Description
Technical field
The present invention relates to wood-based plate manufacturing technology field, particularly relate to a kind of core-board utilizing artificial bladed saw rim charge to recombinate and production method thereof.
Background technology
At present, the available timber resources of China is limited, and timber supply and demand contradiction is the most prominent.Artificial board enterprise is relatively low to the utilization rate of timber, especially the sheet material enterprise such as plywood, finger-jointed plate and core-board, and its corner saw material, mostly as fuel or garbage, fails to be used adequately reasonably.
Summary of the invention
The purpose of the present invention is that the shortcoming and defect overcoming prior art to exist, it is provided that a kind of core-board utilizing artificial bladed saw rim charge to recombinate and production method thereof.
The object of the present invention is achieved like this:
The saw rim charge of the wood-based plate finished product such as (plywood, finger-jointed plate and core-board sheet material) or semi-finished product is reconfigured and structure design, by techniques such as assembly, precompressed and hot pressing, produce the core-board of a kind of new construction, timber utilization rate 3～4% can be improved, available surface quality and the restructuring core-board product of excellent in mechanical performance while economizing on resources.
The technical solution adopted for the present invention to solve the technical problems:
One, the core-board (being called for short the core-board of restructuring) that artificial bladed saw rim charge is recombinated is utilized
The core-board of this restructuring includes sheet surface layer, the 1st middle layer plate, element central layer, the 2nd middle layer plate, bottom plate, laterally saw trimmings and longitudinally saws trimmings；
Its annexation is:
From top to bottom, sheet surface layer, the 1st middle layer plate, element central layer, the 2nd middle layer plate and bottom plate are sequentially connected with；
Described plain central layer is combined with longitudinally saw trimmings by laterally sawing trimmings.
Two, the production method (abbreviation method) of the core-board that artificial bladed saw rim charge recombinates is utilized
This method comprises the following steps:
1., after impregnation, by the 1st middle layer plate lower surface and the 2nd middle layer plate upper surface through glue spreader cloth glue, two-sided cloth glue amount is 300～350g/；
2. recombinate on the glue-line of the 2nd middle layer plate, mat formation and laterally saw trimmings (6) and longitudinally saw trimmings (7) as element central layer, wherein, the width of edge strip is the width of element central layer, and the trimmings number of combinations in direction in length and breadth is than for 2:1, and alternately arranged, the plain central layer completing required breadth is mated formation.After having mated formation, the 1st central layer rubberised layer is covered on element central layer, make element central layer be fixed in the middle of the 1st middle layer plate and the 2nd middle layer plate.1st, plywood assembly symmetry principle followed by 2 middle layer plates and element central layer assembly, forms three-ply board after assembly；
3., after three-ply board assembly completes, pre-pressing stage, pressure 0.5～1.0MPa, time 1.0～1.5 hours are entered；
4. through surface-defect repairing after three-ply board precompressed, hot press period, temperature 105～110 DEG C, pressure 1.0～1.5MPa, time 8～10 minutes are entered；
The most then carry out Puttying filling-in, sanding, three-ply board upper and lower surface gluing and form five-layer plywood with table, bottom plate assembly；
It is the most finally five-layer plywood base hot pressing, temperature 105 DEG C～110 DEG C, pressure 1.0～1.2MPa, time 3～5 minutes, through saw sand, check qualified, be the core-board of restructuring.
Compared with prior art, the present invention has following advantages and a good effect:
1. make full use of a large amount of discarded corner saw material that the processing such as plywood, finger-jointed plate, core-board and solid wood furniture sheet material produce, timber utilization rate 3%-4% can be improved；
2. owing to the thickness specification of edge strip is unified and its internal stress of rim charge after secondary operations greatly reduces, after restructuring, surface quality and the flatness of sheet material are good, its percent ripple≤0.3mm, angularity≤0.2% after sanding；
3. the cost of product is relatively low, about the 50% of the most common core-board.
