Problems solved by technology

The degree of treatment and utilization of polished tile wastewater and waste residue is relatively low, and most of them are landfilled, resulting in a large amount of waste residue occupying cultivated land, polluting water and air, how to effectively treat waste has become a common concern of ceramic manufacturers and ceramic workers
Chinese patent CN1377859A discloses a method of using waste mud to produce lightweight ceramsite, but the products produced by this method have insufficient recycling of waste and narrow product applications; on the other hand, the development of modern buildings requires light weight and high strength. How to turn waste into treasure, turn waste into resources, and use vitrified brick polishing waste to produce light ceramic wall materials is the starting point of the present invention.

Embodiment 1

[0007] Add 50% of polishing waste, 12% of high-temperature sand, 18% of kaolin and 20% of low-temperature sand into 0.1% sodium hydroxymethyl cellulose and 0.2% sodium tripolyphosphate into the ball mill for wet ball milling, and the slurry passes through 250 Spray after sieving. The sprayed dry powder is pressed into shape with a pressure of 12M Pa, and fired at 1190°C. After firing, the product density is less than 700kg / m 3 , breaking strength > 800N, is an excellent lightweight building material.

Embodiment 2

[0009] 35% of polishing waste and 17% of high-temperature sand, 21% of kaolin and 27% of low-temperature sand are processed by wet ball milling with the method of embodiment 1, and the dry powder after spraying is divided into two layers of cloth with the dry powder obtained in above-mentioned embodiment 1 , pressed with 15M Pa pressure and fired at 1200°C. The surface of the product is polished, and the appearance effect is good and it also has the properties of a light-weight material.

Embodiment 3

[0011] 10% polishing waste and 27% high-temperature sand, 35% kaolin and 28% low-temperature sand are added with 0.5% manganese red material, the ball milling method is the same as in Example 1, and the dry powder cloth after spraying is placed on the bottom surface, and the surface of Example 1 The dry powder cloth in it is placed on the top, pressed with a pressure of 15M Pa, the surface is sprayed with a layer of high-temperature transparent glaze, and fired at 1200°C. After firing, the surface of the product is smooth, with good appearance and physical properties.

Abstract

The waste material collected from polish waste water and waste slag via deposition, press filtering and ageing is mixed with high temperature sand, kaolin and low temperature sand. The mixture is wet milled in a ball mill, 250-mesh sieved, iron eliminated and spray dried to form powdered material; the powdered material is dry formed into ceramic tile adobe in a ceramic press; and the ceramic tile adobe is baked in a roller hearth kiln at 1140-1200 deg.c in 40-75 min. The said method utilizes the waste reasonably and the product has excellent performance.

Description

technical field [0001] The invention relates to a production method of ceramic bricks, in particular to a production process for producing ceramic bricks by using waste materials in the ceramic industry itself. Background technique [0002] With the continuous progress of society, people's requirements for environmental protection are getting higher and higher. At present, the wastewater and waste produced by the polishing of a large number of vitrified tiles in the ceramic industry have a great impact on the environment. The degree of treatment and utilization of polished tile wastewater and waste residue is relatively low, and most of them are landfilled, resulting in a large amount of waste residue occupying cultivated land, polluting water and air, how to effectively treat waste has become a common concern of ceramic manufacturers and ceramic workers . Chinese patent CN1377859A discloses a method of using waste mud to produce lightweight ceramsite, but the products prod...
