本文主要研究内容
作者张鑫林(2019)在《海泡石基储能材料的制备及热湿性能研究》一文中研究指出:随着人们对建筑热湿环境愈来愈重视,开发调温、调湿材料逐步成为复合型建筑功能材料研究和应用领域的热点。本文以海泡石为负载载体制备了一种兼具调温调湿双功能材料。首先制备了月桂酸-十四酸和十六酸-十四醇两组共晶系。采用CTAB对海泡石原矿进行有机改性,通过液相插层法制备了不同LA-MA共晶系占比的海泡石基复合相变材料。采用步冷曲线法和“干燥器-气候箱”法对月桂酸-十四酸/海泡石复合相变材料的热湿性能进行测试,并用归一化法对其热湿性能进行综合性评价。将LA-MA/海泡石复合储能材料加入到石膏粉中制成储能石膏试板测试石膏试板的蓄热能力和调湿能力。通过实验研究得到以下结论:(1)月桂酸-十四酸共晶系无过冷现象,而十六酸-十四醇共晶系则出现微弱的过冷现象。月桂酸-十四酸共晶系的最低共熔点质量比为63:37(月桂酸:十四酸),熔点为32.71℃,相变潜热为158.2J/g。十六酸-十四醇共晶系的最低共熔点质量比为18:82(十六酸:十四醇),相变温度为32.35℃,相变潜热为122.6J/g。红外谱测试显示两组共晶系材料均未发生化学反应产生新物质。同时,400次加速热循环后它们的热物性未发生明显变化。(2)月桂酸-十四酸/海泡石复合储能材料的控温性能和调湿性能存在“矛盾对立”的关系,即随着月桂酸-十四酸共晶系掺量的增加,月桂酸-十四酸/海泡石复合储能材料的控温性能的优势越明显,其吸湿能力也会随之减弱。通过归一法对热湿性能进行综合性评价,发现当月桂酸-十四酸共晶系掺入量为30%,具有最佳的的热湿综合性能,并且其相变温度为32.63℃,相变潜热为61.89J/g。热循环稳定实验和热重实验表明,海泡石复合相变材料热稳定良好并且不会发生明显渗漏现象,在200℃以下不易挥发分解成气体。(3)储能石膏试板隔热性能受其表面传入热量有影响。随着月桂酸-十四酸/海泡石复合储能材料掺量增加可以提高相变试块的蓄、放热性能,同时表面温度响应速率也会发生变化。此外,复合储能材料掺入到石膏中,其调湿性能均比纯石膏和海泡石基储能更优越,这主要是海泡石和石膏粉之间产生更多的空隙,可用作吸附空气中的水分子。同时,在相同相对湿度环境下,储能石膏试块的放湿性能略小于吸湿量,验证了海泡石基复合储能材料在多次吸放湿循环后,其吸湿容量下降随后又趋于稳定的原因。
