Porcelain ceramic particle water scalpel sand and preparation method thereof

Abstract

The invention relates to porcelain ceramic particle water scalpel sand and a preparation method thereof. A porcelain ceramic tile consists of the following components including, by weight,65%-75% of SiO2, 15%-25% of Al2O3, 1.0%-2.0% of FeO3, 0.5%-1.0% of CaO, 1%-2% of MgO, 1%-4% of K2O and 2%-4% of Na2O. The preparation method for the porcelain ceramic particle water scalpel sand comprises the following steps of(1) preparing, wherein after pug, sand and auxiliary materialadditives are added into a ball mill in proportion to prepare mud, powder is sprayed through a spray drying tower, and the mud is dried and is fed into a roller kiln to be fired; (2) crushing, wherein the porcelain ceramic tile is crushed and processed to obtain porcelain ceramic particles with a proper particle size; (3)grinding, wherein all particles are added into a grinding mill to be coarsely groundand then finely ground; (4) screening, wherein the particles pass through a screen to be separated to obtain porcelain ceramic particles, namely high-pressure water jet cut abrasive water scalpel sand; and (5) dust removal, wherein the porcelain ceramic particle water scalpel sand is subjected to dust removal to obtain porcelain ceramic particle water scalpel sand abrasive which meets requirements.

Description

technical field [0001] The invention relates to the technical field of ceramic tiles, in particular to a porcelain ceramic granular waterjet sand and a preparation method thereof. Background technique [0002] High-pressure water jet cutting is a new type of cold-state manufacturing process that has developed rapidly in recent years. Its working principle is to use a high-pressure pump and a supercharger to pressurize the water flow to 100-400MPa, and use a special cutting nozzle to The speed of 1000m / s sprays water jets to cut ceramics, glass, stone, wood, etc. in order to better cut complex geometric shapes. When people use high-pressure water jet cutting, they often mix water jets into the water jet. Sand is used as a water jet cutting abrasive to achieve the purpose of enhancing cutting ability and processing hard materials through the erosion and grinding of abrasives. [0003] At present, waterjet sand usually uses silica, alumina or garnet with a particle size of 30-...

AI Technical Summary

Problems solved by technology

Although garnet is a good abrasive for water jet cutting, because garnet is a non-renewable mineral, it is not in line with the national environmental resource protection policy to exploit and use it in large quantities. Therefore, in order to reduce the use of raw minerals and reduce the production of enterprises Cost, it is increasingly important to develop a new water jet cutting abrasive with good hardness, wear resistance, and performance in line with waterjet sand
