Description
Technical field
The invention belongs to glazed tiles and manufacture field, particularly to the preparation method of a kind of acidproof coal ash of resistance to agar glazed tiles.
Background technology
Glazed tiles, brilliant, it is Chinese traditional architecture object, generally imposes the colored lead glazes such as golden yellow, emerald green, dark blue, because of
The favourite son that material is firm, bright in luster, glaze colours is smooth, always immortal in building ceramics.China is as far back as north and south
Towards period just at architectural use glazed tile member as ornament, to imperial palace building large-scale use glazed tiles, the Ming Dynasty ten during the Yuan Dynasty
Three mounds and the Nine-Dragon Wall are all the masterpiece on glazed tiles architectural history.
Along with development and people's living condition of science and technology are become better and better, the glazed tiles that noble uses originally progress into common people's
Ordinary life, meanwhile, the development of tourist industry is also greatly facilitated people's demand for glazed tiles.
But due to China is vast in territory, climate change is relatively big, and the freexing tolerance for glazed tiles can propose the highest requirement；With
Time, along with the aggravation of atmosphere pollution, the infringement of construction material is increased the weight of by acid rain day by day, and the ecological balance wrecks, and there was an abrupt change in weather
The most gradually aggravating, the requirement for the acid corrosion-resistant of antique glazed tile is higher.
Flyash, is to receive the flue gas after coal combustion to catch the fine ash got off, and flyash is that the primary solids that coal-burning power plant discharges gives up
Thing.The main oxides of power plants flyash consists of: SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2 etc..
Flyash is one of industrial residue that the current discharge capacity of China is bigger, along with the development of power industry, the flyash discharge of coal-burning power plant
Amount increases year by year.Substantial amounts of flyash is untreated, will produce airborne dust, atmosphere pollution；River can be caused to become silted up if entering water system
Plug, and human body and biology also can be worked the mischief by toxic chemical substance therein, how to be got up by utilization of fly ash is also to grind now
The focus studied carefully.
Summary of the invention
It is an object of the invention to, for the problems referred to above, develop the preparation method of a kind of acidproof coal ash of resistance to agar glazed tiles, its technique
