Grade fireproof board:

級防火板有下面幾種情況：

There are several situations for grade fireproof boards:

A 級： 不燃性建筑材料：幾乎不發(fā)生燃燒的材料。

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

A1級：不燃，不起明火。

A1 level: non combustible, no open flames.

A2級：不燃，要測量煙，要合格。

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

在我們這個裝飾行業(yè)中一般A級指的是A2級不燃，要測量煙，要合格，看自己配合什么基材，主要是看你自己的基材，基材可以達到就可以達到相應的板材，一般在我們裝飾表面層建材行業(yè)中一般都是貼基材可以做到A2級，不過比較少人使用這款基材。

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.

級防火板：

Grade fireproof board:

指的是難燃性建筑材料：難燃類材料有較好的阻燃作用，其在空氣中遇明火或在高溫作用下難起火，不易很快發(fā)生蔓延，且當火源移開后燃燒立即停止，因其板材在生產的時候可以加入阻燃劑，是非常輕松就可以做到b1級效果的，一般客戶使用的都是這種材料較多。

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.

這些就是這兩款材料的區(qū)別，一般裝飾公司使用b1級的防火板就夠了，這個是行業(yè)中的標準，不管是家具還是墻面或者是其他的一些公共裝飾區(qū)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.
