A kind of dry granule glaze, dry granule glaze slurry and dry granule glaze porcelain brick

Abstract

The invention belongs to the field of ceramics and discloses a dry glaze, a dry glaze slurry and a dry glaze porcelain tile. The dry glaze is composed of frit and raw material with a mass ratio of (10-30):100, wherein the chemical composition of the frit is Al 2 o 3 , SiO 2 , CaO, K 2 O, BaO, ZnO, MgO, Na 2 O composition; the chemical composition of the raw meal is Al 2 o 3 , SiO 2 , CaO, K 2 O, BaO, ZnO, MgO, Na 2 O and SO 2 . The dry glaze can be directly made into glaze slurry for application, which is beneficial to simplify the process requirements and reduce the difficulty of production; the firing time is 50-60 minutes, and the firing temperature is low. Lower, lower energy consumption; more stable formula, adapt to different process conditions and kiln temperature. Compared with ordinary dry granule glaze porcelain tiles or ceramic tiles with dry granule effect, it simplifies the production requirements, reduces the production cost, breaks the complicated process of dry granule + glue / suspending agent, and combines the production process of dry granule glaze with full polishing The process of glaze is synchronized.

Description

technical field [0001] The invention belongs to the field of ceramics, and in particular relates to a dry glaze, a dry glaze slurry and a dry glaze porcelain tile. Background technique [0002] Compared with ordinary full-polished glaze, the glaze surface of dry-granulated glaze is more transparent, which is more suitable for the production of dark products, and the glaze amount of dry-granulated glaze is more than that of ordinary full-polished glaze, so that the polished dry-granulated glaze Glazed ceramic tiles have a smoother glaze surface and smaller water ripples, which is conducive to improving the texture of the glazed surface after polishing, and is more conducive to obtaining high-end ceramic tiles. In the field of bright surface products such as anchor rock slabs and ceramic slabs, dry glaze is more widely used. [0003] At present, the production process of ordinary dry-grain glazed porcelain tiles or tiles with dry-grain effect is to mix pre-made frit particles...

AI Technical Summary

Problems solved by technology

The dry granules of this product stick to the glaze surface through the bonding effect of glue, suspending agent, etc., but this method is limited by the type of additives such as glue and suspending agent, and it is prone to uneven distribution of dry granules , The fluidity of the glaze slurry becomes poor, the dry particles are not firmly bonded, and the glaze slurry is prone to bubbles, etc.

When entering the kiln, the dry particles bonded on the brick surface will be more or less sucked away by the kiln, resulting in lack of glaze and dry particles.

The dry particles that are sucked into the kiln will adhere to the roller table to increase the risk of rod nails, adhere to the top of the kiln, and fall during the production of other products, causing product defects

In addition, some suspending agents also affect the color of dry granules, which greatly affects the performance of the surface of dry granulated glazed porcelain tiles, the overall aesthetics and the excellent rate of tile products, and the application of dry granules increases the cost.

[0004] The existing dry glaze needs to be applied with the help of binders, etc., which increases the difficulty of the process and makes it more difficult to obtain high-quality products, which also leads to high production costs of dry glaze porcelain tiles
