1. First of all, when purchasing, we should pay attention to whether the factory name, address and trademark of the production enterprise are complete. Because only the plates with complete marks can get the due quality assurance.

2、表面无明显瑕疵。板材表面应光洁、*刺沟痕和刨刀痕，无透胶现象，板面无局部发黄、发黑等污染现象。

2. The surface shall be free from obvious defects. The plate surface shall be smooth, * prick groove mark and planer mark, without glue penetration, and the plate surface shall be free of local yellowing, blackening and other pollution.

3、区分人造和天然贴面。通常人造薄木单板贴面的纹理基本为通直纹理，纹理图案有规则； 而天然木质单版贴面为天然木质花纹，纹理图案自然而无规则，变异性比较大。

3. Distinguish between artificial and natural veneers. Generally, the texture of veneer veneer is straight and regular; The natural wood veneer is natural wood pattern, the texture pattern is natural and irregular, and the variability is relatively large.

4、无开胶现象。胶和强度充分反映了板材胶合性能的优劣，胶合强度值约高，胶合性能就越好。 在选择板材时，应注意装饰板胶层结构稳定、无开胶现象。仔细观察，在表面单版与基材之间、基材内部各层之间不能出现鼓包、分层现象。

4. No glue opening. Glue and strength fully reflect the advantages and disadvantages of plate gluing performance. If the gluing strength value is about high, the gluing performance will be better. When selecting plates, attention shall be paid to the stable structure of the adhesive layer of the decorative plate and no glue opening. Carefully observe that there shall be no bulge and delamination between the surface single plate and the substrate and between the layers inside the substrate.

5、气味应清淡。装饰板使用的胶粘剂以脲醛树脂为主，装饰板材经*处理后，材质中会遗留有少量甲醛，并逐渐释放。这种气味对人体极为有害。 在选购时，可从气味来判断，因为气味越大，说明甲醛释放量越高，污染越厉害，其危害性就越大。

5. The smell should be light. The adhesive used for decorative panels is mainly urea formaldehyde resin. After * treatment, a small amount of formaldehyde will be left in the material and gradually released. This smell is extremely harmful to human body. When purchasing, you can judge from the smell, because the greater the smell, the higher the formaldehyde emission, the more serious the pollution, and the greater the harm.

6、注意含水率。通常装饰单版贴面胶合板要求有一定的含水率，其含水率越接近使用地区的平衡含水率越好。 含水率过高或过低，装饰板都会在环境温度变化影响下出现较大的变形。因此，在温度比较小的地区，适宜使用含水率较低的装饰板；反之，则应使用含水率较高的装饰板。

6. Pay attention to moisture content. Generally, decorative veneer plywood is required to have a certain moisture content. The closer its moisture content is to the equilibrium moisture content in the area of use, the better. If the moisture content is too high or too low, the decorative plate will be greatly deformed under the influence of ambient temperature changes. Therefore, in areas with low temperature, it is suitable to use decorative panels with low moisture content; On the contrary, the decorative board with high moisture content shall be used.

7、观察纹理结构。在其他项都满意的情况下，还要注意材质应细致均匀、色泽清晰、木纹美观。配板与拼花的纹理应按一定规律排列，且木色相近，无明显色差，拼缝与板边近乎平行。这样的板材才能收到很好的装饰效果。

7. Observe the texture structure. When other items are satisfactory, it should also be noted that the material should be fine and uniform, the color should be clear and the wood grain should be beautiful. The texture of matching plate and parquet shall be arranged according to certain rules, and the wood color is similar without obvious color difference, and the parquet joint is almost parallel to the plate edge. Such a plate can receive a good decorative effect.
