阻燃整理 - 搜狗百科 ...... UV整理主要是后整理時上了紫外線吸收劑阻燃可以是后整理上阻燃劑,也可以在紡絲時阻燃.

阻燃材料阻燃的原理是什么呢? ...... 3、通過分散燃燒物的熱量和稀釋燃燒物質來達到阻燃效果.

阻燃布是怎樣進行后整理加工的呢? - ...... 阻燃布的阻燃效果評估基本上都是先將阻燃布點燃燃燒(或置于火焰中)一段時間,當面料遠離火焰后,評估其燃燒難易程度和火焰的傳播速度;還要進行斷裂強力和撕破強力測試,以及面料的PH值和甲醛含量.綜合上面的各個檢測數據后,才能判斷阻燃布的產品質量是否過關.(新科特種紡織)

防火涂料阻燃的基本原理有哪些 - ...... 1.膨脹型防火涂料:涂層遇火膨脹形成隔熱層,同時釋放阻燃氣體降低燃燒程度.2.非膨脹型防火涂料,依靠自身低導熱性能,阻止溫度快速上升.起到防火的作用.

織物阻燃機理是什么 - ...... 阻燃體現在兩個方面:一是材料具有隔熱性;二是材料本身耐高溫.

什么是牛仔布阻燃整理? ...... 牛仔布大多數為纖維素纖維,作為有機高分子化合物很容易燃燒.對其進行阻燃整 理可使牛仔布具有不易燃燒,或燃燒后離開火源能自動熄滅的效果.阻燃整理是利用阻燃 劑隔絕空氣、火源和可燃性氣體;或阻燃劑在遇火后分解成不燃性氣體,沖淡和降低可燃性 氣體,使之不燃燒;或用阻燃劑吸熱,抑制熱量的釋放,使纖維的溫度降至燃燒溫度以下而不 再燃燒.另外有些阻燃劑可改變纖維素的熱分解過程,增加炭化物的形成,減少可燃性揮發 物的生成以控制纖維素的燃燒.
