How to distinguish natural bark from scientific bark?

Natural wood veneer is a common furniture board used in furniture and wood decorative panels at this stage, which is derived from pure natural wood after steaming and planing. At present, the common natural bark thickness is 0.5mm, which is also called 50 silk. There are many types of bark. At this stage, there are about 300-500 kinds of bark in China. The prices of different types are very different, including domestic and imported materials.

With the increasing demand for natural wood veneer in China's home decoration industry, imported raw wood veneer is basically dominant at this stage, with North American wood and African wood as the key. At the same time of continuous improvement, pure natural wood is also increasingly anxious, so the scientific and technological veneer is born at the right time. Technology veneer raw materials are also from pure natural wood.

1、 Difference between natural bark and technological bark

1. Natural wood veneer is produced and processed from pure natural wood, and its technological process is carried out through high-temperature steaming, sectioning, drying, cutting, labeling and metrological verification. The veneer is divided into flat cutting and rotary cutting machines according to different cutting methods. The lines produced and processed by different cutting methods are also very different. At this stage, the common natural veneer is dominated by flat cutting veneer, which is generally divided into mountain grain and straight grain, of course wide. The veneer from the rotary cutting machine is generally of large specification, and the common specification is 1220x2440mm. The veneer from the rotary cutting machine is commonly used to make wood decorative side plates or other furniture products.

2. Science and technology veneer is a kind of veneer produced and processed by human based on the basic principle of human bionics, referring to the natural veneer grain. It is also derived from pure natural wood. It is just a kind of veneer produced and processed after coloring and asset restructuring according to the method of high-tech improvement. The basic specification of science and technology veneer is 2500x640mm, so the most immediate way to distinguish is the different specification of the two kinds of veneers, The technical veneer specification is fixed, and the grain and color are unified. It looks rigid. However, the natural bark is derived from pure natural wood, so it is quite natural that its grain changes. It is not the same tree that has a significant difference in hue and texture.

2、 Analysis of advantages and disadvantages of natural wood veneer and scientific wood veneer

1. The advantage of natural wood veneer is the grain. Of course, there are many kinds of wood veneer. The price can be divided into different levels according to the kind of wood veneer, which can reach different consumer markets. For those who like the natural solid wood board, the natural composite solid wood flooring furniture has reached this kind of consumer group very well. Compared with pure solid wood furniture, the cost is saved a lot.

2. Defects of natural wood veneer: along with the improvement of the furniture product consumption market, pure natural resources are becoming more and more anxious. For some special species, such as Indonesian ebony and Mexican Acacia, which belong to green plants, their growth cycle must not be counted for several years. Therefore, this kind of wood has been limited to import and export by the producing countries, which has pushed up the price of scarce natural wood veneer. Since natural bark is derived from wood, its own shortcomings cannot be prevented, such as mineral lines, black knots, white frames, wormholes, etc. The built-in defect of this kind of wood endangers the quality of natural wood veneer. If we want to prevent this defect, it will reduce the utilization rate of wood in the production process. Lead to energy supply consumption.

3. Advantages of sci-tech veneer: sci-tech veneer is a kind of veneer that is produced and processed according to the high-tech method of human improvement. Its color tone and texture are relatively unified, and the types are relatively rich. The defect of natural wood veneer is eliminated. The price is also more cost-effective, the specifications are unified, and the utilization rate of wood veneer is high.

4. Defects of science and technology veneer: since science and technology veneer is produced and processed manually, its grain looks rigid. No matter how to improve it, it is not as good as natural veneer. In addition, science and technology veneer is bonded according to strong glue in the whole process of asset restructuring, and its strong glue formaldehyde concentration is too high. Now that China advocates environmental protection and physical and mental health, the environmental protection standard of science and technology veneer is not as good as natural veneer, Natural science and technology veneer manufacturers have also noticed this problem and reduced the formaldehyde concentration according to high-tech methods. Make raw materials healthier. But no matter how it is improved. Its environmental protection is not as good as natural bark.

The above is the analysis of the advantages and disadvantages of natural bark and scientific bark and the summary of the differences between the two kinds of bark. I believe you have read this article and have a deeper understanding of both. With the improvement of production and processing technology, natural veneer and scientific veneer have also taken another step towards the road of sustainable development.
