Abstract

The artificial wood utilizes woody material of small-diameter timber and bamboo, and their branch and twig, cotton stalk and similar material. After pretreatment including the steps of trimming, cutting, peeling and softening, then the material is dissociated through kneading and separation into small cellulose bundles which are further processed through the steps of drying, gluining, spreading, and hot pressing into the artificial wood. The artificial wood is suitable for use in various fields.

Description

Sham wood

Content of the present invention belongs to wood materials manufacturing technology field, relates to a kind of novel wooden material that replaces natural timber to use.

Timber is the human lives and gives birth to and build necessary a kind of important raw and processed materials that along with the raising of development of economic construction and living standards of the people, people are increasing to the demand of timber, thereby cause the contradiction day between the timber supply and demand to be becoming tight.In order to alleviate the nervous situation of the particularly big footpath of timber level wood supply, people have adopted various measures, as with steel for wood, with plastics for wood and greatly develop wood-based panel product etc.But because the own characteristic of these materials, be doomed that they can't fundamentally substitute texture, architectural characteristic and the advantages such as its insulating properties, resonance qualitly and high quality coefficient of natural timber, especially natural timber these materials did not substitute especially.A kind of new product-reorganization wood (Scrimber) has appearred in late nineteen eighties in the timber family, its appearance is called " one of the most soul-stirring breakthrough in wood utilization aspect ".Reorganization wood be utilize low-quality raw materials such as small diameter grade low-grade wood, thinnings, brush wood through roll over stranding equipment be processed into laterally do not rupture, vertical loose and staggered continuous big wooden Shu Mucai, quick-fried through doing again, mat formation and the wooden material of use that processes such as hot pressing forms, the appearance of this technology has been opened up a new way for the particularly big footpath of alleviation timber level structure with the nervous situation of material undoubtedly.The processing technology of reorganization wood imagines fairly simple, but has suitable difficulty when specifically implementing, and its reason one is that the direction that is difficult to keep wood fibre to arrange in whole process of production is not upset; The 2nd, because in the wooden production process of reorganization, require to remove the defective of raw material, as knot etc., but remove the uniformity that product after the defective is difficult to keep structure; Three is because production process itself all has the restriction of strictness to the diameter of raw material and taperingness etc.Due to above-mentioned difficulties, make reorganization wood be difficult in the application that puts it in real life and the production.

The objective of the invention is to the problem that exists at the reorganization wood technology, provide a kind of and utilize low-quality raw materials to process and production technology is simple, novel wooden material-sham wood of being easy to realize.

Sham wood of the present invention is that a kind of small diameter grade material, brush wood or raw materials such as path bamboo wood, cotton stalk of utilizing have single layer structure or a three-layer structure wooden material by what specific production technology processed, and the technology of producing this material comprises following program:

A. get the raw materials ready and send the boiling pond to soften processing after preliminary treatment-with raw material is pruned, blocked, removes the peel;

B. the multistage rolling rubbing roller of fiber separation-utilize dissociates into netted wood bundle with the raw material after preprocessor, utilizes defibrator that netted wood bundle is separated into independently fubril bundle again;

C. do quick-fried-fubril bundle after will separating and send into drying machine and carry out drying, its moisture content is controlled in 5～8% scopes;

D. applying glue-utilize adhesive to drying and cooled fubril Shu Jinhang spray glue, resin added accounts in 10～16% (solid) scope of dry fiber weight;

E. mat formation, the raw material of hot pressing-will do applying glue after handling mat formation into individual layer (containing grading structure) or three layers of blanket on request, and be hot-forming then;

F. post-production-to be hot pressed into section bar cut out cut, fine finishining, covering with paint, incrustation etc.

Sham wood material of the present invention with the difference of reorganization wood material on production technology is: the wood of recombinating is only raw material to be dissociated into netted wood bundle, does not promptly upset the orientation of fiber, the more netted wood of some volumes is restrainted the plate that reconfigures and make; And sham wood not only will dissociate into raw material netted wood bundle, and need utilize defibrator that netted wood bundle further is separated into thinner fubril bundle again, even the orientation of fiber is upset earlier in process of production, when mating formation moulding, again as required or make fiber still be confusing shape to arrange and make the sham wood of single layer structure, or make the sandwich layer fiber keep confusing shape arrange and up and down surface fibre make the three-decker sham wood by vertically fitly lining up artificially.

Accompanying drawing 1 is the structural representation of single layer structure sham wood.This structure sham wood does not require that fiber arranges in an orderly manner, thereby after the operation of mating formation, product art layer fiber is confusing arrangement.

Accompanying drawing 2 is the structural representation of three-decker sham wood.The sandwich layer fiber of the sham wood of this structure can be crisscross mix and arrange, but surface fibre then requires vertically to arrange in an orderly manner up and down, therefore when mating formation, need to make it on the material table, to present the texture of similar wood artificially with the surface fibre marshalling.

In the practical application, the single layer structure sham wood can be used for making the goods of veneer or opaque covering with paint, and the three-decker sham wood can be used for making the goods of transparent coating.

Utilize the sham wood pressing that mould is pressed into and utilize other to be laminated with sham wood that material makes according to above-mentioned production technology and be laminated with material and should belong in the claim scope of the present invention.

Producing man-made Wood, required small investment, instant effect, is the weak point carried out in cotton area of very suitable vast forest zone, bamboo district and producing, flat, project soon.Actual detected and result on trial according to relevant department and designer show, the man-made Wood that adopts production technology described herein to produce has face (face can be made into the similar wood texture) attractive in appearance, material is even, intensity is high, the good advantages such as (split hardly and do not stick up) of dimensional stability, and its processing characteristics and natural timber are approaching.For this reason, greatly developing sham wood produces, not only can accomplish the big usefulness of small wood, short material long with, the excellent usefulness of bad material, turn waste into wealth, can bring considerable economic and social benefit to enterprise, and will make the situation of China's wood supply shortage obtain greatly change.

Claims
