杭州市耐火材料耐火完整性检测

盐城市防火门耐火时间测试中心：防火门UL认证 – UL认证简述 UL认证是为市场得到具有相当安全水准的商品，为人身健康和财产安全得到保证作出贡献。就产品安全认证作为消除国际贸易技术壁垒的有效手段而言，UL为促进国际贸易的发展也发挥着积极的作用。 防火门UL认证 – UL 10B－标准名称：UL 10B Fire Test of Door AssembliesUL 10B 针对门系统结构的防火测试防火门UL认证 – UL 10B－涵盖范围：- These methods of fire tests are applicable to door assemblies of various materials and types of construction for use in wall openings to retard the passage of fire- Tests made in conformity with these test methods register performance during the test exposure; and such tests shall not be construed as determining compliance for use after exposure to fire- It is the intent that tests made in conformity with these test methods develop data to enable regulatory bodies to determine the compliance of door assemblies for use in locations where fire resistance of a specified duration is re These methods are intended to evaluate the ability of a door assembly to remain in an opening during a predetermined test exposure- The tests expose a specimen to a standard fire exposure controlled to achieve specified temperatures throughout a specified time period, followed by the application of a specified standard fire hose stream. The exposure, however, is not representative of all fire conditions, which vary with changes in the amount, nature, and distribution of fire loading, ventilation, compartment size and configuration, and heat sink characteristics of the compartment. It does, however, provide a relative measure of fire performance of door assemblies under these specified fire exposure conditions.铝单板和铝塑板的产品对比　　项目 2.5mm铝单板 4mm厚的铝塑复合板　　外观质量　　前者：平板平整度不高，看上去有局部凹凸，但可以加工成各种不规则形状; 喷涂 辊涂质量，眼观质量好，色差和膜厚偏差，和膜厚偏差;局部损坏可以修补。　　后者：平板平整度比较高，但加工型状受限;由于人工技术的不稳定，有局部色差 不明显，但损坏不可局部修补。　　2、机抗拉强度 130/mm 38-61N/mm2X　　3、机械伸长度 5%-10% 12%-17%　　4、折弯强度 84.2N/mm 34N/mm2　　5、能弹性模量 70.00N/mm2 26.136-49.050N/mm2　　从上表可以看出，铝单板的外观比铝塑板差一些，但是其机械性能明显优于铝塑板，其抗风压性能也优于铝塑板。但是在我国大部地区，其风压值铝塑板是完全可以承受，所以，工程使用铝单板有点大材小用。
