Description

一种PTFE纤维覆膜耐高温针刺毡
技术领域
本发明涉及针刺毡技术领域，尤其涉及一种PTFE纤维覆膜耐高温针刺毡。
背景技术
目前，在一些烟尘过滤温度较低的场合，如炼铁厂、垃圾焚烧厂、高炉煤气厂等使用的过滤材料，其热稳定性、耐化学气体腐蚀性、过滤精度较差，滤料的使用寿命很低，为此有人设计出了使用多层材料复合的针刺毡，虽然具有一定的耐高温效果，但是各层之间的连接不稳定，容易分层脱落，结构强度差。
发明内容
本发明的目的是为了解决现有技术中存在理化性能差、易分层的缺点，而提出的一种PTFE纤维覆膜耐高温针刺毡。
为了实现上述目的，本发明采用了如下技术方案：
设计一种PTFE纤维覆膜耐高温针刺毡，包括基础层，所述基础层的上下面均连接有隔热层，所述隔热层远离基础层的一面均连接有PTFE纤维覆膜，所述PTFE纤维覆膜上均布有散热板，所述散热板上等距设有条形的散热槽，所述散热板靠近隔热层的一面连接有连接座，所述基础层上穿插有多条连接带，所述连接带交错穿过基础层两面的连接座。
优选的，所述基础层的内部设有与之平行的加强层，所述加强层为铁丝网或尼龙网。
优选的，所述隔热层内均布有长方体状的隔热槽。
优选的，所述散热板为铜质板，所述连接带为铝合金条。
优选的，所述隔热层为耐高温隔热棉。
本发明提出的一种PTFE纤维覆膜耐高温针刺毡，有益效果在于：本发明设置了PTFE纤维覆膜作为外部保护层，有效提高了针刺毡的耐腐蚀、耐高温能力，同时设置了隔热层对内部进行隔热保护，另外还设置了交错的连接带用于增加各层之间连接的紧密性，有效避免分层现象的发生，同时设置了散热板，增加了连接强度，并增加了散热效果。
附图说明
图1为本发明提出的一种PTFE纤维覆膜耐高温针刺毡的结构示意图。
图中：基础层1、加强层2、连接带3、隔热槽4、PTFE纤维覆膜5、散热板6、散热槽7、连接座8、隔热层9。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。
参照图1，一种PTFE纤维覆膜耐高温针刺毡，包括基础层1，基础层1的内部设有与之平行的加强层2，加强层2为铁丝网或尼龙网。基础层1的上下面均连接有隔热层9，隔热层9为耐高温隔热棉。隔热层9内均布有长方体状的隔热槽4。加强层2用于增加基础层1内部的结构强度，隔热层9用于隔绝外部与基础层1之间的热量传播，从而减少高温对隔热层9的破坏。
隔热层9远离基础层1的一面均连接有PTFE纤维覆膜5，PTFE纤维覆膜5上均布有散热板6，散热板6上等距设有条形的散热槽7，散热板6靠近隔热层9的一面连接有连接座8，基础层1上穿插有多条连接带3，连接带3交错穿过基础层1两面的连接座8。散热板6为铜质板，连接带3为铝合金条。PTFE纤维覆膜5起到高温保护以及耐腐蚀保护的作用，散热板6用于增加表面的散热效果同时提高表面的结构强度，避免热量积累对内部造成损害，散热槽7用于增加散热板6的表面积，提高散热效果，连接带3用于增加各层之间的连接强度，连接座8起到固定连接带3的作用。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
