Further, in the step of dipping treatment, water-soluble resol phenolic resin with the solid content of less than or equal to 30% is used as an adhesive, dipping treatment is carried out in a vacuum pressurization tank, when the liquid absorption amount reaches 120-.
The wood bundle after the blue change degreasing treatment takes the thickness of 3cm as an example, the requirement of 120-130% of liquid absorption amount can be met in 25min, and the gum dipping is fast.
Further, drying the gum-dipped pine wood by a mesh belt dryer at the temperature of 80-85 ℃ and the air speed of 4-5 m/s.
Further, the cold pressing is carried out by a horizontal cold press with the pressure of 700-720kg/cm2。
Furthermore, the curing temperature is 140-145 ℃, and the time is 4-6 h.
Compared with the prior art, the technical scheme of the invention has the beneficial effects that:
1. the invention adopts the treatment process of firstly changing blue and then degreasing, removing color, gumming, pressing and irradiating, shortens gumming treatment time, increases the immersion amount, greatly increases the performance of the recombined wood after forming, and meets the requirements of partial groups on wood safe cases and aesthetic appreciation.
