The secondary core-board of a kind of low-carbon (LC) and manufacture method thereof
Technical field
The wood-based plate manufacturing technology field that the invention belongs to wood working industry, relates to the secondary core-board of a kind of low-carbon (LC) and manufacture method thereof.
Background technology
Along with the raising of China's economic level and people's living standard, market increases day by day to the demand of wood-based panel product.At present, China has become world's Wood-based Panel Production and consumption the first big country, according to statistics in 2011, shows: China's year produce wood-based plate ability and reached 20919.29 ten thousand steres, occupy the first in the world.The development of wood-based panel industry is conducive to alleviate China's timber imbalance between supply and demand, saves timber resources.But in building board production process, can produce a large amount of cutting edge material, according to measuring and calculating, the cutting edge material producing in building board production process accounts for 7.4% of total amount.About the disposal of cutting edge material, artificial board enterprise is mainly taked following two kinds of ways at present: the one, cutting edge material is burnt as boiler oil; The 2nd, sanction edge recycling is pulverized to decomposition, as fiberboard or particieboard raw material, re-use (regeneration).The first processing method is treated as waste disposal by cutting edge material completely, utilizes effect the poorest, and the energy and raw material resources waste are maximum.Although the second processing method is carried out reclaiming utilization by cutting edge material, the rim charge that must cut into two exact halves " melts down " decomposition, hot pressing again, has not only increased secondary energy consumption, and what obtain is low value product, so each side benefit is all undesirable.If cutting edge material is used in secondary mode (cutting edge material need not melt down reprocessing and directly as other raw material of artifical plate), by the energy with extremely low and resource consumption (low-carbon (LC)), obtain high-quality wood-based plate new product, meet low-carbon economy requirement, will benefit the nation and the people.The present invention is exactly based on above-mentioned theory, by online preparation method, wood-based plate cutting edge material is made to thin fillet, then as high quality artificial board raw material, be used, reach and simplify technique, turn waste into wealth, low-carbon energy-saving, minimizing resource consumption, improve the object of society and economic benefit.
Core-board is a kind of in wood-based plate, be widely used in the industries such as furniture, decoration, construction and decoration, at present core-board used is consisted of upper and lower two-layer veneer and the plate core that is clipped between veneer, plate core is mainly that to take the timber such as the more loose China fir of material, poplar be raw material, with multiple blade saw, first log is sawn into certain thickness not wide sheet material, then sheet material is split into certain thickness, width thin fillet not etc. with band saw or multiple blade saw, by thin fillet, in width top rail, to misconnection, is put together.The core-board that adopts this technique to manufacture is more complicated, and cost is higher, consume a large amount of timber, produces a large amount of leftover pieces in production process, and is difficult to make common core-board realize the functions such as fire prevention, protection against the tide from technique, and therefore functional poor, class is lower.
Summary of the invention
The object of the present invention is to provide that a kind of manufacturing process is simple, processing cost is low, the secondary core-board of the low-carbon (LC) of low-carbon environment-friendly and manufacture method thereof.
To achieve these goals, the present invention has adopted following technical scheme:
A secondary core-board, is mainly comprised of plate core and upper and lower cover plate; Wherein, described plate core is mainly spliced by take thin side's bar that the cutting edge material of wood-based plate makes as raw material, and on the plate face having spliced, adopts gummed paper bar to paste the fixing thin side's bar having spliced with " N " font.
The mode of above-described thin side's bar splicing is dislocation splicing.
The cutting edge material of above-described wood-based plate is the cutting edge material of general fibre plate or glued board or particieboard or flame retardant fibre board or anti-wet fiber plate.
Above-described cover plate is common face crossing or dipping veneer or melamine decorative veneer.Cover plate can be selected according to product requirement.
A method of manufacturing the secondary core-board of above-mentioned low-carbon (LC), comprises the following steps successively:
(1) preparation of thin side's bar
In the outside parallel connection of the former cutting edge saw blade of the longitudinal and transverse edge cutting machine of artificial board product line, add and load onto scoring blade, saw, except loose burr on cutting edge material, obtains homogeneous, specification is certain thin side's bar;
(2) plate core is assembled
Thin side's bar in step (1) is spliced into side by side to the plate core of required specification, and in splicing, the piece between thin side's bar two row is gluing not, only on the plate face having spliced, adopt gummed paper bar to paste with " N " font fixing;
(3) assembly of mating formation
Cover plate in the Ban Xin above and below of splicing and fixing coated with single spreading, obtains slab;
(4) precompressed
The slab combining is placed on cold press and carries out precompressed, slab is tentatively formalized;
(5) hot pressing
Slab after precompressed setting is sent in hot press, carried out hot pressing, obtain finished product hair plates;
(6) cutting edge
Hair plates is carried out to cutting edge, obtain dimension board;
(7) sanding and facing are processed
Dimension board is carried out to two-sided sanding, then with veneer or finishing paper, carry out incrustation processing; If upper and lower cover plate adopts melamine decorative veneer, without carrying out incrustation processing;
(8) check and finished product warehouse-in
The secondary core-board obtaining through step (7) processing is checked and finished product warehouse-in according to a conventional method.
Advantage of the present invention:
1. manufacturing process is simple, processing cost is low, energy-saving low-carbon environmental protection.The plate core of secondary core-board of the present invention derives from the cutting edge material of wood-based plate, is accompanied by building board production process and automatically generates, and processing and manufacturing specially, has realized waste material and directly utilized.The preparation of thin side's bar is directly on artificial board product line, to complete, and has saved special thin side's bar production process, the production technology of secondary core-board of the present invention is greatly simplified, so energy-saving low-carbon cost is low.
2. have the succession to wood-based plate (motherboard) function, combination property is more superior.The plate core of secondary core-board of the present invention derives from the cutting edge material of wood-based plate, and the physical and mechanical property of wood-based plate etc. are all obviously better than the former green woods such as China fir, poplar, makes to use class, the performance of the core-board that wood-based plate cutting edge material manufactures higher; In addition, because be the cutting edge material that directly uses wood-based plate, so this secondary core-board can be inherited original function (as the function such as fire-retardant, moistureproof) of cutting edge material motherboard completely, this has also simplified the work flow that need to possess the secondary core-board of corresponding function greatly, reduce processing cost, there is good economic benefit.
3. save gluing consumptive material, environmental protection, cost are low.In the present invention, plate core is when adopting thin side's bar to splice, do not adopt gluing barbola work on thin side's bar piece face, and adopted, after splicing well, thin side's bar with gummed paper bar, with " N " font, pastes fixing mode on plate face, so not only can fix thin side's bar, and saved a large amount of glue, and reduced burst size of methanal, there is good social benefit.
