Thin wood veneer
1. Classification of thin wood 4, preservation and use Bulk grain van has van, tank car, and some cars also with such as air suction and other special loading and unloading functions. In general, bulk grain transport vehicles with loading and unloading speed, to prevent sand and snow effect, suitable for large tonnage transport and other characteristics, widely used in grain-producing farms, large grain depots, flour mills, instant noodles factory, Food transport Bulk Truck,Bulk Feed Transport Truck,Bulk Powder Truck,Bulk Grain Transport Truck CLW GROUP TRUCK , https://www.clwgrouptruck.net
(1) Classification by its form and composition
Natural thin wood: A thin wood made directly from the wood of natural precious tree species.
Artificial thin wood: A thin wood made from a single board of a common tree species, dyed, assembled, and glued into wood, and then sliced, and the thin wood pattern is artificially combined.
Integrated thin wood: The whole piece of parquet is made from wood of precious tree species according to the desired pattern glue and then sliced.
Dyed wood: A thin wood made by dyeing light-colored thin wood.
Composite thin wood: Thin wood made of composite wood and paper, plastic film, metal film, non-woven fabric, etc., is flexible and can cover the curved surface.
(2) Classified by thickness
Thin wood: Thin wood with a thickness greater than 0.5 mm generally refers to thin wood with a thickness of 0.6 to 0.8 mm, which is commonly used for particleboard substrates.
Thin wood: Thin wood with a thickness of less than 0.5 mm, generally thin wood with a thickness of 0.2 to 0.3 mm, commonly used for plywood, medium density fiberboard substrates.
(3) Classified according to its manufacturing method
Rotary cut wood: A thin wood made by a rotary cutting method with a chord cut pattern.
Sliced ​​veneer: A thin wood made by a planing method with a cut surface or a string cut surface pattern.
Semicircular Rotary Thin Wood: A thin wood made by a semicircular rotary cutting method having a diameter cut surface or a string cut surface pattern.
(4) Classification by tree species
Commonly used tree species are: ash, eucalyptus, elm, eucalyptus, red eucalyptus, white eucalyptus, ash, sebili, walnut, beech, maple, teak, rosewood and so on.
(5) Classification by its pattern
Diaper-cut thin wood: Straight parallel stripes made of wood early and late.
Chord cut thin wood: The wood is composed of early and late wood, which is roughly a mountain-shaped pattern.
Corrugated thin wood: A pattern produced by wavy or twisted texture, also known as the back of the piano pattern, shadow pattern, often appear in maple (Maple), birch and other tree species.
Bird-eye thin wood: A bird-like pattern formed by partial distortion of fibers, often found in maple (Maple), birch, and ash.
Tree-skinned thin wood: The pattern formed by the abnormality of the local fibers caused by tree tumors, etc., often appear in walnut, maple (Maple), French paulownia, elm and other tree species.
Tiger-skinned thin wood: A pattern resembling a tiger skin that is formed by a dense wood beam on a radial section. The wood ray has a spindle shape on the chord section, and is often found in tree species with broad wood ray, such as eucalyptus and beech.
2, size tolerance
The thickness of the sliced ​​veneer is ±0.03mm.
3, moisture content
The moisture content of sliced ​​thin wood products is 8-16%.
The moisture content of the thin wood after drying is generally kept at about 20%, so as to be preserved and prevented from being broken and warped.
Undried micro-thick wood should be protected from moisture and mildew during storage. Therefore, winter thin wood should be covered with polyvinyl chloride film and stored in cold storage in summer. Generally, such thin wood should not be stored for a long time, and should be used with the planer in production, and should not be stored. When it is exported, it should be properly dried to a moisture content of 20% to 30%, and after being treated with mildew, it is densely packed and bundled with a polyvinyl chloride film and a splint.
The use of thin wood is mainly used as a veneer material, or as a curved part for making curved wood furniture, and a side treatment of a plate.
