Grade fireproof board:

级防火板有下面几种情况：

There are several situations for grade fireproof boards:

A 级： 不燃性建筑材料：几乎不发生燃烧的材料。

Class A: Non combustible building materials: Materials that almost do not burn.

A1级：不燃，不起明火。

A1 level: non combustible, no open flames.

A2级：不燃，要测量烟，要合格。

A2 level: non combustible, smoke must be measured and qualified.

在我们这个装饰行业中一般A级指的是A2级不燃，要测量烟，要合格，看自己配合什么基材，主要是看你自己的基材，基材可以达到就可以达到相应的板材，一般在我们装饰表面层建材行业中一般都是贴基材可以做到A2级，不过比较少人使用这款基材。

In our decoration industry, A grade generally refers to A2 grade non combustible. To measure smoke, it is necessary to be qualified, and it depends on what substrate you match. It mainly depends on your own substrate, which can reach the corresponding board. In our decoration surface layer building materials industry, A2 grade can be achieved by sticking the substrate, but it is relatively rare to use this substrate.

级防火板：

Grade fireproof board:

指的是难燃性建筑材料：难燃类材料有较好的阻燃作用，其在空气中遇明火或在高温作用下难起火，不易很快发生蔓延，且当火源移开后燃烧立即停止，因其板材在生产的时候可以加入阻燃剂，是非常轻松就可以做到b1级效果的，一般客户使用的都是这种材料较多。

Refers to non combustible building materials: Non combustible materials have good flame retardancy, and they are difficult to ignite when exposed to open flames in the air or at high temperatures, making it difficult to spread quickly. Moreover, when the fire source is removed, combustion immediately stops. As flame retardants can be added to the board during production, it is very easy to achieve a b1 grade effect. Generally, customers use this type of material more frequently.

这些就是这两款材料的区别，一般装饰公司使用b1级的防火板就够了，这个是行业中的标准，不管是家具还是墙面或者是其他的一些公共装饰区域。

These are the differences between these two materials. Generally, decoration companies use b1 grade fireproof boards, which is a standard in the industry, whether it is furniture, walls, or other public decoration areas.
