Principle of the present invention is:
The key of beautiful matter glass ceramics frit allows frit divide phase transformation milkiness, and produce crystallite, and the refractive index of this crystallite should be too not high.If refractive index is too high, according to light scattering theory, strong scattering can be produced, cause opacity high, beautiful texture be reduced, even becomes opaque.For this reason, we select calcium phosphate to be the opacifying agent of phase-splitting.One of its reason is phosphorus is four coordinations in silicate glass, and phosphorus itself, again in+5 valency valence states, therefore forms asymmetric phosphorus oxygen tetrahedron, i.e., in four keys of phosphorus and oxygen, one of them key is double bond, namely
this asymmetric tetrahedron, the silicon-oxy tetrahedron of the symmetry distributed in the glass structure of silicate (
) inner, be easy to phase-splitting; Two of its reason is in the silicate glasses that calcium contents is higher, and phosphorus very easily generates calcium phosphate crystallite with calcium, and calcium phosphate crystallite refractive index is 1.59-1.62, a little more than the average refractive index (1.55) of silicate glass.Meet the milkiness condition producing beautiful texture.In addition, the frit melting temperature that also should begin is higher, and sintering posterior spiracle is few and do not react with over-glaze decoration pattern color.Through test of many times, summary, we have found out the chemical composition ranges of the glass ceramics frit with These characteristics: SiO
250-70%, Al
2o
35-20%, CaO 0-10%, MgO 0-8%, K
2o+Na
2o 2-10%, BaO 0-8%, B

50-5%.Mentioned component will be met, fineness is less than 100 object quartz, potassium felspar sand, albite, calcite, rhombspar, barium carbonate, sodium carbonate, salt of wormwood, borax, boric acid, calcium phosphate mix, send in cell furnace and melt, glass melting temperature 1520-1600 DEG C.The melt melted obtains 30-200 object frit dry granular after shrend, oven dry, fragmentation, screening.Then, by dry type material distributing machine, the ceramic body of printed floral designs is uniformly distributed with the beautiful matter glass ceramics frit dry granular prepared, and cloth doses is 3.5-6Kg/m
2, then spray stationary liquid and fix, reenter roller kiln and burn till.The top temperature of burning till is 1100-1200 DEG C, and firing period is 60-180 minute.Work in-process after burning till through scraping thicknessing, rough polishing, essence throwings, edging, chamfering, air-dry, color separation, classification operation, obtain the beautiful matter glass-ceramic clad plate product of beautiful matter glass ceramics frit dry granular and over-glaze decoration ceramic body compound again.
Owing to have employed technical scheme provided by the invention; Owing to present invention employs " the beautiful matter glass ceramics frit dry granular selecting material in predetermined prod composition range " gordian technique; Described in principle of work of the present invention; Due to the present invention implement on ceramic green ground-coat enamel make ground-coat enamel base after printing glaze make again over-glaze decoration greenwave, spray methylcellulose gum after charity beautiful matter glass ceramics frit dry granular makes over-glaze decoration frit dry granular greenwave on over-glaze decoration greenwave and be fixed and make and carry out being fired into work in-process until burning greenwave be prepared into beautiful matter glass-ceramic clad plate finished product after scraping thicknessing, rough polishing, essence throwing, edging, chamfering, air-dry, pick, color separation, classification.Make the present invention compared with existing known technology and present situation, the beneficial effect of acquisition is:
