Abstract
A manufacturing method for colored fluorine-free imitation ceramic glaze belongs to the field of advanced glass materials. According to the manufacturing method, a melt jacking blowing method is adopted, and the five-layer colored fluorine-free imitation ceramic glaze is prepared by dip blowing according to the sequence of bright material, white material, bright material, pigment and bright material. The manufacturing method overcomes the defect that the traditional imitation ceramic glass production greatly depends on the initial temperature of glass melt phase-splitting or devitrification and the cooling speed during forming; and meanwhile, the manufacturing method realizes very good opacifying effect under the condition of lower phosphorous content, and the common defects of uneven opacifying degree, stripe and the like are not liable to occur.
Description
Technical field
The method of manufacture of the no fluoroform porcelain of a kind of colour coloured glaze belongs to the glass field of new.
Background technology
Imitative porcelain coloured glaze (claiming emulsion opal glass again) is a kind ofly to be widely used in daily utensil, cosmetic package, and the novel material in fields such as architectural lighting and decoration, and industrial scale progressively enlarges in recent years, has good market development prospect.
The reason of imitative porcelain coloured glaze " devitrification " is that the specific refractory power that glass melt has spontaneously been separated out in process of cooling with parent glass differs bigger disperse phase, makes the light that gets into glass by strong scattering but not transmission.The appearance of glass melt disperse phase in process of cooling can be owing to a kind of liquid phase liquid-liquid phase separation that unmixing causes in another kind of liquid phase causes, also maybe be owing to crystallization, micro-bubble or tiny crack cause.Size and concentration different glass goods according to disperse phase can demonstrate opaque or translucent outward appearance.When in glass is formed, introducing tinting material, coloring effect is different from transparent glass material, but obviously thin out.The production of at present imitative porcelain coloured glaze mainly is to make opacifying agent with fluorochemical, in the glass melt process of cooling, separates out a large amount of CaF
2With the NaF crystal, and then cause " devitrification " of glasswork.The temperature of crystallization was lower when the advantage of this fluorochemical emulsion opal glass was the glass melt cooling; The forming operation that helps glasswork; In process of production because the existence of fluorochemical; Can cause problems such as the serious and environmental pollution of glass furnace refractory corrosion, greatly limit its range of application.
The inventor delivers document Effect of network modifiers on the opalescence and crystallization behaviour of opal glasses, Glass Technol.:Eur.J.Glass Sci.Technol.A, 2011; 52 (3): 67 with phosphosilicate glass rheological property research; Wuhan University of Technology's journal, 2010,32:12-16 and the high refined silicate circular that is published in; 2010, the document R of 1:176-183

5Content is more than 6.5wt%, and therefore this temperature that causes coloured glaze melt phase-splitting and crystallization in process of cooling is unfavorable for the forming operation of colored glaze product than higher (generally more than 1250 ℃).In imitative porcelain coloured glaze is produced; Speed of cooling when the most important factor that influences colored glaze product milkiness degree and visual appearance thereof comprises starting temperature and the moulding of phase-splitting of coloured glaze melt or crystallization; The former has determined the forming operation temperature of glasswork, i.e. moulding service temperature will be higher than the starting temperature of phase-splitting or crystallization; The latter has determined the milkiness degree that colored glaze product is final, and speed of cooling is closely related with forming method, and speed of cooling more greatly then phase-splitting or degree of crystallization is low more, and opaque effect is poor more.In addition, in imitative porcelain coloured glaze production, also there is problems such as causing the inhomogeneous or striped of the milkiness degree of glasswork because of batch mixing inequality or refractory corrosion usually.Up to the present, the degree of dependence of speed of cooling is not low when also seeing glass melt phase-splitting or crystallization starting temperature and moulding, and can overcome the no fluoroform porcelain coloured glaze of defectives such as the inhomogeneous and striped of milkiness degree and the report of method of manufacture thereof.
Summary of the invention
The technical problem that the present invention will solve is: overcome the deficiency of prior art, a kind of low-phosphorous milkiness, phase-splitting are provided and recrystallization temperature is low and a kind of environment-protecting color that can eliminate strip flaw does not have the method for manufacture of fluoroform porcelain coloured glaze.

The present invention utilizes the technology of artificial jacking that colored glaze product is processed five-layer structure in the manufacturing of imitative porcelain coloured glaze, and this technology and structure have been slowed down the rate of temperature fall of manufacturing processed in manufacturing processed, realizes slowly cooling; Under lower temperature, realize phase-splitting and crystallization like this, thereby under the condition of low phosphorus pentoxide content, realize extraordinary opaque effect.Solved the drawback that phosphorus pentoxide content is more and mold temperature is high that traditional Vanadium Pentoxide in FLAKES brings as opacifying agent.
The present invention adopts the method for artificial jacking blow molding to make floride-free color pocerlain-like coloured glaze.In white material and the colorant melt cools liquid-liquid phase-splitting having taken place, promptly in host glass, has separated out the spherical rich phosphorus phase that is of a size of about 300nm, thereby caused the intensive scattering of light to make colored glaze product " devitrification "; The phase-splitting starting temperature of white material and colorant melt is all less than 1050 ℃, the service temperature during well below jacking, and the viscosity the during generation of phase-splitting simultaneously is greater than 10
2.5PaS helps blow molding; The manual blowing moulding process is compared with mechanical blow molding, and the speed of cooling of melt is lower, helps improving the phase-splitting degree of glass, and then promotes the milkiness degree; Because the repeatedly jacking operation of this process using, heat up repeatedly and the operation of lowering the temperature helps the elimination of the inhomogeneous and strip flaw of the milkiness degree of glasswork; The difference of bright in addition material and the thermal expansivity of white material glass between 25 ~ 300 ℃ is all less than 6.0 * 10
-7/ ℃, in addition, white material and colorant are in second and the 4th layer in the jacking process, and this has guaranteed that imitative porcelain coloured glaze phenomenon can not occur bursting in manufacturing and daily use thereof.Color is excessive from shallow to deep from inside to outside, makes its color and luster more gorgeous, serious, attractive in appearance, generous, has more ornamental value.
Compared with prior art; The beneficial effect that method of manufacture had of the no fluoroform porcelain of a kind of colour of the present invention coloured glaze is: the high drawback of degree of dependence of speed of cooling that this method of manufacture has overcome traditional imitative porcelain coloured glaze when producing the starting temperature of glass melt phase-splitting or crystallization and moulding, this method of manufacture realizes extraordinary opaque effect and is not prone to defective such as the inhomogeneous and striped of common milkiness degree under the condition of low phosphorus content simultaneously.The product that this method of manufacture is produced is fit to the production of high-end coloured glaze handicraft very much.
