Abstract: System and method for diffusing chemicals rapidly and evenly into and through fibrous material, such as wood. Chemicals are introduced into the fibrous material by applying the chemicals to the fibrous material. After treating the fibrous material with the chemicals, the fibrous material is maintained under low-headspace conditions. Thermal energy or dielectric heating, such as microwave or radio frequency energy, is applied to the fibrous material. As a result, the chemicals are able to distribute evenly and quickly throughout the fibrous material.

Abstract translation: 快速均匀地将化学物质扩散到纤维材料（如木材）中的系统和方法。 通过将化学品施加到纤维材料上将化学品引入纤维材料中。 在用化学品处理纤维材料之后，纤维材料保持在低顶空条件下。 将热能或电介质加热，如微波或射频能量施加到纤维材料上。 因此，化学品能够均匀且快速地分布在整个纤维材料中。
