Embodiment 1

[0013] A method for processing mandshurica wood in furniture production, specifically, comprising the following steps:

[0014] Step 1: Put the cut ash wood into the prepared softener and pressurize and seal it for soaking. The pressure soaking pressure is 1.25MPa, the soaking time is 16 minutes, and the soaking temperature is 95°C. After soaking, put it in an oven at 66°C Drying in medium for 12 hours, the softener is made of the following components in terms of mass percentage: OP-10 accounts for 0.30%, ammonium persulfate accounts for 0.8%, polyvinyl alcohol accounts for 1.5%, sodium carbonate accounts for 0.75%, triethanolamine accounts for 0.35% , calcium carbonate accounts for 0.8%, lauryl acrylate accounts for 0.2%, and the rest is water;

[0015] Step 2: Preparation of penetrating agent: Mix 36 grams of tetraethyl orthosilicate and absolute ethanol at a mass ratio of 1.5:1.9, stir evenly, add 20 milliliters of deionized water, add 1.5 grams of boron oxide, 2.6 grams o...

[0023] Step 2: Preparation of penetrating agent: Mix 37 grams of tetraethyl orthosilicate and absolute ethanol at a mass ratio of 1.5:2.0, stir evenly, add 25 milliliters of deionized water, add 1.6 grams of boron oxide, 2.8 g...

Embodiment 3

[0029] A processing method for ash wood in furniture production, specifically, comprising the following steps:

[0030]Step 1: Put the trimmed ash wood into the prepared softener and pressurize and seal it for soaking. The pressure soaking pressure is 1.30MPa, the soaking time is 20 minutes, and the soaking temperature is 97°C. After soaking, put it in an oven at 70°C. Drying in medium for 16 hours, the softener is made of the following components in terms of mass percentage: OP-10 accounts for 0.32%, ammonium persulfate accounts for 1.0%, polyvinyl alcohol accounts for 1.7%, sodium carbonate accounts for 0.85%, triethanolamine accounts for 0.45% , calcium carbonate accounts for 1.0%, lauryl acrylate accounts for 0.4%, and the rest is water;

Abstract

The invention relates to a treating and processing method of fraxinus mandshurica wood in furniture production. The method comprises the following steps that fraxinus mandshurica wood is placed in a prepared softening agent to be soaked for 16-20 min, and then a prepared penetrating agent is used for conducting dipping treatment on the fraxinus mandshurica wood. Adsorption of the interior of the fraxinus mandshurica wood to dye can be improved, and the problems that the dye stays on the surface to color the fraxinus mandshurica wood , the dyeing rate is low, dyeing is uneven and fading occurseasily are solved. The treating and processing flow is simple, environmentally friendly and low in cost, the treated fraxinus mandshurica wood has an excellent dyeing effect, the colors of various rare wood can be imitated, the dyeing rate is high, use of dye is reduced, the dyeing temperature is low, the dyeing time is shortened, and the method has important significance in reducing environmentalpollution. Moreover, dyeing is firm, the durability is good, dye seepage and fading are not likely to happen, and the sense of reality of the wood grain color is achieved.

Description

technical field [0001] The invention relates to the technical field of furniture wood treatment and processing, in particular to a treatment and processing method of ash wood in furniture production. Background technique [0002] Mandshurica mandshurica has a round shape, tall and straight, strong adaptability, and has the ability to resist severe cold, drought, smoke and dust, diseases and insect pests, and is an excellent greening and ornamental tree species. At the same time, it can form a mixed forest with many coniferous and broad-leaved tree species to form a forest ecosystem with a composite structure, which is of great significance and effect on improving the water conservation of the entire forest, maintaining water and soil, and preventing environmental degradation. Ash wood has very good overall strength properties, good shock resistance and steam bending strength. Heartwood has moderate penetration resistance to preservative treatments, white wood has penetratio...
