Definitions

  • This invention is a method for the production of glazed ceramic tiles with brilliance and high resistance to mechanical and chemical attacks. This process in the field of:
  • C04B41/52 Multiple coating or impregnating multiple coating or impregnating with the same composition or with compositions only differing in the concentration of the constituents, is classified as single coating or impregnation.
  • C03C8/14 Glass frit mixtures having non-frit additions, e.g. opacifiers, colorants, mill- additions.
  • Tile is a piece of synthetic ceramic with a few millimeters thickness and various lengths and widths. On one side it has a glossy surface and is completely smooth and polished. Tiles are pottery and ceramic products having special applications and importance in constructions, such as bathrooms, toilets, kitchens and public toilets, etc. Tiles are used for interior and exterior decoration as well as sanitation and moisture insulation purposes. Furthermore, materials, usually solid, mostly made up of non-metallic and inorganic contents are called ceramics. Moreover, according to some definitions, materials chemically composed of a mixture of clay, sand and feldspar made into semi-glass pieces at high temperatures are called ceramics which are almost inflammable, insoluble and very hard. Tile preparation steps:
  • the first step is selection and preparation of raw materials.
  • Raw materials are clays
  • Slurry preparation means mixing the supplied materials with water to
  • Forming The slurry is Pumped into spay dryer system for making ceramic granules with desired shapes and sizes in next step granules transfer to the mold in the pressing machine to form ceramic body with desired sizes and thickness.
  • Glazing on tile after drying the biscuits for decoration and create a glassy layer on the surface of the tiles glazes are applied with very different formulations depend on type of production. Applying the glaze can be carry out with some equipment’s such as vela, bell tray, spray or disc.
  • Tiles are fired in kilns. Temperatures and times for firing are depend on type of the production. A piece of tile consists of two parts:
  • the main part of a ceramic tile is its body.
  • the glaze on the tile which is a glassy material forming the outer part.
  • the glazes include a wide range of Inorganic and mineral compositions. Ceramic glaze is usually a glass-like mixture composed of quartz, feldspar and other materials. These ingredients are then ground, powdered and made into a Slurry with water. The ceramic object is then formed with pressing and after glazing and decorating heated in the kiln to a certain temperature after drying. After glazing and firing the tiles, desired writings and designs can be applied with process named third firing and heated again. In this way, the writing and design on it becomes more durable.
  • Producing composite glaze ceramic tiles is a technique process of producing for producing ceramic tiles with effects by making composite glazes which have high resistance to chemical and mechanical attacks.
  • Current production processes have disadvantages such as impermanency of the effects on the tile surface, lack of resistance to mechanical and chemical destructive factors, inappropriateness for use in crowded places and outdoor environments, need for engobe and additional glaze or any complementary activities to achieve the desired effect in the production line, need for decoration through third firing, very high cost compared to common tiles,
  • the glaze is applied as a single layer on the tile biscuit without the need for engobe and separate glaze or any additional operations to carry out the desired effect in the glazing line.
  • the firing is also carried out once without requiring decoration by the third firing, making it very economical in terms of engobe and glaze consumption and time for production.
  • Engobe A white or colored clay slip coating applied to a ceramic body to give it decorative color or improved texture and regulate flatness of the tiles.
  • first, engobe and then glaze should be applied on the tile’s dried biscuit, and then glittering particles or effects are sprayed or created via dry application once, or a few supplementary times, on the surface of the glazed tile. While in the method claimed here, it is applied as a single-layer glaze on the tile’s biscuit without the need for engobe or separate glaze and any additional operations to create the desired effect on the glaze line and fired also in one session (without the need for decoration for third firing) and therefore, quite economical in terms of application and consumption of engobe and glaze.
  • the particles in the glaze can affect all the parameters effective in production such as melting temperature, thermal expansion coefficient, surface tension, etc. and help adjust them due to their dispersion on the surface and depth of the glaze and existence of composite structure. Ceramic tiles can be produced in both unpolished and polished types. The use of polish can result in greater surface brightness and smoothness.
  • the desired glaze includes a base comprised of an engobe, a special matt glaze and mica and aluminum particles as effects.
  • the special brilliant glaze formulation used in the base glaze is applied depending on the type of tile for the part specified in Table 1 .
  • additives will be charged into the ball mill depending on the metre of production and production conditions (Table 2).
  • the ball mill is started and the output shall be the same as the conditions mentioned in Table 3.
  • the last step of glaze preparation is adding metal and ceramic particles to the glaze in the mixer (Table 4). After adjusting the glaze conditions for application in the production line, first the appropriate weight of the applied glaze must be obtained for having proper tile coverage and flatness.
  • the chamfering process is done to make the sides of the tiles square and more accurately sized, which can be carried out in wet or dry states, depending on the type of tile. If the manufactured tile is unpolished type, it is transferred to the sorting line and prepared for delivery after packaging. In case the tiles manufactured require polishing, they enter the polish line for complete polishing and application of Nano materials. They are then transferred to the sorting and packaging lines.

Abstract

La production de carreaux de céramique à glaçure composite est une technique de production de carreaux de céramique avec des effets en fabriquant des glaçures composites qui ont une résistance élevée à des attaques chimiques et mécaniques. La présente invention concerne un nouveau procédé, la glaçure étant appliquée sous la forme d'une seule couche sur le biscuit de carreau sans nécessiter d'engobe et de glaçure séparée ni aucune autre opération supplémentaire pour obtenir l'effet souhaité dans la ligne de glaçure. La cuisson est également effectuée une fois sans nécessiter l'application de décoration avec une troisième cuisson, ce qui rend le procédé très économique en termes de consommation d'engobe et de glaçure et de temps de production.
