Summary of the invention:

The purpose of this invention is to provide a kind of demand that has not only solved very huge indoor timber ornament materials, but also can increase farmers' income, alleviate felling, preserve the ecological environment, meet the direction of human kind sustainable development ancient and well-known trees; Save water, electricity, vapour, dying material, artificial etc. timber ornament materials biology enzyme pre-treating method.

Technical solution of the present invention is: a kind of timber ornament materials biology enzyme pre-treating method is characterized in that: at first timber is carried out flaking; Again wood flake is carried out kiering, in kiering liquid, add the biology enzyme of relative wood flake weight 1～4%; The kiering condition: bath raio 1: 10～15,85～100 ℃ of temperature, are washed at last at 45～90 minutes time.

The hydrogen peroxide that can add relative wood flake weight 1～4% during kiering described in the present invention is simultaneously bleached processing.Can add simultaneously dyestuff as required during kiering, to the wood flake processing of dyeing.Biology enzyme is selected clean cotton enzyme GX1 of hundred victorys or scutching cotton teacher 100T for use.

Beneficial effect of the present invention is: but with fast growing tree one aspen (silver birch) of samsaras such as deserted mountain, wild country, roadside plantations etc., or from fast growing tree one A Yousi of African import cheapness etc., be processed into ply by slicing, need the ply of color and luster dullness be floated the processing after stain and makes imitative natural ancient and well-known trees through boiling according to people, or the color and luster of timeworn furniture modelled after an antique, it is compounded in the natural indoor timber ornament materials that forms imitative ancient and well-known trees on the glued board.Wood chip after maybe will dyeing forms the artificial timber of holding different color and luster and texture after gluing together, kept texture, respiratory, the transparency and organic texture of timber, and makes the inside of timber also can level dyeing.And bleaching and dyeing boiling processing through high temperature, fully removed the internal stress in the timber, make the artificial timber of making indeformable, do not ftracture.Like this; not only solved the demand of very huge indoor timber ornament materials; and can be in China's west desertification region or some deserted mountains, samsara plantation aspens (silver birch) such as wild country, roadside as industry to increase farmers' income; alleviate felling to ancient and well-known trees; preserve the ecological environment, meet the direction of human kind sustainable development.Owing to except containing components such as cellulose, hemicellulose, lignin, also contain some natural impuritys that dye on the influential dyestuff in the natural timber.Adopt high-tech biology enzyme treatment technology, float or boil and bleaching and dyeing one-step technology by boiling, can remove pectin in the timber effectively, wax, ash content, impurity such as natural colouring matter, waterabsorbing capacity of wood and dyeing Dry Sack rate and uniformity are all had clear improvement, do not need repeatedly boiling, saved water greatly,, vapour, chemical agent, and do not use chemical substances such as caustic soda, sodium metasilicate in the processing procedure, can be after the processing without washing, reduce quantity of wastewater effluent greatly, thereby reach the shortening production process, improve the quality of products, reduce production costs, reduce the purpose of environmental pollution, have very useful social benefit and economic benefit.
