[0022] Its manufacturing method comprises the following steps:

[0023] A. Add the raw materials calculated in the above ratio and 10% water of the total amount of raw materials into a ball mill to grind to a particle size of 40 μm to 45 μm, then remove iron from the slurry and sieve it, and spray dry it with a spray drying tower. Granules, stale for 48 hours, until the water content is 6.5%, and set aside;

[0024] B. Under the pressure condition of 180MPa, use a press to press the stale material in step A into a green body, and the green body is dried at a temperature of 200°C to obtain a brick, and the moisture content of the brick is controlled to 1%;

[0025] C. Spray glaze water on the surface of ...

Embodiment 2

[0027] This method of preparing true whole-body tiles includes raw materials of the following weights:

[0028] 40 tons of clay, 30 tons of kaolin, and 30 tons of stone rice; among them, the total aluminum content of raw materials is 18%, and the total iron content is 0.8%;

[0029] Its manufacturing method comprises the following steps:

[0030] A. Add the raw materials calculated in the above ratio and 10% water of the total amount of raw materials into a ball mill to grind to a particle size of 40 μm to 45 μm, then remove iron from the slurry and sieve it, and spray dry it with a spray drying tower. Granules, stale for 50 hours, until the water content is 7%, and set aside;

[0031] B. Under the pressure condition of 230MPa, use a press to press the stale material in step A into a green body, and the green body is dried at a temperature of 250°C to obtain a brick, and the moisture content of the brick is controlled to 0.5%;

[0032] C. Spray glaze water on the surface of ...

Embodiment 3

[0034] This method of preparing true whole-body tiles includes raw materials of the following weights:

[0035] 38 tons of clay, 28 tons of kaolin, and 34 tons of stone rice; among them, the total aluminum content of raw materials is 16%, and the total iron content is 0.5%;

[0036] Its manufacturing method comprises the following steps:

[0037] A. Add the raw materials calculated in the above ratio and 10% water of the total amount of raw materials into a ball mill to grind to a particle size of 40 μm to 45 μm, then remove iron from the slurry and sieve it, and spray dry it with a spray drying tower. Granules, stale for 52 hours, until the water content is 6.8%, and set aside;

[0038] B. Under the pressure condition of 200MPa, use a press to press the stale material in step A into a green body, and the green body is dried at a temperature of 220°C to obtain a brick, and the moisture content of the brick is controlled to 0.8%;

[0039] C. Spray glaze water on the surface o...

Abstract

The invention discloses a really-through ceramic tile preparation method. Really-through ceramic tiles are prepared from, by weight, 35-40% of clay, 25-30% of kaolin and 30-40% of gravel stone, and total aluminum content of raw materials is 14.5-18% while total iron content of the same is less than or equal to 1%. The method includes following steps: A, grinding the raw materials and water until granularity is 40-45um, spray-drying to form granules, and aging until water content is 6.5-7%; B, drying at temperature of 200-250 DEG C for forming, and controlling water content of tile blanks to 0.5-1%; C, spraying glaze water to the surfaces of the tile blanks, putting into a roller kiln, drying at a temperature interval of 200-400 DEG C, and feeding into a temperature interval of 1210-1220 DEG C for firing until water absorptivity is 1-3%. By the method, the problem that existing really-through ceramic tiles are poor in compression resistance and anti-freezing performance, high in water absorptivity, unitary in pattern color and poor in texture.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a method for preparing a full-body ceramic tile. Background technique [0002] True whole-body tiles are ceramic tiles with the same material and color on the front and back sides. The existing true whole-body ceramic tiles are made of natural stone as raw materials, and are prepared through production processes such as batching, ball milling, spray drying, high-pressure pressing and calcination, and the surface is not Glazing is directly polished, which has good anti-slip and wear-resistant properties; but the real whole body tiles prepared by the existing method have the following problems: 1. The raw material is natural stone, and there are many impurities without screening. Roughness and exposed pores lead to poor compression and frost resistance and high water absorption; 2. The color of natural stone is single, and the surface of the brick body is not ...
