Background
With the gradual exhaustion of mineral raw materials, world energy supply is becoming more and more intense, energy crisis is now at the beginning, energy price is rising, and production cost is greatly increased. Each industry takes effective measures to save energy and reduce consumption to the greatest extent, and the ceramic industry is a large household of energy consumption, and has a large proportion in the consumption of economic energy, so that the reduction of the energy consumption in the ceramic production process is a long-term important task of the ceramic industry.
In the building ceramic technology, the reduction of the firing energy consumption is an important link in reducing the production cost and improving the economic benefit; the basic method for reducing the sintering temperature of the green body is to realize the low-temperature sintering of the green body. The existing ceramic tile with low water absorption rate (namely ceramic tile blank with water absorption rate less than or equal to 0.5%) is generally baked at 1180-1250 ℃, which not only consumes a great deal of energy and mineral products, but also makes the production cost of the ceramic tile blank relatively high.
In addition, the ceramic tile product with low water absorption rate can generate a large amount of waste materials such as cinder, waste glaze slag, sewage filter pressing mud, polishing waste slag and the like in the production process, and the ceramic waste materials can swell and foam at high temperature, and a small amount of the ceramic waste materials are mixed into ceramic blanks to cause fatal defects of the product, so that the ceramic waste materials cannot be recycled in the blanks for a long time. Most ceramic product manufacturers adopt a landfill mode to treat the waste, so that the treatment cost is increased, the production cost of ceramic products is increased, the land is occupied, and the environment is polluted. There are also a small number of ceramic product manufacturers who utilize one or both of the waste materials for recycling and for use in the production of ceramic tiles, but the remainder of the waste materials are still disposed of in landfills with limited recycling of the waste materials.

Detailed Description
The low-water-absorption ceramic tile prepared by utilizing the ceramic waste comprises powder A and powder B, wherein the addition amount of the powder A is 30-70% by mass percent;
according to the mass percentage, the powder A comprises 10-50% of polishing waste residue, 5-30% of cinder, 0-20% of ironmaking waste residue, 20-40% of high Wen Jia sand, 5-15% of bentonite I and 10-20% of A pug;
according to the mass percentage, the powder material B comprises 1 to 10 percent of waste glaze slag, 1 to 10 percent of sewage filter pressing mud, 2 to 20 percent of ceramic waste bricks, 10 to 20 percent of medium Wen Jiasha, 15 to 25 percent of albite, 1 to 10 percent of magnesia, 1 to 6 percent of talcum, 1 to 5 percent of wollastonite, 1 to 10 percent of bentonite II and 15 to 25 percent of B mud.
In order to consume a large amount of waste generated in the production process of the low-water-absorption ceramic tile product and reduce the treatment cost of the ceramic waste, the technical scheme provides the low-water-absorption ceramic tile prepared by utilizing the ceramic waste, which mainly utilizes five ceramic waste materials of polishing waste residues, coal cinder, waste glaze slag, sewage filter pressing mud and ceramic waste bricks as main production raw materials and is matched with iron-making waste residues in the iron smelting industry, so that the ceramic tile with low water absorption can be effectively prepared, the circulation of the waste in the production process of the low-water-absorption ceramic tile is realized, the sintering energy consumption in the preparation process of the ceramic tile can be reduced, and the defects in the prior art are overcome.
It should be noted that the polishing waste residue is a relatively common waste material in the field of building ceramics, is mainly generated in the grinding and polishing processes of ceramic bricks, and mainly comprises silicon carbide, magnesium oxide, magnesium chloride, brick scraps and the like in the grinding blocks.
The cinder is a solid waste material generated in the ceramic tile firing process, the generated amount is large, and about 0.35 ton of cinder is generated after 1 ton of coal is combusted. The cinder contains a large amount of SiO 2 、Al 2 O 3 、Fe 2 O 3 And CaO, and a small amount of residual heat value, so that the application of the recycled cinder in the ceramic body formula is researched, the consumption of traditional raw materials is reduced, more and better waste cinder can be utilized, the recycling of waste is realized, and the method is beneficial to saving the cost and protecting the environment.
In addition, in the production process of ceramic bricks, a certain amount of waste glaze water is generated by glaze production, ball washing and cleaning equipment in a ball glaze workshop, glaze dripping and the like in the production process of a glaze line, and waste glaze slag is generated after the waste glaze water is subjected to precipitation and squeezing treatment. The waste glaze slag has glaze property but is mixed with other components, so that the waste glaze slag is difficult to be applied to the production of high-quality ceramic tile products in the form of glaze. And the firing temperature of the waste glaze slag is low, the low-temperature melting raw materials are more, the high-temperature melting degree is high, and the high-temperature viscosity is low, if the waste glaze slag is directly applied to blanks, the liquid phase generation amount is easily increased when the blanks are fired, so that the brick shape and the moire of the kiln-exiting bricks are not easy to control.
The sewage filter-pressing mud is mud left after the ceramic factory bed charge, the surface material cleaning pulp tank and the spray tower are cleaned and are subjected to secondary treatment by a sedimentation tank and are extruded by a filter press, and the mud is generally discarded in the prior art.
