Described beautiful matter glass-ceramic clad plate preparation method:
In the beautiful matter glass ceramics frit of said preparation 1. dry granular, said quartz, potassium felspar sand, albite, calcite, rhombspar, barium carbonate, yellow soda ash, salt of wormwood, borax, boric acid, calcium phosphate consumption is separately all confirmed in the said composition range that sets beautiful matter glass ceramics frit dry granular in advance;
In said preparation ceramic green 2., said kaolin, clay, quartz, potassium felspar sand, albite, talcum, water reducer consumption is separately all confirmed in setting the said composition range of ceramic green in advance;
In said preparation ground-coat enamel 3., said calcined kaolin, quartz, potassium felspar sand, albite, calcite, talcum, rhombspar, zinc oxide, zirconium English powder, nepheline, thickening material, water reducer consumption are separately all confirmed in setting the said composition range of ground-coat enamel in advance.
Described beautiful matter glass-ceramic clad plate preparation method:
In said preparation ceramic green 2., said kaolin is selected to be replaced by black mud, makes loss on ignition＜4.7% of said ceramic green;
In said preparation ground-coat enamel 3., the flow velocity of said pulpous state ground-coat enamel is grace formula viscosity 16-18 second.
Principle of the present invention is:
The key of beautiful matter glass ceramics frit is to let frit divide the phase transformation milkiness, and produces crystallite, and the refractive index of this crystallite should be too not high.If refractive index is too high, according to light scattering theory, can produce strong scattering, cause opacity high, beautiful texture is reduced, even become opaque.For this reason, we to select calcium phosphate be the opacifying agent of phase-splitting.One of its reason is that phosphorus is four coordinations in silicate glass; Phosphorus itself is again+5 valency valence states; Therefore form asymmetric phosphorus oxygen tetrahedron; Be in four keys of phosphorus and oxygen; One of them key is two keys; I.e.
this asymmetric tetrahedron, the symmetric silicon-oxy tetrahedron that in the glass structure of silicate, distributes
lining is easy to phase-splitting; Two of its reason is in the higher silicate glasses of calcium contents, and phosphorus is very easy to generate the calcium phosphate crystallite with calcium, and calcium phosphate crystallite refractive index is 1.59-1.62, an average refractive index (1.55) a little more than silicate glass.Satisfied the milkiness condition that produces beautiful texture.In addition, the frit melting temperature that also should begin is higher, and the sintering posterior spiracle is few and do not react with the onglazed pattern color.Through test of many times, summary, we have found out the chemical ingredients scope 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
