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 purchasing methods of plywood? Let's have a look at
it with me.

1.What are the characteristics of plywood

Plywood has balanced high strength and is not easy to shrink, expand and deform. Plywood is not easy to crack and will not crack when nailing or screwing. Because plywood is man-made, it has a wide range
of sizes and can be customized according to different needs. Plywood surface modeling is easy. In modern architecture, it is most suitable to use plywood to finish the surface design. Plywood is light in
weight and easy to produce, move and install.

2.Advantages and disadvantages of plywood

Advantages of plywood
(1) Plywood will not produce any sawdust in the production process, and the utilization rate of wood is high, which can effectively save wood.
(2) Plywood has excellent bending resistance and is not easy to deform. It is convenient for transportation and construction and has good decorative effect.
(3) After boiling, plywood has strong weather resistance, is not afraid of high temperature, and has a long service life.

Disadvantages of plywood
(1) The surface of plywood is not particularly smooth and flat, and is not suitable for making single-sided parts, such as cabinet door and window sash, which cannot be made of plywood.
(2) If the plywood is not fully dried, the quality is unqualified, and it is easy to deform during use, and it is difficult to recover by external force.

3.What are the purchasing methods of plywood?

1)See whether it is environmentally friendly and whether the emission of harmful gases meets the national standards, especially whether the formaldehyde emission limit of plywood exceeds the standard.
For these too professional things, most owners may not understand and can not measure them. Xiaobian reminds you here that you can choose to see if the manufacturer has the China Environmental Labeling
Product Certification, because to pass the certification, it must be based on the double standards of quality and environmental protection. (For example, Xuebao plate has the certification of Chinese
environmental label products)

2)According to the materials, the prices of different tree species are also different. You can purchase different kinds of materials according to different needs.

3)In terms of technology, plywood has the difference between the front and the back. When purchasing, the plywood board shall have clear wood grain on the surface, the front side shall be smooth and flat
without stagnation, and the back side shall not be rough at least, without nodes; Even if any, 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 selecting plywood, pay attention to whether there is degumming phenomenon. When selecting plywood, you can knock each part of the plywood with your hand. If the sound is clear and
uniform, it will prove that the quality is good; If the sound is dull and uneven, it means that the splint has dispersed.

4) Look at the appearance. When purchasing, you should clearly see whether each plywood has blisters, cracks, wormholes, damages, stains, defects and excessive repair stickers.

Some plywood is made by pasting two veneers with different grain, so when selecting, attention should be paid to whether the plywood seam is tight and whether there is uneven phenomenon.

Summary: The above is an introduction to the characteristics of plywood and the purchase methods of plywood. Finally, I hope this article can help you.
