Description

防漏电与防电磁辐射电热地膜及其制作方法
技术领域:
本发明涉及一种建筑物内取暖设施,具体涉及一种防漏电与防电磁辐射电热地膜及其制作方法。
背景技术:
目前建筑物室内取暖主要是采用水、气取暖和电力取暖两大类,而水、气取暖需要在室内外铺设供热管路和加热锅炉等大型设备,一次性投资较大,需要常年维护,而且温度不易单独控制,需要额外安装散热器,将占用室内有限的使用面积,也为室内装饰造成困难。电取暖明显优于水、气管网取暖,具有投资少,维护简单,控温容易等优点,但是目前电取暖除各种可移动的电暖装置外,其非移动的电暖装置是采取膜片结构,电热膜固定在墙壁和天棚上,这种取暖也给装饰造成不便,而且天棚取暖使室内上部温度较高,感觉不适。但同时,电取暖也带来了很多的问题,电加热地膜存在的问题主要有: ( 1 )存在由于分布电容而引起的电流泄漏,当现场敷设面积较大时易引起漏电保护器动作; ( 2 )在使用时易引起电场辐射。而目前市场上的电热膜均没有足够的防护措施以克服电流泄漏与电场辐射,使得电地热取暖存在隐患,严重时甚至会影响人们身体健康及生命安全。
发明内容:
本发明的目的是针对上述存在的问题提供一种防漏电与防电磁辐射电热地膜及其制作方法,具有散热效果好,有很好的防漏电性,舒适度高,便于地面铺设的电热地膜。
上述的目的通过以下的技术方案实现:
防漏电与防电磁辐射电热地膜,其组成包括:一组电热膜片单元,所述的电热膜片单元由两层或者两层以上聚脂薄膜粘合而成,在粘合面上两侧边沿处具有通过银浆印制的导电极,所述的两侧的导电极分别连接导线,所述的两侧的导电极之间连接均匀分布的油墨导电条,所述的聚脂薄膜外面两侧分别具有导电铝箔带,所述的导电铝箔带连接零线电极,所述的导电铝箔带外侧具有PE封套,所述的PE封套外侧具有PVC保护封套,所述的导线连接供电电源,所述的电热膜片的功率密度为每平方米160-320w,所产生的远红外线的主流波在8-14微米之间。
一种防漏电与防电磁辐射电热地膜的制造方法:该方法包括如下步骤:
(1)通过印刷工序将发热体即油墨导电条印刷在聚酯薄膜上,再通过印刷工序将两侧接触导电极通过银浆印刷在聚酯薄膜的两侧形成基膜即电热膜片单元主体,所述的电热膜片的功率密度为每平方米160-320w,所产生的远红外线的主流波仔8-14微米之间;
(2)通过复合工序在所述的基膜上复合一层附有热固胶的聚酯薄膜及导线;
(3)通过复合工序将附有热固胶的导电铝箔带复合于聚酯薄膜的外侧,并将零线电极接于导电铝箔接地带上;
(4)通过封装工序封装上PE封套和PVC保护封套。
有益效果:
1、节能环保:电热地膜相对于天棚膜和墙膜更接近于人体,使得电热膜发出的热量得到充分有效利用;作为低温辐射电热膜其电热转换效率近100%,还有自主调温自动控制的功能,用电量易计量,节约归已,使用者易建立行为节能的意识,避免了不必要的浪费。
电热膜是直接将清洁能源电力转换为热能的采暖设施,充分体现出电热膜的环保性能。
2、舒适保健:电热地膜采暖符合人体对采暖的需要,足暖头凉,且为大面积低温辐射供热,使得地面温度较低且温度场均匀,与传统对流式的采暖方式相比,室内无热气流流动,会减少浮尘和空气干燥,使人感觉舒适。另外,电热膜所产生的远红外热射线的主流波在8-14微米之间,以9.5微米通量居多,这被认为是对人和植物生长最为有益的波段,也被形象地称为“生命之光”,所以其保健作用也显而易见。
3、适用范围:电热膜工作电源既可用交也适用直流电源,电源电压从90-300V,功率密度从每平方米160-320W,这些都为电热膜的应用提供了一个宽广的范围。
4、安全可靠:国外应用电热膜应有已有三、四十年的历史,但至今也仍局限安装于棚面或墙面,尚未有安装于水泥地面下的即电热地膜产品问世。电热地膜采暖是将电热膜埋于地面下,实现地面辐射采暖的功能,其技术关键在于防水、绝缘、防漏电、防电磁辐射等技术。因为地面在施工及使用过程中都会潮湿的问题,良好的防水和高强的绝缘是必须的;其二,因为是埋于地面下,电热膜与地面间会由于结构特性产生微弱电容,在交流电下,就会产生电流,该电流从电热膜导向地面,形成漏电电流,当然足够大时,会使供电***的漏电保护器动作,而无法正常工作;其三,由于是电热地膜采暖其电热元件更靠近人体,防止电磁场辐射也须考虑其内。
本专利的电热地膜采用整体双重绝缘双重防水,安装有接地故障保护、漏电回收及防电磁辐射等措施。电热地膜采暖***采用双重绝缘双重防水且附有漏电防护、电磁屏蔽等多项设计。其在防电击等级上达到国标Ⅱ类电器水平。电磁防护达到国标一级标准,在这种环境下长期居住、工作和生活的一切人群(包括婴儿、孕妇和老弱病残者),其健康不受影响。其防水等级超过国标IPX7;潮态绝缘电阻可达100MΩ以上。
5、安装方便:电热地膜,集成化高,在现场只需做简单的插头连接。这不仅简化了施工工艺,对施工人员也无需特别要求,这将大大提高施工效率并减少了人员成本。

附图1是每个电热膜片单元的结构示意图。
