Such as Chinese patent CN1205148C discloses a kind of " method for utilizing waste porcelain and the porcelain clay thereof that makes thereof ", and its shortcoming of this method is, introduces part waste porcelain in the green body mud material formula, and other is ceramic raw material, like this The crystal phase formation is not perfect during the manufacturing process, the product stability is poor, and defective products are prone to appear
At the same time, the purpose of fully utilizing waste ceramics has not been achieved
low use value

Embodiment 1

[0020] Embodiment 1 Grouting molding

[0021] 1. Weigh raw materials according to parts by weight to prepare the composition of the following components: waste porcelain powder 90, quartz 2, kaolin 1, clay 4, binder 2.625, water reducing agent 0.375.

[0022] 2. Put the above-mentioned materials into a ball mill and add water to grind, material: ball: the weight ratio of water is 1:1.5:2, carry out wet ball milling to particle fineness 0.15-0.3g / 500ml, obtain thin mud; Ball system in this step It must be the ball in the ball mill.

[0023] 3. Remove the iron from the thin mud with an electromagnetic magnetic separator, and pass it through a three-layer screen of 180 mesh, 200 mesh, and 200 mesh to obtain mud.

[0024] 4. Send the mud stale for 3-7 days to the forming body to make semi-finished products with a moisture content of <2%.

[0025] 5. The semi-finished product is glazed and dried according to the conventional production method, put into the kiln, and fired at a fi...

Embodiment 2

[0028] Embodiment 2 roll forming

[0029] 1. Weigh the raw materials according to the parts by weight to prepare the composition of the following components: waste porcelain 83, feldspar 2, kaolin 10, clay 4, binder 1.

[0030] 2. Put the above materials into the ball mill, the weight ratio of material: ball: water is 1:1.5:1.7. Carry out wet ball milling, the particle fineness is 0.15-0.3g / 500ml, and obtain thin mud; the ball is the ball in the ball mill.

[0031] 3. Remove iron from the thin mud with an electromagnetic magnetic separator, and pass it through a three-layer screen of 180 mesh, 200 mesh, and 200 mesh to obtain mud;

[0032] 4. After the mud is filtered, the mud is vacuum-drained for the first time, stale for 3-7 days, and the mud is vacuum-drained for the second time. The mud section quality standard has a moisture content of 23% and a vacuum degree up to standard.

[0033] 5. Send the mud section to the forming body to make a semi-finished product with a mo...

Abstract

The invention relates to a method for producing a recrystallized ceramic product by utilizing waste ceramic. The method comprises the following steps: selecting and washing the waste ceramic products; breaking the washed waste ceramic products to obtain waste ceramic powder with a particle size less than 6mm; reserving powdered quartz, feldspar, washed kaolin and clay; preparing the materials of the recrystallized ceramic product in parts by weight: 50 to 97 parts of waste ceramic powder, 0 to 30 parts of quartz, 0 to 30 parts of feldspar, 3 to 40 parts of clay, 1 to 30 parts of kaolin, 0 to 15 parts of binding agent and 0.2 to 0.4 part of water reducing agent; grinding the materials in a ball mill with water, wherein the weight ratio of the material to a ball to the water is 1: 1.5: 2; carrying out wet ball milling on the materials to obtain a slurry; preparing a green body by adopting the slurry according to a conventional process flow and a conventional forming method, and burning the green body to form ceramic. According to the method, the waste ceramic is used as a main raw material, the material cost is low, and the enterprise benefit is high. The intrinsic quality of the product is stable, the quality is good, the resource and environment are protected, waste is changed into treasure, and the new way is developed for developing the waste ceramic.

Description

technical field [0001] The invention relates to a production method of ceramic products, in particular to a method for producing recrystallized ceramics from waste porcelain. Background technique [0002] At present, according to relevant statistics, my country's ceramic production ranks first in the world, accounting for about 40%-45% of the world's annual total, of which; daily-use porcelain production is 200 million pieces, sanitary porcelain production is 140 million pieces, floor tile production It is 400 million square meters. The raw materials used in ceramic production are silicate minerals. Silicate minerals are disposable resources and are non-renewable resources. This has caused the depletion of high-quality raw materials required for the production of ceramic raw materials. At the same time, The production process of ceramics is complicated and the degree of mechanization is low, and the waste rate is about 10%-25%. Moreover, the abandonment of worn-out ceramic pr...
