Problems solved by technology

The analysis shows that in the production of ceramic balls, the drying shrinkage is uneven inside and outside, not synchronized, and the stress difference caused by the uneven firing shrinkage inside and outside is the main reason for the fine delamination phenomenon, which reduces the performance of the ceramic balls, so it is difficult to achieve export porcelain. The standard of the ball

Abstract

The invention discloses a method for enhancing the strength of an industrial porcelain ball. The industrial porcelain ball comprises a seed material, a masterbatch and a surface material; the seed material comprises the following raw materials by weight percentage: 40-72% of Wangxian stone, 15-33% of Yichun raw material, 10-20% of Chenzhou mud and 5-15% of Yichun washing mud; the masterbatch comprises the following raw materials by weight percentage: 50-60% of Wangxian stone, 12-25% of Yichun raw material, 15-25% of Chenzhou mud, 5-15% of Yichun washing mud and 1-8% of bowl porcelain powder; the surface material comprises the following raw materials by weight percentage: 35-70% of Wangxian stone, 15-35% of Yichun raw material, 10-20% of half-mountain mud and 5-15% of black mud. The industrial porcelain ball prepared through the method provided by the invention is unlikely to be peeled and delaminated, has higher compressive strength, has a low breakage rate in drop tests, and can meet the export standards and requirements.

Description

technical field [0001] The invention relates to the technical field of manufacturing industrial ceramic balls, in particular to a method for enhancing the strength of industrial ceramic balls. Background technique [0002] In the petrochemical industry, high-, medium-, and low-aluminum filler ceramic balls are often used, while abrasive ceramic balls are generally high-alumina ceramic balls. In the process of ceramic ball processing, generally after the raw materials are processed, there are three production methods: wet molding, dry molding, and enamelling. Wet molding requires too much labor, and the output is small, so it is gradually eliminated, and the production of φ3mm-φ30mm: such as the problem of mold and press output, is basically replaced by dry powder enamel. [0003] With the increasing export volume, there is a big difference between domestic and foreign requirements. The original industrial ceramic ball industry standard: HG / T3683.1-2014 (Table) records the c...
