Pretreatment device for water absorption detection sample of ceramic tile and control method of pretreatment device

Abstract

The invention relates to a pretreatment device for a water absorption detection sample of a ceramic tile and a control method of the pretreatment device. The pretreatment device comprises a rack, a conveying mechanism, a positioning mechanism, a plurality of groups of milling mechanisms and a control system; the rack is composed of a pair of longitudinal beams and a cross beam fixedly arranged at the tops of the longitudinal beams, the positioning mechanism is arranged at the bottom of the cross beam of the rack and used for fastening ceramic tiles on the conveying mechanism to prevent the ceramic tiles from unnecessarily moving in the milling process, the groups of milling mechanisms are arranged at the top of the positioning mechanism, the milling mechanisms are used for milling the surfaces of the ceramic tiles, the conveying mechanism is arranged at the bottom of the positioning mechanism, the conveying mechanism is used for conveying the to-be-treated ceramic tiles in place and providing continuous translation driving force in the milling process, and the control system is used for controlling the pretreatment device.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a pretreatment device and a control method for testing samples of water absorption of ceramic tiles. Background technique [0002] Water absorption refers to the ratio of the amount of water absorbed by the voids in the ceramic tiles to the mass of the ceramic tiles. It is one of the important indicators for judging the quality of ceramic tiles. It indirectly reflects the size of the internal voids and the density of the structure of the ceramic tiles. The greater the water absorption , indicating that the larger the internal void, the looser the structure, the lower the strength of the ceramic tile, on the contrary, the smaller the internal void, the denser the structure, the higher the strength of the ceramic tile. [0003] According to the national standard (GB / T3810.3-2006) "Ceramic Tiles Test Method Part 3: Determination of Water Absorption, Apparent Porosity, A...

Problems solved by technology

However, in actual production, it is found that the water absorption rate of the enamel part of the glazed ceramic tile after sintering is different from that of the green body part. Affected by the degree of sintering, the water absorption rate of the green body layer in different depth directions is also different.

Use the ceramic brick sample without surface milling treatment to test the water absorption rate, the test result is easily affected by the enamel part, and has poor correlation with the sintering degree in the middle of the green body; when the kiln firing temperature, firing curve and other working conditions After disorder, the detection of water absorption cannot directly reflect the fluctuation of process parameters and the change of finished product quality
