Abstract
The invention relates to the technical field of lumber processing and an improved method of integrated solid lumber. The method comprises the steps of cutting the lumber into single boards with a thickness of 0.1 to 5mm, drying the single lumber board to have the average moisture content between 5 percent and 25 percent, dipping the dried single lumber board in chemical liquid till the single lumber board has fully absorbed the liquid, drying the dipped single lumber board, coating adhesives and then thermally pressing the single board into integrated solid lumber. By adopting the improved method of the invention, the dipping time and the dipping quality can be controlled more easily and the full dipping effect is easily available; meanwhile, after making the integrated lumber by thermally pressing, the inside of the lumber is treated completely as the outside, thus improving the quality of a finished product.
Description
Technical field
The present invention relates to a kind of wood processing technique field, particularly a kind of method of modifying of solid wood integrated material.
Background technology
In today of timber resources growing tension, how to effectively utilize as artificial timber that fast-growing woods produces such as poplar, pine, make it have range of application more widely, be the effective ways of alleviating the timber resources anxiety, also be the effective means of protection wildwood.For service life and the outdoor antiseptic property that improves timber, reach timber, the modification purpose of especially artificial timber that fast-growing woods produces, people blot the water and air in the timber only earlier with the method for negative pressure of vacuum usually, then the method for a kind of cotton wood post processing that provides as patent 02129646 is provided in the timber for anticorrosion, fire prevention or other improved chemicals.Adopt above-mentioned Wood treatment method, need to use vacuum equipment, processing cost is higher.
Summary of the invention
The purpose of this invention is to provide a kind of low-cost effective ways that can carry out the microcosmic processing to timber.For this reason, the present invention adopts following technical scheme:
A kind of method of modifying of solid wood integrated material, adopt following step:
(1) timber is cut into 0.1 to the veneer of 5mm;
(2) wood single-plate is carried out drying and handle, make its average moisture content between 1～25%;
(3) wood single-plate after will drying immerses to handle to soak in the soup and soaks into fully until soup;
(4) wood single-plate that has soaked into soup is dried processing;
(5) be raw material with treated veneer, coating binder is made solid wood integrated material through hot pressing again.
In the above-mentioned steps (1), preferably timber is cut into 0.2 to 3mm veneer; Soak time in the step (3) can be at 30 seconds between half an hour.
The present invention is cut into veneer to timber, handle through super-dry, the moisture content that makes veneer is 1～25%, again wood chip is placed on to soak in the soup to soak into fully to dry until soup after again drying being handled again and handles and integration process, adopt such method can improve wood characteristics, reach the purpose of anti-cracking and distortion.Can also handle with the soup that contains anticorrisive agent, fire retardant or aromatic, can also make have anticorrosion, prevent fires or have the solid wood integrated material of aromatic odor, this method technology is simple, need not adopt vacuum equipment, processing cost is very low; The present invention adopts Wooden veneer to flood, and has shortened the time of dipping, makes soup can soak into veneer fully.
The present invention makes veneer with timber earlier, and veneer is soaked.This method that veneer is handled makes the immersion treatment of the drying of wood and timber all realize than being easier to, and handles required time and shorten greatly, has also saved the energy, man-hour and consumption of raw materials simultaneously.For example the drying of veneer can adopt infra-red drying equipment to carry out continuous drying, can shorten the dry needed time, has improved dry quality, improves the efficient of producing.And the immersion treatment of soup can be soaked into to reaching fully between half an hour at 10 seconds usually.Processing method of the present invention is suitable for the processing to the loose fast-growing woods wood of material, if adopt method of the present invention to handle the hardwood material that is difficult to soak into, and should the proper extension infiltrating time.The present invention has improved the speed that soup soaks, and simplifies equipment and technology that soup is handled, makes simple to operateization, can realize at normal temperatures and pressures.
The present invention is carrying out before the soup dipping timber being cut into veneer, and the time of dipping and the easier control of the quality of dipping are easy to dipping and reach effect completely; And after integrated sheet was made in hot pressing, the inside of sheet material also was to handle fully, and the effect of processing is thought and acted in one and the same way, and had improved the quality of finished product.
The specific embodiment
Embodiment:
The timber chipless process technology that adopts is cut into veneer to timber, and veneer is dried processing, makes its average moisture content 1～25%; Then the wood chip after the dry processing of drying is placed in the soup and soaks; Soak more than 30 seconds, soup is soaked into fully dry processing again; Adopt the pressurization technology that wood chip is pressed into glued board.
The preparation of raw material veneer
Adopt the chipless saw lumber method of rotary-cut or slicing, the quick-growing plantation log is processed into the veneer of thickness at 0.1～5mm, be preferably between 0.2 to 3mm.Veneer is carried out drying handle, the equilibrium moisture content that makes veneer is 1～25%.Veneer is screened, shears and repair, remove have in the veneer go mouldy, the place of worm channel, rotten, defective such as scab, and repair with the veneer of high-quality, the veneer after the repairing is cut into certain specification.
1, impregnation process
The raw material veneer for preparing is further processed, adopts the method for normal pressure dipping to handle; This road technology mainly is timber to be carried out modification handle, and makes it satisfy specific instructions for use.Wooden veneer is immersed in medicament is penetrated in the Wooden veneer, different according to the thickness of veneer with employed medicament, determine to soak the needed time, generally at 30 seconds between half an hour.The method operating equipment is simple, and the equipment input cost is low.Owing to adopt veneer to handle, shortened the time of soaking, the medicament section time just can be permeated fully, improved the quality of dipping, improved to produce and renderd a service, also saved the energy and consumption of raw materials in the chemicals treatment process simultaneously.
2, assembly hot pressing
Veneer through immersion treatment is carried out drying handle, make its moisture content reach the humidity requirement of cloth glue, carry out veneer cloth glue, carrying out the veneer assembly according to grain direction; Last hot pressing is made and is had the specific use solid wood integrated material.
Claims (3)
1. the method for modifying of a solid wood integrated material is characterized in that adopting following step:
(1) timber is cut into 0.1 to the veneer of 5mm;
(2) wood single-plate is carried out drying and handle, make its average moisture content between 1～25%;
(3) wood single-plate after will drying immerses to handle to soak in the soup and soaks into fully until soup;
(4) wood single-plate that has soaked into soup is dried processing;
(5) be raw material with treated veneer, coating binder is made solid wood integrated material through hot pressing again.
2. the method for modifying of solid wood integrated material according to claim 1 is characterized in that in the step (1), timber is cut into 0.2 to 3mm veneer.
3. according to the method for modifying of claim 1 or 2 any described solid wood integrated materials, it is characterized in that, the soak time in the step (3) at 30 seconds between half an hour.
