How to distinguish the quality of fireproof board1、查：查一下产品的各种标识，如是否正规厂家生产的商标、出厂合格证、生产地址售后服务电话、防伪标志、环境标志、甲醛释放量和胶合强度值等。

　　1. Check: check all kinds of marks of the products, such as the trademark produced by the regular manufacturer, factory certificate, production address, after-sales service telephone number, anti-counterfeiting label, environmental label, formaldehyde emission and bonding strength value, etc.

　　2、闻：用鼻孔贴进材闻一下，如果细木工板散发清香的气味，说明甲醛含量较低，如果气味刺鼻则说明甲醛含量较高。

　　2. Smell: stick the material into the nostrils to smell it. If the blockboard gives off a fragrant smell, it indicates that the formaldehyde content is low; if the smell is pungent, it indicates that the formaldehyde content is high.

　　3、摸：用手触摸一下细木工板、集成材和多层板表面，优质的板应手感干燥，平整光滑，横向触摸无波浪形，说明含水率低，平整度好。

　　3. Touch: touch the surface of blockboard, Glulam and multilayer board by hand. The high-quality board should be dry, flat and smooth, and there should be no wave shape in the horizontal touch, indicating that the moisture content is low and the flatness is good.
               

　　4、看：质量上乘的防火板表面应当光滑平整，无缺陷，从侧面看板芯厚度是否均匀，细木工板和多层板则要观察有无重叠离芯现象。

　　4. Look: the surface of high-quality fireproof board should be smooth and flat, without defects. From the side, see whether the thickness of the board core is uniform, and whether there is overlap and separation from the core of blockboard and multilayer board should be observed.

　　防火板以密度板做基板为。可以保持防火板板长久的平整光滑性。一般一叠防火板纹理毫无区别的多是人造木皮贴面，染色的木皮，只需在挑选时，蘸点水，轻轻摩擦一下，掉色的即是染色的；天然木皮贴面板美观大方，每一张板纹理不尽一致，但是却美的自然，不一样的得体。

　　Density board is the best choice for fireproof board. It can keep the smoothness of fireproof board for a long time. Generally, there is no difference in the texture of a stack of fire-proof boards. For dyed veneers, dip in some water and rub them gently, and the discolored ones are dyed; the natural veneers are beautiful and generous, and each board has different textures, but they are beautiful and natural, and they are not the same.
