            永记——钢结构防火涂料的检查方法

            [图文] 2015-06-02

             

            永记-钢结构防火涂料的检查方法:
            1.可在?#27542;?#23545;产品的质量作一初步的检查:在已施工好的基材上切取2~3块小样,或取少量样品涂在2~3块150mm×150mm胶合板上,按实际施工的情况涂刷。待干透后,用酒精灯的火焰检查。火焰高度40mm左右,施加火焰的时间?#35805;?#20026;20min,检查涂层发泡情况。正常的情况下,按规定的用量(?#35805;?#20026;500克/平方米)施工,一级防火涂料的泡层厚度为20mm以上,二级防火涂料的泡层厚度为10mm以上泡层应均匀致密。
            2.合格防火涂料在受到喷灯等强火灼烧?#20445;?#20250;大量发泡膨胀,表面聚集凸起,数分钟内不会出现烧损现象,而假冒伪劣防火涂料则基本?#29615;?#27873;,会出现大?#21487;?#33853;掉渣的情况,木质基材也会很快发生燃烧破损?#21335;?#35937;。
            3.查验该产品是否具有国家级消防质检中心出具的合格检验报告,?#37096;?#19978;网查询。防火涂料实行消防产品型式认可制度,市场上销售的防火涂料应具备国家消防产品型式认可证书和型式检验合格报告。
            4.在实际使用中,为了保证防火涂料的防火及其他使用性能,?#35805;?#38656;要采用透明的?#32622;?#28034;层。防火涂料的用量?#35805;?#20026;350~500克/平方米,?#32622;?#28034;层的用量?#35805;?#20026;50克/平方米。
            5.根据国家标准,除满足阻火性要求外,防火涂料的燃烧性能分为一级和二级。在规定的实验条件下,一级防火涂料的耐?#38469;?#38388;不小于20分钟,二级防火涂料的耐热时间不小于10分钟。用户在选择时应注意?#21491;?#21306;别,避免企业以次充好,达不到防火保护效果。
