Embodiment 1

[0017] A method for processing pine wood, comprising the following steps:

[0018] (1) Put pine logs in the sun for 3 days, remove part of the moisture, and soak them in a degreasing agent for 4 hours. The degreasing agent is made of the following ingredients in terms of mass percentage: tripropylene glycol n-butyl ether accounts for 3.5% , Isopropanol 2.3%, Ethanolamine 1.2%, Sodium Lauryl Sulfate 1.0%, Sodium Silicate 0.8%, Trisodium Phosphate 0.5%, Sodium Carbonate 0.3%, Sodium Hydroxide 0.1%, Alumina powder accounts for 0.03%, and the rest is water;

[0019] (2) Immediately after degreasing, rinse the wood surface with water at 30°C, then wrap the wood surface with plastic wrap for 2 layers, and use a fumigant to evenly fumigate for 1 hour at a temperature of 70°C. The fumigant used is made of camphor bark , mugwort leaves, tea bark, and hyssop mixed with essential oils, after fumigation, heat the wood under steam at 100°C for 10 minutes;

[0020] (3) Put the steam-heate...

Embodiment 2

[0026] A method for processing pine wood, comprising the following steps:

[0027] (1) Put pine logs in the sun for 4 days, remove part of the water, and soak them in degreasing agent for 5 hours. The degreasing agent is made of the following ingredients in terms of mass percentage: tripropylene glycol n-butyl ether accounts for 3.55% , Isopropanol 2.4%, Ethanolamine 1.25%, Sodium Lauryl Sulfate 1.1%, Sodium Silicate 0.9%, Trisodium Phosphate 0.6%, Sodium Carbonate 0.4%, Sodium Hydroxide 0.15%, Alumina powder accounts for 0.04%, and the rest is water;

[0028] (2) Rinse the wood surface with 35°C water immediately after degreasing, then wrap the wood surface with two layers of plastic wrap, and use fumigant to evenly fumigate for 1.5 hours at a temperature of 75°C. The fumigant used is made of camphor bark , mugwort leaves, tea bark, and hyssop mixed with essential oils, after fumigation, heat the wood under steam at 100°C for 15 minutes;

[0029] (3) Put the steam-heated wo...

Embodiment 3

[0035] A method for processing pine wood, comprising the following steps:

[0036] (1) Put pine logs in the sun for 5 days, remove part of the moisture, and soak them in degreasing agent for 6 hours. The degreasing agent is made of the following ingredients in terms of mass percentage: tripropylene glycol n-butyl ether accounts for 3.6% , Isopropanol 2.6%, Ethanolamine 1.3%, Sodium Lauryl Sulfate 1.2%, Sodium Silicate 1.0%, Trisodium Phosphate 0.7%, Sodium Carbonate 0.5%, Sodium Hydroxide 0.2%, Alumina powder accounts for 0.06%, and the rest is water;

[0037] (2) Immediately after degreasing, use 40°C water to rinse the wood surface, then wrap the wood surface with three layers of plastic wrap, and use fumigant to evenly fumigate for 2 hours. The fumigation temperature is 80°C. The fumigant used is made of camphor bark , mugwort leaves, tea bark, and hyssop mixed with essential oils, after fumigation, heat the wood under steam at 100°C for 20 minutes;

[0038] (3) Put the s...

Abstract

The invention relates to the technical field of woodwork processing and manufacturing, and discloses a processing method of pinus sylvestris wood. The method comprises the following steps that (1) pinus sylvestris log is naturally aired to remove partial moisture, and then a degreaser acts on the wood to improve a degreasing effect, wherein the used degreaser is good in permeability, can bring out internal grease of pinus sylvestris, and minimizes an influence of further processing; (2) the wood is treated by a fumigant after grease cleaning, so that vermin-proof and moth-proof effects of the wood can be improved, and what is important is that effects of improving the bending strength, the bending elastic modulus and the parallel-to-grain compressive strength of the pinus sylvestris wood are exerted; and (3) the wood stabilized by steam is treated under high-temperature pressurization, so that an inclusion of the wood is volatilized, the equilibrium moisture content is reduced, the dimensional stability is greatly improved, the parallel-to-grain shear strength is improved to some extent, the possibility of deformation is low, the compressive strength and the hardness are improved, and an environmental protection property is good.

Description

technical field [0001] The invention belongs to the technical field of wood product processing, and in particular relates to a method for processing pine wood. Background technique [0002] Pinus sylvestris, evergreen tree, 15-25 meters high, up to 30 meters, crown oval or conical. The trunk is straight, the bark below 3-4 meters is dark brown, and the scales are deeply divided. The leaves are hard, often slightly twisted, and the apex is sharp. Monoecious plants, male cones are oval, yellow, gathered in the lower part of the current year's branches; female cones are spherical or oval, purple-brown. Cones oblong. The scale shield is rhomboid, with vertical and transverse ridges, and the scale navel is tumor-like. Seeds are small, yellow, brown, and dark brown, with membranous wings. Produced in the Daxing'an Mountains, Heilongjiang, China, at an altitude of 400-900 meters and in the sand dunes to the west and south of Hailar. It can be used as garden ornamental and gree...
