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 the preparation method of a kind of high-strength, Gao Bai, high-heat resistance shock resistant porcelain mud.
Background technology
In the composition of raw materials of household porcelain production, there are bone china mud, magnesia porcelain mud, the multiple formulations such as high silicon porcelain mud, made product respectively has merits and demerits.Bone ash matter, normally transparence is better for 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 not being durable ".
Domestic ceramics in use, comprises in the cleaning after use, often bumps, and easily occurs touching scarce; At food-steaming and disinfection cupboard, during to the thermal sterilization of tableware, the poor tableware of part heat-shock resistance 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 costs, tableware simultaneous adaptation is used on dishwasher, be the problem of studying and tackling key problems in domestic ceramics industry simultaneously.
Summary of the invention
For solving the deficiency in above-mentioned domestic ceramics performance, the invention provides the preparation method of a kind of high-strength, Gao Bai, high-heat resistance shock resistant porcelain mud.
The preparation method of high-strength, Gao Bai of the present invention, high-heat resistance shock resistant porcelain mud, 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%, montomorillonite 10%, above-mentioned kaolin 30% for subsequent use, above-mentioned agalmatolite 10% for subsequent use and carry out ball milling 25～26 hours after mixed, then through magnetic separator deironing, cross 325 mesh sieves and obtain pug;
(4). the pug after above-mentioned sieving is carried out to press filt, make high-strength, Gao Bai, high-heat resistance shock resistant porcelain mud.
It is with machinery, kaolin and pyrophyllite to be beaten that described machinery is beaten, and its grain pattern is changed.
The described mud of washing is the kaolin of beating through machinery and pyrophyllite to be put into water stir, and utilizes the difference of gravity, makes the conventional operation of selected raw material in coarse particles and foreign material sepn process.
Described deironing is the conventional operation of utilizing magnetic separator that ferromagnetic material is sorted out from raw material.
Described press filt is to adopt pressure filter to make the conventional operation of slurry dewatering.
The present invention adds aluminum oxide in porcelain mud, makes the aluminium content in porcelain mud bring up to 36% left and right, and the intensity of ceramic is improved, and the resistance to impact shock of ceramic is not less than 1.5J/cm
2.In porcelain mud, add pyrophyllite and illite, can increase firing range, reduce the ceramic cracking or the distortion that cause due to thermal shocking, improve the heat-shock resistance of ceramic, make the heat-shock resistance of ceramic reach 220 DEG C and drop into heat exchange in 20 DEG C of water and once do not split.
In porcelain mud of the present invention, add relatively large potassium felspar sand, can make the carcass densification of ceramic, intensity, whiteness and the heat-shock resistance to goods stablized all effect.In porcelain mud, adding montomorillonite, is to utilize the features such as montomorillonite particle is small, improves the plasticity of pug, is conducive to the moulding of ceramic body.
The present invention carries out machinery to kaolin and pyrophyllite, and to beat and wash mud be to make raw material mix be partial to diamond shaped and refinement, can improve the plasticity of pug, overcomes porcelain mud and in moulding, be easy to the problem of cracking because of the high caused ceramic body of aluminum content.
The present invention adopts magnetic separator to carry out deironing processing 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, and the whiteness of ceramic is reached more than 80.
That prepared by the present invention is high-strength, Gao Bai, high-heat resistance shock resistant porcelain mud, be applicable to the production of ceramic ware for daily use, conforming product rate is high, intensity, whiteness and the heat-shock resistance of product is better than bone china, magnesia porcelain and high siliceous porcelain, 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;
