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...

Embodiment 3

[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 ...

Abstract

The invention relates to the technical field of wood product processing and manufacturing, and discloses a method for eliminating deformation of fraxinus mandshurica wood. The method comprises the following steps that (1) the newly-cut fraxinus mandshurica wood is dried to constant weight, the internal moisture is removed, then impregnation liquid is used to conduct soaking treatment, the problem that the internal fiber structure is greatly affected by temperature changes is solved, on the one hand, kinetic energy of molecular motion is decreased, and on the other hand, the problem of wood instability caused by external force is solved, and the mechanical property is improved; (2) the wood is put into a pressure tank, mixed resin is utilized to conduct soaking processing for the wood under pressure, the surface wetting and infiltration uniformity are improved, and force strength and bearing uniformity of the wood are improved; and (3) under pressing and infiltration, the permeability of the resin is further enhanced. The wood obtained by drying has high waterproofness and yielding resistance, and the problem that existing fraxinus mandshurica wood is prone to deform is solved.

Description

Technical field [0001] The invention belongs to the technical field of wood product processing and manufacturing, and in particular relates to a method for eliminating the deformation of ash wood. Background technique [0002] Flowering Willow, also known as: large-leaf ash tree, large-leaf ash tree, Oleaceae, ash deciduous tree, gray-brown bark, smooth, lobed when old. The winter buds are broad ovate, pointed at the top, dark brown, shiny, and densely covered with brown curly pilose inside. The branches of the year were light yellow, straight and glabrous. The branches of the previous year were dark brown with scattered lenticels. The samara is linear, blunt at the tip, sharply pointed or slightly concave, and the wings extend down to the middle of the nut. The nut is about 1 cm long and slightly raised; with persistent calyx. Flowering period from April to May, fruit period from September to October. Fraxinus mandshurica has no strict requirements on climate and soil. The wo...
