Abstract

The invention discloses an improvement method for imitating black walnut. The invention comprises the following steps that: (1) timber optimization includes that: the sawn timber with the similar pattern of the black walnut is selected, the depth of the sawn timber is not larger than 6 cm, and the length and the depth are not limited; (2) improvement processing includes that: the sawn timber is put in the processing tank, the improvement liquid is added according to the certain volume, and the processing is performed for a certain time under a certain temperature; after the processing is accomplished, the steam is exhausted, and the sawn timber is taken out. The improvement of the invention which is very lifelike to the American black walnut can be used for replacing the American black walnut to perform high-class decoration. The invention is easy to realize, the operation is convenient, the production cost is low, thereby being more important, the utilization of the technology does not produce waste water, the wood added value enhanced, and more employment posts are created, and the invention is advantageous in the promotion of the harmonious development of artificial forest resources on the country.

Description

The modification method of a kind of imitative black walnut

Technical field

The present invention relates to the modification method of a kind of imitative black walnut.

Background technology

Timber be in the three big construction materials (reinforcing bar, cement, timber) with the natural material of the tool affinity of the mankind, thereby be widely used in fields such as building, furniture, floor.Because high-quality wildwood timber resources is limited, costs an arm and a leg, and can not satisfy the wilderness demand of China's furniture manufacturing, construction and decoration and wood-based plate secondary operations fully, therefore, global wood industrial raw material supply just progressively turns to the artificial tree aptitude source of using.Artificial forest growth is fast, become a useful person early, thereby material is more loose, uneven color, and tone is dark and gloomy, and timber is restricted its application at aspects such as building, decorations, furniture, wood-based plate processing in the variable color of storing, produce in the process, pollution etc. in addition.

Wood staining is to realize effective ways common or low-quality timber simulation rare tree timber, particularly to quick-growing plantation timber, by technology processing such as dyeing, simulation wood grains, can eliminate timber heart sapwood, the aberration between late wood and the swirl grain early, obviously improve the ornamental and added value of timber.Therefore, in recent ten years, the staining technique of wood materials enjoys attention, and dyeing research constantly advances.For expanding utilizing approach, increasing its value of artificial forest wood.The present invention discloses a kind of efficient modification method of a kind of imitative black walnut on the basis that the inventor studies for a long period of time.

Summary of the invention

Technical problem to be solved by this invention provides and a kind ofly is easy to realize, the modification method of easy to operate, imitative black walnut that production cost is low.

In order to solve the problems of the technologies described above, the modification method of imitative black walnut provided by the invention,

(1), timber is preferred: select the sawn timber of linden, pine or elm, sawn timber thickness is not more than 6cm, and its length and width are not limit;

(2), improved treatment: sawn timber is placed in the process tank, and according to the volume ratio of timber and salpeter solution be the ratio of 1:0.5～1:8 to add mass percent concentration be 0.01%～5% salpeter solution, handle 2～8h down at 105～150 ℃ then and get final product; Processing after finishing is emitted steam, takes out sawn timber and gets final product.

Adopt the modification method of the imitative black walnut of technique scheme, can impel the timber chromophoric group to change, make wood color present the color of Adaptive Mechanisms of American Black Walnut timber, obviously improve the ornamental and added value of timber, realized common or low-quality timber simulation rare tree timber, the improvement of manufacturing of the present invention and Adaptive Mechanisms of American Black Walnut timber are very true to nature, can substitute Adaptive Mechanisms of American Black Walnut wood and carry out the top grade decoration.This invention have be easy to realize, easy to operate, production cost is low, what is more important utilizes this technology not produce waste water, improves the added value of timber, job-creation helps promoting the harmonious development of the artificial forest products industry of China.

In sum, the present invention be a kind ofly be easy to realize, the modification method of easy to operate, imitative black walnut that production cost is low.

The specific embodiment

Can further be expressly understood the present invention by specific embodiments of the invention given below, but following embodiment is not a limitation of the invention.

Embodiment 1:

The sawn timber of selection and the close linden of black walnut decorative pattern, sawn timber thickness 6cm, its length and width are not limit; Sawn timber is placed in the process tank, and according to the volume ratio of timber and salpeter solution be 1:0.5 to add mass percent concentration be 5% salpeter solution, handle 8h down at 105 ℃ then and get final product.Processing after finishing is emitted steam, and the taking-up sawn timber gets final product.After the processing, wood color presents the color of Adaptive Mechanisms of American Black Walnut timber, and the physico-mechanical properties variation is no more than 8%.Embodiment 2:

The sawn timber of selection and the close pine of black walnut decorative pattern, sawn timber thickness 3cm, its length and width are not limit; Sawn timber is placed in the process tank, and according to the volume ratio of timber and salpeter solution be 1:1 to add mass percent concentration be 0.01% salpeter solution, handle 2h down at 150 ℃ then and get final product.Processing after finishing is emitted steam, and the taking-up sawn timber gets final product.After the processing, wood color presents the color of Adaptive Mechanisms of American Black Walnut timber, and the physico-mechanical properties variation is no more than 8%.Embodiment 3:

The sawn timber of selection and the close elm of black walnut decorative pattern, sawn timber thickness 5cm, its length and width are not limit; Sawn timber is placed in the process tank, and according to the volume ratio of timber and salpeter solution be 1:8 to add mass percent concentration be 0.1% salpeter solution, handle 4h down at 130 ℃ then and get final product.Processing after finishing is emitted steam, and the taking-up sawn timber gets final product.After the processing, wood color presents the color of Adaptive Mechanisms of American Black Walnut timber, and the physico-mechanical properties variation is no more than 8%.
