Abstract

DC60 (12/02/42) Pressed sheets for the production of resin impregnated paper decorative laminates. With alumina particles on Its compressed surface. Was coated with diboride Selected from a group containing hafnium diboride, molybdenum diboride, tantalum diboride, titanium diboride, tungsten diboride, vanadium myboride. Or zirconium diboride Or a mixture of these substances for action Compression plates that resist abrasion Using a process in which the sheet is pressed And the sputtering head is moved Relative To provide a scanning speed that is sufficient to provide a gradient of heat in a compressed sheet of 50 ° F. Or less to provide reduced internal stress And heat dissipation is not very local Up all over the sheet Pressed sheets for the production of decorative laminates from resin impregnated paper. With alumina particles on its compressed surface Was coated with diboride Selected from a group containing hafnium diboride, molybdenum diboride, tantalum diboride, titanium diboride, tungsten diboride, vanadium miboride. Dehydrate, or zirconium diboride Or mixtures of these substances for the action of compression-resistant sheets Using a process in which the compression plate and the pusher head are moved relative to each other To provide a scanning speed sufficient to provide a thermal gradient in the compression plate 50 ° F or less to provide reduced internal stress. And more non-local heat distribution throughout that compression plate
