Plywood is to use glue to glue veneers or thin plates formed by rotary cutting wood under temperature and pressure for a certain period of time to form a plate-like material. Plywood is often used in home decoration. Facing the variety of plywood on the market, how to choose? What are the advantages of plywood? Let's find out with me below.
1. How to choose plywood
1. Check whether it is environmentally friendly, whether the release of harmful gases meets the national standard, especially whether the free formaldehyde released by the glue exceeds the standard. For these overly professional things, most owners may not understand and cannot measure them. The editor tells you that you can choose to see if the manufacturer has China Environmental Labeling Product Certification, because in order to pass the certification, it must be based on quality and environmental protection. Double compliance is the premise.
2. Look at the appearance. When purchasing, you should clearly see whether each piece of plywood has bubbles, cracks, wormholes, damage, stains, defects, and excessive repair stickers.
Some plywood is made by pasting two veneers with different textures together, so when choosing, you should pay attention to whether the joints of the plywood are tight and whether there is any unevenness.
3. Look at the process, the plywood plywood has a difference between the front and back. When purchasing, the surface of the plywood board should have clear wood grain, the front should be smooth and flat without a sense of stagnation, and the reverse should at least not be rough and have no nodes; even if there is, it should be smooth and beautiful without affecting the construction.
If the plywood is degummed, it will not only affect the construction, but also cause greater pollution. Therefore, when choosing plywood, pay attention to whether there is degumming. When choosing, you can tap the various parts of the plywood with your hands. If the sound is crisp and uniform, it proves that the quality is good; if the sound is dull and uneven, it means that the plywood has been loose glue.
4. Depending on the material, the price of different tree species is different. Owners can purchase varieties of different materials according to different needs.
2. What are the advantages of plywood?
1. Plywood not only has all the advantages of natural wood, such as light weight, high strength, beautiful texture, insulation, etc., but also can make up for some natural defects of natural wood, such as knots, small format, deformation, and large differences in vertical and horizontal mechanics.
2. Plywood production can make rational use of logs.
3. Due to the advantages of small deformation of plywood, large format, convenient construction, not easy to warp, and good tensile mechanical properties of transverse grain. Therefore, this product is mainly used in various panels for furniture manufacturing, interior decoration, and residential construction. Secondly, it is used in industrial sectors such as shipbuilding, carriage manufacturing, various military industries, light industrial products, and packaging.
Summary: The above is the introduction of how to choose plywood so as not to step on thunder and the advantages of plywood. Finally, I hope this article can help everyone.
