Problems solved by technology

At present, the utilization degree of these waste residues is very low, and most of them are landfilled, resulting in the occupation of a large amount of cultivated land resources.
As a result, land and water are constantly polluted, and desertification-like consequences occur, so the use of polishing waste has become an urgent concern for governments and scientists
There are no related reports on the manufacture of large-scale lightweight porous ceramic plates using waste polishing residues from the building ceramics industry.

Embodiment 1

[0010] Add 50% of polishing waste, 23% of clay and 27% of sand and gravel into appropriate water glass composite debonding agent, sodium tripolyphosphate mixed with ball mill, remove iron from the mud, sieve, spray dry and granulate. The powder is pressed and formed by a 1050×2060mm super-sized double-mode press, with a pressing thickness of 7.3mm and a forming pressure of 32Pa. The water content of the dried green body is 0.2%. Then it is fired in a roller kiln at 1170°C, the firing cycle is 60 minutes, and the bulk density of the fired pressed product is 1.22g / cm 3 . The flexural strength is 19.8MPa, and the size after edging is 1000×2000mm. The finished product is finished after polishing and drying, and can also be cut and processed at will. It is an excellent wall decoration material.

Embodiment 2

[0012] Add 50% of polishing waste, 23% of clay and 27% of sand and gravel into appropriate water glass composite debonding agent, sodium tripolyphosphate mixed with ball mill, remove iron from the mud, sieve, spray dry and granulate. The powder is pressed and formed by a 1050×2060mm super-sized double-mode press, with a pressing thickness of 12.3mm and a forming pressure of 30MPa. The water content of the dried green body is 0.2%. Then it is fired in a roller kiln at 1195°C, the firing cycle is 85 minutes, and the fired pressed product has a bulk density of 0.85g / cm 3 . The flexural strength is 10.8MPa, and the size after edging is 1100×2100mm. The finished product is finished after polishing and drying. It can also be cut and processed at will. It can be used as heat insulation, sound-absorbing materials, wall decoration and wall materials.

Embodiment 3

[0014] Add 70% of polishing waste, 25% of clay, 5% of sand and gravel and 0.5% of silver-gray material into appropriate water glass and composite debonding agent, sodium tripolyphosphate mixed with ball mill, remove iron from the mud, sieve and spray Dry and granulate. The powder is pressed and formed by a 1050×2060mm ultra-large double-mode press, with a pressing thickness of 12.3mm and a forming pressure of 30MPa. After drying, the water content of the green body is 0.2%. Then it is fired in a roller kiln at 1185°C, the firing cycle is 85 minutes, and the fired product has a bulk density of 0.82g / cm 3 , after edging, the specification is 1100×2100mm, the surface is silver gray, and it becomes a finished product after polishing and drying, or you can choose to become a finished product directly without polishing. It can be used as a wall decoration material or as a sound-absorbing material, and has a good decorative effect.

Abstract

The invention discloses an ultra-large dimension light porous ceramic plate and a manufacturing method thereof. The invention uses waste materials and polished waste residues produced in the architectural ceramic industry as main raw materials, and the waste materials and the polished waste residues account for 50 to 80 percent in the material formula. The ultra-dimension light high-strength porous ceramic plate which maximally can reach 1200*2400mm is obtained by the way that the raw materials are pressed into forming by an ultra-dimension double molding press of 1050*2060mm and then the formed materials are monofired at the temperature of 1150 to 1210 DEG C. The formed powders can be mono-color or mixed color materials, and are dry pressed into forming by one time or multiple-time material application; and the sandstone-like decorative effect can be obtained with the seep curlicue technology. The firing temperature is at the range of 1150 to 1210 DEG C, and the product volume weight is between 0.7 to 1.5g / cm. The porous ceramic plate not only can be used as a novel wall decoration material but also as a functional material, and further can be used as a novel wall material to be widely used.

Description

technical field [0001] The invention relates to the technical field of porous ceramic plate production and manufacturing, in particular to a lightweight, high-strength super-large porous ceramic plate with wall decoration, heat insulation, sound absorption and other properties and a manufacturing method thereof. Background technique [0002] With the continuous progress of society, governments of various countries pay more and more attention to the sustainable development of economy and society, and their understanding of environmental protection is becoming more and more sufficient, and people's requirements for environmental protection are also increasing. In the production process of the building ceramics industry, in addition to discharging a large amount of waste gas and waste water, it will also produce a large amount of polishing waste. Taking a manufacturer of wall and floor tiles with an annual output of about 20 million square meters as an example, its annual output...
