花岗岩废料与玻璃废渣制备发泡陶瓷的研究
Preparation of Foamed Ceramics from Granite Waste and Glass Waste Residue
摘要
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.关键词
