Description
Technical field
The invention belongs to glazed tiles additive preparation field, particularly to the preparation side of a kind of low grade fever's glazed tiles additive
Method.
Background technology
Glazed tiles are one ancient, traditional ceramic materials of China.Along with the development of tourist industry, people are for glazed tiles
Demand is also more and more, is also more and more higher to its requirement.
Existing glazed tiles are the most all to use multiple pug mixed sintering to form, and its glaze layer is the thickest and produces and answers
Power, quality weight, it is easily caused product glaze and be full of cracks occurs, collapses the defect of stripping.The most smooth, and pug is the easiest
Producing and pollute, cost and energy consumption are high, and the quality of product is not sufficiently stable, and its glaze glossiness is inadequate, and colour generation is abundant not, stable,
Easily fade under climate variability area or long sunlight are irradiated.At present, glaze sintering temperature is often higher than 1000 DEG C.As
Zou little Ling;Deng in " Chinese pottery " the 06th phase in 2016 with Pb-Zn-Ag ore mine tailing as primary raw material, be aided with red soil, Kaolin,
1160-1170 DEG C of calcining forms compact structure glazed tiles.Result shows: use formula consist of Pb-Zn-Ag ore mine tailing 36-37%,
Red soil 45-46% Kaolin 18-19%, prepared glazed tiles base substrate, XRD analysis principal crystalline phase has quartz, anorthite, mullite
Deng, scanning electron microscope (SEM) result shows glazed tiles base substrate granule close-packed arrays, has a small amount of space between granule.Glaze is more flat
Whole, glaze-ceramic interface is tight.The indexs such as the water absorption rate of sample, bending failure loading, thermal stability and frost resistance all can reach
" colored glaze goods " JC/T765-2006 standard-required.This not only make use of Pb-Zn tailings, alleviates its pollution to environment, again
Reduce glazed tiles production cost, turn waste into wealth.But its sintering temperature is 1160-1170 DEG C, belongs to highly energy-consuming, pollute again ring
Border, is not suitable for future economy strategy development, therefore, considers from energy-conservation and national angle, and following development is inevitable burns toward low temperature
Knot, energy-conserving and environment-protective development.The reduction of sintering temperature, can reduce energy consumption, reduces the cost of glaze goods, meets the need of social development
Want.The research of ultralow sintering process so that it is purposes is more extensive, can be used in the reparation of glazed tiles product defect, reduces coloured glaze
The substandard products of watt goods, reduce the waste of resource.
