Description
Technical field
The invention belongs to preparing ceramic clinker production technical field, particularly one once burns golden brown frit dry granular and preparation method thereof.
Background technology
Natural stone texture is soft elegant in appearance, elegant style.But large gauge lithotome extremely rare, there is certain radioactivity.The mixture of the devitrified glass microcrystal that to be a kind of glass by certain grain composition formed through coalescent and crystallization and glass.Quality is hard, glittering and translucent.But but devitrified glass is relatively single in design process.And Antique Imitation Tiles can make up this point, the design of thousands of kind can be obtained by micro mist cloth, silk screen, cylinder or ink-jet technology thus meet more human consumer.But it does not possess the space multistory sense of stone material and devitrified glass and glittering and translucent property.And crystallite brick is a kind of novel product integrating stone material, glass and Antique Imitation Tiles advantage.
The surface of biscuit cloth has certain granules to the compound frit powder of joining, the crystallite brick obtained after twice firing is throws brilliant brick, burns throw brilliant brick, secondary burning microcrystal composite board also known as two degree.Throw brilliant brick after polishing, the thickness of clear frit can reach 1 ~ 2mm, and the lines that therefore surface prints has more gradation sense, stereoscopic sensation to the polished tile that the artistic effect of people is more common.But because the low temperature sinter cycle is generally about 160min, the high temperature biscuiting time (cycle 50 ~ 70min) of burning till comparatively for the first time wants slow several times, and production will be made thus to occur inconvenience.First, burn till the more general once burning of cost and want high; In addition, the adobe that biscuiting line is supplied is greater than the demand of glaze firing line, and unnecessary brick needs manually to remove to unload down, after move back to again glaze firing line, this not only adds the labor capacity of employee and occupies warehouse storage space, adds handling cost; The more important thing is, biscuiting line can not empty kiln in the time of free time, biscuiting line thus can be impelled often to change the line of production other products, turn increase the labor capacity of employee, and cause the instability of kiln, and then reduce conforming product rate while changing the line of production.
Once burn if burnt to change into by secondary, so above problem just can fundamentally be resolved.Crystallite brick once burns, and refers to that Wall or floor tile green compact are after glazing, stamp, need have certain granules to the compound frit powder of joining at surperficial cloth last layer, then enters the process that kiln carries out burning till.
Maximum feature due to once-firing is that base glaze reacts ripe together, and this just requires that base substrate is before glaze maturation, gets rid of all volatile components, especially crystal water.General volatile component is just got rid of completely at about 950 DEG C, and this just requires that cullet of glaze has high beginning fusing point, reduces or avoids glaze paint to generate pore.So the special frit of once burning crystallite brick that development is excellent, ensureing the excellence rate of crystallization brick, is the sector technical barrier urgently to be resolved hurrily.
The present invention once burns coloured frit dry granular and itself carries golden brown, therefore the silk screen of ceramics factory's glaze line, cylinder or ink-jet printing process can be removed from, so reduce glaze line length greatly, decrease the employee of related fields, improve production efficiency, improve modular collection degree, for Ceramics Enterprises decreases cost, and improve quality controllable degree.Compared to other technologies, frit dry granular of the present invention can be used in the principle of once-firing legal system for crystallite brick, and compared with other once burn special frit, performance is more superior.Once burn the microcrystal composite board that coloured frit dry granular is produced in conjunction with ceramic body, there is high rigidity, corrosion-resistant, resistance to compression, shock resistance, be stained with dirt, the feature such as radiationless less.Coloured frit dry granular of several different colours, different effect of also can arranging in pairs or groups out, produces colorful crystallite brick.Coloured crystallite brick after polishing has unique artistic effect.

embodiment 7
Green compact apply ground-coat enamel, and consumption is 610 ± 2.5g/m
2, proportion 1.52 ± 0.01; At golden brown frit dry granular prepared by ground-coat enamel surface cloth last layer above-described embodiment 1, consumption is 6000 ± 5g/m
2; The adobe having executed glaze and frit dry granular is fired 130min in the kiln of 1200 DEG C, obtains golden brown crystallite brick.
Sintering character: crystallite brick cover-coat enamel is as bright as a sixpence, in sparkling and crystal-clear soft golden brown, glittering and translucent under the irradiation of light, bright shinny, without the visible pore of naked eyes, pin hole, as shown in Figure 2.
Due to this frit and common brick glaze expansion coefficient similar modelled after an antique, there is certain glaze-body bonding layer, be combined better with adobe and cover-coat enamel.
The golden brown frit dry granular that once burns of the present invention passes through lot of experiments, prove out ground reduces boric acid component and increases alumina component, frit beginning fusing point can be made to be increased to about 1050 DEG C, and before temperature rises to beginning fusing point, the moisture in green compact, organism have volatilized completely.By fluorite and rhombspar, the high temperature viscosity and the comparatively slow ground that reduce frit reduce beginning fusing point, and be beneficial to high temperature bubble and be gathered into air pocket, increase the buoyancy of bubble floating, thus bubble is drained as far as possible completely, throwing is free of pinholes not soil pick-up afterwards.Therefore once burning golden brown frit dry granular beginning fusing point of the present invention is high, temperature flowing is good, is layered on ceramic board and its base substrate can be made to have enough time to be vented at oxidation stage, thus reaches that glaze paint bubble is few, the object of once-firing, energy-saving and emission-reduction, energy consumption comparatively twice firing reduces about 15%;
The golden brown frit dry granular itself that once burns of the present invention carries golden brown, therefore the typography of ceramics factory's glaze line can be removed from, reduce glaze line length, reduce the employee of related fields, improve modular collection degree, improve production efficiency, for Ceramics Enterprises reduces cost, and promote quality controllable degree.
