Description
Technical field
The present invention relates to the preparation method of a kind of timber square stock, the manufacture method of the directed laminated veneer lumber square bar of especially a kind of xylon.
Background technology
China's Forest Resources is poor, and wood supply is nervous, therefore, utilizes discarded timber resources to seem particularly important. Laminated veneer lumber material is with the thick veneer of rotary-cut, through applying glue, rift grain assembly, exerts pressure gummed and a kind of type material of obtaining, it is possible to as structural lumber, it is also possible to as upholstery materials such as furniture. But the time that laminated veneer lumber material is introduced to the market at present is not long, output is still very little, wherein very big reason is that its thickness of laminated veneer lumber material manufactured due to existing technological method is less, generally it is difficult to more than 30mm, owing to adopting existing hot-pressing technique heat transfer process too slow, production efficiency is low, during compacting heavy thickness sheet material, the phenomenons such as core layer cracking easily occurs, and sheet material bonding strength is inadequate.
" a kind of method of making non-formaldehyde laminated veneer lumber from gum wood " disclose a kind of manufacture method without aldehyde laminated veneer lumber material, by eucalyptus veneer is carried out soften handled, substantially the inherent strain of eucalyptus veneer is released, simultaneously by scientific and reasonable assemble pattern, solve, with eucalyptus wood making laminated veneer lumber material, buckling deformation problem easily occurs, and tackiness agent adopts the timber composite modified starch tackiness agent of formaldehydeless base, make the eucalyptus formaldehydeless release of veneer cord-wood, become environmentally friendly product. " quick growing species of trees laminated veneer lumber material manufacture method " of CN102615681 discloses a kind of laminated veneer lumber material manufacture method adopting high-temperature hot solidification manufacturing process in preheating in coldmoulding, kiln, kiln.
Existing method has three drawbacks, its one, the higher meeting of actual pavement material exceedes the height of mould, do not adopt precompressed be difficult to realize, its two, hot setting in the kiln of employing, it it not continous way, inside disposable airtight kiln, substantially belong to cold enter cold go out, efficiency is low, they are three years old, the solidification value of kiln is different, is generally 70-100 DEG C, time longer easy generation catabiosis.
Summary of the invention
Technical problem to be solved by this invention is to provide the directed laminated veneer lumber square bar manufacture method of a kind of xylon.
Solving the problems of the technologies described above the technical scheme adopted is:
The directed laminated veneer lumber square bar manufacture method of this xylon carries out as follows:
(1) preparation of raw material veneer: after fast growing wood log boiling is softening, rotary-cut machine is peeled into log veneer, or collect the discarded veneer of plywood making generation, cut the veneer of growth (600-2500) mm �� wide (100-300) mm �� thick (1.5-3) mm specification again, free of bark, not mouldy, surface is polluted without resin canal and oiliness, water ratio��10%;
(2) raw material veneer glue application and ageing; With Phenol aldehyde resin or urea-formaldehyde resin adhesive or cyanurotriamide modified Resin adhesive, adopting impregnation or roll coating model gluing, the impregnation time is 10-20min, and resin added is 5-15%, and digestion time is 1��5h;
(3) oven dry of applying glue veneer; Employing net belt type is dried, and heat-transfer medium temperature is 40-60 DEG C, and oven dry to impregnation Veneer moisture is 10%-25%;
(4) veneer health: will applying glue veneer dry after put into warehouse or balance room, temperature within 10-50 DEG C, health 2-7 days;
(5) veneer orientation is mated formation; Design specification according to laminated veneer lumber square bar and density, quantitatively take veneer, by veneer longitudinally along the grain direction, parallel layer by layer stacks in feeder equipment, and the raw material paved is pushed in chilling press by feeder equipment, builds cover plate on material;
(6) square stock mold pressing; Chilling press is by, in material press-in die, the inside dimension of mould is long (600-2500) mm �� wide (100-300) mm �� height (100-300) mm; Pressing cycle: 1��3min, progressive die two ends are struck together smooth, after pressure head is pressed onto position, tommy is squeezed into the locking cover plate of the locking hole on mould, mould is pulled out chilling press, is pinned by mould with screw rod;
(7) square stock solidification; The long 40-60 rice in solidification tunnel, tunnel divides four curing area, 1 temperature 100-120 DEG C, district, 2 temperature 115-130 DEG C, districts, 3 temperature 120-135 DEG C, districts, slowly advances in 4 temperature 110-125 DEG C, districts, total time 8-13h; Curing process adopts continous way charging and discharge method;
(8) the square stock demoulding: mould, after being cooled to 40 �� 2 DEG C, dismantles pin and bolt, the mold demoulding;
(9) square stock tack: cut flush end head by equal for sawing amount in square stock two ends;
(10) square stock health: be stacked in natural ventilation place, conditioned time by smooth for square stock: 7 days winters, 15 days summers;
(11) aftertreatment: fixed thick, fixed wide, cut out cut, quality inspection, packaging.
The invention has the beneficial effects as follows: mould is placed in chilling press that quantitative feeding the method that paves are pressed in mould with cold-press process, dry with continous way tunnel, heat enter cold go out, efficiency height, the solidification value of kiln is 100-130 DEG C, glue-line stable performance, it is not easy to produce catabiosis.
Adopt present method, raw material sources are wide, discarded veneer can be utilized, save cost, efficiently solve the problem manufacturing the big laminated veneer lumber material difficulty of thickness, plate surface and core layer curable adhesive layer are even, square bar stable performance and be better than solid wood hardwood, can replace solid wood hardwood completely, and manufacturing process is simple, production efficiency height, is applicable to suitability for industrialized production.
