OSB   has been widely used in villas, furniture, packaging, etc.. It is one of the new high-strength solid environmental friendly wood panel. The formaldehyde emission of OSB board is 0.02mg/m3, which is equivalent to smoking a cigarette in a 100 square metersom room , which greatly exceeds the indoor air quality standard currently implemented in my country (<=0.08mg/m3), also it greatly reduced the amount of large-caliber wood. The quality features of OSB board: * Healthy and environmental friendly, formaldehyde release of OSB is almost zero, with a clear woody fragrance; * Uniform force, good strength, very good stability; *Unique structure, strong plasticity, easy to paint directly; *No voids, scars, uniform density, thickness, and strength; * No moth-eaten phenomenon, can be used as packing box, no need for fumigation; *The expansion coefficient is small, the water content is 9±4%, and it is also waterproof and moisture-proof; * High utilization rate, no waste, heat preserva...

Concrete pouring has always been an important part of engineering construction, and the construction difficulty can not be ignored. Although the wide application of construction formwork can save labor costs to a large extent, the premise is that the quality and type of formwork match. Considering the increasingly mature technology of formwork products, plywood formwork with features of convenient disassembly and assembly is favored. In this way, it is wise to reduce the difficulty of concrete pouring by relying on it. The careful selection of formwork products is to avoid construction delays caused by uncertain factors in the construction process, so it is particularly necessary to pay attention to the quality of formwork.  It is important to know that plywood formwork, as a common basic building material, has many advantages such as accurate size and convenient erection. Although there are many types of  film faced plywood  products, it is still necessary to formulate ...

The origin of  plywood  is divided into three categories: imported boards, joint venture boards, and domestic boards. Common specifications mainly include 1220×2440×3 mm and 1220×2440×5 mm; other specifications of building formwork include 1220×1830×3 mm or 5 mm, and 915×1830×3 mm or 5 mm. There is also a special bag door with specifications of 915×2135×3 mm and 1220×2135×3 mm. The plywood of other specifications is small-format plywood, which is not commonly used for decoration. Multi-layer plywood is 7 or more layers, mainly used for construction and vehicles. When purchasing plywood, remember to find out the specifications and sizes. Consumers can calculate the amount of building formwork materials required according to the area of interior decoration to avoid unnecessary waste caused by blind purchase.

The physical and mechanical properties of   oriented strand board   are superior to ordinary particle board, it have the following characteristics: 1. Anti-deformation, anti-peeling, anti-warping, with uniform strength and stable size; 2. Anti-corrosion, anti-moth, strong flame-retardant ability, can be used in outdoor and high-temperature environments; 3. Good waterproof performance, can be exposed to natural environment and humid conditions for a long time; 4. It has good machining performance and can be cut, drilled and planed in any direction; 5. It has excellent in heat insulation and sound insulation, also it has good finishing paint performance.

There is a shortage of large-diameter high-quality wood resources in my country, but we has abundant fast-growing wood resources.   Oriented strand board   uses fast-growing wood as raw material, which has high material utilization rate and good physical and mechanical properties, excellent processing performance, also it is enviroment friendly. Oriented strand board is popular for furniture enterprises, and it plays an important role in our modern life with its unique quality. However, its development in my country is still in its infancy, with the acceleration of urbanization in my country and the improvement of oriented board processing technology and equipment, the application field of oriented particle board will continue to expand, it will has a broad market and good development prospects.

OSB   is short of oriented strand board, also called oriented fiberboard. It is made of 100% logs, peeled, sliced, and processed along the direction of the wood grain to grow into wood chips of 40mm-120mm, width 5mm-20mm, and thickness 0.3mm-0.7mm. Then, do high-temperature drying, added high-performance glue and waterproof, layer them according to their latitude and longitude directions, and are made under high temperature and high pressure. OSB adopts solid wood lamination technology and "zero formaldehyde" technology, it not only retains the natural characteristics of wood, but also endows OSB board with more excellent characteristics than solid wood. It has some advantages such as high bending strength, strong moisture resistance, small linear expansion coefficient, stable size, uniform material, nail holding force, strong impact resistance, easy processing, etc. OSB has been widely used in villas, furniture, packaging, etc. in the world. It is one of the new high-strengt...

Adjusting the internal moisture content according to the relative specifications and tree species in the produce processing. Let's take a look in detail. It must be cut into the same proportion of wood layers according to the size before making, and the impurities on the surface of the wood layer must be cleaned up. Because the layer has too much moisture, drying equipment must be used for mass production, and the moisture content should be controlled at 8% -12%. The processed product is in a fragile state. It needs to be placed for two to three days to stabilize the performance quality. You can choose to dry in the sun to ensure the dry state of the product if in small quantity. The above is the drying process shared by the  plywood formwork  manufacturer for you.
