3. The relative humidity of the property of interior decoration products and roof fire-proof board decoration products shall not exceed 70% relative humidity at - 30 ℃ 15 ℃ of the installation space for normal use. All gypsum, cement, terrazzo or other wet properties of the project must be properly placed. Before or after installation, the heating, ventilation and cooling air conditioning system must be installed first and can be used properly to maintain normal temperature.

　　4、不建議用絕緣材料覆蓋或支撐天花板。在相對濕度較高的情況下，如果天花板承受額外的重量，可能會導(dǎo)致天花板下沉。本工程需要保溫材料時，必須在正常使用環(huán)境下使用，保溫材料重量不超過1.269kg/m2，只能使用線圈保溫材料。必須垂直安裝在框架的支點上，以支撐隔熱材料的重量。

　　4. Covering or supporting the ceiling with insulation is not recommended. In the case of high relative humidity, if the ceiling bears additional weight, it may cause the ceiling to sink. When insulation materials are needed in this project, they must be used in normal use environment. The weight of thermal insulation materials shall not exceed 1.269kg/m2, and only coil insulation materials can be used. It must be mounted vertically on the fulcrum of the frame to support the weight of the insulation.

　　5、防火板的保養(yǎng)與一般油漆天花板相似，但需要保養(yǎng)，為了保護(hù)天花板的高性能、果和美觀外觀，請按規(guī)定做法處理。 灰塵或松散的泥土要用刷子或真空吸塵器清潔，真空吸塵器配件，應(yīng)用于清潔窗簾布料或墻面類，必須單向清潔，以免灰塵摩擦到天花板表面。 清潔后的灰塵，如鉛羊毛標(biāo)志，臟點，或附著的污垢可以用一般的藝術(shù)膠清除，如用高品質(zhì)的墻壁清潔劑擦拭，海綿在水中試圖擠干，擦拭后，薄觸清潔劑可用洗碗布或少許濕用水海綿再次清洗。

　　5. The maintenance of the fireproof board is similar to that of the common painted ceiling, but it needs to be maintained. In order to protect the high performance, high effect and beautiful appearance of the ceiling, please handle it according to the regulations. Dust or loose soil should be cleaned by brush or vacuum cleaner. Vacuum cleaner accessories should be used to clean curtain cloth or wall surface. One way cleaning is required to avoid dust rubbing on ceiling surface. After cleaning, the dust, such as lead wool sign, dirty spot, or attached dirt, can be removed with general art glue. For example, wipe with high-quality wall cleaner. Sponge tries to squeeze dry in water. After wiping, clean it again with dishcloth or a little wet water sponge.

　　以上就是防火板的日常保養(yǎng)方法，希望可以幫到大家。
