What Are the Uses of Faux Wood?

Wood-based panels are wood or other non-wood plants as raw materials. After being separated into various unit materials through a certain mechanical processing, they are plate or molded products made with or without the application of adhesives and other additives. It mainly includes three major categories of products, such as plywood, particleboard and fiberboard. Its extended products and deep-processed products reach hundreds of types. The birth of wood-based panels marked the beginning of the modernization of wood processing. In addition, wood-based panels can also improve the overall utilization of wood, and 1 cubic meter of wood-based panels can be used instead of 3 to 5 cubic meters of logs.

At the beginning of the 1st century BC, the Romans were already familiar with veneer manufacturing technology and

With the increasing number of new varieties of wood-based panels, their classification methods are constantly changing. There are several common classification methods:

1. Large format, good structure and convenient construction;

2. Low expansion and contraction rate, stable size, uniform material than sawn timber, difficult to deform and crack;

3. The veneer and various scraps used as raw materials for wood-based panels are easy to impregnate, so they can be used for various functional treatments (such as flame retardant, anti-corrosion, anti-shrink, abrasion resistance, etc.);

4. Wide range of thickness and density grades have strong applicability;

5. Good bending performance.

1. The plywood is made of raw wood softened by cooking, cut into large sheets, and then the wood fibers are placed perpendicular to each other, bonded with a good water-resistant synthetic resin glue, and then pressed, dried, sawn, and trimmed. Made of sheet metal. The number of layers is odd, generally 3-13 layers, which are called plywood and plywood. The tree species used to make plywood are alder, birch, ash, beech, colored wood, eucalyptus and so on.

2. Fiberboard is a board made by crushing, soaking, and grinding waste materials such as bark, wood shavings, and branches into wood pulp, and then pressing and drying. Due to different temperature and pressure during molding, it can be divided into three types: hard, semi-rigid and soft.

3. Particleboard is a board made by pressing wood shavings or wood fiber materials with or without rubber. Particleboard has low density and uniform material, but is easy to absorb moisture and has low strength.

4. Joinery board is a kind of artificial board made of trimming, planing and sizing, splicing, and veneering. The core of the board generally adopts short and fully dried wood strips, and the board surface adopts single-layer thin wood or plywood. Blockboard is not only an effective measure for the comprehensive utilization of wood, but also the obtained board has a uniform structure, stable size, large format and large thickness. In addition to surface decoration, it can also be used as a construction material.

5. Others for the manufacture of wood-based panels: The raw materials used for wood-based panels, except for plywood need to use logs, most of them come from cutting and processing residues, as well as small-diameter wood (diameter below 8 cm). The flakes, strips, needles, and granular materials made after being crushed or chipped and then broken can be used in the manufacture of particleboard. Wood chips are used for fiberboard manufacturing after fiber separation. In this way, the utilization rate of wood can be increased by 20 to 25% compared with the traditional utilization method. In the 1970s, attention was paid to the use of bark and sawdust as raw materials for artificial boards, but bark can only be used in the middle layer of particleboard, and the amount cannot exceed 8%, otherwise the product strength will be reduced. In addition, non-wood materials have also received increasing attention. In addition to bagasse, hemp stalks, etc., which have long been used in the production of wood-based panels, they have been expanded to a variety of plant stems and seed husks.

With the rapid development of the building decoration and furniture industry, the domestic demand for wood has increased sharply, and the gap in wood supply has become increasingly prominent. The development of wood-based panel industry is conducive to alleviating the contradiction between China's timber supply and demand and is an important way to save timber resources.

In 2006, the total industrial output value of China's wood-based panel processing industry above designated size reached 154,571,924,000 yuan, an increase of 32.49% over the same period of 2005. Cumulative product sales revenue for the whole year was 147,444,650 million yuan, an increase of 32.10% over the same period of 2005. The total accumulated profit was 7,039,148,000 yuan, an increase of 38.84% over the same period in 2005.

In 2007, China's wood-based panel processing industry above designated size realized a cumulative total industrial output value of 221,905,431,000 yuan, an increase of 41.72% over the same period of 2006. From January to October 2008, China's wood-based panel processing industry above designated size realized a cumulative industrial output value of 240,548,404 thousand yuan. This is an increase of 34.17% over the same period in 2007.

While the wood-based panel industry is developing, there are also problems such as irrational product structures and low product technical content; low levels of enterprise management, low product qualification rates; shortage of resources, and low industrial concentration. To this end, the development of the wood-based panel industry should implement measures to increase the technical content of the product; expand the scale of production; standardize management and other measures to improve the overall level of China's wood-based panel industry.

In 2007, the industry's product structure will become more reasonable, product quality will steadily improve, inferior products will gradually withdraw from the market, and product prices will become more rational. In addition, the national or industrial standards of China's wood-based panel products have been revised in the past one or two years, and the level has been improved. This has made our product quality closer to the world level and the indicators more reasonable. With the improvement of people's living standards, the position of wood-based panels in social development is becoming more and more important. In the future, wood-based panels have a huge market development space.
