Description
Technical field
The invention belongs to plank processing technique field, relate to a kind of core-board processing technology of low aldehyde.
Background technology
Core-board holds that screw power is good, and intensity is high, have the features such as matter heavily fortified point, sound absorption, thermal insulation, and moisture content is not high, between 10%-13%, processes easyly, and purposes is the most extensive.With the comparison of solid wood jigsaw, core-board dimensionally stable, not yielding, effectively overcome anisotropy of wood, there is higher transverse strength, owing to strictly observing symmetrical assembly principle, effectively avoided the buckling deformation of sheet material.Laminated wood board face is attractive in appearance, and breadth is roomy, easy to use, is mainly used in Furniture manufacture, door-plate, wallboard etc.
Traditional core-board is formed by the plank of glue laminated splicing in the middle of two veneers, because the plank side splicing directly docks, directly gluing is hot-forming, and horizontal central layer is difficult for guaranteeing consistency of thickness, thereby affects gluing effect, while sanding flat in sanding operation, the sand amount of cutting increases, can increase difficulty of processing, cause the lateral stressed inequality of central layer seam crossing simultaneously, easily come unglued, to such an extent as to finished product buckling deformation affects product quality; Again in the gluing formula due to plate joggling apparatus splicing and assembly matching board, adopt containing the higher adhesive of aldehyde, in process, do not fall again aldehyde and process, cause finished product free formaldehyde release too high, in finishing or making furniture, used after this type of material, will produce greatly harm to health.
In the prior art, for reducing the harm of formaldehyde, have some national standards to require environment friendly lumbercore plywood must use environment-friendly type adhesive, but compare with traditional adhesive, its bonding strength is relatively poor, and production cost is also higher, is therefore difficult to be widelyd popularize.

In figure: 1-lath, 2-blind mortise, 3-tenon.
The specific embodiment
Below in conjunction with accompanying drawing, further describe technical scheme of the present invention, but described in claimed scope is not limited to.
As shown in Figure 1 and Figure 2, the core-board processing technology of a kind of low aldehyde of the present invention, comprises that aldehyde step falls in central layer splicing, middle plate veneer, dash board veneer and deburring, and concrete steps are as follows:
1) central layer splicing
A. log prescinds
B. open bar: with stripping-cutting machine, the log of segment is cut into lath 1;
C. dry: lath 1 is placed in to steam drying room and dries, control lath water content 12%～15%;
D. S4S: carry out surely thick two-sided processing by four-side planing, guarantee lath 1 consistency of thickness;
E. longitudinal mortise: longitudinally open blind mortise 2, one sides along lath side one side and longitudinally process corresponding tenon 3, the falcon degree of depth of longitudinally opening blind mortise 2 is less than width, and tenon 3 sizes are mated with blind mortise 2, and tenon 3 is highly less than recessed falcon 2 degree of depth; The mortise degree of depth is more shallow, is easy to processing, and very little on the stressing conditions impact of a falcon joint, and the adhesive coverage rate of lath stitching portion is increased, and has promoted the reliability of gluing together between lath, thereby has strengthened the longitudinal strength of finished product;
F. a gluing: because lath splicing is the important leverage of core-board transverse strength, and the bonding strength of novel environment friendly aldehyde-free adhesive is relatively poor, therefore still adopt traditional adhesive to carry out artificial gluing to lath both sides;
G. arrange plate: by the recessed falcon 2 of lath and a falcon 3 corresponding splicing respectively;
H. side pressure jigsaw: the lath of having spelled is sent in side compression machine, be spliced into entire plate core under 100～120 ℃ of conditions;
I. normal temperature self-drying: the plate core of moulding is placed more than 24 hours under normal temperature condition, made it cooling, adhesive solidifies simultaneously;
2) plate veneer in
A. second glue spreading: adopt and be uniformly coated on plate core two sides without aldehyde glue, in traditional adhesive that gluing is adopted is completely enclosed within; Meanwhile, the novel bonding capacity without aldehyde glue can meet the middle required bonding strength of plate veneer completely;
B. plate in pasting: middle plate is fitted with plate core two sides respectively;
C. a hot pressing: the slab after plate in laminating is placed in to hot press, precompressed 50min, after under 100 ℃～120 ℃ conditions hot pressing 10min;
D. naturally cooling: the slab after hot pressing is placed 10～12 hours under normal temperature condition, made it naturally cooling, adhesive solidifies simultaneously;
