Abstract
The present invention relates to a type of wood section material manufacturing method, especially with respect to soft wood section material and its manufacturing method. It belongs to wood processing field. This invention is achieved by the following technical plans: a type of wood section material manufacturing method includes the following steps: (1) wood preparation; (2) drying; (3) Polishing; (4) Hot pressing, which is to use two hot pressing boards with 140-200° C. to firmly press two surfaces of panel blank material; (5) Pre-carbonization, which pre-carbonize the panel blank material under 160° C. and 200° C.; (6) Carbonization, which carbonize the panel blank material between 200° C. and 225° C.; (7) Cooling; and (8) Moisture content control. This invention is particularly suitable to make wooden floor boards and office furniture.
