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:

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.

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.
