防火门的目的是为了在遇上火灾时起到阻止火情蔓延的效果,钢制防火门由耐火钢板复合压制而成,钢板中间填充硅酸铝棉等耐火材料。防火门事关生命财产的安全,必须严格控制,那么怎么知道一家钢质防火门厂家的质量好坏呢?防火门防火性体现在耐火完整性、隔热性、稳定性上,这主要由门体结构和严密和科学,以及门内充填物的防火性来提供和保证。钢质防火门厂家的产品材料要好,并严格按加工规范进行生产:门框、门扇的板材应当采用是优质钢板制作,且厚度要足,表面要完好无凹凸、擦痕等;门本身和各个配件的耐火指标必须达到相应耐火级别的要求;需要焊接的部位必须要保证牢固不易松脱,并且要打磨平整光滑;门扇的表面应喷漆进行防锈处理。现在钢质防火门厂家在生产时已普遍以热压取代以往的冷压工艺,不仅效率提高,缩短了工时,且门扇的平整度和整体强度也得到提高,自然其耐火性能也提高了。 本文地址:http://dlhfmc.com 154.
