酸度系数对矿渣棉理化性能的影响
|
摘要
为了确定矿渣棉生产过程中调质高炉渣最佳酸度系数,实验室条件下通过四辊离心法制备不同酸度系数的矿渣棉,通过矿渣棉理化性能检测,研究了酸度系数对矿渣棉理化性能的影响规律。研究结果表明,随着酸度系数的增大,矿渣棉直径呈指数增长;矿渣棉主要呈玻璃体结构,随着酸度系数的增大,其析晶温度降低,成纤过程温度变宽;不同酸度系数矿渣棉在弱酸性条件下其微观形貌表面无明显变化,表面仍较光滑;在碱性条件下,其表面均出现腐蚀现象,较为粗糙,有明显的新生水化相出现。矿渣棉实际生产过程中,高炉渣酸度系数应控制在1.0~1.4较为适宜。
In order to determine the optimum acidity coefficient of modifying blast furnace slag in slag wool production process. Using four-roll centrifugation method,slag wool with different acidity coefficients was prepared under the laboratory condition,and the influences of acidity coefficient on the physical and chemical properties of slag cotton was studied by testing the physical and chemical performances of mineral wool. The results show that the diameter of slag wool increased exponentially with the increase of acidity coefficient,the mineral wool mainly consisted with vitreous body structure. With the increase of acidity coefficient,the crystallization temperature decreased,and the temperature needed to form fiber became wide. Under the condition of weak acid,the microstructure on the surface of slag wool with different acidity coefficients had no obvious change,and the surface was still relatively smooth. Under the alkaline conditions,corrosion phenomenon appeared on the surface which was more rough,accompanying by the generation of newborn hydration phase. It is better to maintain the blast furnace slag acidity coefficient between 1.0-1.4 during the production of slag wool.
