Described construction formwork, wherein the top layer of veneer grain direction and the oriented structure chipboard direction of mating formation is perpendicular or parallel, and the ply numerical control is built in the 1-2 layer, and keeps direction to intersect when the veneer number of plies is 2 layers between the adjacent ply.
Oriented structure chipboard imitation veneer generally is 3-tier architecture, and the direction of mating formation of two-layer wood shavings is parallel with the length direction of plate up and down, and the direction of mating formation of intermediate layer wood shavings is vertical, and this model just is not easy to deform.Because the wood shavings that oriented structure chipboard adopts are the strip wood shavings, therefore, the so-called top layer direction that direction promptly parallels with the long limit of strip wood shavings in the surface structure of mating formation.In addition, because veneer also is that grain direction (that is: the direction of growth of cell orientation or tree) is arranged, in veneer, just there is veneer grain direction and directional structure board the top layer consistent or vertical problem of direction of mating formation, but adopts direction between the adjacent layer to intersect the anti-bending strength of reinforcement plate.
It is thermosetting resin that described construction formwork, veneer post the used bonding adhesive of oriented structure chipboard.Thermosetting resin commonly used is phenolic resins, Lauxite or melamine resin.These resins all are the water resistance adhesive made of synthetic resin.
Described construction formwork, wherein impregnated paper adopts synthetic resin dipping, brushing or the method for roller coat or the mode that these methods mutually combine to handle facing plate body paper, and dryness finalization forms again.Facing plate body paper requires quantitatively at 70g/m
2Above effect is better.Used synthetic resin comprises thermosetting resins such as phenolic resins, Lauxite, melamine resin, diallyl phthalate resin, and the modified resin of these resins.The synthetic resin consumption that impregnated paper adopts is 10～200% of a facing plate body paper over dry quality.
The manufacture method of described construction formwork comprises the following steps: when only pasting veneer on the oriented structure chipboard surface
(1) oriented structure chipboard being carried out the fixed thick sanding in surface handles;
(2) adopt the water resistance adhesive made of synthetic resin, post the wood single-plate of suitable thickness;
(3) hot pressing forms required construction formwork.
