wherein a vapor mixture including saturated water steam and a volatile binder component volatilized from said planar material is evolved during said first time period;a second cooling step of cooling said at least one surface of said planar material from said intermediate surface temperature to a final surface temperature less than 60.degree. C. during a second time period using air as a cooling medium; anda reconditioning step of at least partially reconditioning said planar material by exposing said planar material to said vapor mixture during a third time period.
