Another nameNorth American juniper.

    

It belongs to the family Cypressaceae, an evergreen tree, up to 30 meters high, native to North America. Strong adaptability, drought-resistant, low-humidity resistant, not only cold-resistant but also heat-resistant, resistant to barrenness, and can grow on various soils. It is resistant to pruning and has strong shade tolerance. It is better than arborvitae as a hedge. The lower branches are not easy to wither, and the color does not change brown or yellow in winter. It can be planted in the shade on the north side of the building. In ancient times in our country, it was mostly planted in temples and tombs as tomb trees or Berlin. Its tree shape is beautiful, and its branches are erect or oblique. Two types of leaves, spiny leaves alternately opposite, covered with white powder, scale leaves grow on quadrangular branchlets, diamond-shaped ovate, apex acute or acuminate, with concave glands in the middle and lower part of the back of the leaf

Trees and distribution: large trees, 30-50m high, 1-1.6m in diameter, good trunk shape. Distributed in Southeast Asia, Sumatra, Borneo.

Characteristics: Diffuse-porous. The heartwood is light yellow-brown, exposed to the atmosphere for a long time, the color of the wood turns darker, showing straw yellow-brown, the new cut surface of the sapwood is yellow, and it is easy to be infected by discoloration bacteria and becomes light gray-brown.

科技木 (TEC)

    

Technical wood is also called recombined decorative veneer.

 

Technological wood is a new type of all-wood decorative material with superior performance, which is made of ordinary wood (fast-growing wood) as raw material, using the principle of bionics, and through various modified physical and chemical treatments of ordinary wood and fast-growing wood. Compared with natural materials, it hardly bends, cracks, or twists. Its density can be controlled artificially, and the product has good stability. In the process of processing, there is no waste and value loss of natural wood processing, and the comprehensive utilization rate of wood can be increased to more than 86%.

Compared with natural wood, technological wood has the following characteristics:

In the process of processing, there is no waste and value loss of natural wood processing, and the comprehensive utilization rate of wood can be increased to more than 86%.

 

Product performance is superior

   The physical properties of technical wood such as density and static bending strength are superior to its raw material natural wood, and it is anti-corrosion, moth-proof, moisture-resistant and easy to process. At the same time, it can also be processed into different format sizes according to different needs, overcoming the limitations of natural wood diameter grades.

The utilization rate of finished products is high, and the decoration is more economical

   Technological wood has no natural defects inherent in natural wood such as wormholes, knots, and discoloration. It is a decorative material with almost no defects. At the same time, its texture and color have certain regularity, so it avoids such The annoyance of difficult splicing of natural wood products due to differences in texture and color allows consumers to make full use of every inch of material they buy.

The birth of technical wood products is an excellent substitute for the increasingly scarce natural forest resources. It not only satisfies people’s demand for the decorative effect and dosage of different tree species, but also enables the continuation of precious forest resources. At the same time, E1 environmental protection glue is used in the production process of technological wood, and the five major products (plywood, veneer, solid wood composite floor, technological wood sawn timber, technological wood slices) all meet the requirements of GB18580-2001 standards, and all have obtained “China Environmental Labeling Products Certification”. It is a real green product.

    Technological wood is an “upgraded version” of natural wood, “derived from nature and better than nature“, and can be widely used in furniture, decoration, flooring, veneer, doors and windows, sports materials, wood carving, handicrafts and other fields. Among them, the product with the largest sales volume is the technological wood decorative veneer as a decorative material. With its irresistible charm, it is favored by more and more manufacturers in the fields of furniture, decoration, speakers, doors and windows. As its main raw material, veneer replaces natural wood; secondly, colorful technological wood has also been widely used in wood lines, handicrafts, spectacle frames, spectacle frames of technological wood color wood (24 photos), special wooden shoes, sports goods production and other fields. good application.
