钢结构防火涂料的选型主要存在的问题

发布时间:2015-12-9 9:35:19 浏览次数:584

   一是超薄型钢结构防火涂料已经成为我国钢结构防火涂料的研究和生产单位竞相研制的热点,超薄型钢结构防火涂料一般为溶剂型体系,由于与厚型和薄涂型钢结构防火涂料相比,超薄型钢结构防火涂料装饰性更好,涂层更薄,工程中使用量大大减少,从而降低了工程总费用,是目前市场上大力推广的品种。


    但是,在钢结构防火保护工程中出现了片面的追求涂层越来越薄的现象,片面的宣传推广超薄型涂料的现象,这对为建筑物提供切实可靠的安全保障极为不利。由于超薄型钢结构防火涂料主要还是依靠配方中有机成分的物理化学反应起作用,任何影响涂料炭化膨胀性质的因素都将影响其最终的防火性能,很难保证在涂装较长时间后还能为构件提供2.0h以上的防火保护。


    二是设计者往往是简单的注明采用钢结构防火涂料保护措施,不能详细的说明选用哪一种类型的钢结构防火涂料,在施工中单纯考虑价格、美观等问题,造成防火涂料选型不当的现象。


   三是选型时往往忽视建筑物的环境以及使用性质的要求。露天钢结构受到日晒雨淋,或高层建筑的顶层钢结构上部采用透光板时,阳光暴晒,环境条件较为苛刻,应选用室外型钢结构防火涂料。四是把技术性能仅满足室内要求的涂料用于室外。

 

One is a thin steel structure fire retardant coating has become a hot research and production units in our country, the thin steel structure fireproof coating is generally solvent system, due to the thick and thin coated steel structure fire retardant coating, the coating is better, the coating is more thin, the use of the project is greatly reduced, thereby reducing the total cost of the project, is currently on the market to promote varieties.
However, in the steel structure fire protection engineering, there is a one-sided pursuit of the phenomenon of thin coating, one-sided propaganda to promote the phenomenon of ultra-thin coatings, which is very bad for the protection of buildings to provide practical and reliable. Because the ultra thin steel structure fireproof coating mainly depends on the physical and chemical reaction of the organic components in the formulation, any factors that affect the properties of the coating can affect the final fire performance, it is very difficult to guarantee the fire protection of 2.0h over the long time after coating.
Two is the designer is often simple to specify the use of steel structure fire protection measures, can not explain in detail the use of which type of steel structure fireproof paint, in the construction of pure consideration price, appearance and other issues, resulting in the selection of fire retardant coating phenomenon.
Three is the selection of the environment and the neglect of the building environment and the use of the nature of the requirements. Open steel structure under the sun and rain, the upper part of the top steel structure or high-rise building adopts transparent plates, sun exposure, environmental conditions, should be used in outdoor fire retardant coatings for steel structures. Four is to meet the technical performance of the indoor requirements of paint for outdoor.
