Embodiment

[0021] Examples: (1) Kiln design and production

[0022] The kiln includes a kiln body, a kiln car, a heating gun, an exhaust chimney, and a temperature detector;

[0023] The heating gun is connected to the LPG pipeline and uses LPG as heating energy; the exhaust chimney is used for the exhaust gas of the kiln, and the temperature detector is used to detect the temperature; the kiln car is equipped with a kiln plate (heat-resistant spar kiln plate) for supporting glass Ceramic plate painting

[0024] (2) Baked color

[0025] A. Place 12 square meters (length 6 meters, width 2 meters) single-sided large-scale glass ceramic plate painting on the kiln plate of the kiln car, the glass ceramic plate painting face up, the non-color painting side Face down

[0026] B. Push the kiln car with glass ceramic plate painting into the kiln body;

[0027] C. Ignite the heating gun to heat the kiln; the first heating time of the kiln is 61 hours, and the maximum temperature is controlled between 745℃...

Abstract

The invention discloses a large-sized glass ceramic board painting color baking process. The large-sized glass ceramic board painting color baking process is characterized by comprising the following steps of 1 kiln designing and making and 2 color baking. According to a large-sized glass ceramic board painting made through the method, the board painting is smooth and is not subjected to deformation, the surface of the painting is settled in a glass ceramic board, the painting surface bareness phenomenon does not exist, the painting surface is clear, glittering, translucent and appearance, and the yield of products in the making process reaches 100%.

Description

Technical field [0001] The invention relates to the field of glass and ceramics, in particular to a baking process for large-format glass ceramic plate paintings. Background technique [0002] Glass ceramics, also known as glass-ceramics, is defined as "a type of composite material composed of a crystalline phase and a glass phase, which is generally obtained by appropriately heat-treating the glass to produce sufficient microcrystalline phases in the glass." [0003] The biggest difference between the glass ceramic plate and the ceramic plate is that the internal and external materials of the glass ceramic plate are the same. The ceramic plate is made of clay-fired porcelain on the lower layer and pure enamel on the upper layer. There are big differences in the materials and baking process of its surface painting. In addition to the unique craftsmanship, the baking color of the glass ceramic plate painting must also control the temperature to prevent the internal crystals of the ...
