【摘要】 以废玻璃为主要原料,CaCO₃为发泡剂,烧结制备了泡沫玻璃材料。利用DTA、XRD、电子万能试验机等分析测试手段,研究了CaCO₃含量对泡沫玻璃结构与性能的影响。结果表明:随着CaCO₃添加量的增加,孔径由小变大,形貌从均匀的单峰孔转变成复杂的双峰孔结构,力学性能趋向于开孔结构;750℃下保温15 min可制得体积密度0.23⁰.35 g/cm³、抗压强度0.76⁵.09 MPa、气孔率84.05⁹0.73%的泡沫玻璃材料。更多还原

【Abstract】 Foam glass was prepared through sintering process using waste glass as raw materials,CaCO₃ as foaming agent.The influence of content of CaCO₃ on microstructure and properties of foam glass were evaluated by differential thermal analysis（DTA）,X-ray diffraction（XRD） and electronic universal tester.The results show that with the increasing of CaCO₃ content,the pore diameter increases; The morphology transformed from homogeneous unimodal hole to complicated bimodal hole,the mechanical property was similar to the open pore structure; The foam glass material with an apparent density of 0.23⁰.35 g/cm³,a compressive strength of 0.76⁵.09 MPa,and a porosity of 84.05⁹0.73 prepared at 750 ℃ for 15 min.更多还原
