What are the advantages, disadvantages and uses of plywood? In home decoration, various boards must be used. At present, artificial boards have replaced the earlier solid wood boards and become the main materials in decoration construction. Plywood is one of the three major boards of wood-based panels and has its own unique advantages, but it is often this type of board that confuses consumers. Today, I will introduce the advantages, disadvantages and uses of plywood in detail.
1. What is plywood
Plywood is commonly known as plywood and thin core board. It is a kind of artificial board first used in the decoration industry. Or pressed perpendicular to each other without heating. The classification of plywood is based on its thickness, generally divided into 3, 5, 9, 12, 15, and 18 cm. The six specifications of the board.
2. the advantages of plywood
①. In the production process of plywood, no sawdust is produced, which can make reasonable and effective use of log resources, improve the utilization rate of natural wood, and is an important way to save wood.
②. The plywood has light bulk density, good bending resistance, convenient transportation and construction, and beautiful texture, which makes up for the defects of some wood naturally generated, and has good decorative properties. In some structural parts that need to bear weight, the use of plywood will have more strength.
③. The boiled plywood has strong weather resistance, high temperature resistance and durability. It can be used in aircrafts, ships, trains, automobiles, home improvement, construction and containers where sheet metal is required.
3. Disadvantages of plywood
①. There is no MDF on the surface of the plywood, and the solid wood board is clean and smooth. It is not suitable for single-sided parts, such as cabinet facades, window sashes, etc.
②. The plywood that has not been fully dried may have problems such as substandard quality and production process, which will lead to serious deformation of the plywood when it is used, and it is difficult to adjust it by external force.
③. There is also a kind of plywood, which uses plywood as the base layer, and pastes decorative materials such as fireproof board and aluminum-plastic board on its surface. This type of plywood structure is not as strong as ordinary MDF.
4. the characteristics of plywood
①. Plywood not only has all the advantages of natural wood, such as light bulk density, high strength, beautiful texture, insulation, etc., but also can make up for some natural defects of natural wood, such as knots, small size, deformation, and large differences in vertical and horizontal mechanics. .
②. The production of plywood can make rational use of logs. Because it has no sawdust, every 2.2-2.5 cubic meters of logs can produce 1 cubic meter of plywood, which can be used instead of about 5 cubic meters of logs sawn into boards, and every 1 cubic meter of plywood products produced can also produce 1.2-1.5 cubic meters of residue. Rice, which is a good raw material for the production of medium density and particleboard.
Because plywood has the advantages of light bulk density, high strength, convenient construction, no warping, and good horizontal grain tensile mechanical properties. Therefore, plywood products are mainly used in various boards for furniture manufacturing, interior decoration, and residential construction. Followed by shipbuilding, car box manufacturing, various military, light industrial products and packaging and other industrial sectors.
Five, the use of plywood
The advantages of plywood, such as small deformation, large format, convenient construction, and good horizontal grain tensile performance, make it more and more widely used in furniture manufacturing, such as cabinets, cabinets, tables, chairs, etc.; interior decoration includes ceilings, wall skirts, floor linings Plates, etc.; concrete building formwork, building components, etc. in engineering construction; as well as vehicle and ship manufacturing and packaging industries.
