Description
Technical field
The invention belongs to field of ceramic processing, relate to a kind of ceramics vitrified brick, its blank and preparation method thereof.
Background technology
Architectural pottery is AND ENERGY RESOURCES CONSUMPTION IN CHINA rich and influential family, consumes a large amount of raw materials and fuel, and has discharged a large amount of CO
2waste gas, exacerbates global greenhouse effect, and be the heavy calamity industry of domestic and international CO2 exhaust gas emission, vitrified tile is one of architectural pottery main products.At present, how the conventional firing temperature of vitrified tile, between 1210 ± 20 DEG C, reduces firing temperature, reduces firing period, reduce costs the focus becoming those skilled in the art's research.The people such as the Deng Jianguo of Zi Gong million peak company, local raw material is utilized to manufacture experimently the production technique of colored macrobead polished tile, its firing temperature is 1185-1200 DEG C, firing period (utilizes local raw material to manufacture experimently colored macrobead polished tile at about 60min, Deng Jianguo, Chinese pottery industry, 2002,6:46-48).The people such as Yu Xiaoqin utilized local inferior raw material to carry out reduce vitrified tile firing temperature test; firing temperature is 1170-1180 DEG C, firing period 30min (development of low temperature fast firing porcelain floor tile, Yu Xiaoqin etc.; 2001,37 (1): 33-34).CN1562870 discloses the temperature of glaze firing (1200-1220 DEG C) of a kind of utilization a little less than Shi porcelain, burns out the household china higher than hard-paste intensity.DE20001031430 discloses a kind of low frit apatite glass-ceramics, and sintering temperature is 1200-1650 DEG C.
Jingdezhen Ceramic Liu Kun etc.; provide a kind of research and development of very low temperature vitrified tile; further investigation architectural pottery body crack defects affected by multiple elements design flux system and optimization; while obviously reducing product sintering temperature (100 DEG C); less than 1100 DEG C sintering are successfully prepared; and performance meets and higher than the product (research and development of very low temperature (≤1100 DEG C) vitrified tile of national vitrified tile standard; Liu Kun etc.; Chinese pottery industry 2012,19 (6): 14-17).Although the document is reported, greatly reduce firing temperature, near less than 1100 DEG C, the full section of the document its firing period unexposed extends than prior art and remains unchanged.
Mostly the main method that existing architectural pottery reduces firing temperature is to adopt and adds method that is single or the less low temperature flux of kind in a large number, and base substrate is sintered at a lower temperature.But this method also exists following technological deficiency: base substrate is generating close to there is no liquid phase during eutectic point, but once arrive lowest total of the melting point temperature just occur suddenly a large amount of liquid phase, and amount of liquid phase raises with temperature and increases sharply, thus causes porcelain base to be sharply out of shape.Therefore, prior art and method are while reduction sintering temperature, also obviously cause that product firing range narrows, product is easily out of shape and fragility is large, therefore cannot ensure the property indices of product in large-scale production process, not have the report of large production technology so far.
Visible, mostly only rely on a large amount of cullet and industrial reagent of using to reduce firing temperature in prior art, cause the physicochemical property of product to decline, the appearance of the problems such as water-intake rate is high, conforming product rate is low.
