  • Method for producing ultra-stable and enhanced solid wood flooring for under-floor heating via surface compression technique
    Patent number: 11833710
    Abstract: A method for producing an ultra-stable and enhanced solid wood flooring for under-floor heating via surface compression technique includes: subjecting, while subjecting a solid wood to surface compression and enhancement, the solid wood to primary stabilization treatment by controlling a temperature of a hot pressing plate to obtain a compressed enhanced solid wood; putting the compressed enhanced solid wood into a heat treatment tank; and subjecting the compressed enhanced solid wood to secondary stabilization treatment by controlling a pressure and a temperature of steam or air in the heat treatment tank and a treatment time to obtain a finished product. The ultra-stable surface-compressed enhanced solid wood flooring produced by the method features high dimensional stability, low set-recovery after water absorption, and desired moisture and heat resistance.
