Abstract
An opal glass plate prepared by continuous calendering method contains SiO2 (55-75 Wt%), Al2O3 (2-10), B2O3 (0.3-3), CaO (2-8), MgO (0.1-0.5), ZnO (2-6), K2O (1-5), No2O (5.5-15.7), F (3-9.25), As2O5 (0.1-0.7) and Sb2O5 (0.01-0.3).
Description
Technical field:
The present invention relates to the production method of dull and stereotyped emulsion opal glass.
Background technology:
Compare with existing conventional clear glass, the emulsion opal glass color and luster is soft, and noble and unsullied grace is splendid, is high-grade glass decoration sheet material; Compare with crystallizing glass sheet material, the emulsion opal glass color and luster is beautiful, gracefulness, and can carry out heat processing technique such as hot bending and make, decapacitation is done outside the dalle, also can make the sanitary ware of different shape and the decoration ornaments of other moulding; And can satisfy the usefulness of the dalle of big specification.At present, little electric melting furnace is adopted in general emulsion opal glass production, and little electric melting furnace melted mass is very little, so can only produce widgets such as emulsion opal glass vessel, bulb, the dull and stereotyped finishing material piece of the emulsion opal glass of producing is little and thinner, the difficult demand that satisfies the dull and stereotyped emulsion opal glass of big specification, any thickness.Most critical be, can not control at present the volatilization of fluorine in the component in the technology preferably, the volatilization of fluorine can not effectively be controlled, emulsion opal glass ground quality just can't guarantee.
Summary of the invention:
The purpose of this invention is to provide a kind of method that adopts the continuous calendering method to produce emulsion opal glass sheet material, the emulsion opal glass sheet material that adopts this method to produce, specification is many, and thickness can be regulated arbitrarily, and production cost is low.
Technical scheme of the present invention is
1), the weight percent of the component of raw material is:
SiO
2 55～75 AL
2O
3 2～10 B
2O
3 0.3～3 CaO 2～8
MgO 0.1～0.5 ZnO 2.0～6 K

2O 5.5～15.7
F 3～9.25 As
2O
5 0.1～0.7 Sb
2O
5 0.01～0.3
2), above-mentioned raw materials is mixed in proportion, in glass melter, be heated to 1300 ℃～1550 ℃, be fused into glass metal;
3) glass metal is through cooling to 1350 ℃～1160 ℃, and adopting the rolling press calendering formation is the glass ribbon of desired thickness;
4) glass ribbon enters annealing furnace 700 ℃～600 ℃ temperature and carries out homo genizing annelaing;
5) glass ribbon after the annealing obtains emulsion opal glass sheet material through cutting, cut out, grind, throwing.
In the feed composition that the present invention adopts, improved the content of aluminum oxide and calcium oxide, aluminum oxide can generate more stable Na with fluorochemical
3AlF
6Thereby, effectively reducing the volatilization of fluorine, the raising of alumina content can effectively improve thermostability, chemical stability and the physical strength of glass, can prevent that also emulsion opal glass from producing the folding product.Calcium oxide can generate more stable Calcium Fluoride (Fluorspan) with the fluorine in the emulsion opal glass, thereby effectively reduce the volatilization of fluorine, calcium oxide is most important to the material of regulating emulsion opal glass, rolling process is produced emulsion opal glass and is required shaping speed fast, emulsion opal glass will have better cure state, so suitably improved the content of calcium oxide in the raw material of the present invention, the suitable rolling press that adopts carries out the continuous calendering moulding to glass metal, rolling press upper and lower roll spacing can be adjusted to desired thickness arbitrarily, so it is many to produce emulsion opal glass sheet material specification, thickness can be regulated arbitrarily.In addition, because of being continuous calendering, but also continuous production has just reduced production cost.
