The production process sequentially comprises the following steps: 1, weighing raw materials; 2, mixing the raw materials evenly, preheating, and then melting in a tank furnace, so as to obtain liquid glass; 3, molding by a die; 4, carrying out first artificial finishing after cooling; 5 feeding the product subjected to first artificial finishing to an annealing furnace for annealing, and then slowly cooling to room temperature; and 6 carrying out second artificial finishing after cleaning with pure water, and then cleaning with pure water again. In practical use, the high-quality glass can be fabricated by adopting the glass production process disclosed by the invention.
Description
Technical field
The present invention relates to inorganic amorphous technical field of material, particularly relate to a kind of production technique of high-quality coloured glaze.
Background technology
Coloured glaze is a kind of silicate product, has a long history, and its quality is glittering and translucent, bright and glittering, changes irregularly magnificent, and fully demonstrate the exquisiteness of Oriental, exquisiteness and implicit, be a kind of important decoration element, the main component of coloured glaze is SiO
2.(i.e. silicon-dioxide), aluminum oxide, fusing assistant plumbous oxide and pigment etc.
Coloured glaze composition is low with softening temperature, material property length for there being good characteristic, be so convenient to manufacture technics, be applicable to coloured glaze be shaped, the quality of colored glaze product is embodied in good luster, and bubble, striped, calculus are few.The softening temperature of coloured glaze, material property depend primarily on the kind of composition and ratio thereof in coloured glaze formula, and in coloured glaze basic ingredient, add finings can make that coloured glaze temperature of fusion reduces, refining quality is improved, and avoid producing the defects such as bubble, striped, calculus.Finings can release decomposition gas in coloured glaze production process, or self gasification, produces a large amount of bubbles, receives the small bubbles of periphery, promote that coloured glaze is clarified with blub rises.Finings conventional at present has cerium dioxide, white arsenic etc., but white arsenic is highly toxic substance, threatens operator ' s health and serious environment pollution; The clarifying effect of cerium dioxide still can, but settling time is longer, and cerium is rare earth element, and cost is costly.Therefore the coloured glaze formula that a kind of softening temperature is low, material property is long, clarifying effect is good, settling time is short, product property is excellent is needed badly.
Patent documentation CN201210526726.X, publication date 2013.03.06, disclose a kind of light color terra-cotta for building, described light color terra-cotta for building are in every kilogram of magnesium chloride solution, add 0.4-0.6kg magnesium oxide, stir 6-8 minute, then 0.05-0.1kg Magnesium Silicate q-agent is added successively, 0.02-0.03kg urea-formaldehyde resin, 0.06-0.1g volatile salt, 2-3g tertiary sodium phosphate and 2-3g colorant, stir 20-30 minute, then the material be stirred is poured on glasscloth, strike off compacting, obtain after spontaneous curing drying, by the way, , light color terra-cotta smooth surface for building is clean and tidy, bright in colour beautiful, will never fade, there is excellent anti-folding and anti-pressing, resistance to rapid heat cycle, acid-proof alkaline and frost resistance energy, quality is light, water-intake rate is low, and insulation and soundproof effect good, cost is low.But at present about being applicable to prepare azure stone handicraft, colory coloured glaze formula report is less.
