Problems solved by technology

[0002] Raw glaze is commonly used in ceramic products, and a uniform transparent or opaque glass layer is formed during the firing process of ceramics, making the surface of ceramic products beautiful and easy to clean. However, the commonly used raw glaze cannot achieve antibacterial function, and antibacterial must be added agent, but on the one hand, it will lead to an increase in cost; on the other hand, if the amount added is too much, it will cause defects on the ceramic glaze; if the amount added is small, the desired antibacterial effect will not be achieved.

Embodiment 1

[0053] Granite-Based Production of Functional Materials II

[0054] After the granite is roughly crushed to a particle size of less than 400mm, it is placed in a self-collision separator for collision separation. The rotating speed of the separator is 28r / min. Add the fine material and water into the wet ball mill equipped with a hydraulic classifier at the discharge port according to the mass ratio of 60:40. During the ball milling process, the power consumption of the ball mill is 320kw / h, and the speed is 20r / min. The mixing flow rate of the material is 90m 3 / h, to obtain materials with a fineness of 50 meshes or finer, the materials with a finer than 50 meshes are firstly subjected to magnetic separation in a flat-plate magnetic separator with a magnetic field strength of 8500 Gauss, and then magnetically separated in a flat-plate magnetic separator with a magnetic field strength of 11000 Gauss Finally, magnetic separation is carried out under a vertical ring pulsating h...

Abstract

The invention relates to antibacterial ceramic raw glaze and a preparation method thereof, and belongs to the technical field of ceramic materials. The raw glaze comprises the following components: afunctional material II, dolomite, quartz, kaolin, zirconite and zinc oxide. When the functional material II is prepared, specific granite porphyry the ore deposit of which is at the east end of the north foot of Yinshan mountain and the south edge of the middle of Inner Mongolia is used as a raw material, firstly, different element crystals can be subjected to wall breaking stripping and separation layer by layer through mutual collision of the granite porphyry and control of collision conditions, then hydraulic classifier parameters are adjusted according to the specific gravity of the different element crystals, and water separation, classification and enrichment are carried out. Through addition of the functional material II, the glaze density and smoothness can be improved, after the produced porcelain is used, oil stains on the porcelain can be cleaned with clean water without a cleaning agent, secondary pollution is avoided, and the rare earth elements can release far infrared rays and negative oxygen ions after being subjected to high-temperature treatment, so that the finally prepared ceramic device has antibacterial, easy-to-clean and fresh-keeping functions.
