Problems solved by technology

[0002] The current ceramic products are directly applied to the surface of the green body with ceramic color glaze, and are calcined at a temperature above 500°C. Defects such as glaze bubbles, and general manufacturers use to adjust the performance of the slip to reduce these defects. Due to the difference in raw material batches, it is difficult to accurately control the performance of the slip, resulting in reduced quality and high production costs.
Ceramic wine bottles belong to packaging containers, which have high requirements on product appearance. A flawed glazed wine bottle becomes a substandard product, which not only wastes resources, but also reduces corporate benefits, and does not meet the requirements of low-carbon and environmentally friendly production.

Embodiment 1

[0020] The method for preparing ceramic products by spraying mud on the middle layer comprises the following steps:

[0021] (1) The following raw materials are batched according to parts by weight, washed kaolin 40, Fujian porcelain stone 10, Suzhou soil 5, feldspar 18, glass powder 3, zinc oxide 8, lithium fluoride 0.2, special frit 15; Special frit is lead-free matt frit;

[0022] (2) The above-mentioned raw materials are put into the cylinder ball mill according to the proportioning: ball: water=1: 1.25: 1.25 weight ratio, and after 24 hours of ball milling, the cylinder is sieved to prepare the middle layer spray mud;

[0023] (3) Spray the middle layer spraying mud on the ceramic product body by spraying, after drying, enter the kiln for biscuit firing at a temperature of 1020-1050 ° C, and then apply glaze on the biscuit-fired blank, wait After drying, it is fired in a kiln.

Embodiment 2

[0025] The method for preparing ceramic products by spraying mud on the middle layer comprises the following steps:

[0026] (1) The following raw materials are batched according to parts by weight, washed kaolin 50, Fujian china stone 6, Suzhou soil 8, feldspar 10, glass powder 8, zinc oxide 5, lithium fluoride 0.8, special frit 10; Special frit is lead-free matt frit;

[0027] (2) the above-mentioned raw materials are put into the cylinder ball mill according to the proportioning of ingredients: ball: water=1: 1.35: 1.35, and through 30 hours of ball milling, the cylinder is sieved to prepare the middle layer spray mud;

[0028] (3) Spray the middle layer spraying mud on the ceramic product body by spraying, after drying, enter the kiln for biscuit firing at a temperature of 1020-1050 ° C, and then apply glaze on the biscuit-fired blank, wait After drying, it is fired in a kiln.

Embodiment 3

[0030] The method for preparing ceramic products by spraying mud on the middle layer comprises the following steps:

[0031] (1) The following raw materials are batched according to parts by weight, washed kaolin 45, Fujian china stone 8, Suzhou soil 7, feldspar 15, glass powder 4, zinc oxide 6, lithium fluoride 0.5, special frit 13; Special frit is lead-free matt frit;

[0032] (2) Put the above-mentioned raw materials into the cylinder ball mill according to the proportioning of ingredients: ball: water=1: 1.3: 1.3, after 26 hours of ball milling, go out of the cylinder and sieve to prepare the middle layer spray mud;

[0033] (3) Spray the middle layer spraying mud on the ceramic product body by spraying, after drying, enter the kiln for biscuit firing at a temperature of 1020-1050 ° C, and then apply glaze on the biscuit-fired blank, wait After drying, it is fired in a kiln.

Abstract

The invention belongs to the field of ceramic, and more specifically relates to a method used for preparing ceramic products with an intermediate layer spraying slurry. The intermediate layer spraying slurry comprises washed kaolin, Fujian chinastone, suzhou clay, feldspar, glass powder, zinc oxide, lithium fluoride, and a special frit. According to the method, the intermediate layer spraying slurry is sprayed onto ceramic bodies; the ceramic bodies are dried and are delivered into a kiln for biscuit firing at 1020 to 1050 DEG C; and then the ceramic bodies processed via biscuit firing are subjected to glazing, and are delivered into a kiln for sintering after drying. Binding ability of the intermediate layer spraying slurry with the ceramic bodies and coloured glaze is excellent; fineness of the intermediate layer spraying slurry is high; ceramic body pinholes and surface defects can be covered via spraying of the intermediate layer spraying slurry; glaze colour can be adjusted by adjusting the colour of the intermediate layer spraying slurry; product grade is increased; defective rate is extremely low; and production cost is reduced.
