折叠式静电纤维的吸附性能测定

The Determination on the Adsorptivity of the Folding Electrostatic Fiber

为了解折叠式静电纤维过滤材料对空气中ＩＰ、ＣＯ的吸附能力，选择５家工厂生产的７种折叠式静电纤维无纺布作为吸附材料，采用小室试验的方法，测定其对ＩＰ（≤１μｍ）、ＣＯ的吸附能力。结果表明，折叠式静电纤维对ＩＰ、ＣＯ吸附效率６０分钟内最高达６０．７％和４１．２％，最低为２４．１％和７％。实验证明，折叠式静电纤维对ＩＰ具有较好的吸附能力，对ＣＯ的吸附效果不尽人意。可以认为，该材料能够有效地减低空气中ＩＰ浓度，是一种较为理想的去除可吸入颗粒物的过滤材料。

kinds of the folding electrostatic fiber(FEF) made by 5 factories were selected to determine their adsorptivity to IP (≤1μm) and CO in the air of the cupboard with volumn of 1 36m 3 The results showed that the adsorption rates of FEF to IP and CO reached 60.7% and 41.2% respectively at most,as well as 24 1% and 7% respectively at least within 60 minutes.It indicated that the adsorptive efficiency of FEF to IP was perfcet,while to CO was not satisfying.So the FEF might be thought as a good filtering material to effectively clean IP and decline its concentration in the air.
