Abstract
The invention relates to the technical field of ceramic production and discloses high-hardness domestic ceramic and a production method thereof, wherein the high-hardness domestic ceramic comprises a blank body and a glaze layer, and the blank body comprises: kaolin, alumina, zirconia, bentonite, waste ceramic slag, quartz and feldspar, wherein the glaze layer comprises: kaolin, magnetic powder, talcum powder, spodumene, lithium porcelain stone, quartz and calcite; the invention also provides a production method of the high-hardness domestic ceramic, which comprises the following steps: s1: preparing materials; s2: mixing and ball milling. The invention can improve the hardness of the blank after the formula is integrated, the mud cake after refining has uniform tissue and stronger plasticity, improves the hardness of the finished product, can prevent the burnt product from generating black spots, and fills inert gas to improve the stability and prevent the burnt product from generating cracks.
Description
Technical Field
The invention relates to the technical field of ceramic production, in particular to high-hardness domestic ceramic and a production process thereof.
Background
Due to the continuous development of ceramic science and technology. And the market demand for new ceramic products is increasing day by day, so that ceramic enterprises are forced to develop new products continuously, and the problems and the influence of the factors of product change on the reasonable organization of the production process cannot be considered. In order to enhance adaptability, ceramic enterprises not only need to greatly improve the scientific and technical application level and the research capability of new products and continuously update the products, but also need to adopt advanced production organization methods such as a plan review method, a grouping process, multi-variety mixed flow production and the like.
The domestic ceramic product is inevitably extruded, collided, scratched or abraded in the normal use process, and is easily damaged or scratches, cracks or gaps are left on the product due to insufficient hardness to cause flaws, so that the attractiveness of the ceramic product is influenced, even the domestic ceramic product is used, and the requirements of people cannot be met.
Disclosure of Invention
Technical problem to be solved
Aiming at the defects of the prior art, the invention provides high-hardness domestic ceramic and a production process thereof, and mainly aims to solve the problems that the ceramic produced by the prior process is not enough in hardness, is easy to damage or leaves scratches, cracks or gaps on a product to cause flaws, and influences the attractiveness and even the use of the ceramic product.
(II) technical scheme
In order to achieve the purpose, the invention provides the following technical scheme:
the high-hardness domestic ceramic comprises a blank body and a glaze layer, wherein the blank body comprises the following components in parts by mass: 20-100 parts of kaolin, 30-50 parts of alumina, 10-18 parts of zirconia, 12-18 parts of bentonite, 15-24 parts of waste porcelain slag, 15-30 parts of quartz and 20-50 parts of feldspar, wherein the glaze layer comprises the following components in parts by mass: 15-80 parts of kaolin, 6-12 parts of magnetic powder, 12-16 parts of talcum powder, 10-15 parts of spodumene, 6-12 parts of laponite, 10-15 parts of quartz and 7-20 parts of calcite.
A production method of high-hardness domestic ceramic comprises the following steps:
s1: preparing materials, namely taking the raw materials according to the weight part for later use;
s2: mixing and ball milling, namely mixing the raw materials of the blank, then grinding by adopting a ball mill, and adding water during ball milling;
s3: screening and removing impurities, wherein after ball milling, a sieve with 150 meshes and 250 meshes is used for screening to remove coarse particles and tail sand;
s4: performing filter pressing refining, namely performing filter pressing on the screened slurry by using a filter press to extrude water, and then refining by using a refiner;
s5: molding, namely placing the refined pug into an extrusion model, and extruding a blank body in a required shape under the action of a hydraulic press;
s6: glazing, namely glazing the blank body by a glaze spraying process;
s7: and (4) sintering, namely sintering the glazed green body.
Further, when ball milling is performed in S2, 0.2 to 0.8 of the total raw materials are first added for ball milling, and after ball milling is performed for 3 to 9 hours, the remaining raw materials are then added for ball milling for 3 to 10 hours, and during ball milling, the raw materials of the blank are: ball: the weight ratio of water is 1: (1.2-1.6): (0.6-1.8).
On the basis of the scheme, in the step S3, after screening, a wet magnetic separator is used for removing iron impurities, the screening and iron removal processes are carried out for 2-4 times, after iron removal, the inspection work is carried out, the next process is carried out when the inspection is qualified, and unqualified iron removal is carried out continuously.
As a further proposal of the invention, the mud segment is placed in an environment with normal temperature and humidity for 3 to 7 days after the refining in the S4.
