Abstract
A wood substrate or member is included, having an increased density with respect to natural, untreated wood. The process includes drying the wood prior to application of heat and pressure, which are controlled to reduce or eliminate color change on a surface of the wood member where heat and pressure are applied.
Claims16
A veneer and core assembly for a flooring component, the veneer and core assembly formed by:
- (a) preheating a wood member by introducing the wood member to a temperature in a range of about 250° F. to about 500° F., wherein the preheating is for a time sufficient to reduce moisture content of the wood member to between 0 to about 2% and to obtain a core temperature of the wood member of about 250° F. to about 500° F.;
- (b) after reducing the moisture content of the wood member to between 0 to about 2% and obtaining the core temperature of the wood member of about 250° F. to about 500° F., applying pressure to the wood member for a single press cycle for a press time of about 30 seconds to about 10 minutes, wherein heat is applied during the applying of pressure to maintain the core temperature during the applying of pressure in a range of about 250° F. to about 500° F.;
- (c) providing a post-treatment conditioning of the wood member to provide a treated wood member;
- and
- (d) applying the treated wood member, as a veneer, to a core material to form the veneer and core assembly.
