摘要/Abstract

摘要： 近年来我国陶瓷行业发展迅速,每年产生约1 000万吨陶瓷抛光渣,但只有5%被利用。本文以陶瓷抛光渣作为研究对象,辅以球土、瓷片砂和中温砂等原料,以SiC为孔结构调控剂来制备轻质陶瓷砖,运用一系列正交试验得出最佳的烧结制度,并探究烧成温度与球磨时间对抛光渣轻质陶瓷砖的性能影响。结果表明,烧成温度的升高会改善轻质陶瓷砖内部连通孔和气孔均匀性,在1 160 ℃时,轻质陶瓷砖的体积密度、抗压强度、显气孔率最大,分别为1.24 g/cm³、35 MPa、20%,吸水率为20.38%;当球磨时间从10 min延长至110 min时,轻质陶瓷砖颗粒变细,表面能增大,液相量增多,发泡量增多,使连通孔、气孔均匀性得到改善。

Abstract: In recent years, Chinese ceramic industry has developed rapidly, producing about 10 million tons of ceramic polishing slag every year, but only 5% is used. The ceramic polishing slag was used as the research object, supplemented by raw materials such as clay, porcelain sand and medium temperature sand, and SiC was used as the pore structure regulator to prepare lightweight ceramic bricks. A series of orthogonal experiments were used to obtain the best sintering system, and explore the effects of firing temperature and milling time on performance of polishing slag lightweight ceramic bricks. The results show that an increase in firing temperature can improve the uniformity of internal connected pores and pores in lightweight ceramic bricks. At 1 160 ℃, volume density, compressive strength, and apparent porosity of lightweight ceramic bricks are the highest, and volume density is 1.24 g/cm³, compressive strength is 35 MPa and water absorption rate is 20.38%, respectively. When the ball milling time is extended from 10 to 110 min, the particles become finer, the surface energy increases, the liquid content increases, and the foaming content increases, resulting in improved uniformity of connected pores and pores.

Key words: ceramic polishing slag, lightweight ceramic brick, sintering process, sintering temperature, ball milling time, compressive strength
