Embodiment 1

[0052] [Example 1] Low-temperature rapid firing ceramic tiles and the first production process:

[0053] ⑴Collect the spare polishing waste slag to detect the moisture content, mix the ingredients according to the weight percentage, and convert it into a dry base blank formula: 65% polishing waste slag, 20% clay, 13% porcelain sand, 2% wollastonite; admixture: carboxymethyl fiber Sodium plain 0.08%, trimer 0.06%, sodium humate 0.03%, water glass 0.25%; put the ingredients into a ball mill, add water and wet grind into a slurry, the particles larger than 40 microns in the slurry are less than 2.30% (that is, the remaining 2.3% of the 325 mesh sieve ), after being sieved and iron-removed, it is stored in the slurry pool for later use.

[0054] ⑵ Spray drying to prepare powder, the moisture content of the powder is controlled at 6% to 7%, the bulk density is 0.98%, dry pressing is made into adobe of 330 mm×330mm, thickness 9.6 mm±0.3mm and dried, and the surface of the dried adob...

Embodiment 2

[0056] [Example 2] Low-temperature rapid firing ceramic tiles and the second production process:

[0057] (1) Mix 50% of polishing waste residue, 23% of clay, 17% of porcelain sand, 3% of wollastonite, 2% of bentonite, and 5% of high-temperature potash sand, and make pulp by ball milling; add 0.1% of sodium carboxymethyl cellulose, 0.2 %, wet ball milling into mud, the detection fineness greater than 40 microns is 2.14% (325 mesh sieve remaining 2.14%), the mud is transported to the spray tower after iron removal and sieving, and dried into powder for storage for later use;

[0058] ⑵Using the existing KD3800 hydraulic brick press in the production line, the powder is pressed into bricks with a specification of 600×600mm and a thickness of 10.0±0.3mm for drying, and the bottom glaze, surface glaze, and inkjet decoration are applied and conveyed by the multifunctional decoration line It is fired in a roller kiln at a firing temperature of 1140°C and a firing cycle of 60 minutes...

Abstract

The invention relates to a low-temperature fast-fired ceramic tile and a production process thereof. The blank material of the ceramic tile comprises at least one selected from the group consisting of fine granules produced during grinding and polishing in production of polished tiles, fine granule-containing waste water collected after polishing and a waste polishing material obtained after deposition and press filtration; the blank material of the ceramic tile is composed of, by weight, 48 to 73% of the waste polishing material, 5 to 20% of porcelain sand, 20 to 27% of clay and 2 to 5% of a mineralizer. The production process comprises the following steps: (1) collecting the waste polishing material, carrying out batching according to a formula and then carrying out wet ball milling so as to obtain slurry, wherein the waste polishing material stood for subsequent usage in press filtration and other raw materials are calculated on a dry basis; (2) subjecting the slurry to spray drying so as to obtain powder and carrying out dry-pressing so as to form a ceramic adobe; (3) drying the adobe, glazing the adobe and carrying out surface decoration; and (4) putting a decorated blank into a ceramic roller kiln for firing, wherein fast firing temperature is 1050 to 1140 DEG C, a firing period is 35 to 75 min, and the ceramic tile with a water absorption rate of less than 0.5% is sintered.

Description

technical field [0001] The invention relates to a low-temperature rapid firing ceramic brick and a production process. Background technique [0002] CN200410079020.9 discloses "a method for producing ceramic tiles by using polishing waste", and its purpose is to rationally reuse the polishing waste of vitrified tiles produced in large quantities in the ceramic industry. The technical solution: collect the waste water and waste slag produced after polishing vitrified tiles in the ceramic industry, and obtain polishing waste after sedimentation, pressure filtration and stale treatment. 10-70% of polishing waste, 10-35% high-temperature sand, 10- 35% of kaolin and 10-30% of low-temperature sand and gravel are mixed into the ball mill for wet ball milling, and the remaining 0.3-0.8% is passed through a 250-mesh sieve. After iron removal, the mud is sprayed with a spray tower for later use; The ceramic press is dry-pressed; the formed ceramic tile body is fired in a ceramic roll...
