摘要
本文以花岗岩废料和玻璃废渣为原料、SiC为发泡剂,采用粉末烧结法制备了高孔隙率、低吸水率的全固废发泡陶瓷,探究了花岗岩废料和玻璃废渣配合比、烧结温度、发泡剂掺量对发泡陶瓷孔结构及性能的影响.结果表明:花岗岩废料形成了发泡陶瓷的骨架结构,玻璃废渣具有助熔作用;当玻璃废渣掺量为20％(质量分数)时,烧结温度降低了 40℃.在1 110～1 150 ℃下制备的发泡陶瓷抗压强度为2.23～0.41 MPa,体积密度为468.41～326.31 kg/m3,孔隙率为79.15％～86.81％,吸水率为0.96％～1.00％,平均孔径为0.49～1.43 mm,实现了对发泡陶瓷孔径的有效调控,满足了不同应用场景对发泡陶瓷不同孔径的需求.本研究为花岗岩废料和玻璃废渣的规模化利用及不同孔径发泡陶瓷的制备提供了技术支持.
Abstract
In this paper,all-solid waste foamed ceramics with high porosity and low water absorption were prepared by powder sintering method,using granite waste and glass waste residue as raw materials and SiC as foaming agent.The effects of mix ratio of granite waste and glass waste residue,sintering temperature,and foaming agent content on pore structure and properties of foamed ceramics were explored.The results show that granite waste forms a framework structure of foamed ceramics,while glass waste residue has a melting aid effect.When glass waste residue content is 20％(mass fraction),the sintering temperature decreases by 40℃.The compressive strength of foamed ceramics prepared at 1 110～1 150 ℃ is 2.23～0.41 MPa,the bulk density is 468.41～326.31 kg/m3,the porosity is 79.15％～86.81％,the water absorption rate is 0.96％～1.00％and the average pore size is 0.49～1.43 mm,which effectively regulates the pore size of foamed ceramics and meets the needs of different application scenarios for different pore sizes of foamed ceramics.This study provides technical support for the large-scale utilization of granite waste and glass waste residue,as well as the preparation of foamed ceramics with different pore sizes.
