preparation example Construction

[0018] The preparation method of the soaking liquid is as follows: mixing sodium carbonate, sodium chloride, thiophanate-methyl, and water according to the mass ratio of 50-100:500-600:1-2:2500-3000, stirring to dissolve completely.

[0019] The liquid caustic soda is 3-5 mol / L sodium hydroxide solution.

[0020] The concentration of titanium sulfate in the mixed solution of titanium sulfate and iron sulfate is 1-2 mol / L, the concentration of iron sulfate is 0.2-0.5 mol / L, and the pH of the mixed solution is 0.8-1.0.

[0021] The high temperature treatment adopts microwave heating.

[0022] The surface treatment uses a grinder to polish the surface of the willow board, and then sprays a layer of wax.

Embodiment 1

[0024] A kind of preparation method of willow plank, willow log is cut into the willow log section that length is 3m, bark is peeled off by adopting automatic peeling machine, simultaneously air-dries until the moisture content of willow log section is 4%, then soaks in the soaking liquid, The soaking time is 8 hours, the soaking temperature is 49°C, and then soaked in clear water for 2.5 hours, taken out and aired to a moisture content of 3.5%, and then cut into willow boards with a thickness of 2.5cm by a cutting machine, and then placed Put it into liquid carbon dioxide, put it under the pressure of 4.1 atmospheres, and put it at minus 41°C for 40 minutes, then take it out, put it at 45°C for 1.2 hours, soak it in lye for 85s, remove it, drain it and spray it with water Rinse for 1.8 minutes, and then immerse in the mixed solution of titanium sulfate and iron sulfate. The soaking time is 1.5 hours and the temperature is 45°C. Then take it out and drain it, rinse it with wate...

Embodiment 2

[0031] A method for preparing willow boards, comprising cutting willow logs into willow log sections with a length of 3.1 m, peeling off the bark by using an automatic peeling machine, drying the willow logs until the moisture content of the willow log sections is 3.5%, and then soaking in the soaking solution , the soaking time is 8 hours, the soaking temperature is 49°C, and then soaked in clean water for 3 hours, taken out, aired to a moisture content of 4%, and then cut into willow boards with a thickness of 2cm by a cutting machine, and then placed Put it into liquid carbon dioxide, put it under the pressure of 4 atmospheres and the temperature of minus 40°C for 50 minutes, then take it out, put it at 45°C for 2 hours, soak it in lye for 110s, remove it, drain it and spray it with water Rinse for 2 minutes, then immerse in the mixed solution of titanium sulfate and iron sulfate, soak for 1 hour, and the temperature is 45 ° C, then take it out and drain, rinse with water fo...

Abstract

The invention provides a preparation method of willow panels. The method comprises the steps that willow log is cut into willow log sections with the length being 2-4 m; an automatic peeling machine is adopted for peeling bark, and meanwhile, the sections are aired until the moisture content of the willow log sections is 2-5%; then the willow log sections are soaked in a soak solution, then soakedin clear water, taken out and aired; then a cutting machine is adopted for cutting the willow log sections into willow boards with the thickness being 1-3 cm, then the willow boards are placed into liquid carbon dioxide and taken out, and after being held in a place with the temperature being 40-50 DEG C for one to two hours, the willow boards are soaked in alkali liquor and taken out; and the willow boards are soaked in a titanium sulfate and ferric sulfate mixed solution and taken out, the solution is drained form the willow boards, and then the willow boards are placed into a heating chamber for high-temperature treatment, taken out and subjected to surface treatment to obtain the willow panels. According to the preparation method of the willow panels, through pretreatment on the willow panels, survival of injurious insects in the willow panels is avoided, meanwhile, the strength of the willow panels is improved, the service lives of the willow panels are prolonged, and the panelsare in the specific light red and have a certain self-cleaning function.

Description

technical field [0001] The invention relates to a preparation method of willow board, which belongs to the technical field of board processing. Background technique [0002] The morphological characteristics of Salix are as follows: trees or creeping, cushion-like, erect shrubs. Branches cylindrical, pith nearly round. No terminal buds, lateral buds usually clinging to branches, with single bud scales. Leaves alternate, rarely opposite, usually narrow and long, mostly lanceolate, pinnately veined, serrated or entire; petiole short; stipules, mostly serrated, often caducous, rarely persistent. Catkins erect or obliquely spreading, first leaves open, or open at the same time as leaves, rarely open after leaves; bracts entire, hairy or glabrous, persistent, sparsely caducous; stamens 2-many, filaments free or Partially or fully conjoined; glands 1-2 (the one located between the inflorescence rachis and the filament is the ventral gland, and the one near the bracts is the dor...
