摘要
通过在沸石分子筛中添加膨胀石墨和发泡剂并固结成型进行处理 ,使吸附剂的导热系数和渗透性有了显著提高 ,并测定了几种吸附剂的导热系数 ,采用SEM观察了发泡前后的沸石分子筛的晶体结构和微观形貌的变化 ,分析了膨胀石墨所具有的特性是使其成为合适的添加剂的原因。
The low thermal conductivity of the solid adsorbent is one of the major drawbacks of the adsorption heat pumps development.By added expsnded graphite and blowing agent and consolidated,the thermal conductivity of composite adsorbent show a great improvement.The performance of reformative zeolite is improved.
