Embodiment 1
[0014] Take a poplar veneer with a thickness of 0.5mm, a length of 100mm, and a width of 100mm, adjust the moisture content to 12% after drying, place it on the feed conveyor belt of the cold plasma treatment system, adjust the distance between the two electrode rollers, Keep the distance between the surface of the wooden veneer and the electrode at 0.5 mm. Turn on the power supply, adjust the processing power to 1kW, and make the working gas between the electrodes generate cold plasma through dielectric barrier discharge. The wood veneer passes through four pairs of discharge electrode rollers at a speed of 2m / min. The working gas between the first two pairs of electrodes is air, and the working gas between the last two pairs of electrodes is ammonia. The wooden veneer treated with cold plasma is dyed by immersing it in the prepared direct dyeing solution, the temperature of the dyeing solution is 90° C., and the dyed wooden veneer is obtained after washing and drying. Compa...
Embodiment 2
[0016] Take a poplar veneer with a thickness of 3.0mm, a length of 100mm, and a width of 100mm, adjust the moisture content to 8% after drying, place it on the feeding conveyor belt of the cold plasma treatment system, adjust the distance between the two electrode rollers, Keep the distance between the surface of the wooden veneer and the electrode at 1 mm. Turn on the power supply, adjust the processing power to 3.5kW, and make the working gas between the electrodes generate cold plasma through dielectric barrier discharge. The wood veneer passes through four pairs of discharge electrode rollers at a speed of 10m / min. The working gas between the first two pairs of electrodes is air, and the working gas between the last two pairs of electrodes is ammonia. The wooden veneer treated with cold plasma is dyed by immersing it in the prepared direct dyeing solution, the temperature of the dyeing solution is 90° C., and the dyed wooden veneer is obtained after washing and drying.

Embodiment 3
[0018] Take a poplar veneer with a thickness of 5.0mm, a length of 100mm, and a width of 100mm, adjust the moisture content to 2% after drying, place it on the feeding conveyor belt of the cold plasma treatment system, adjust the distance between the two electrode rollers, Keep the distance between the surface of the wood veneer and the electrodes at 1.5 mm. Turn on the power supply, adjust the processing power to 6kW, and make the working gas between the electrodes generate cold plasma through dielectric barrier discharge. The wood veneer passes through four pairs of discharge electrode rollers at a speed of 20m / min. The working gas between the first two pairs of electrodes is air, and the working gas between the last two pairs of electrodes is ammonia. The wood veneer treated with cold plasma is dyed by immersing it in the prepared direct dye solution, the temperature of the dye solution is 80°C, and the dyed wood veneer is obtained after washing and drying.
