Description

一种静电除尘纱窗及其制备方法和应用
技术领域
本发明属于新材料技术以及环保技术领域，具体涉及一种静电除尘纱窗及其制备方法和应用。
背景技术
静电除尘是气体除尘方法的一种，主要是利用高压静电场吸附的原理去除空气中的颗粒物，如灰尘、煤烟、花粉等，同时还可以有效吸附空气中的气态污染物及过滤空气中的致病微生物等。通常地，含尘气体经过高压静电场时被电分离，尘粒与负离子结合带上负电后，趋向阳极表面放电而沉积。利用静电场使气体电离从而使尘粒带电吸附到电极上的收尘方法。在强电场中空气分子被电离为正离子和电子，电子奔向正极过程中遇到尘粒，使尘粒带负电吸附到正极被收集。目前，静电除尘通常采用40kV以上的直流高压电场，虽然除尘效率高，但也存在耗能大、容易产生臭氧等弊端，尤其在室内除尘应用中具有高危险性。因此，开发一种节能、环保、安全性能高的室内除尘技术具有重要的应用价值和现实意义。

进一步的，所述步骤(2)中二氧化钛的质量浓度为0.2%~1.5%。
进一步的，所述步骤(3)中静电纺丝技术采用的电压为10~15kV，喷头到铝箔的距离为100~150毫米，滚轴转速为80~100转/分钟，针头喷射速度为0.08~0.12毫米/分钟。
