Technical field
The present invention relates to glass ceramic material technical field, it is specifically related to a kind of pottery foam glass particle and its preparation method.
Background technology
Along with the fast development of economy, the demand of electric power is risen by all trades and professions day by day. Distinguishing according to the source of electric power, the source of generating mainly contains the modes such as waterpower, firepower, wind-force, underground heat, photo-thermal. Flyash is the primary solids refuse that coal-burning power plant discharges. The main oxides of power plants flyash consists of: SiO2��Al2O3��FeO��Fe2O3��CaO��TiO2Deng; Flyash is one of industrial residue that the current discharge capacity of China is bigger, and along with the development of power industry, the flyash quantity discharged of coal-burning power plant increases year by year. A large amount of flyash does not add process, will produce airborne dust, atmosphere pollution; River can be caused to silt up if entering water system, and human body and biology also can be caused harm by toxic chemical substance wherein.
Glass is not only widely used among the daily life of building construction and the people, and develops into research and production and the indispensable novel material of sophisticated technology. Inevitably produce many glass wastes simultaneously, form a large amount of cullet. By glasswork, under normal production scenarios, the corner glass scaled off from former of sheet glass accounts for the 15%-25% of glass production total amount, also has quite a few cullet to be the cullet regularly stopping production and producing, accounts for the 5%-10% of glass production total amount. Producing the loss in transport and use procedure of melting furnaces processing temperature of having a surplus under abnormal condition fluctuates once in a while or raw materials quality and batch uniformity changes suddenly and misoperation etc. causes production instability generate cullet and glasswork, its quantity then is difficult to estimate. Glass waste silk is a kind of glass waste residue certainly led in fiber glass industry production process, and generation generally accounts for about the 15% of glass output. The glass packaging bottle tank abandoned in people's daily life and the glass port fragment smashed etc. are also one of sources producing cullet. Cullet class material, its chemical property is stablized, and does not rot, does not burn, can not degrade, and a large amount of cullet brought inconvenience both to the production of people and life, again environment was created load. Therefore, how to carry out cullet resource and it is melted into a current problem demanding prompt solution.
