1 on demand door-plate, bed board, furniture made earlier corresponding thin plate, wood fragments thin slice, isometric corncob section respectively with the thickness and the specification requirement of length and width size of plate on different equipment.
2 in the corresponding interval joint of composite plate coated with adhesive.
3 on equipment the pressurization heating, temperature keeping suppress.
Deburring (side cut, coating adhesive, trimming strip) is carried out on the 4 pairs of composite plate that has suppressed four limits
5 on equipment two outer faces to the composite plate that suppressed carry out sanding.
Embodiment during the present invention incites somebody to action in conjunction with the accompanying drawings is described in further detail:
Fig. 1 is the vertical section schematic diagram of cob sandwich board.
Fig. 2 is the schematic cross section of cob sandwich board.
Sequence number zero in the accompanying drawing, parts illustrates:
1, gap between thin plate 2, adhesive 3, wood fragments thin slice 4, adhesive 5, thin plate 6, adhesive 7, corncob 8, corncob central part 9, adhesive 10, upper and lower plates.
Cob sandwich board is a kind of composite plate, the both ends of the surface of this composite plate are thin plate 1,5, wood fragments thin slice 3 and the tabular composition that is bonded together with adhesive (Lauxite), intermediate course is a corncob 7, between the tabular composition at the both ends of the surface of isometric corncob section and two ends is vertical, and corncob 7 is intensive putting, and is bonded together with adhesive.Concrete manufacture method is:
(1) door-plate on demand, bed board, the furniture thickness and the specification requirement of length and width size of plate, on rotary lathe equipment, make corresponding thin plate 1,5 earlier, wood fragments thin slice 3, on the equidistant milling cutter equipment of vertical or horizontal multi-disc, milling becomes isometric corncob section.
(2) in the equivalent layer of composite plate, section joint coated with adhesive, be to stick wood fragments thin slice 3 after thin plate 1 coated with adhesive 2 between the plate face, coated with adhesive 4 again, stick thin plate 5, coated with adhesive 6 again, found the perpendicular intensive corncob 7 of laying out, and do the tabular composition of the other end well with method, on the face of this tabular composition after the coated with adhesive 9, linking to each other with the other end of upright perpendicular corncob 7 is bonded together.
(3) energising was pressurizeed 3 hours on the equipment that is provided with middle temperature (60 ℃-70 ℃).
(4) the composite plate four side that has suppressed is carried out deburring (side cut, coating adhesive, veneer edge strip).
(5) sanding is carried out in two outer faces to the composite plate that suppressed on equipment.
The method of above-mentioned coating adhesive (Lauxite) can be coated with method by the employing machine, also can adopt the manual method that is coated with.
The intermediate course of this composite plate, there is the space, centre coarse because of the surfaces externally and internally of upright perpendicular corncob 7, forms this composite plate and compares with other plank of uniform thickness, and it is little to have elasticity, sound insulation, thermal conductivity factor.Find out that from accompanying drawing 1 it is Bao Deduo that the layer of wood of this composite plate (tabular composition) thickness is compared with the thickness of corn sandwich layer.In the thick composite plate of 2cm, layer of wood accounts for 20% of composite plate thickness, and the corn sandwich layer accounts for 80%; In the composite plate of 4cm, layer of wood accounts for 15.4% of composite plate thickness, and the corn sandwich layer accounts for 84.6% of composite plate thickness.Same length physical dimension on weight, the weight of cob sandwich board is 50% of particieboard weight, opening the large clothes closet furniture with common three is example: with three-ply board, rib producing wood, fee of material needs 150 yuan, need 30 yuan when artificial, expense is 1: 5 with the ratio of fee of material when artificial; If make of cob sandwich board, fee of material needs 50 yuan, needs 10 yuan when artificial, and expense is 1: 5 with the ratio of fee of material when artificial.Corresponding comparing, same workman makes same big common three and opens large clothes closet, need 150+30=180(unit with three-ply board, rib producing wood), and need 50+10=60(unit with the cob sandwich board making), just the former expense is three times of latter's expense, is the latter's three times when artificial when the former is artificial.
When making door-plate with the corn filled board, at the stitching page or leaf place of door-plate, last built-in lock place should adopt certain thickness little plank or lath, and the thickness of corncob section should be higher than little plank or lath thickness 1-1.5mm, to guarantee that this composite plate is heated, pressurizeing forms.Still use adhesive together bonding between the tabular composition of this little plank or lath and upper and lower end face.
The corncob water content that is adopted in the corn folder filled board is 8-12%, the 20 yuan/m of price of corncob
3, the 700 yuan/m of price of cob sandwich board
3The bed board made from cob sandwich board: long * wide * thick be 2000 * 700 * 39, two end supports, the people of 80kg body weight stands in the middle of the door-plate, bed board slightly is out of shape, after the people leaves, bed board restore to the original state (bed board is flexible).
