木质防火门的阻燃处理工艺

发布日期:2018-11-05 作者:木质防火门 点击:

  木质防火门的阻燃处理工艺?木质防火门的阻燃质量联系到木质防火门的耐火极限,因而许多防火门出产企业都将该工序设立为出产进程中的特别进程控制点,可是由于阻燃工序缺少成熟的工艺规程,致使各个厂家的阻燃工艺各不相同,阻燃工艺不甚合理,无法确保阻燃质量,严重时导致防火门耐火极限下降,给人民群众的生命财产安全形成潜在的危险。现将木质防火门的阻燃工艺概括整理如下,以期讨论并恳请批评指正。

  木材的常用的阻燃方法有:喷涂法、浸泡法、蒸煮法、真空法、真空加压法等。喷涂法和浸泡法一般应用于不再进行刨削加工的木材外表,以及厚度低于10mm的薄板阻燃处理,不适用于木质防火门的出产。真空法和真空加压法虽然阻燃效果极佳,但因其设备贵重,在防火门出产企业中还未见使用。现在防火门丰亿彩票企业大多选用蒸煮法进行阻燃处理。在选用蒸煮法进行阻燃处理时应留意以下几点:

  1、待阻燃木材亦干不亦湿

  2、先阻燃剂后水再木材

  3、加盖阻燃,减少阻燃液的蒸腾速度

  4、常温出料

  许多防火门丰亿彩票出产厂家在木材阻燃进程中往往以时刻作为阻燃的规范,按照操作规程要求到达所需时刻,时刻一到就当即出料。这样使工人在操作进程中因工件太热不利于劳动保护,更重要的是,木材在由热变凉的进程中,木材内部的细胞因热胀冷缩而发生必定负压,被阻燃木材会在负压的效果下进一步吸收阻燃液,然后进步阻燃处理的质量。
