Fumeijia fire-proof board: the variety of construction board is complex. According to its combustion function, it can be divided into four categories: non combustion data (a), fire-resistant data (B, class), combustible data (c), combustible data (d). After all, the materials of fire-proof board and table top shall not burn. The incombustibility test in accordance with GB / t5464-85 shall be carried out according to the following conditions, otherwise it shall be regarded as data (or class a data):

　　(1)由于数据触痛，炉内温升均匀不超过50℃;

　　(1) Due to data tenderness, the temperature rise in the furnace is not more than 50 ℃;(2)样品均匀连续燃烧时间不超过20s;

　　(2) The uniform continuous combustion time of the sample shall not exceed 20s;(3)样品均匀失重率不超过50%

　　(3) The uniform weight loss rate of the sample shall not exceed 50%有些无机板(如镁质水泥)，虽然本身不烧糊，但在大火的高效化作用下，很容易断裂，失去结构强度，有些可能会释放出更多的有毒气体。因此，这些板材还不能用作防火板台面材料。这是我们防火板台面材料作为防火应用的基本要求的地方。防火板台面施工关键要记住:

　　Some inorganic plates (such as magnesia cement) are easy to break and lose structural strength under the effect of high efficiency of fire, although they do not burn themselves. Some of them may release the most toxic gases. Therefore, these plates can not be used as the materials of fire-proof board table. This is the place where our fireproof board top material is the basic requirement of fireproof application. The key points in the construction of fire-proof board and table top shall be kept in mind:

　　(1)薄层防火涂料可根据装修要求和涂料性能选择喷涂、涂刷或辊涂等施工方法。

　　(1) According to the decoration requirements and coating performance, the construction methods of spraying, brushing or roller coating can be selected.

　　(2)薄层防火涂料的涂层厚度每次不应超过2.5mm，超薄层防火涂料的涂层厚度每次不应超过0.5mm。必须在前一次干操作后施工。

　　(2) The coating thickness of thin layer fire retardant coating shall not exceed 2.5mm each time, and that of ultra thin layer fire retardant coating shall not exceed 0.5mm each time. It must be constructed after the previous dry operation.

　　(3)厚层防火涂料可选择喷涂或工艺改变结构。

　　(3) The thick layer fire retardant coating can be sprayed or the process can change the structure.

　　(4)防火涂料厚宜采用低速搅拌机搅拌，搅拌时间不宜过长，搅拌均匀，以免猜测轻骨料是过于粉化的涂料质量。

　　(4) The thickness of the fire retardant coating should be stirred by a low-speed mixer, and the mixing time should not be too long, and the mixing should be even, so as to avoid guessing that the light aggregate is too powdered coating quality.

　　(5)厚层防火涂料每次改性厚度应在5-10mm之间，施工前或施工后需将涂料烘干。

　　(5) The modified thickness of thick fire retardant coating shall be between 5-10 mm each time, and the coating shall be dried before or after construction.

　　(6)水泥厚防火涂料在极端干燥天气和阳光直射环境下应采取必要的养护措施。

　　(6) Necessary curing measures shall be taken for cement thick fireproof coating in extremely dry weather and direct sunlight environment.

　　(7)调配好防火涂料后应及时用完，超过规定的使用期限不能使用。

　　(7) After the fire retardant coating is prepared, it shall be used up in time and cannot be used beyond the specified service life.

　　(8)防火涂料的厚度应符合设计要求，施工过程中应随时检测防火涂料的厚度。

　　(8) The thickness of fireproof coating shall meet the design requirements, and the thickness of fireproof coating shall be tested at any time during construction.
