Description
Technical field
The present invention relates to a kind of preparation method of aventurine fluoride-free opal glass.
Background technology
Emulsion opal glass mainly contains Fluoride Opal Glass, Phosphate Opaque Glass, oxide compound emulsion opal glass, phase-splitting emulsion opal glass.Emulsion opal glass is widely used in the aspects such as instrument, architectural lighting, medicine equipment, industrial art decoration, daily utensil, ceramic whiteware bottle modelled after an antique, art owing to its special optical property and decorate properties, with penetrating bright glassy phase ratio, emulsion opal glass has the characteristics such as color and luster is soft, noble and unsullied grace.In recent years, the application of emulsion opal glass is increasingly extensive, and industrial scale also progressively enlarging, demonstrates good future develop.
The glass opaque mechanism mainly contains four kinds of crystal grain milkiness, phase-splitting milkiness, no cofusing particle milkiness and micro-bubble milkiness, producer nearly all adopts the first milkiness method both at home and abroad at present, wherein fluorite and Sodium Silicofluoride are modal opacifying agent, separate out a large amount of CaF when glass metal cools off
2With NaF crystal grain, because the specific refractory power difference of these two kinds of crystal grain and host glass is larger, make light produce scattering, cause opaque effect.Opacifying agent commonly used is fluorochemical, closes sodium aluminate, aluminum fluoride, Potassium monofluoride etc. such as fluorite, Sodium Silicofluoride, hexafluoro.Process, found in the processes such as shaping, processing at raw material, the dust volatile matter of fluorochemical causes environmental pollution, and simultaneously, fluorochemical also can cause acute human and chronic poisoning, and therefore the use for fluorochemical is restricted.Although Fluoride Opal Glass has the advantages such as grain growing speed is fast, in its production process, exist grain growing to be not easy the problems such as control, fluorochemical volatilization contaminate environment.
At present, Sodium Silicofluoride is expensive on the market, and there is lack of raw materials to cause manufacturing Fluoride Opal Glass goods, and cost rises.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of aventurine fluoride-free opal glass, the aventurine fluoride-free opal glass of the method preparation not only has the characteristics of emulsion opal glass, and has the strip crystal, and is glittering.
To achieve these goals, the technical solution used in the present invention is: a kind of preparation method of aventurine fluoride-free opal glass is characterized in that it comprises the steps:
1) choosing of raw material: each oxide compound forms (essentially consist) and shared mass fraction is: 65～75 parts silicon-dioxide, 0.5～2.0 part aluminum oxide, 8.0～12.0 parts calcium oxide, 2.0～5.0 parts magnesium oxide, 9～15 parts sodium oxide, 1～5 part Vanadium Pentoxide in FLAKES, 0.5～1 part boron oxide, 0.5～1.5 part zinc oxide, 0.5～1 part zirconium white, 0.5～1 part bismuth oxide and 0.2～0.5 part cerium oxide
Carry out charge calculation with above-mentioned oxide component content, obtain charger sheet, introduce various oxide compounds with raw mineral materials and industrial chemicals respectively, and carry out weighing, mixing, obtain glass batch;
2), with step 1) in glass batch put in the horse shoe flame glass melter and melt, the temperature of fusion scope is 1500～1530 ℃, and temperature rise rate is 10-20 ℃/minute, and soaking time is 2-8 hour, under this temperature, glass metal carries out clarification and homogenization; Melt qualified glass metal by in the melting furnaces the glass metal separation device---behind the dog-hole, enter into cooling end, the temperature of cooling end is controlled at 1300～1350 ℃, provide rational processing condition for mixing the aventurine(glass) material;
3), pass through the charging opening of the cooling end rear end of horse shoe flame glass melter, be that the aventurine(glass) material of 1～15mm joins in the cooling end, by step 1 equably with the granularity scope) in the ratio of oxide component total mass umber and the mass fraction of aventurine(glass) material be 100 parts: 1～30 part adds the aventurine(glass) material; Under the acting in conjunction of temperature, density, chemical composition, glass metal stream, two kinds of mutual meltings of glass, diffusion; Oarse-grained aventurine(glass) material will melt, be dispersed into short grained plate crystal; Obtain being with aventurine glass metal;
4), step 3) gained be with aventurine glass metal, the supply channel that links to each other by the cooling end with the horse shoe flame glass melter flows to the forming machine of its underpart, obtains aventurine fluoride-free opal glass; Glass metal further cools off in supply channel, and its cooling temperature scope is 1300～1050 ℃; At this temperature section, glass metal is at P
2O
5, ZrO
2, B
2O
3Etc. carrying out phase-splitting under the effect of component, make segment glass liquid in this temperature section phase-splitting.
Described aventurine(glass) material is the copper aventurine glass material.
Be with aventurine glass metal to be shaped to tableware, light fixture, artwork or artwork through forming machine.
Aventurine(glass) material in the aventurine fluoride-free opal glass of the present invention is by adding the mode of aventurine(glass) material, before the emulsion opal glass formed product, adds in the process of cooling of the liquid of glass.The aventurine(glass) material add the implantation site in the rear end of melting furnaces cooling end, this moment, the temperature of glass metal was higher, after the aventurine(glass) material evenly adds, carried out fully melting with wandering, so that the more firm structure of both formation with parent glass.
In the present invention, in the aventurine fluoride-free opal glass in the total mass of an oxide compound as 100 parts, before its moulding, entrain into the aventurine(glass) material, the total mass of aventurine(glass) material can be any one numerical value in 1～30 part.Because the aventurine(glass) material is to add at cooling end, therefore, its granularity scope can be slightly larger, is generally 1～15mm.Prepared like this aventurine fluoride-free opal glass can according to the variation of aventurine(glass) material content, form series product.
The invention has the beneficial effects as follows: the aventurine fluoride-free opal glass of the method preparation not only has the characteristics of emulsion opal glass, and has the strip crystal, and is glittering.Be specially adapted to the production of the products such as emulsion opal glass tableware, light fixture, artwork, artwork.The characteristics such as color and luster is soft so that this product has, noble and unsullied grace.
