Abstract

The invention discloses a formula and a method for manufacturing ceramic tile blank bodies by utilizing polished waste residues. The formula adopts ingredients by weight portions: porcelain clays account for 18 to 40 parts, clays account for 20 to 30 parts, limestone grains account for 1 to 10 parts, wollastonite grains account for 3 to 15 parts, glazed tile sludge residues account for 3 to 10 parts, ceramic polished waste residues account for 15 to 45 parts, soluble glass accounts for 1 to 2 parts, thinners account for 0.15 to 0.4 parts, sodium tripolyphosphate accounts for 0.05 to 0.2 parts, and a proper amount of water is adopted. A manufacturing method of the ceramic tile blank bodies comprises the steps as follows: a. raw materials are put in a ball grinder for ball milling after being blended so as to form sizing agents with proper fineness and screen tailings through milling, and the sizing agents are processed through deferrization, sieving and spray drying so as to form powders; and b. the powders are put in a die cavity of a press forming machine to form waterish blanks through pressing, the waterish blanks are dried in a drying kiln, the dried waterish blanks are applied with base pulp and then enter a biscuit firing kiln, biscuit firing is carried out under the temperature ranging from 1080 to 1160 DEG C, heat preservation is carried out in an area with the temperature ranging from 1040 to 1060 DEG C, the sintering time of the area is prolonged, and the sintering process for oxidizing atmosphere can be enhanced at the same time so as to obtain the ceramic tile blank bodies.

Description

Technical field:

[0001] The invention relates to a formula and a method for manufacturing ceramic tile bodies and glazed tiles by using polishing waste slag. Background technique:

[0002] The output of China's building and sanitary ceramics has ranked first in the world for 18 consecutive years. However, with the rapid development of the ceramic industry, ceramic industry waste is increasing, especially ceramic polishing waste. According to incomplete statistics, only the Foshan ceramic production area produces more than 3 million tons of ceramic polishing slag every year, while the national ceramic polishing slag is estimated to be more than 10 million tons per year. Such a large amount of ceramic polishing waste is no longer a problem that can be solved by simple landfill, and with the development of economy and social progress, environmental protection has become the focus of people's attention. The accumulation of ceramic polishing waste occupies land and affects the lo...

Embodiment Construction

[0040] The present invention is described in further detail below in conjunction with embodiment.

[0041] The present invention relates to a kind of preparation method of using ceramic polishing waste slag to produce glazed tile, which comprises the following steps:

[0042] A. Preparation of green bodies with good high-temperature bonding properties

[0043] The composition of the green body is shown in the following table 2:

[0044] Table 2 Components of green body (parts by weight)

[0045]

[0046] The above-mentioned raw materials are batched according to weight, and an appropriate amount of water is added into a ball mill for ball milling, and ground into a slurry whose fineness, sieve residue, and moisture content meet the parameters in Table 1 below. The moisture content of the material (adjust the moisture content according to the size of the product and the dry and wet weather), and the particle gradation of the powder are the requirements in Table 1 below.
