1) A continuous impregnation technology for wood-based reconstituted materials was invented. Oriented large fiber bundles are loaded into a continuous impregnation tank, and the adhesive is directionally injected through the linear and dot-shaped convex teeth of extrusion rollers. By adjusting the gap between the impregnation rollers to precisely control the impregnation dosage, this technology achieves a 20% increase in production efficiency, a 30% reduction in drying energy consumption, and reductions of 18.77% and 26.15% in the water absorption width expansion rate and water absorption thickness expansion rate, respectively; 2) A continuous impregnation apparatus for wood-based reconstituted materials was developed. Online monitoring of key components including the impregnation tank, impregnation rollers, transmission device, glue tank temperature controller, pH regulator, solid content monitor and other modules enables the realization of continuous impregnation; 3) Low-molecular-weight phenolic resin was synthesized. Using molecular design, directional regulation and multi-component compounding approaches, the as-synthesized low-molecular-weight phenolic resin has a viscosity of 138 mPa·s, a solid content of 55.20%, free formaldehyde content of 0.13%, free phenol content of 0.15%, and water solubility of 11.93 times.
