Problems solved by technology

[0005] Traditional sandstone imitation ceramic products mostly follow the powder-making process of adding raw materials to water ball mill to make slurry, mud spray drying and granulation, and then use a dry granulator to spread the dry granules on the surface of the bricks after molding, and form a sandstone effect after firing. This method requires Specific dry granulation equipment and high-cost dry granules; or apply the glaze on the brick surface with the effect of imitating dry granules to form a similar sandstone effect, such as Chinese patent CN101497539A, this method requires additional introduction of glaze and control its Corresponding parameters, at the same time, the subsequent introduction of printing, flashing particles and other processes, the operation is more cumbersome; or use polishing waste residue, clay, sand and gravel as raw materials, through conventional powder making, molding, and firing processes such as water ball milling, spray drying and granulation Obtain the imitation sandstone effect, such as the Chinese patent CN101565311A, although this method utilizes part of the polishing waste, but its production process still uses the traditional process of adding water ball mill to pulp, sieve, spray drying, granulation and powder making process, and this powder making process The disadvantages are large energy consumption, large water consumption, serious environmental pollution, and long production cycle

Embodiment 1

[0030] The technological process and steps of the present embodiment are as follows:

[0031] (1) Raw material pretreatment. Dry and crush china clay, kaolin and lithium china stone so that the moisture content is 13% and the particle size is 1mm;

[0032] (2) Powder preparation. For the china clay, the pretreated china clay adopts a grinder with a heating device to grind and dry to obtain 20 to 40 meshes, which account for 40%, and the china clay powders which account for 60% and have a moisture content of 2% under 40 meshes are for subsequent use; Kaolin, the pretreated kaolin is ground and dried with a grinder with a heating device to obtain kaolin powder with 60-80 mesh accounting for 80%, 80 mesh or less accounting for 20%, and a moisture content of 1.5%, for subsequent use; for lithium porcelain Stone, the pretreated lithium china stone is ground and dried by a grinding machine with a heating device to obtain 60-80 mesh accounting for 90%, 80 mesh or less accounting fo...

Embodiment 2

[0040] The technological process and steps of the present embodiment are as follows:

[0041] (1) Raw material pretreatment. Dry and crush potassium feldspar and ball soil so that the moisture content is 12% and the particle size is 1.5mm

[0042] (2) Powder preparation. For potassium feldspar, the pretreated potassium feldspar is ground and dried with a grinder equipped with a heating device to obtain potassium feldspar powder with 20-40 mesh accounting for 70%, 40 mesh or less accounting for 30%, and a moisture content of 1%. For the ball soil, the pretreated ball soil is ground and dried by a grinder with a heating device to obtain 90% of the 60-80 mesh, 10% of the 80 mesh or less, and a moisture content of 1%. Powder, spare;

[0043] (3) Mixing. The prepared ball soil is pre-mixed with 1% orange material, and then the content of potassium feldspar is 80%, and the content of ball soil is 20%, and then mixed evenly in the mixer, and set aside;

[0044] (4) Granulation. ...

Embodiment 3

[0050] The technological process and steps of the present embodiment are as follows:

[0051] (1) Raw material pretreatment. Dry and crush albite, quartz sand, black mud and waste glass to make the moisture content 10% and the particle size 0.95mm;

[0052] (2) Powder preparation. For albite and quartz sand, the pretreated albite and quartz sand are ground and dried with a grinder with a heating device, and 20-40 mesh accounts for 55%, 45% for less than 40 mesh, and a moisture content of 1.5%. The albite and quartz sand powder materials are used for later use; for the black mud, the pretreated black mud is ground and dried by a grinder with a heating device to obtain 85% of 60-80 mesh, 15% of less than 80 mesh, and 15% of water content. The black mud powder with a ratio of 3% is reserved for use; for waste glass, the pretreated waste glass is ground and dried by a grinder with a heating device, and the obtained 60-80 mesh accounts for 87%, and the 80 mesh or less accounts fo...

Abstract

The invention discloses a method for producing a simulated natural sandstone ceramic product. The method comprises the following steps of: firstly preparing powder with moisture content less than or equal to 3%; then adding water for prilling so as to obtain molded granules with moisture content of 5%-7%; and preparing through a conventional method so as to obtain the product. During the firing process in a kiln, a fusing agent turns into liquid phase at a lower temperature and bonds aggregate in firing and a plastic material firmly, so that the strength of the finished stimulated sandstone ceramic product is further improved, the firing temperature of the product is lowered, and the stimulated sandstone ceramic product is in favor of being fired at a low temperature; after firing, the stimulated sandstone ceramic product is endowed with strong sandstone texture finally due to accumulated framework of the aggregate with thick particles.

Description

technical field [0001] The invention relates to the technical field of building ceramic production, in particular to a natural sandstone imitation ceramic product and a production method thereof. Background technique [0002] Natural sandstone is a rock that has been disintegrated into debris through weathering and denudation thousands of years ago, and then undergoes a series of physical and chemical reactions such as geological changes, layered deposition, and crustal deformation and extrusion. The mechanical sedimentary rock with high density and beautiful patterns formed by the long calcification cycle of ten thousand years. [0003] In recent years, sandstone, which is highly decorative, healthy and environmentally friendly, has a decorative effect of returning to nature due to its dense texture, colorful texture, and beautiful color patterns. Frequently used in the architectural decoration industry, more and more people are favored. [0004] However, as a natural mat...
