| 摘 要： | 以斑岩型铜矿尾矿、高岭土、玻璃粉为主要原料，制备连通孔陶瓷透水材料。研究了骨料配比、结合料用量、成型压力和烧成制度对连通孔陶瓷透水材料抗折强度和透水系数的影响。当m(铜尾矿):m(高岭土):m(玻璃粉)为7:3:2、成型压力为1 MPa、烧成温度为1 150 ℃、保温时间为90 min时，工艺流程最佳。此时，连通孔陶瓷透水材料抗折强度为3.9 MPa，透水系数为2.7×10-2 cm/s，劈裂抗拉强度为3.7 MPa，耐磨性磨坑长度为25.2 mm，抗冻性为D50。

| Abstract: | The connected porous and water-permeable ceramic materials were prepared with porphyry copper tailings, kaolin and glass powder as main raw materials. The flexural strength and water permeability coefficient of the connected porous and water-permeable ceramic materials were studied at different aggregate ratio, binder dosage, molding pressure and firing system. The results showed that when the ratio of copper tailings, kaolin and glass powder was 7 : 3 : 2, molding pressure was 1 MPa, sintering temperature was 1 150 ℃, and holding time was 90 min, the flexural strength, water permeability coefficient, splitting tensile strength, the wear-resistant pit length, and frost resistance of the prepared connected porous and water-permeable ceramic materials were 3.9 MPa, 2.7×10-2 cm/s, 3.7 MPa, 25.2 mm, and D50, respectively. |
