*** 9760132 Owens This Small Business Innovation Research (SBIR) Phase I project will test a system for simultaneous application of pressure and microwave heating to curable wood assemblies. Conventional curing processes apply heat by means of heated platens, which are in contact with the surface of the product. Curing of the interior regions is slow since wood is a poor thermal conductor. If platen temperatures are increased beyond a certain amount to increase heating of interior regions, scorching and over-curing of the product surface can occur. Microwave energy affords much more uniform volumetric heating and curing, since it is directly and instantly converted to heat throughout a volume, even in the otherwise hard-to-heat interior regions of a product. The additional uniform heating power afforded by microwaves will likely increase production rates substantially and produce more even cures for greater product strength and improved quality. Potential commercial application are expected in the engineered wood industry, where numerous composite products are manufactured with heat-accelerated adhesives. These products include particle board, fiberboard, waferboard, plywood, laminated veneer lumber, oriented strand lumber, and laminated beams ***

*9760132欧文斯这个小型企业创新研究(SBIR)第一阶段项目将测试一种同时对可固化木材组件施加压力和微波加热的系统。传统的固化工艺通过加热的压板来加热，压板与产品表面接触。由于木材的导热性差，内部区域的固化速度很慢。如果将压板温度提高到一定程度以增加内部区域的加热，则可能会发生产品表面的灼烧和过度固化。微波能提供更均匀的体积加热和固化，因为它直接和即时地在整个体积内转化为热，即使在产品的其他难以加热的内部区域也是如此。微波提供的额外的均匀加热功率可能会大幅提高生产率，并产生更均匀的固化，从而提高产品强度和质量。预计在工程木材行业有潜在的商业应用，在该行业，许多复合材料产品都是用热加速粘合剂制造的。这些产品包括刨花板、纤维板、刨花板、胶合板、单板、定向刨花板和层压梁*。
