Abstract:

为揭示冲洗水流经丙纶、涤纶集尘极表面浸入扩散过程的一般规律,解决传统湿式静电技术由集尘极材料选择及表面水膜布置不均引发的系列问题,利用高速摄像系统测量不同体积和性质的液滴在丙纶纤维织物(840A)和涤纶纤维织物(728)表面扩散面积和液滴高度随时间的变化关系,得到液滴浸入扩散动力学特性。结果表明:水液滴与840A的接触角θ为136.2°,与728的θ为52.5°,乙醇液滴与840A的θ为41.9°,与728的θ为46.5°;液滴扩散可分为扩散初期和后期两个阶段;水、乙醇液滴在728表面的扩散形状均为椭圆,扩散过程分别符合ExpAssoc、Hill分布;水、乙醇液滴在840A表面的扩散形状为圆和椭圆,乙醇液滴扩散过程符合Hill分布;织物表面纹理结构、液滴体积和性质、织物厚度、材料表面自由能对液滴扩散过程有明显影响。
