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)由于數(shù)據(jù)觸痛，爐內(nèi)溫升均勻不超過50℃;

　　(1) Due to data tenderness, the temperature rise in the furnace is not more than 50 ℃;(2)樣品均勻連續(xù)燃燒時間不超過20s;

　　(2) The uniform continuous combustion time of the sample shall not exceed 20s;(3)樣品均勻失重率不超過50%

　　(3) The uniform weight loss rate of the sample shall not exceed 50%有些無機(jī)板(如鎂質(zhì)水泥)，雖然本身不燒糊，但在大火的高效化作用下，很容易斷裂，失去結(jié)構(gòu)強(qiáng)度，有些可能會釋放出更多的有毒氣體。因此，這些板材還不能用作防火板臺面材料。這是我們防火板臺面材料作為防火應(yīng)用的基本要求的地方。防火板臺面施工關(guān)鍵要記住:

　　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)薄層防火涂料可根據(jù)裝修要求和涂料性能選擇噴涂、涂刷或輥涂等施工方法。

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

　　(2)薄層防火涂料的涂層厚度每次不應(yīng)超過2.5mm，超薄層防火涂料的涂層厚度每次不應(yīng)超過0.5mm。必須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)厚層防火涂料可選擇噴涂或工藝改變結(jié)構(gòu)。

　　(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攪拌機(jī)攪拌，攪拌時間不宜過長，攪拌均勻，以免猜測輕骨料是過于粉化的涂料質(zhì)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)厚層防火涂料每次改性厚度應(yīng)在5-10mm之間，施工前或施工后需將涂料烘干。

　　(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)水泥厚防火涂料在極端干燥天氣和陽光直射環(huán)境下應(yīng)采取必要的養(yǎng)護(hù)措施。

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

　　(7)調(diào)配好防火涂料后應(yīng)及時用完，超過規(guī)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)防火涂料的厚度應(yīng)符合設(shè)計要求，施工過程中應(yīng)隨時檢測防火涂料的厚度。

　　(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.
