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 Assemblies
UL 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 c***truction 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 c***trued 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 locati*** where fire resistance of a specified duration is required.
- 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 conditi***, 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 conditi***.
铝单板和铝塑板的产品对比jsgf19310zjh
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。
