Veneer,, also known as thin wood, veneer, the English name of, during the import and export declaration, is also known as "veneer or veneer. Wood veneer is widely used in veneer decoration of furniture and other products. It is a kind of thin veneer or veneer material with the characteristics of precious tree species.
So far, the earliest use of wood veneer was found in Egypt 4,000 years ago. Due to the tropical desert climate, wood resources were scarce, but the ruling class was very fond of precious wood. Under this circumstance, craftsmen invented cutting wood.
The way wood veneer is made
From the point of view of the production method, wood veneer can be divided into chord cutting, diameter cutting, rotary cutting and cutting material, different cutting methods, the texture of wood veneer produced, wood veneer structure is different.
The string is cut
Plain Slicing, Flat cut -- also known as Plain Slicing, plane slice/Flat slice. Chord cutting wood veneer means that the Slicing cutter cuts wood pieces along the parallel line in the center of the log.
From the split log out of the string cut veneer, the most into a layer of rings will form a "cathedral" pattern of wood grain.
Rotary cutting
Rotary Cut - Mount the log in the center of the lathe, insert the slicer into the log at a slight Angle, and then rotate the log against the slicer to create a Rotary veneer. The wood veneer can be widened to provide a whole board (single board).
Diameter cut
Quarter Slicing -- Quarter Slicing is the growth rings of vertical tangential logs, producing straight grained veneer.
Rift cut
The Rift-Cut veneer is made of various kinds of oak. The pith rays of oak spread out from the center of the log like the curved spokes of a wheel. To minimize the appearance of "scaly" wood grain, the pith rays are cut into the oak at a slight Angle to produce a straight grained veneer.
The type classification of wood veneer
The charm of wood veneer lies in its unique grain, rich and beautiful color, as well as its natural beauty. The rigorous production process required to make natural veneer adds a different value.
Natural wood veneer
It has the natural and simple fragrance of wood, full texture, and its special and irregular natural texture. It has the artistic charm of being perfect and marvelous, which can bring people the artistic enjoyment of returning to nature with original heart and beauty.
Natural veneer is widely used: thin leather is used in the production of veneer, paper and non-woven cloth; Thick leather is used for veneer parquet, furniture making and composite floor surface.
Science and technology, wood.
Using bionics principle, the new wood material with better performance is made from the common fast-growing wood through high-tech processing and beautification. The book that USES science and technology wood to process becomes is called science and technology wood skin commonly.
Sci-tech veneer has the characteristics of rich lustre, diverse varieties, great potential for product development, large decorative size and convenient processing.
Dyeing wood veneer
The use of high-tech processing technology, the natural wood defects processing and coloring and made of a new decorative material, the domestic general term dyeing wood, wood veneer processing with dyeing wood called dyeing wood veneer.
Dyed wood veneer has the characteristics of natural texture, zero surface defects, green and environmental protection.
Production process of wood veneer
In general, the processing of natural thin wood is the use of cutting method. The process flow is as follows: log → truncation → profile → softening (steaming or boiling) → planing → drying (or not drying) → cutting → testing packaging → warehousing.
Here are just three important steps:
Sectional profile control
After the log into the factory, first of all, in accordance with the required length cut into sections, and then when cutting wood square, must be based on the diameter of the log, wood texture and wood square in the planer fixed method to choose sawing cutting scheme, so that the width of the planing thin wood is not less than the relevant requirements.
The reasonable plan not only gives the material rate to be high, and makes the diameter to cut the thin wood is much, the string to cut the thin wood is little, the product decoration value is high. Logs of different diameters should adopt different sawing schemes.
cooking
After cooking (heat treatment with water), wood plasticity increases. The most effective method that increases lumber plasticity is temperature and moisture content these two factors cooperate to adjust at the same time, raise lumber temperature namely the moisture content that increases lumber again at the same time. This is the actual production of commonly used saturated steam or hot water on the wooden square for cooking treatment.
When the wooden cube is put into the cooking pool, it should be carried out according to the tree species and the wooden cube specifications respectively; The water temperature had better keep normal temperature, and rise slowly, lest cause wooden square craze because of thermal stress.
dry
The moisture content after drying is generally required to be in 8%~12% is appropriate, the thin wood drying equipment has continuous operation of the drum type dryer and belt type dryer and intermittent operation of the drying chamber.
Drying chamber is old - fashioned drying equipment, very economical, but the drying quality is better. The most widely used is the drum dryer. Strip dryer must be used for thin wood, especially for thin wood with thickness less than 0.4mm.
