Abstract

多基布玻璃纤维针剌毡,涉及高温除尘过滤材料领域,是对现有的单基布玻璃纤维针剌毡的改进。它包括基布1、毡层2,其特征在于:它有一层以上的基布。它可提高玻璃纤维与基布的抱合力,从而提高玻璃纤维针剌毡的过滤性能和使用寿命。

Description

多基布玻璃纤维针刺毡
(一)技术领域:
多基布玻璃纤维针剌毡,涉及高温除尘过滤材料领域。是对现有的单基布玻璃纤维针剌毡的改进。
(二)背景技术:
现有的工业除尘用过滤材料,主要分为机织布和针剌毡两大类。针剌毡依据其所用原料不同,又有化学纤维针剌毡和玻璃纤维针刺毡之分。众所周知,化学纤维机械强度高、柔韧性好,但其弱点是耐高温性能差。所以,虽然在化学纤维针刺毡中纤维缠结性好,基布与毡的复合强度高,毡体密实,但它只能在130℃以下范围内使用。这致命的缺点大大缩小了它作为高温除尘用过滤材料的工业应用范围。而玻璃纤维作为无机材料,它具有优良的耐高温性能和化学稳定性,以它为原材料的玻璃纤维针剌毡,在高温除尘过滤材料领域得到了广泛的应用。但现有的玻璃纤维针剌毡,一般都是单基布结构,由于玻璃纤维外表光滑,纤维间抱合力差。在实际使用时,往往会出现“露底”现象。所谓“露底”,就是在玻璃纤维针刺毡的底面(基布面),可清楚地看到“基布”的存在。在实际使用中,毡面容易脱离基布,俗称“飞毡”。它不仅影响了玻璃纤维针刺毡的使用寿命,还限制了过滤风速的提高。
(三)发明内容:
本实用新型的目的在于:提出一种多基布玻璃纤维针剌毡。它可以提高玻璃纤维与基布的抱合力,从而提高玻璃纤维针刺毡的过滤性能和使用寿命。
本实用新型的技术解决方案如下:它包括基布1、毡层2,其特征在于:它有一层以上的基布1。毡层2与基布1相间放置。在玻璃纤维针刺毡中,基布是起机械支撑作用,多层基布的使用无疑增加了毡的机械强度。此外通过针剌机的作用,也增加了多毡层之间、多毡层与基布纤维之间的缠结密度,从而克服了玻璃纤维针剌毡原有的缺点。提高了它的过滤性能和使用寿命。
(四)附图说明:
图1为本实用新型结构示意图。
(五)具体实施方式:
面毡2-1、底毡2和两层基布1-1、1,均采用直径为6μ的80支无碱玻璃纤维纱。将短玻璃纤维通过梳理机梳理成100g/m2的玻璃纤维面毡2-1,与质量为100g/m2第一基布层1-1复合,将质量为200g/m2的底毡2,与400g/m2的第二层基布1复合。将两层毡和两层基布叠合在一起,通过针剌机两次针刺,再采用有机树脂体系对其表面进行化学处理,从而形成本发明的双层基布的,紧密而均匀的玻璃纤维针剌毡。该产品与单层基布玻璃纤维针刺毡产品主要性能对比如下:
    项  目     双基布毡     单基布毡
拉伸强度N/25mm 经向     1650     1375
纬向     1370     1320
透气率cm/s     22.6     28.2
透气率离散系数%     16.9     27
从上表中看出,本实用新型产品拉伸强度高,透气性均匀。大大提高了产品的使用寿命。
