微孔膜防水透湿织物热湿传递中织物表面凝结   总被引:5,自引:0,他引:5  
试制了一种织物微气候仪,模拟人体和服装之间的微气候,测量其中的温度和相对湿度。研究是否在织物里表面产生凝结,为进一步研究织物的热湿传递提供实验依据。测试装置由计算机控制,操作方便,实验时间短。本装置实验结果与ASTME96—00测试的透湿量相比较,对防水透湿织物的湿传递表征具有明显的优势。此外,本文从水蒸汽凝结和Kelvin公式,分析研究了微孔膜防水透湿织物热湿传递中发生表面凝结的现象。  相似文献

采用吸湿快干助剂HMW8870对纯棉织物进行吸湿快干整理,并通过测试纯棉织物的快干性、散湿性、透湿性、吸湿性以及毛细管效应来检验整理后织物吸湿快干性能。设计了3种不同的整理工艺和三因子三水平的正交试验。结果表明:经助剂HMW8870整理后的纯棉织物快干性和透湿性增加而吸湿性变化不大,其中HMW8870的浓度是主要影响因素,随着助剂浓度的增加整理后的织物水分蒸发率和透湿量增加,但当助剂浓度为50g/L时达到效果最好;氯化钠的浓度对织物的亲水性有一定的影响,当氯化钠浓度为20g/L效果达到最佳状态。  相似文献

By conformal mapping theory, a trigonometric interpolation method between odd and even sequences in rectangle boundary region was provided, and the conformal mapping function of rectangle-plate with arc radius between complicated region and unite dish region was carried out. Aiming at calculating the vibrating fundamental frequency of special-shaped, elastic simple-supported rectangle-plates, in the in-plane state of constant stress, the vibration function of this complicated plate was depicted by unit dish region. The coefficient of ftmdamental frequency was calculated. Whilst, taking simple-supported elastic rectangle-plates with arc radius as an example, the effects on fundamental frequency caused by the concentrated mass and position, the ratio of the length to width of rectangle, as well as the coefficient of constant in-plane stress were analyzed respectively.  相似文献

提高高强度结构钢板的残余应力的测试精度,可以更好地评估回火工艺的有效性,使产品更加安全可靠.常用的残余应力测试方法(如钻孔法、X射线衍射法等)只能测定钢板外表面及浅层的残余应力.采用裂纹柔度法分析回火钢板的残余应力,对Q550D钢板不同回火工艺状态下的应力松弛效果进行了测试.结果表明,裂纹柔度法能够测定钢板全厚度范围内残余应力释放过程中产生的应变,从而判断其应力分布情况,而且这种方法比钻孔法及X射线衍射法更加敏感和精确.  相似文献
