产品详情

  1.适用范围

      适用于表面具有绒毛(列如起绒.毛圈簇绒或类似表面)的纺织织物,表面燃烧时间的测定。

  2.符合标准

   符合GB/T8745-2001《纺织品.燃烧性能织物表面燃烧时间的测定》,ISO10047 : 1993试验标准

  3.原理:

在规定的试验条件下,在接近顶部处点燃夹持于垂直板上的干燥试样的起绒表面,测定火焰在织物表面向下蔓延,尔不易向上蔓延,这是因为燃烧产物的覆盖作用,使火焰上方的绒毛不易燃烧。

  4.技术参数:

  4.1 试验箱:尺寸:长767mm×宽300mm×高300mm用不锈钢制成

  4.2  试样夹持器:由150长,宽75mm和3mm厚的不锈钢板及3mm厚的不锈钢框

架组成,使露出的受试织物表面为125mm×50mm。框架上应有标记线,其位于试样点火初下方25mm的位置上

  4.3 燃烧器

  4.3.1  气体喷嘴口径0.19mm±0.02mm

  4.3.2  点火管由四部分组成:空气管,气体混合区、扩散区、气体出口。

  4.4.3  火焰稳定器

  4.4  气体:工业用丁烷或丙烷

  4.5  刷毛装置

  4.6  干燥器

  4.7  计时器0~99.99s任意设定,精度:1S/H

  4.8  标尺:分辨率:1.0mm
