Problems solved by technology

However, due to the use of the secondary firing production process, its total cycle is more than four hours (that is, the production cycle is long), so the production cost of the product is relatively high, especially in the aspect of high energy consumption, which is more prominent; In recent years, affected by the rising cost of materials, labor, energy, etc., the profit margin of this product has been squeezed
To sum up, the deficiencies, defects and disadvantages of this existing known technology are: the process of secondary firing is cumbersome, irregular, long cycle, high energy consumption, labor and time-consuming, low production efficiency, strong randomness in material selection, Product quality is not stable

specific Embodiment approach 1

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings. As shown in the accompanying drawings:

[0038] A production method of one-time fired transparent glass and overglaze color ceramic composite board:

[0039] ①. Preparation of transparent frit dry granules: 80-700 kg each of quartz, potassium feldspar, albite, calcite, talc, dolomite, barium carbonate, sodium carbonate, potassium carbonate, borax, and boric acid with a thickness of less than 100 mesh, And choose 100 kg of one of sodium chloride, sodium sulfate, and fluorite with a thickness less than 100 meshes as a clarifying agent; mix the above as frit raw materials evenly, and send the uniformly mixed frit raw materials into the glass tank kiln Melting, the melting temperature is 1520-1600 °C; after water quenching, drying, crushing and screening of the melted melt, the obtained composition range is SiO 2 50-70%, Al 2 o 3 5-20%, CaO0-10%, MgO0-10%, K 2 O+Na ...

specific Embodiment approach 2

[0060] Carry out by specific embodiment one, just as shown in the accompanying drawing of description, just:

[0061] 1. In the preparation of the transparent frit dry granules of ①: quartz, potassium feldspar, albite, calcite, talc, dolomite, barium carbonate, sodium carbonate, potassium carbonate, borax, boric acid with a thickness of less than 100 mesh Proportion raw materials, and choose one of sodium chloride, sodium sulfate, and fluorite as a clarifying agent, weigh 2000 kg per batch, mix the above as frit raw materials evenly, and send the uniformly mixed frit raw materials into Melting is carried out in a glass tank kiln, and the melting temperature is 1520-1600°C; after the melted melt is water quenched, dried, crushed, and sieved, the composition range obtained is SiO 2 5 0-70%, Al 2 o 3 5-20%, CaO 0-10%, MgO 0-10%, K 2 O+Na 2 O 2-8%, BaO 0-8%, B 2 o 3 0-8%, clarifier 1-10%, 20-200 mesh and moisture<0.5% transparent frit dry granules. The respective dosages ...

specific Embodiment approach 3

[0064] Carry out by specific embodiment one, just as shown in the accompanying drawing of description, just in the preparation transparent frit dry granule of described 1.: the composition of the transparent frit dry granule set in advance is by SiO 2 57.20%, Al 2 o 3 10.62%, CaO 7.20%, MgO 5.12%, K 2 O+Na 2 O is 4.72%, BaO is 4.13%, B 2 o 37.26% for clarifier and 3.75% for clarifying agent. Select the corresponding proportion of quartz, potassium feldspar, calcite, dolomite, soda ash, barium carbonate, boric acid, and nitric acid under the pre-set dry product composition of transparent frit. Potassium, and add an appropriate amount of clarifying agent for batching. Mix in a mixer for 30 minutes, melt in a pool kiln of 22 square meters, the melting temperature is 1580°C, and the storage time is about 24 hours. The clarified melt is water quenched, dried, crushed, and sieved , to obtain 20-200 mesh transparent frit dry granules. Also received the expected effect.

Abstract

A method for producing transparent glass and overglazed color ceramic sandwich by single firing in the invention relates to the technical field of building materials. By the adoption of ''a key single firing technology with material selection within the range of predetermined product components'', the method provided by the invention comprises the following steps of: applying ground-coat enamel on a ceramic green compact to prepare an enamel green body, printing gelatine-pad printed fancy glaze to prepare an overglazed color ceramic green body, applying transparent frit dry granules on the overglazed color ceramic green body to prepare overglazed color frit dry granular ceramic green body, spraying methyl cellulose for fixation to prepare a greenware to be sintered, sintering the greenware to be sintered to form a semi-finished product, followed by strickling for thickness determination, rough casting, fine casting, edging, chamfering, air drying, picking and grading to prepare the transparent glass and overglazed color ceramic sandwich finished product. The method is used for the production of transparent glass and overglazed color ceramic sandwiches and is the single firing technology with material selection within the range of predetermined product components.

Description

technical field [0001] The invention discloses a production method of once-fired transparent glass and overglaze ceramic composite board, which relates to the technical field of building materials; in particular, to the technical field of glass ceramic building materials; especially to the technical field of production methods of glass-ceramic building material products; specifically, to the technical field of once-fired transparent glass The technical field relates to a production method of an overglaze color ceramic composite plate. Background technique [0002] In the process of making glass-ceramic composite panels, that is, in the production process of transparent glass and overglaze ceramic composite panels, raw materials such as frit, ceramic green body, bottom glaze and printing glaze are inseparable. The frit, ceramic green body, bottom glaze are prepared and the printing glaze is prepared, and then these raw materials are used to apply the bottom glaze to the ceram...