The ceramic waste bricks generally comprise two kinds, namely, unrenewable unqualified products which are generated and found in the firing process, the processing process and the product inspection process of the ceramic bricks, and leftover materials which are obtained by trimming the ceramic bricks in order to ensure that the right angle and the edge straightness of the ceramic brick finished products are in a proper range in the actual production process of the ceramic bricks.
Specifically, the low-water-absorption ceramic tile prepared from the ceramic waste material comprises powder A and powder B.
Firstly, according to the mass percentage, the powder A in the scheme comprises 10-50% of polishing waste residue, 5-30% of cinder, 0-20% of ironmaking waste residue, 20-40% of high Wen Jia sand, 5-15% of bentonite I and 10-20% of A pug. Because the ceramic waste in the powder A has the characteristics of easy oxidization and foaming at high temperature, in order to prevent the formula system from melting before gas is not completely discharged, so that pores are closed and cannot be smoothly discharged and/or are discharged suddenly, pinholes, bubbles and even bulges are generated on the surface of a sintered blank body. In addition, the polishing waste residue and the iron-making waste residue in the raw materials have rich calcium, magnesium and iron components, so that the introduction of other low-temperature fluxes such as sodium, titanium, barium, zinc and the like in the formula is reduced on the basis of fully utilizing the fluxing effect of the components, and the purpose of widening the sintering range of the powder A is achieved.
Secondly, according to the mass percentage, the powder B in the scheme comprises 1 to 10 percent of waste glaze slag, 1 to 10 percent of sewage filter pressing mud, 2 to 20 percent of ceramic waste bricks, 10 to 20 percent of medium Wen Jiasha, 15 to 25 percent of albite, 1 to 10 percent of magnesia, 1 to 6 percent of talcum, 1 to 5 percent of wollastonite, 1 to 10 percent of bentonite II and 15 to 25 percent of B mud. Because the ceramic waste in the powder B has the common point of no foaming at high temperature and the loss on ignition of the waste glaze slag is low, the components such as calcium, magnesium, potassium, sodium and the like can be introduced into the formula system by adding the medium-temperature potassium sand, the albite, the magnesia, the talcum, the wollastonite, the bentonite and the pug into the formula system of the powder B, so that the low-temperature co-melting effect of the formula system of the powder B is realized. In addition, the chemical components of bentonite I in powder A and bentonite II in powder B in the scheme can be the same or different, and I and II are only used as distinguishing marks.
Finally, mixing the powder A and the powder B which can realize the low-temperature co-melting effect according to a proportion to prepare the ceramic tile. The whole temperature of the blank formula after low-temperature co-melting is low, so that the temperature of the kiln is reduced, the exhaust of the kiln can be increased after the temperature of the kiln is reduced, and the oxidation is facilitated and the energy consumption is saved. In addition, due to different kiln structures, the oxidation capability provided by the kiln structures is different, and the proportion of the powder A and the powder B in the scheme is limited, so that the kiln structure of the existing low-water-absorption ceramic tile can be used for preparing the low-water-absorption ceramic tile by utilizing the ceramic waste, the kiln structure of the existing low-water-absorption ceramic tile is not required to be adjusted, the low-water-absorption ceramic tile can be prepared by utilizing the ceramic waste, and the equipment adjustment cost is saved.
The low-water-absorption ceramic tile prepared from the ceramic waste adopts the ceramic waste as the main raw material, iron-making waste residues in the iron smelting industry are added, the raw materials are easy to obtain, the production cost is low, a large amount of land can be saved after recycling, and environmental protection is realized. Further, by adjusting the formula, the energy consumption for sintering the ceramic tile in the production process is reduced on the premise of meeting the related performance.
Further, the mixing ratio of the polishing waste residue to the cinder is 1: (0.2-0.5).
Since the silicon carbide component in the polishing waste residue is oxidized at a high temperature, silicon dioxide is strongly generated and carbon dioxide is evolved, thereby generating a large amount of bubbles. In a preferred embodiment of the present technical solution, the mass ratio of the polishing waste residue to the cinder is preferably 1: (0.2-0.5) to form a certain reducing atmosphere in the interior micro space of the spray powder particles by utilizing the strong reducing property of the high-temperature solidified carbon element remained in the cinder, and play a role in preventing the silicon carbide component in the polishing waste residue from violent oxidation reaction at high temperature, so that the product is completely sintered at low temperature, the surface of the blank body is not foamed, and the compactness of the blank body structure is not damaged.
Further described, the Al of the cinder, calculated as mass percent 2 O 3 The content is 37-40%;
the melting temperature of the Gao Wenjia sand is 1130-1180 degrees, the melting temperature of the polishing waste residue is 800-850 degrees, and the melting temperature of the ironmaking waste residue is 1000-1150 degrees.
Because the ceramic waste in the powder A has the characteristics of easy oxidization and foaming at high temperature, in order to ensure the sufficient discharge of gas, the scheme further optimizes the melting temperature of the ceramic waste in the powder A and the melting temperature of Wen Jiasha matched with the ceramic waste in the powder A, and improves the initial melting temperature of the eutectic melting of the powder A, increases the oxidization time and discharges the gas by introducing potassium sand with higher melting temperature.
Still further, the A-sludge includes any one of stucco and white mud.
Further, the melting temperature of the medium-temperature potassium sand is 1000-1050 degrees.
