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
Utilize the waste polishing slag from the building ceramic industry to manufacture heat insulation, fire prevention, sound absorption and other properties with a volume density as low as 0.45-0.7g / cm 3 Lightweight ceramic plates have not yet seen relevant reports

Embodiment 1

[0013] Add 54% of polishing waste, 23% of clay, 20% of sand and gravel, and 3% of auxiliary agents into appropriate water glass, composite debonding agent, and sodium tripolyphosphate mixed with ball mills. The slurry is iron-removed, sieved, and then sprayed. Dry and granulate. The powder is pressed and formed by a 1050×2060mm super-sized double-mode press, with a pressing thickness of 9mm and a forming pressure of 32MPa. The water content of the green body after drying is 0.35%, and a layer of high-temperature transparent glaze is applied on the surface, and then it is fired in a roller kiln at 1202 ° C, and the firing cycle is 68 minutes. The bulk density of fired pressed products is 0.69g / cm 3 , the flexural strength is 8.8MPa, the water absorption rate is less than 3%, and the finished product is finished after grinding and drying. The product specification is 1000×2000mm, and it can also be cut and processed at will. It is an excellent building material.

Embodiment 2

[0015] Add 90% of polishing slag, 8% of clay, 2% of auxiliary agent, and 0.3% of green body strengthening agent into appropriate water glass, composite debonding agent, sodium tripolyphosphate mixed ball mill, and remove iron from the mud and sieve it Granulated by spray drying. The powder is pressed and formed by a 1050×2060mm ultra-large double-mode press, with a pressing thickness of 12mm and a forming pressure of 30MPa. After drying, the moisture content of the green body is 0.4%, and then it is fired in a roller kiln at 1205°C, with a firing cycle of 100 minutes, and the fired pressed product has a bulk density of 0.66g / cm 3 . The flexural strength is 8.6MPa, and the water absorption rate is less than 3%. The finished product is finished after grinding and drying. The product specification is 1100×2100mm. It can also be cut and processed at will. It can be used as heat insulation, sound-absorbing materials and non-load-bearing wall materials. use.

Embodiment 3

[0017] 59% of the polishing waste, 23% of the clay, 14% of the gravel material, and 4% of the auxiliary agent are mixed with water glass, compound debonding agent, and sodium tripolyphosphate for ball milling, and the slurry is iron-removed and screened. Spray drying and granulation. The powder is pressed and formed by a 1050×2060mm ultra-large double-mode press, with a pressing thickness of 11.3mm and a forming pressure of 30MPa. The water content of the green body after drying is 0.4%, and then it is fired in a roller kiln at 1200°C, and the firing cycle is 92 minutes. The bulk density of fired products is 0.58g / cm 3 , the flexural strength is 6.9MPa, and the water absorption rate is less than 3%. The product becomes a finished product after edging and drying, and the product specification is 1100×2100mm. It can be used as thermal insulation material for interior and exterior walls, and can also be used as sound-absorbing material for building houses and non-load-bearing w...

Abstract

The invention discloses a production method of low-volume-weight light-weight ceramic plank stuff. The ceramic plank stuff is produced after high-temperature sintering at 1170-1220 DEG C, the maximal size thereof can reach 1100 multiplied by 2100 and the volume weight is 0.45-0.7g / cm. The production method is characterized in that the raw materials contain 54-90 percent of polished waste residue, 7-30 percent of clay, 0-20 percent of sandstone materials, 2-10 percent of auxiliary agent, 0-1.2 percent of billet reinforcing agent and 0.3-1.5 percent of dispergator; the auxiliary agent is one or the combination of a plurality of CaCO3, MgCO3, steatite, waste fusion cakes, waste glass, carborundum powders and carbon black. The production is a ceramic body with a micropore structure and has the functions of light weight, high strength, heat insulation and preservation, fireproofness, sound absorption, and the like, thereby being an environment-friendly novel building material. The low-volume-weight light-weight ceramic plank stuff can be used as building non-bearing wall materials, heat insulating materials of internal and external walls, sound insulation materials of buildings or besides highways and also can be used as an artificial floating island.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a method for manufacturing a low-volume lightweight ceramic plate with properties such as light weight, heat insulation, fire prevention, and sound absorption, and belongs to the field of new building materials. 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 addition to discharging a large amount of waste gas and waste water during the production process, the architectural ceramics industry also produces a large amount of polishing waste. The ceramic polishing waste generated in China's ceramic production areas reaches as much as 10 million tons every year...
