Abstract
The present invention provides a method for preparing high-strength, high-whiteness, high-thermal-shock-resistance petuntse. The preparation method comprises the following production steps of (1) mechanically beating pyrophyllite, washing to remove mud and removing iron by magnetic separator and sieving; (2) mechanically beating kaolin, washing to remove mud and removing iron by magnetic separator and sieving; (3) according to the percentage by weight, weighting 28% of potassium feldspar, 12% of aluminum oxide, 10% of illite, 10% of montmorillonite and 30% of kaolin, mixing with 10% of pyrophyllite, ball milling, removing iron by magnetic separator and sieving to obtain petuntse materials; (4) press filtering the above sieved petuntse materials to obtain petuntse. The petuntse prepared by the invention is suitable for the production of ceramic products for daily use, product qualification rate is high. The strength, whiteness and thermal shock resistance of the product are superior to that of bone china, porcelain and highly siliceous magnesia porcelain, production cost is low, products are particularly applied in dishwashers, microwaves, refrigerators and sterilized cupboard.
Description
Technical field
The present invention relates to ceramic field, specifically a kind of preparation method of high-strength, Gao Bai, high-heat resistance shock resistant porcelain mud.
Background technology
In the composition of raw materials of household porcelain production, have bone china mud, magnesia porcelain mud, the multiple formulations such as high silicon porcelain mud, made product respectively has merits and demerits.Normally transparence is better for bone ash matter, magnesia, high siliceous household china, and impact strength and heat-shock resistance are obviously not enough, and production cost is higher.In domestic ceramics industry, often this series products is called " good-looking be not durable ".
Domestic ceramics in use, comprises in the cleaning after use, often collides, and easily occurs touching scarce; When thermal sterilization to tableware of food-steaming and disinfection cupboard, the poor tableware of part heat-shock resistance then can break because cold and hot contraction causes.
How to produce the domestic ceramics that high strength, high-heat resistance shock resistant and whiteness are higher, suitably reduce production cost, tableware simultaneous adaptation is used on dishwasher, is the problem studied in domestic ceramics industry and tackling key problems simultaneously.
Summary of the invention
For solving the deficiency in above-mentioned domestic ceramics performance, the invention provides a kind of preparation method of high-strength, Gao Bai, high-heat resistance shock resistant porcelain mud.
The preparation method of high-strength, Gao Bai, high-heat resistance shock resistant porcelain mud of the present invention, comprises following production stage:
(1). get agalmatolite machinery and beat 15 ~ 16 hours, after washing mud and magnetic separator deironing, cross 325 mesh sieves with for subsequent use;
(2). get kaolin machinery and beat 15 ~ 16 hours, after washing mud and magnetic separator deironing, cross 325 mesh sieves with for subsequent use;
(3). get by weight percentage potassium felspar sand 28%, aluminum oxide 12%, illite 10%, montmorillonite 10%, above-mentioned kaolin 30% for subsequent use, above-mentioned agalmatolite for subsequent use 10% mixed after carry out ball milling 25 ~ 26 hours, then through magnetic separator deironing, cross 325 mesh sieves and obtain pug;
(4). the pug after above-mentioned sieving is carried out press filt, i.e. obtained high-strength, Gao Bai, high-heat resistance shock resistant porcelain mud.
It is beat kaolin and pyrophyllite with machinery that described machinery is beaten, and its grain pattern is changed.
Described mud of washing the kaolin beaten through machinery and pyrophyllite is put into water stir, and utilizes the difference of gravity, make the normal process steps of selected raw material in coarse particles and foreign material sepn process.
Described deironing is the normal process steps utilizing magnetic separator to be sorted out from raw material by ferromagnetic material.
Described press filt is the normal process steps adopting pressure filter to make slurry dewatering.
The present invention adds aluminum oxide in porcelain mud, makes the aluminium content in porcelain mud bring up to about 36%, and the intensity of ceramic is improved, and the resistance to impact shock of ceramic is not less than 1.5J/cm
2.Pyrophyllite and illite is added in porcelain mud, firing range can be increased, reduce the ceramic cracking because thermal shocking causes or distortion, improve the heat-shock resistance of ceramic, make the heat-shock resistance of ceramic reach heat exchange in 220 DEG C of inputs, 20 DEG C of water and once do not split.
Add relatively large potassium felspar sand in porcelain mud of the present invention, the carcass densification of ceramic can be made, all have effect to the intensity of goods, whiteness and heat-shock resistance are stable.Adding montmorillonite in porcelain mud, is utilize the features such as montmorillonite particle is small, improves the plasticity of pug, is conducive to the shaping of ceramic body.
The present invention carries out machinery to kaolin and pyrophyllite, and to beat and wash mud be make raw material mix be partial to diamond shaped and refinement, can improve the plasticity of pug, overcomes porcelain mud because of the ceramic body caused by aluminum content height and be easy to the problem that ftractures in shaping.
The present invention adopts magnetic separator to carry out deironing process to raw material, is the iron level in porcelain mud is reduced, and reduces the colour developing of irony in ceramic, improves the whiteness of ceramic, makes the whiteness of ceramic reach more than 80.
High-strength, Gao Bai, high-heat resistance shock resistant porcelain mud prepared by the present invention, be applicable to the production of ceramic ware for daily use, conforming product rate is high, the intensity of product, whiteness and heat-shock resistance are better than bone china, magnesia porcelain and the siliceous porcelain of height, production cost is low, and product is specially adapted to use in dishwasher, microwave oven, refrigerator, disinfection cupboard.
Embodiment
The present invention will be described in detail by the following examples.
Embodiment: (1). get agalmatolite machinery and beat 16 hours, after washing mud and magnetic separator deironing, cross 325 mesh sieves with for subsequent use;
