Description

Waste porcelain powder recycling method
Technical Field
The invention relates to a ceramic waste treatment method, in particular to a method for recycling waste ceramic powder.
Background
In the ceramic production process, unqualified products inevitably appear, and if the unqualified products are treated as solid wastes, the treatment difficulty is high, and the production cost is greatly increased, so that the waste porcelain is imperative to be recycled after being crushed. The chemical composition of the common waste porcelain powder comprises SiO2, Al2O3, K2O and Na2O, wherein the content of Al2O3 is close to that of feldspar, and the content of K2O and Na2O are lower than that of the feldspar, so that the waste porcelain powder can be partially replaced in a slurry formula under the general condition.
Based on this, in the prior art, the waste porcelain powder can only be used to 10% by using a high-pressure grouting method, but because the conventional firing method has high requirement on the plasticity of the raw material, the common practice of the same industry under the production mode of conventional firing is to add about 4% of the waste porcelain powder into the slurry. The waste ceramic powder belongs to a calcined material, and the excessive addition of the waste ceramic powder can cause the performance change of slurry and ceramic, and the increase of the proportion can cause the deviation of hard indexes such as water absorption and the like. Therefore, how to increase the use amount of the waste porcelain powder in the slurry by using a conventional firing production mode under the condition of ensuring that the performances of the slurry and the porcelain are not changed is a technical problem to be solved at present.
Disclosure of Invention
The invention aims to solve the technical problems and provides a method for recycling waste porcelain powder, wherein the addition amount of the waste porcelain powder is increased to about 9% by adjusting the proportion of other raw materials in a formula.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a method for recycling waste porcelain powder comprises the following steps:
(1) crushing waste porcelain, wherein the particle diameter is not more than 5 mm;
(2) preparing slurry, wherein a slurry dry material comprises the following components: 8% of quartz sand, 11% of mud feldspar, 23% of kaolin, 10% of pyrophyllite, 13% of sericite, 18% of illite clay, 8% of black mud and 9% of waste porcelain powder; ball milling for 3-5 hr, sieving with 350 mesh sieve to obtain slurry with sieved residue less than 6.0%, and making into slurry for ceramic production.
Compared with the prior art, the invention adopting the technical scheme has the beneficial effects that:
the addition of the waste porcelain powder can be improved to 9% by reasonably adjusting the proportion of other raw materials in the slurry formula, and the slurry can ensure that the water absorption of a finished product meets the national standard, the properties of the slurry and finished porcelain cannot be changed, and the product quality is ensured; the utilization of the waste porcelain powder of the invention is far beyond the current level in the same industry, and the waste porcelain powder can be completely recycled, thereby reducing the production cost and the waste treatment cost and improving the economic benefit and the social benefit.
Detailed Description
The present invention will be described in detail with reference to examples.
The method for recycling waste porcelain powder comprises the following steps:
(1) the method comprises the steps of crushing defective products (waste porcelain) produced in the ceramic production process, grinding the defective products (waste porcelain) for 3-5 hours by adopting a wet ball milling method, sieving the crushed defective products with a 350-mesh sieve until the residue is less than 6.0 percent, and preparing the waste porcelain powder.
(2) And (3) doping the waste ceramic powder into the production slurry to carry out ceramic production, wherein the doping amount of the waste ceramic powder is 9% of the mass of the production slurry.
The production slurry doped with the waste porcelain powder comprises the following components in percentage by weight: 8% of quartz sand, 11% of mud feldspar, 23% of kaolin, 10% of pyrophyllite, 13% of sericite, 18% of illite clay, 8% of black mud and 9% of waste porcelain powder.
(3) And producing the ceramic product doped with the waste ceramic powder slurry according to a conventional firing mode.
In the embodiment, the main physical properties of the slurry produced by adding the waste porcelain powder are as follows: specific gravity: 1.774-1.800, V0: 28-56', drying shrinkage: 3.0-3.6%, full shrinkage: 11.5-12.5%, firing bending: 25-36 mm, and the water absorption rate is less than 0.5%;
the slurry formula for producing the ceramic powder without adding the waste ceramic powder generally comprises the following components: 10% of quartz sand, 14% of mud feldspar, 26% of kaolin, 10% of pyrophyllite, 14% of sericite, 18% of illite clay and 8% of black mud.
The mud blank prepared by doping the waste porcelain powder comprises the following chemical components after being dried: SiO22 64.59%，Al2O323.67%，CaO 0.58%，MgO 0.56%，Fe2O3 1.25%，TiO2 0.33%，K2O 2.21%，Na2O 1.69%，IL 5.12%。
The dried mud blank prepared from the ceramic slurry for original production comprises the following chemical components: SiO22 64.68%，Al2O3 23.56%，CaO 0.52%，MgO 0.57%，Fe2O3 1.31%，TiO2 0.30%，K2O 2.35%，Na2O 1.55%，IL 5.16%。
The mixing amount of the waste porcelain powder is based on that the waste porcelain powder belongs to barren raw materials, and can replace part of barren raw materials such as quartz sand, feldspar and kaolin with low plasticity according to chemical components. In the present example, 9% of waste porcelain powder was used in place of 2% of quartz sand, 3% of mud feldspar, 3% of kaolin and 1% of sericite. The addition amount of the waste porcelain powder is controlled to be 9 percent, the plasticity of the produced slurry is not influenced, and the chemical components of the produced slurry can be ensured.
Compared with the original slurry, the slurry production method has the advantages that the slurry dividing data and the performance of the slurry produced after the waste ceramic powder is added are basically unchanged. Through a product trial production test, the production slurry doped with the waste porcelain powder has the advantages of drying, sintering shrinkage consistent with that of the original production slurry, less mud blank defects and capability of being replaced.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the scope of the present invention, which is defined by the appended claims.
