Abstract
The invention discloses a technology for producing a novel technical wood, which comprises the steps as follows: a, a blank veneer is manufactured through rotary-cut or slicing, and is sheared into required size to obtain a veneer A; b, the veneer A is subjected to carbonizing heat treatment at different carbonizing temperatures to obtain a required wood color, and a veneer B is obtained; c, the veneer B is subjected to gumming, die pressing and batten health preservation treatment sequentially, and a batten C is obtained; and d, the batten C is sawed into required decoration pattern and size to obtain a finished product. The product produced by the technology disclosed by the invention has uniform wood color and moisture content, can expand the thicknesses of the veneers, improve the production efficiency, and prevent the environmental pollution caused by chemical reactions simultaneously.
Description
Technical field
The present invention relates to a kind of production method of veneer, particularly a kind of production technology of new technology wood.
Background technology
Recombinant Wood is with common tree lumber (fast growing wood etc.) for raw material utilize bionics principle, by shearing timber, dyeing, new decorative material that a kind of performance of recombinant production is more superior.The technological process of production of typical Recombinant Wood is: product design → veneer manufacture → veneer shearing → veneer toning → veneer drying → veneer gluing → compression molding → saw lumber → sawing → finished product, be characterized in being the wood grain of material by veneer through contaminating different colours and angled sawing acquisition, for the seeds having veneer aberration, also need through bleaching before dyeing.Often there are the following problems for its dyeing course: 1, veneer need be contaminated in the dye pond of 85 ± 5 DEG C of temperature by dyeing process, and dip-dye process has a large amount of irritative gas to volatilize, and harm operator is healthy, and has a large amount of industrial wastewater to discharge, and causes environmental pollution; 2, fast growing wood has larger anisotropy, heart sapwood material aberration is greatly different, and heart sapwood moisture content is different, therefore in dyeing course, very easily occur that dyeing is uneven, and in drying steps after dyeing course, there is the distortion, the problems of crack that cause colored single palte because moisture content is uneven; 3, the process of dyeing process to timber only rests on surface, therefore existing Recombinant Wood veneer thickness is at about 0.7-0.8mm.
Summary of the invention
The object of the invention is to, a kind of production technology of new technology wood is provided.The product wood color that the present invention produces and moisture content evenly, and can expand veneer thickness, can also enhance productivity, and can avoid the environmental pollution that chemical reaction causes simultaneously.
Technical scheme of the present invention: a kind of production technology of new technology wood, it is characterized in that, the method comprises the steps:
A, make blank veneer by rotary-cut or slicing, and blank veneer is cut into required size, obtain A veneer;
B, A veneer is carried out the charing heat treatment of different carburizing temperature, obtain required wood color, obtain B veneer;
C, B veneer is carried out impregnation, mold pressing and flitch health process successively, obtain C flitch;
D, the sawing of C flitch is become required decorative pattern and size, obtain finished product.
In the production technology of aforesaid new technology wood, described A veneer thickness is 0.7-4mm.
In the production technology of aforesaid new technology wood, described step b is, A veneer is placed in carbonizing apparatus, rapid temperature increases and humidification, temperature is increased to 80-90 DEG C, humidity humidification to relative humidity is 70%-80%, keep 1-2h, then staged temperature-rising method is adopted, be warmed up to 125-240 DEG C by the speed of 20-25 DEG C/h and keep 2-4h, finally adopt jet atomization water method by below fast cooling to 100 in carbonizing apparatus DEG C, stop jet atomization water, Temperature fall obtains B veneer to kiln discharge during 40-60 DEG C.
In the production technology of aforesaid new technology wood, in described step c, the glue of impregnation is urea-formaldehyde resin adhesive, and solid content is 55%-60%, and 25 DEG C time, viscosity is 330-400mPas, ph value is 5-6.
In the production technology of aforesaid new technology wood, in described step c, the method for flitch health is, makes intermediate products flitch after B veneer is carried out impregnation and mold pressing, and by flitch room temperature health 4 days, obtains C flitch.
In the production technology of aforesaid new technology wood, described charing heat treatment is kiln formula charing heat treatment, hot pressing charing heat treatment and pot type charing heat treatment, or any combination mode of three's heat treatment mode.
Compared with prior art, the present invention is changed colour to timber by high temperature carbonization heat treatment, not only can improve wood dimensional stability and anti-corrosive durability, mode also by control treatment temperature, time and process makes timber obtain different wood colors, and make the wood color on the whole plate face of fast growing wood veneer, moisture content is tending towards uniformity.The present invention also tool has the following advantages: 1, veneer wood color and moisture content evenly, also eliminate the blanching step of part tree lumber, reduce processing step, cost-saving; 2, material internal pore permeability increases, and improves the operating efficiency of glue application step, and then enhances productivity further; 3, pure physical modification, avoids the environmental pollution that chemical treatment causes, and can reduce the harm to operator's health; 4, charing heat treatment is changed colour and can be run through the whole thickness of timber and length direction, and therefore can expand veneer thickness, the maximum veneer that makes expands 4mm to, is 5 times of the veneer that changes colour of routine.The present invention carries out impregnation by specific glue, and the effect that makes to change colour is better.
