Embodiment 1

[0019] A method for preparing sanitary ceramics from waste porcelain, comprising the steps of:

[0020] (1) Take sanitary ceramic waste porcelain, whose chemical composition is shown in Table 1. After crushing, roll mill for 18 hours, and the fineness is controlled at 0-2 μm, accounting for 15%, 2-10 μm, accounting for 60%, and 10-75 μm, accounting for 25%.

[0021] Table 1 Composition of sanitary waste porcelain from a sanitary ceramics factory in Chaozhou

[0022]

[0023] (2) Take black soil, Xikeng mud, and ball soil respectively. After crushing, according to the ball: material: water weight ratio of 1:1:1, ball mill for 3 hours, the fineness is controlled at 0-10 μm, accounting for 60%, and the largest grain The diameter is less than 250 μm. .

[0024] (3) The maximum particle size of albite and burnt talc after ball milling is less than 150 μm.

[0025] (4) Weigh 150g of waste porcelain powder, and other raw materials are weighed according to the mass ratio of wast...

Embodiment 2

[0029] The difference between this embodiment and embodiment 1 is:

[0030] The mass ratio of waste porcelain powder, albite, black clay, Xikeng mud, ball clay and burnt talc is 27:9:8:24:30:2.

[0031] The fluidity of the slurry is 39s, and the thickness is 1.6.

[0032] The main technical indicators of the product are as follows: the glaze surface is milky white, the whiteness value is 72, the base glaze is well bonded, the Vickers hardness is 602, and the water absorption rate is 0.47%.

Embodiment 3

[0034] The difference between this embodiment and embodiment 1 is:

[0035] The mass ratio of waste porcelain powder, albite, black clay, Xikeng mud, ball clay and burnt talc is 30:8:6:24:30:2.

[0036] The fluidity of the slurry is 34s, the degree of thickening is 1.5, and the firing temperature is 1200°C.

[0037] The main technical indicators of the product are as follows: the glaze surface is milky white, the whiteness value is 80, the base glaze is well bonded, the Vickers hardness is 591, and the water absorption rate is 0.61%.

Abstract

The invention discloses ceramic sanitary ware prepared from waste ceramic and a preparation method thereof and belongs to the filed of manufacture of ceramic. The preparation method comprises the following steps of: preparing waste ceramic sanitary ware powder, albite, black clay, West Pit cement, ball clay and burnt talc in a mass ratio of (25-35): (6-10): (3-9): (20-30): (25-35): (1-3), adding water glass accounting for 0.2-0.5% of the total mass of the above six raw materials, uniformly mixing and aging to obtain material slurry; and finally preparing the ceramic sanitary ware by using the material slurry. According to the preparation method, the waste ceramic and necessary auxiliary ceramic raw materials are used to prepare the ceramic sanitary ware; since the waste ceramic is sintered and contain lots of glass phase, the firing temperature is lowered, the energy consumption is reduced and the resource stress is relieved.

Description

technical field [0001] The invention relates to the field of ceramic manufacturing, in particular to a sanitary ceramic prepared by using waste porcelain and a method thereof. Background technique [0002] In the past 20 years, the ceramic industry has entered a stage of development with each passing day. With the extensive use of new technologies and new equipment, the output of ceramics has also increased significantly. While the output is soaring, the output of waste ceramics is also increasing. Taking Chaozhou Porcelain District as an example, the annual output of sanitary ceramics is more than 2 million tons, and the waste porcelain produced is more than 100,000 tons. Moreover, ceramic fragments are difficult to be weathered for thousands of years, are difficult to handle, and have high environmental protection costs. A large amount of ceramic waste not only makes enterprises a headache for how to deal with it, but also makes the government a big headache for its damag...
