【摘要】：以煤矸石空心微珠和玻璃空心微珠坯体为主要原料,采用滚动成球法制备陶粒生坯,经烘干、烧结,得到轻质陶粒,研究了烧结温度、保温时间以及玻璃粉添加量对空心微珠轻质陶粒性能的影响。结果表明:随着烧结温度的升高,陶粒的表观密度和吸水率逐渐增大,颗粒抗压强度先增大后逐渐减小;烧结温度为700℃,单颗粒抗压强度为200.5 N,达到最大值。随着保温时间的延长,颗粒抗压强度先增大后减小。加入玻璃粉可以明显提高陶粒的单颗粒抗压强度,并且随着玻璃粉加入量的增大,颗粒抗压强度显著增大,700℃烧结的样品中玻璃粉加入量为25%(质量分数)时,单颗粒抗压强度增大到327.5 N,提高了63.3%。
[Abstract]:Using coal gangue hollow bead and glass hollow bead as the main raw materials, the raw material of ceramic green was prepared by rolling ball forming method. After drying, sintered, light ceramsite was obtained. The sintering temperature was studied. The effect of holding time and glass powder addition on the properties of hollow microbeads. The results show that with the increase of sintering temperature, the apparent density and water absorption of ceramsite increase gradually, and the compressive strength of the particle increases first and then decreases, and the compressive strength of single particle reaches the maximum value at 700 鈩，
