Embodiment 1

[0026] First configure the wood veneer blue treatment agent, the wood veneer blue treatment agent is composed of the following mass concentrations of substances mixed: sodium chloride 1%, NH 2 SO 3 H 0.04%, HOOCCOOH 0.7%, CH 3 COOH 0.2%, H 3 PO 4 0.5%, ethylenediaminetetraacetic acid 0.2%, sodium dihydrogen phosphate 0.1%, solvent is water. H 3 PO 4 Prepare H with a pH of 4 and a temperature of 45°C with water 3 PO 4 solution, and then pour the wood veneer deblueing treatment agent into CH 3 PO 4 The solution is prepared into a temporary liquid, and the wood veneer deblueing treatment agent and H in the temporary liquid 3 PO 4 The volume ratio of the solution is 1:3. During treatment, first prepare sodium hydroxide water into a sodium hydroxide solution with a pH value of 9, then immerse the wooden veneer for 1 hour for pretreatment, and then immerse the pretreated veneer in the liquid for decolorization , the treatment time is 2 hours. During the decolorization tr...

Embodiment 2

[0028] With embodiment 1, difference is that described drying adopts solar drying; After drying, moisture content is controlled at 5%.

Embodiment 3

[0030] First configure the wood veneer blue treatment agent, the wood veneer blue treatment agent is composed of the following mass concentrations of substances mixed: sodium chloride 2%, NH 2 SO 3 H 0.11%, HOOCCOOH 0.8%, CH 3 COOH 0.3%, H 3 PO 4 0.7%, 0.3% ethylenediaminetetraacetic acid, 0.3% sodium dihydrogen phosphate, and the solvent is water. H 3 PO 4 Prepare H with a pH of 5 and a temperature of 50°C with water 3 PO 4 solution, and then pour the wood veneer deblueing treatment agent into CH 3 PO 4 The solution is prepared into a temporary liquid, and the wood veneer deblueing treatment agent and H in the temporary liquid 3 PO 4The volume ratio of the solution is 1:5. When processing, first prepare sodium hydroxide water into a sodium hydroxide solution with a pH value of 10, then immerse the wooden veneer for 1.5 hours for pretreatment, and then immerse the pretreated veneer in the liquid for decolorization Treatment, the treatment time is 3 hours, during t...

Abstract

The invention relates to a wood blue removal processing method, belonging to the technical field of wood processing. A blue removal processing agent for a wooden single plate and a blue removal method of the wooden single plate are provided; the blue removal processing agent for wooden single plate is prepared by mixing the materials according to the following mass concentrations: 1-3% of NaCl, 0.04-0.18% of NH2SO3H, 0.7-0.9% of HOOCCOOH, 0.2-0.4% of CH3COOH, 0.5-0.9% of H3PO4, 0.2-0.4% of ethylenediamine tetraacetic acid and 0.1-0.5% of sodium dihydrogen phosphate, and the dissolvent is water. The blue removal processing agent for wooden single plate and the blue removal method of wooden single plate can solve the blue removal of wooden single plate, and the method also has uniform decolorization; the decoloration method is simple, efficient and low-cost; the production process is environment-friendly without pollution, and has little damage to wood.

Description

technical field [0001] The invention relates to a wood bluing treatment agent and a wood bluing treatment method, belonging to the technical field of wood treatment. Background technique [0002] At present, most of the logs used for decorative materials are artificial fast-growing materials, mainly including Ayous, poplar, basswood, etc. In the actual production process, due to log storage and mechanical processing, a large number of wooden veneers appear blue , have a strong impact on the utilization of raw materials and the quality of manufactured products. The blue color of wood is due to the adhesion of iron, because the phenolic components in the wood contact with iron, and a chemical reaction occurs to form blue substances, which leads to material color pollution. In the prior art, the wood decolorization treatment method is as described in the Chinese invention patent with the publication number CN101691042A (2010-04-07), but it has been proved by production p...
