Abstract
Foam glass is a special glass inorganic non —metallic material full of connectivity or closed internal pores.It is mainly produced by broken glass or waste glass.And blowing agents,co—solvents,enhancers as additive.Batch formed by the way of crushing and grinding.It can be produced after a warm —cold,hot melt,foam,foam stabilization,annealing and other processes.In this thesis,(green)waste container glass is the main raw material,pure carbon and CaCO3as blo-wing agent.And Na2CO3,(NaPO3)6as additive.Low —density foam glass prepared by powder casting.Finally,the re-sults showed that:Pure carbon and CaCO3as the blowing agent,calcium carbonate content of 3.0%,pure carbon content of 0.4%,and the foaming temperature 840 ℃,holding time 70 min,foam glass prepared density of about 240 kg/m3,and the pore size Inside the sample uniform.关键词
