Abstract
The invention discloses a method for improving strength and eradicating crack of soft wooden material. According to the technical scheme, the method is performed according to the following steps that first, veneer of the soft wooden material is removed, and the soft wooden material is machined into blank material as required; second, the blank material is dried till the water content is between 8 percent to 12 percent; third, the dried blank material is subjected to high-temperature heat treatment; fourth, the blank material subjected to high-temperature heat treatment is soaked into hot glue or smeared with hot glue so that the hot glue can fully permeate into the blank material; fifth, the blank material into which the hot glue permeates is compressed into the required shapes in a hot-pressing mode or an extruding mode and then formed through cooling. The method has the advantages that the strength of the soft wooden material can be improved, crack of the soft wooden material can be eradicated, the utilization value of the soft wooden material is expanded definitely, and waste of wood resources is reduced.
Description
Technical field
What the present invention relates to is a kind of method of improving soft wood materials, a kind of specifically method that improves soft wood material strength, stops cracking.
Background technology
Soft timber (for example: Eucalyptus, poplar, the pine) speed of growth, than very fast, generally can be become a useful person in 5-10; And being 30-50 substantially, hard wood just can become a useful person.Soft timber is because the material of timber own is soft, be merely able to manufacture the timber products very low to requirement of strength, and the flexibility of these low-intensity timber products, cracking never have processing method cheaply, make loose subereous Available Material cannot improve value, cause the significant wastage of timber resources.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and can improve soft wood material strength, stop the method for cracking, limitedly expand loose subereous value, reduce the waste of timber resources.
The present invention improves soft wood material strength, stops the method for cracking, carries out according to the following step:
(1) soft timber is removed to wooden skin, be processed on demand blank material;
(2) by dry blank material process to moisture content be 8%～12%;
(3) will be dried blank material high-temperature heat treatment after treatment;
(4) make hot glue water fully permeate blank material in the mode of soaking or smear the blank material after high-temperature heat treatment;
(5) will infiltrate the blank material of hot glue water, blank material will be compressed to cooling forming after the shape needing in the mode of hot pressing or extruding.
The beneficial effect that the present invention improves soft wood material strength, stop the method for cracking is: can improve soft wood material strength, stop cracking, limitedly expand loose subereous value, reduce the waste of timber resources.
The specific embodiment
Below in conjunction with embodiment, the present invention is described in further detail.
The first embodiment:
(1) the soft timber such as Eucalyptus or poplar or pine are removed to wooden skin, be processed on demand bar-shaped blank material;
(2) by dry bar-shaped blank material process to moisture content be 8%～12%;
(3) will be dried bar-shaped blank material high-temperature heat treatment after treatment;
(4) the bar-shaped blank material after high-temperature heat treatment is immersed in the pressurized tank with glue, in pressurized tank, heats pressurization, make hot glue water fully permeate bar-shaped blank material;
(5) will infiltrate the bar-shaped blank material of hot glue water, bar-shaped blank material will be compressed to cooling forming after the shape needing in the mode of hot pressing.
The second embodiment:
(1) the soft timber such as Eucalyptus or poplar or pine are removed to wooden skin, be processed on demand plate-like blank material;
(2) by dry plate-like blank material process to moisture content be 8%～12%;
(3) will be dried plate-like blank material high-temperature heat treatment after treatment;
(4) the plate-like blank material after high-temperature heat treatment is immersed in hot glue water, makes hot glue water fully permeate plate-like blank material;
(5) will infiltrate the plate-like blank material of hot glue water, plate-like blank material will be compressed to cooling forming after the shape needing in the mode of pushing.
The 3rd embodiment:
(1) the soft timber such as Eucalyptus or poplar or pine are removed to wooden skin, be processed on demand plate-like blank material;
(2) by dry plate-like blank material process to moisture content be 8%～12%;
(3) will be dried plate-like blank material high-temperature heat treatment after treatment;
(4) the plate-like blank material after high-temperature heat treatment is smeared to hot glue water, make hot glue water fully permeate plate-like blank material;
(5) will infiltrate the plate-like blank material of hot glue water, plate-like blank material will be compressed to cooling forming after the shape needing in the mode of hot pressing.
Certainly, the embodiment that the present invention improves soft wood material strength, stop the method for cracking is varied, too numerous to mention.Every employing method of the present invention improves soft wood material strength, and the problem that has solved cracking all belongs to the scope of protection of the invention.
Claims (1)
