It is characterized by that the larch is treated through softening degreasing, revolving cutting into single plate, drying, dressing forming bland and hot pressing into container baseboard with following physical properties; static bending strength (longitudinal) equal to or greater than 75 MPa; static bending strength (horizontal) equal to or greater than 30 MPa; modulus of elasticity (longitudinal) equal to or larger than 10000 MPa; modulus of elasticity (norizontal) equal to or larger than 3000 MPa; density 0.65-0.85 g /cu.cm; and compression ratio equal to or larger than 20%.
Description
Tamarack container bottom board and manufacturing process belong to a kind of container bottom board and manufacturing process.
The freight container timber apron is different from normal plywood, and physical properties requirements such as MOR, modulus of elasticity, bonding strength, presentation quality, working accuracy are very high in length and breadth for it.Therefore, nearly all to rely on the high-density hard timber of growing in the hylaea be raw material to world's container bottom board in decades.Because this seeds growth cycle is long, the cutting large resource is day by day poor.The scholar of part businessman has developed with the medium timber of density and has produced substrate, and the face basal surface glues together the composite bed of chemical industry fiber or high density Wooden veneer again, because this technical matters complexity, productive costs is higher, is not generally adopted by manufacturing enterprise.Used veneer of manufacturing enterprise of domestic a few family and juggle all rely on import, consume a large amount of foreign exchanges every year.To the continuous increase of freight container demand, protect limited hard wood resource along with in the world, the medium timber of developing density, what widen container bottom board is a far reaching problem with the material source.
The present invention its objective is development and use China density of wood medium seeds, particularly tamarack, aboundresources, moderate cost, beautiful texture is through the processing of science, rational assembly structure, make its increase in the density of density assortment reach a kind of novel wooden base plate of trans-container industrial standard.
Major technique solution of the present invention is, 1, softening degreasing, the warm water that the tamarack juggle is put into 25 ℃-30 ℃ soaked 6-8 hour, be warming up to 50 ℃-55 ℃ then, be incubated 6-8 hour, be warming up to 75 ℃-95 ℃ again, be incubated 18-20 hour, be cooled to 55 ℃-60 ℃ again, make juggle soften degreasing; 2, be peeled into veneer, 3, drying, 4, trimming, 5, gluing, use the phenolic resin glue of solids content, and add insect-proof agent at 48-50%, guarantee when hot pressing, to permeate uniformly in plate, reach the order ground of long-term insect protected.6 assemblies are mated formation veneer by crisscross, and face layer at the face base plate and respectively spread layer 2-3, and vertically long core veneer is hot pressed into the thick finished product of 28mm, guarantees to meet international standards requirement.
Most preferred embodiment:
Embodiment 1: is raw material with the tamarack, softens degreasing, be peeled into the veneer of thickness 1.85mm, and drying, trimming, the even level veneer is coated with phenolic resin glue 280-300 gram/m
