In recent years, there has been such a phenomenon that whenever the wood-based panel market is weak, many people will use the OSB oriented particle board to say things. "OSB oriented particle board almost occupies more than half of the European and American wood-based panel market. In home decoration, they prefer to use oriented strand board and rarely use blockboard. Today in Europe and America is China's tomorrow." Many people in the industry hold this view.
So, is this really the case?
Can OSB Oriented Strand Board be able to replace China's Big Brother Blockboard in China?
In fact, as early as 1985, China introduced the first OSB production line. But after 30 years, OSB has not been able to stand alone in China.
Why is this?
To answer this question, first of all, we find out why OSB can become the mainstream of the European and American markets?
In Europe and the United States, oriented strand board is the assembly line operation, efficiency is the main means to reduce costs; and blockboard is different, due to the small diameter of raw materials, the workload of stitching and repairing is large, requiring a lot of human resources. As we all know, in Europe and the United States, the unit labor wage is very expensive, which is why the European and American oriented particle board gradually replaces the blockboard.
However, at present, China is in a labor-intensive stage, and the unit labor wage is far lower than that of European and American countries. Blockboard can be produced in units of sections, can be discontinued, and is suitable for labor-intensive production in areas with low wages.
Second, the use of the two is different. In Europe and the United States, oriented strand board is mainly used for wooden house structure, while China is mostly reinforced concrete building; most of the packaging materials in Europe and America are oriented strand board, and the Chinese people have not been so extravagant, for example, can use 2.7 mm thick three-ply board, why use 6 mm Oriented strand board! The same is true for cement formwork, vehicle and ship materials.
In addition to the above macro factors, OSB oriented strand board can not replace the blockboard, but also includes its own shortcomings:
1. Destroy log properties
As we all know, the blockboard is a kind of plywood. It is made of two veneers laminated in the middle of the veneer, so it maintains the mechanical and physical properties of the logs to the utmost extent. The OSB oriented strand board belongs to the scraping board and is pine. Or poplar peeled, cut into flaking along the direction of wood grain, usually 40~120mm long, 5~20mm wide, 0.40~0.60mm thick, and then dried, sized, paved into slab, hot pressed Made of. It is because of this manufacturing process that OSB largely destroys the properties of logs.
2. Comprehensive performance is inferior to blockboard
In the gluing process, the OSB shaving agent adhesive is only in the form of spot welding, while the blockboard is evenly coated. At the same time, the core board of the blockboard produced in China basically adopts finger joint and side glue. The ground has improved the lateral static bending strength, and the dimensional stability is much higher than the OSB.
The experimental data shows that at the same density, the elastic modulus, nail holding power, especially the lateral nail holding force and the uniformity of the board surface of the OSB are lower than that of the blockboard. If the OSB is to be level with the blockboard in these properties, the density of the OSB must be higher than that of the blockboard. Generally speaking, it is heavier than the blockboard and the wood used needs more.
3. Cutting and opening difficult, explosive edge
When making furniture, OSB cutting is more difficult than blockboard. If the stakeout is not straight, or the speed of the hand saw is not fast enough, or the saw blade is not sharp enough, it will directly lead to the edge of the particle board not being neat and tidy. side.
The blockboard will not have an appeal problem, the edges are neat and beautiful, and the furniture made with it will not cause blasting.
4. The edge is not beautiful
There is currently no complete solution for how to close the OSB edge. Currently, the common method is to use acrylic or solid wood edge strips, but due to the inconsistency between different materials, it will cause the edge strips to fall off during use. The surface texture is not matched, and the overall harmony and beauty cannot be achieved.
(So ​​the interior designer said that OSB particleboard is definitely not the first choice when selecting materials or making shapes.)
5. The corners are unqualified and cannot be used for children's furniture.
On August 1, 2012, China's first mandatory national standard for children's furniture GB28007-2011 "General Technical Conditions for Children's Furniture" was officially implemented, and mandatory requirements were imposed on furniture products for children, which clearly required all children's furniture to be required. Grinding to prevent sharp, protruding parts from causing harm to children.
The furniture made with OSB oriented strand board is difficult to round, so when we make children's furniture, we will basically abandon OSB and choose more blockboard.
Of course, this is not absolute. If you use the large lines to edging the corners of the OSB, you can still achieve the rounding requirements, but the aesthetics are basically gone!
It is undeniable that OSB oriented strand board also has advantages, such as automation, mechanization and comprehensive utilization, which is unmatched by blockboard. OSB is not completely in conflict with the market of blockboard in the Chinese market. OSB prefers the consumer sectors such as load-bearing, outdoor huts and packaging, rather than directly replacing the blockboard market.
What's more, "Orange is Huainan, it is orange, and in Huaibei, it is æž³." There is still a difference between the European and American consumption views and China's consumption concept. OSB is suitable for the European and American markets, and the blockboard is more in line with China's basic national conditions, whether it is in manufacturing characteristics or market conditions. Therefore, for a long time in the future, blockboard is still in the position of big brother in the Chinese wood-based panel market.
