实验研究了相对湿度对ePT FE 高效空气过滤材料阻力的影响，并与玻璃纤维高效滤料作对比。结果表明：相对湿度对ePT FE 和玻纤高效滤料的初阻力没有影响。过滤固态气溶胶时，ePT FE 滤料在表面过滤阶段的阻力呈线性增长，但增长速度高于相同湿度下的玻纤滤料；过滤液态气溶胶时，ePT FE 滤料早于玻纤滤料进入阻力指数增长阶段，两种滤料的容尘性能存在显著差异。

A n experim entalstudy on the influence ofrelative hum idity on resistance ofePTFE high efficiency airfilter m edium , and com pared the results to glass fiber high efficiency air filter m edium . T he results show that, relative hum idity has no significant influence on the initial resistance of both ePT FE and glass fiber filter m edium . W hen challenged by solid aerosol,the resistance ofePTFE filterm edium in the stage ofsurface filtration increaseslinearly but fasterthan thatofglassfiberfilterm edium .W hen challenged by liquid aerosol,the resistance ofePTFE filterm edium enters exponential increase earlier than glass fiber, leading to significant difference in capacity perform ance betw een these tw o kinds of filter m edium .
