The effects of the amount of nylon-66 short-fiber and its bonding to a chloroprene rubber were studied. The following results were obtained: (a) The tensile strength of short-fiber reinforced rubber (SFRR) exhibits a dilution effect in each interphase. It was found that the interphase conditions have an important effect on the dilution ratio and the critical fiber content. The specimen with double coatings of the bonding agent and a rubber solution, becomes the best of 5 interphase models. Both the yield strength and tensile moduli significantly improve with fiber content. (b) The spring constant (SC) of unreinforced rubber decreases after the fatigue test, however, the SC of all reinforced rubbers increases. The change in SC of reinforced rubber decreases with fiber content. The better the interphase condition, the smaller the change of the SC. (c) The temperature of rubber increases about 2.6 fold after the fatigue test. The reinforced rubbers show a 1.4 to 2.2 fold increase in temperature. The temperature changes during the fatigue test of the reinforced rubbers decrease with increasing fiber content, as well as with improved interphase bonding. 相似文献

采用分子动力学方法研究纳米尺度下液氩在过热基板上的沸腾过程。通过调节固液间相互作用的方式改变壁面润湿性,模拟并分析了壁面润湿性对沸腾过程中能量传递和液体运动情况的影响。结果表明:不同润湿性表面均会发生固液分离的现象,但是固体表面附近吸附的氩原子数密度随润湿性增强而增大;润湿性较强时,液体的能量上升快,热通量高,液体内部温度梯度大,发生固液分离时间早,系统中氩的温度和能量低,上升过程中液氩密度、厚度变化小;润湿性较弱时,液体的能量上升慢,热通量小,液体内部温度梯度小,发生固液分离时间延后,系统中氩的温度、能量更高,上升过程中液氩密度、厚度变化较大。下部气体压力整体上大于上部气体压力,发生固液分离时润湿性越强的表面上液体上下压差越大,首次上升过程能达到的高度越高,所需时间越短。 相似文献

合成了可紫外光固化的低黏度环氧丙烯酸酯树脂,通过红外光谱、核磁共振氢谱、碳谱对树脂结构进行了表征;采用综合热分析仪(DSC-TG)对树脂固化膜的耐热性能进行了分析。结果表明,在树脂中添加活性单体时,随单体官能度的增加,固化膜的耐热性能增加,但双官能团单体的用量对固化膜的耐热性能没有明显影响。固化膜具有较好的耐热性,初始分解温度为330.7℃,玻璃化转变温度为76.9℃。所得树脂黏度仅为3~4Pa.s(60℃),为市售产品的1/3,附着力1级,硬度4 H,耐水性能优异,无需添加单体使用。 相似文献

采用硝酸改性-高温活化法对废弃的兰炭末进行处理,对改性前后的兰炭末进行了SEM和BET表征,测定了改性后的兰炭末对对硝基苯酚的吸附性能,通过静态吸附实验研究了改性兰炭末对对硝基苯酚的吸附平衡和动力学特征。结果表明,兰炭末经改性后表面粗糙度明显增加,孔道明显增多,总孔容和比表面积分别增加了7.1倍和4.3倍; Langmuir方程可较好地描述对硝基苯酚在改性兰炭末上的吸附平衡,特征分离系数RL为0~1,为优惠吸附,温度升高有利于吸附的进行;动力学研究表明,对硝基苯酚在改性兰炭末上的吸附过程符合HO准二级动力学模型,颗粒外的液膜扩散是决定吸附速率的控制步骤,吸附过程的表观活化能Ea为9.825kJ/mol。改性兰炭末对对硝基苯酚有较好的吸附能力,328K下平衡吸附量达158.5mg/g,可作为一种廉价、高效的酚类废水处理用吸附剂,有很好的工业化应用前景。 相似文献

pH-responsive hydrogels composed of methacrylic acid (MAA) grafted on poly(ethylene oxide)-poly(vinylpyrrolidone)(PEO-PVP) network were made by electron beam irradiation technique. The grafting was carried out at various concentrations of MAA with different irradiation doses. The gels were characterized by IR, DSC and SEM techniques. The swelling behavior of the gels was studied under different pH conditions. The swelling parameters were evaluated. The mode of water diffusion into the gels was found to be structure-dependent. The pH responsiveness of the gels was evident from the enhanced swelling of the gels with increasing pH of the medium. The suitability of these gels as matrix materials for stimuli-responsive sustained-release drug formulations was studied. The in vitro release profile of an antihypertensive drug, metoprolol tartarate, from these gels was studied at pH 1.2 and 7.4. The extent of drug release is found to be pH-dependent. The data were analyzed to understand the mechanism of drug release from the gels. The gels exhibited diffusion-controlled release behavior. Drug release kinetic analysis indicated “first order” release where the amount of drug released is dependent on the matrix drug load and the value of the diffusion coefficient indicated anomalous diffusion. 相似文献
