Problems solved by technology

However, the thickness of about 90% of ceramic tiles is 9-11mm. The larger the size, the thicker the thickness, the higher the firing temperature, and the longer the sintering time. This not only wastes a lot of raw materials and energy, but also emits a lot of energy. of greenhouse gases (carbon dioxide) and toxic gases (sulfur dioxide)

Embodiment 1

[0026] A preparation process of ultra-thin ceramic bricks is characterized in that it comprises the following steps:

[0027] A. Ingredients: Weigh raw materials by weight percentage: clay 35%, feldspar 30%, lithium china stone 13%, aluminum ore 7%, white sand 15%;

[0028] The chemical composition of lithium china stone powder is as follows: alumina (Al 2 o 3 ): 18.16%, silicon oxide (SiO 2 ): 69.15%, iron oxide (Fe 2 o 3 ): 0.05%, calcium oxide (CaO): 1.28%, magnesium oxide (MgO): 0.02%, potassium oxide (K 2 O): 3.63%, sodium oxide (Na 2 O): 2.65%, titanium oxide (TiO 2 ): 0.02%, lithium oxide (Li 2 O): 1.63%, loss on ignition: 2.91%;

[0029] B. Pulping: Mix and stir the materials in step A evenly, and ball mill the mixed raw materials according to the ratio of material: ball: water=1: 2: 0.5; pass through a 250 mesh sieve after ball milling to form a sieve residue of 2-3% slurry;

[0030] C. Milling: the slurry obtained in step B is dried in a spray drying tower ...

Embodiment 2

[0041] The raw material composition of the billet: 40% of clay, 25% of feldspar, 8% of lithium china stone, 10% of aluminum ore, and 17% of white sand; other steps are the same as in the first embodiment.

Embodiment 3

[0043] The raw material composition of the billet: 37.5% of clay, 27.5% of feldspar, 10.5% of lithium china stone, 7.5% of aluminum ore, and 17% of white sand; other steps are the same as in the first embodiment.

Abstract

A preparation process for ultra-thin ceramic bricks. The raw material of the blank is composed of 35-40% clay, 25-30% feldspar, 8-13% lithium china stone, 5-10% aluminum ore, and 15-20% white sand. %, including batching, pulping, powder making, forming and drying, biscuit firing, glaze printing, glaze firing, finishing packaging and other steps. The amount of raw materials used in the process of the invention is reduced, and the ball milling time, firing temperature and firing time are all shortened to a certain extent, resulting in great savings in sewage discharge, waste gas discharge, energy and raw material consumption, and human resources.

Description

technical field [0001] The invention relates to the technical field of preparation of building decoration materials, in particular to a preparation process of ultra-thin ceramic bricks. Background technique [0002] With the deepening of my country's reform and opening up, the output of ceramic tiles has been ranked first in the world for many years since the 1990s, much higher than the output of other countries in the world. As the specifications of ceramic tiles become larger and larger, the thickness becomes thicker and thicker, and the consumed raw materials, mineral resources, energy and other resources increase in proportion to the thickness. However, the thickness of about 90% of ceramic tiles is 9-11mm. The larger the size, the thicker the thickness, the higher the firing temperature, and the longer the sintering time. This not only wastes a lot of raw materials and energy, but also emits a lot of energy. greenhouse gases (carbon dioxide) and toxic gases (sulfur dio...
