Plywood is not only affordable, but also very durable, so it is widely used in home decoration. What are the characteristics of plywood? What are the purchase methods of plywood? Let’s learn about it with me.
What are the characteristics of plywood? What are the options for plywood?
1、 What are the characteristics of plywood
1. In the production process of plywood, there is no sawdust, which can make rational and effective use of log resources and improve the utilization rate of natural wood. It is an important way to save wood.
2. Plywood has light unit weight, good bending resistance, convenient transportation and construction, and beautiful texture, which makes up for the defects of some natural wood and has good decoration. In some structural parts that need load-bearing, the use of thin core board will have more strength.
3. Plywood has strong weather resistance, high temperature resistance and durability. It can be used in aircraft, ships, trains, automobiles, home decoration, buildings, containers and other places where plates need to be used.
2、 What are the options for plywood
1. See whether it is environmentally friendly and whether the release of harmful gases meets the national standards, especially whether the formaldehyde release limit of plywood exceeds the standard. For these too professional things, the vast majority of owners may not understand and cannot measure them. Xiaobian reminds you here that you can choose to see whether the manufacturer has China environmental labeling product certification, because to pass the certification, it must be based on the premise of double standards of quality and environmental protection.
2. Depending on the materials, the prices of different tree species are also different. You can purchase different kinds of materials according to different needs.
3. Look at the craft, the plywood has the difference between the front and the back. When purchasing, the plywood surface shall have clear wood grain, the front side shall be smooth and flat without stagnation, and the back side shall at least not be rough and free of nodes; Even if there is, it shall 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.
If the sound of each part of plywood is even, pay attention to whether it can be degummed by hand. Therefore, when selecting the part of plywood, pay attention to whether it can be degummed by hand; If the sound is dull and uneven, it indicates that the splint has been released.
4. Look at the appearance. When purchasing, you should clearly see whether each plywood has bubbles, cracks, wormholes, damage, stains, defects and too large repair stickers.
Some plywood is made of two veneers with different grain pasted together. Therefore, when selecting, we should pay attention to whether the joint of plywood is tight and whether there is uneven phenomenon.
Summary: the above is all about the characteristics of plywood and the purchase methods of plywood. Finally, I hope this article can help you.
