Abstract
The invention relates to a bright red glass producing process, mainly comprising the steps of: 1.1) batching SiO2 40-70 weight shares; Al2O3 0.5-3.0 weight shares; Sn 0.35-0.1 weight share; K2O 0.5-10 weight shares; Na2O 0.5-19 weight shares; ZnO 5.5-10 weight shares; B2O3 0.5-3 weight shares; and CdO 0.5-3 weight shares; 1.2) uniformly mixing them and casting their mixture into a ceramic pot and sealing the pot and firing in a closed kiln; 1.3) forming the required blanks by the selected mould and breaking trimmings, shaping and graded-screening; 1.4) casting the selected blanks into a coloring furnace and heating and strictly controlling the temperature to be 450-650 deg.C and the heating time to be 5-15 min, and finally making their temperatures reach glass softening region until they become bright red. And it has beneficial effects of: stable quality of product, less raw material waste and more applied to industrialized production.
Description
Technical field
The present invention relates to the process of glass field, mainly is a kind of bright red glass producing process.
Background technology
Bright red glass is the making material of artistic glassware and glass.What sold existing domestic market is Korea-invested enterprise produced or adopted spray colouration with Korea S's technology handicraft product.Former bright red glass of producing as developing technology of tinting material with gold is difficult to standard because of technological operation, and it is many artificially to reach environmental impact factor, and glass reason such as very easily be magnetized causes the glass color difference phenomenon serious, unstable product quality in the art production process.Waste material is overstocked many simultaneously, and raw materials consumption is big, especially precious metal--and the consumption of-Jin increases, and causes the production cost height, is not suitable for industrialization production.
Xian Se production technique (technical process is illustrated as Fig. 1) once: be various raw materials to be uniformly mixed to form compound by formulation ratio (weight ratio) requirement drop into vitrified pot and seal, in the stove of sealing, fire, heating and temperature control is at 1480-1520 degree centigrade, fire after 7 hours stove and stop heating, then open fire door and crucible seals, glass solution in the crucible is manually stirred material, and discharge surface material slag.When treating that the feed liquid naturally cooling shows large red in the crucible, feed liquid is chosen the shape embryo (work in-process) of making required handicraft through selected mould by modes such as roll extrusion or crowded tension and compression.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, and a kind of steady quality and the low bright red glass producing process of production cost are provided.
The present invention realizes the technical scheme that above-mentioned purpose adopts.This bright red glass producing process, key step is as follows:
1.1), raw material is by following weight proportion: SiO
240-70 part; Al
2O3 0.5-3.0 part; Sn 0.35-0.1 part; K
2O 0.5-10 part; Na
2O 0.5-19 part; ZnO 5.5-10 part; B
2O
30.5-3 part; CdO 0.5-3 part;
1.2), various raw materials required to be uniformly mixed to form compound in proportion drop into vitrified pot, and seal in the stove of sealing and fire, heating and temperature control is at 1480-1520 degree centigrade, fires after 7 hours stove and stops heating and open fire door and crucible seals, and manually stirs material and deslagging;
1.3), when treating that feed liquid naturally cools between 1050--1150 degree centigrade in the crucible, feed liquid is chosen, form the blank of required handicraft through selected mould, in natural cooling process, again blank is broken burr, shaping, sizing screening;
1.4), the blank that will select drops into coloring furnace and heating, and strict controlled temperature is at 450-650 degree centigrade, 5-15 minute heat-up time, when making the blank temperature reach the softening zone of glass at last to be bright red colour developing till.
The effect that the present invention is useful: the production technique working specification is grasped easily, glass can not produce magnetization in process of production, avoid taking place variegated and the aberration phenomenon, constant product quality, starting material loss less wastage, especially the usage quantity of gold can reduce 30-35%, reduces production costs, and more adapts to industrialization production.
