Description
Technical field
The invention belongs to stoving process field, especially a kind of drying and processing method of toothed oak wood.
Background technology
Solid wood furniture has the features such as natural, environmental protection, health, log look furniture not only natural, but also without chemical contamination, be not only the preferably selection of modern healthy life, also meet the psychological needs that people from modern metropolitan cities advocates the Nature.In addition, solid wood furniture, in the process of processing and fabricating, is compared with the furniture of those wood-based plates, and glue consumption is quite few.Glue consumption number affect furniture the feature of environmental protection height.But the topmost shortcoming of solid wood furniture is exactly yielding, and maintenance is got up more difficult, such as can not allow sunlight direct irradiation, and it is cold overheated to cross, and too dry and moist environment is all not suitable for solid wood furniture; If do not noted in use, it is excessive that frequent switch air-conditioning causes humiture to change, and thus, the timber stoving step before solid wood furniture machine-shaping seems particularly important.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of drying and processing method accelerating to eliminate the inherent strain of timber and the toothed oak wood of wood is provided.
The present invention solves its technical problem and takes following technical scheme to realize:
A drying and processing method for toothed oak wood, is characterized in that: its baking step is:
(1) first drying process: by the air-dry buttress of toothed oak wood wet plate code in drying kiln, close moistureproof window, kiln temperature is increased to 65 DEG C, and kiln humidity remains on 62% ~ 64%, after 3 hours, regulate kiln temperature to 55 DEG C, kiln humidity remains on more than 45%, after 2 hours, open moistureproof window, regulate below kiln humidity to 48%, remain on 30 ~ 50 hours under room temperature, carry out secondary drying process;
(2) secondary drying process: close moistureproof window, kiln temperature is increased to 65 DEG C, kiln humidity remains on 62% ~ 64%, after 5 hours, regulates kiln temperature to 58 DEG C, kiln humidity remains on more than 45%, after 2 hours, open moistureproof window, regulate below kiln humidity to 48%, remain on 50 hours under room temperature, carry out three drying and processings;
(3) three drying and processings: close moistureproof window, kiln temperature is increased to 65 DEG C, kiln humidity remains on 62% ~ 64%, after 5 hours, regulates kiln temperature to 60 DEG C, kiln humidity remains on more than 45%, after 2 hours, open moistureproof window, regulate below kiln humidity to 48%, remain on 50 ~ 70 hours under room temperature, carry out four drying and processings;
(4) four drying and processings: close moistureproof window, kiln temperature is increased to 65 DEG C, kiln humidity remains on 62% ~ 64%, after 5 hours, regulate kiln temperature to 63 DEG C, kiln humidity remains on more than 43%, after 2 hours, opens moistureproof window, regulate below kiln humidity to 45%, remain on 30 ~ 40 hours under room temperature, maintenance 24 hours, the mensuration of carrying out timber water content carried out final drying and processing;
(5) final drying and processing: close moistureproof window, kiln temperature is reduced to 0 DEG C, kiln humidity remains on 54% ~ 56%, after 3 hours, kiln temperature remains on 0 DEG C, and kiln humidity is adjusted to 0%, after 2 hours, open moistureproof window, kiln temperature remains on 0 DEG C, and kiln humidity remains on 0%, stops kiln, thus accelerate inherent strain and the wood of eliminating timber, reach the standard making furniture;
(6) health: after stopping kiln, at room temperature keeps 2 days by timber, ensures the not redeformation after making furniture thus.
And described toothed oak wooden one-tenth polylith length is 2000mm---4000mm, width is 60mm, thickness is the wet plate of 25mm.
And the air-dry buttress of described toothed oak wood timber is place 24 layers of birch plank in kiln, keeps certain gap between sheet material adjacent in drying kiln, is conducive to furnace air circulation, accelerates hydrofuge.
Advantage of the present invention and good effect are:
1, the oven dry plank water content obtained by furnace drying method provided by the present invention is only 8% ~ 10%, and timber inherent strain is minimum, its long service life, moisture resistance, not yielding, can reach more than 5 times of common plate fitment.
2, the furnace drying method that the present invention adopts is through about 240 hours steam dryings, is adding wet process through four times and is progressively improving temperature, accelerates the inherent strain and the wood that eliminate timber thus, thus reaches the high standard making furniture.
Wet plate is pressed the air-dry buttress of its equal length code (every part 24 layers) by the furnace drying method that 3, the present invention adopts, and is conducive to furnace air circulation, accelerates hydrofuge.
4, the present invention carries out the constant temperature health of 48 hours to timber after repeatedly humidification heat treatment, ensures the not redeformation after making furniture.
Detailed description of the invention
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
Drying kiln involved in the present invention is equipped with moistureproof window, by the humidity in the adjustable drying kiln of the open and close of this moistureproof window.
Wooden for toothed oak one-tenth polylith length is 2000mm---4000mm by a drying and processing method for toothed oak wood, width is 60mm, thickness is the wet plate of 25mm, and its baking step is:
(1) first drying process: by the air-dry buttress of toothed oak wood wet plate code in drying kiln, close moistureproof window, kiln temperature is increased to 65 DEG C, and kiln humidity remains on 62% ~ 64%, after 3 hours, regulate kiln temperature to 55 DEG C, kiln humidity remains on more than 45%, after 2 hours, open moistureproof window, regulate below kiln humidity to 48%, remain on 30 ~ 50 hours under room temperature, carry out secondary drying process;
