A kind of preparation method of porcelain clay

Abstract

The invention discloses a making method of petuntse. The making method is characterized by including following steps: material selecting, soil blending, opposite smashing, material flushing, water washing, sieving, deironing, precipitating, corroding and hydraulic press-drying. Compared with the prior art, the making method has the advantages that raw materials are smashed by means of opposite smashing, so that plasticity and viscosity of the raw materials are guaranteed; the raw materials are flushed at a position where opposite smashing is performed, so that the raw materials can be flushed fully, waste of the raw materials is reduced, and labor intensity and time are reduced; due to the precipitating step, press-drying time is greatly shortened; tiny plant particles that are not sieved away in the sieving process can be corroded through corroding, so that performance of petuntse is improved. Petuntse processed by the method is higher than pug obtained by milling of a ball mill in plasticity and viscosity, has moderate fluidity, has the advantages of better plasticity and viscosity and moderate fluidity when compared with a single raw ore material and less in cracking and deforming in the firing process.

Description

technical field [0001] The invention relates to the technical field of production and processing of porcelain clay, in particular to a preparation method of porcelain clay. Background technique [0002] Porcelain clay is a raw material for making porcelain, and the quality of porcelain clay directly affects the quality of porcelain. The main raw material of porcelain clay in the prior art is kaolin, which is a non-metallic mineral. Clay and clay rock mainly composed of stone group clay minerals, kaolin is white and fine, soft and soft soil, has good physical and chemical properties such as plasticity and fire resistance, and its mineral composition is mainly composed of kaolinite, halloysite, hydromica, illite , montmorillonite, quartz, feldspar and other minerals. The main production process is as follows: After selecting the materials, use a ball mill to crush the raw materials, then hydrate the slurry with water and remove impurities. After removing impurities, use a mud...

AI Technical Summary

Problems solved by technology

The main production process is as follows: After selecting the materials, use a ball mill to crush the raw materials, then hydrate the slurry with water and remove impurities. After removing impurities, use a mud filter press to press the mud into mud cakes to complete the production of porcelain mud. The viscosity of the raw material is not good, and it takes a long time to press the mud directly into a mud cake with a machine after removing impurities. The porcelain clay produced in this way is not good in plasticity and viscosity, and the porcelain is easy to crack and deform during the firing process.
