Embodiment 1
[0016] A method for eliminating the deformation of Fraxinus mandshurica wood includes the following steps:
[0017] (1) Put the freshly cut ash wood in an oven preheated at 100°C, and dry it until the quality is constant. The drying setting temperature is 2°C per hour. After drying, take out the wood and place it at temperature Soak in the dipping solution at 50℃ for 2 hours. The dipping solution is made of the following components in terms of mass percentage: polybutyl methacrylate emulsion accounts for 3.5%, dehydrated trisitol trioleate accounts for 2.4%, and vinyl acetate accounts for 1.2 %, tributyl phosphate accounted for 0.6%, carboxymethyl cellulose accounted for 0.4%, sodium bicarbonate accounted for 0.2%, ammonium persulfate accounted for 0.1%, and the remainder was water;
[0018] (2) Take out the soaked wood, dry the surface dipping liquid, dry it for 2 days and then bake it on a slow fire. The temperature is controlled at 110°C until the weight is constant. Then the wo...

[0025] A method for eliminating the deformation of Fraxinus mandshurica wood includes the following steps:
[0026] (1) Put the freshly cut Fraxinus mandshurica wood in an oven preheated at 102°C, and dry it until the quality is constant. The drying setting temperature is 2°C per hour. After drying, take out the wood and place it at temperature. It is immersed in the impregnating solution at 55℃ for 2.5 hours. The impregnating solution is made of the following ingredients in terms of mass percentage: polybutyl methacrylate emulsion accounts for 3.7%, dehydrated trisitol trioleate accounts for 2.5%, and vinyl acetate accounts for 1.3 %, tributyl phosphate accounts for 0.7%, carboxymethyl cellulose accounts for 0.5%, sodium bicarbonate accounts for 0.25%, ammonium persulfate accounts for 0.2%, and the remainder is water;
[0027] (2) Take out the soaked wood, dry the surface dipping liquid, dry it for 2 days and then bake it on a slow fire. The temperature is controlled at 115°C unti...

[0034] A method for eliminating the deformation of Fraxinus mandshurica wood includes the following steps:
[0035] (1) Put the freshly cut Fraxinus mandshurica wood in an oven preheated at 105°C, and dry it until the quality is constant. The setting temperature for drying is 3°C per hour. After drying, take out the wood and place it at temperature It is immersed in an immersion solution at 60°C for 3 hours. The immersion solution is made of the following components in terms of mass percentage: polybutyl methacrylate emulsion accounts for 4.0%, trisitol trioleate accounts for 2.6%, and vinyl acetate accounts for 1.4 %, tributyl phosphate accounted for 0.8%, carboxymethyl cellulose accounted for 0.6%, sodium bicarbonate accounted for 0.3%, ammonium persulfate accounted for 0.3%, and the remainder was water;
[0036] (2) Take out the soaked wood, dry the surface dipping liquid, dry it for 3 days and then bake it on a slow fire. The temperature is controlled at 120°C until the weight ...
