Problems solved by technology

However, the thickness of about 90% of ceramic tiles is now 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 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 (AI 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 (Na2O): 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; after ball milling, pass through a 250-mesh sieve to form a sieve residue of 2-3% slurry;

[0030] C. Powder making: the slurry obtained in step B is dried in a spray drying to...

Embodiment 2

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

Abstract

The invention discloses a preparation process for an ultrathin ceramic brick. Blank raw materials comprise the following components in percentage by weight: 35-40% of clay, 25-30% of feldspar, 8-13% of lithium chinastone, 5-10% of aluminum ore and 15-20% of white sand; the preparation process comprises the following steps: preparing materials, pulping, preparing powder, forming and drying, biscuiting, glazing and printing, carrying out glaze firing, carrying out fine trimming and packaging. Through the adoption of the preparation process disclosed by the invention, the dosage of raw materials is reduced, the ball-milling time and sintering time are shortened to some extent, and the sintering temperature is reduced to some extent, so that sewage discharge, exhaust emission and consumption of energy and raw materials are reduced greatly and manpower resources are saved greatly.

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 now 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 greenhouse gases (carbon dioxide) and toxic gases (sulfur dioxide). ...
