摘要

The formulation of the mass ceramics based on resu00ecduo kaolin for coatings and production process of coatings based on resu00ecduo kaolin.The patent of invention relates to the use of the residue from the processing of kaolin (residue from the kaolin) as raw material constituent of the formulation of ceramic mixtures for the manufacture of ceramic coatings in the form of pressed plates, as well as the corresponding proc Esso to manufacture ceramic coatings containing the residue from the kaolin in its composition.The residue from the kaolin plays simultaneously the functions of raw material forming the structure and raw material forming the liquid phase.The compositions of the ceramic body containing the residue from the kaolin are compatible with the processing steps typically employed by manufacturers of ceramic tiles, i.e.They are compatible and suitable for processing according to the following general steps of processing: a 1u00ac stage: MV selection and storage of raw materials; a 2u00ac stage: MV on the dosage of raw materials; a 3u00ac stage: MV grinding of raw materials constituting the the mass ceru00e2m ICA in ball mills for wet; a 4u00ac stage: MV atomization in spray drier "suspension of mass ceru00e2mACIS from the milling; a 5u00ac stage: MV compaction of atomized in the form of mass plates; a 6u00ac stage: MV drying of plates; a 7u00ac stage: MV decoration of the dry plates; and the a 8u00ac stage: MV for sintering. The compacted ceramic plates in continuous furnaces rolls To promote the sintering of the composition containing the residue from the kaolin clay together with the other materialsAnd, therefore, to optimize the physical and chemical properties and aesthetic attributes of the final product, i.e., the ceramic coating of the type porcelain tiles.Therefore, the use of the residue from the kaolin, in accordance with the general steps exemplified, perfectly compatible from the point of view of technical with the technologies currently employed by the industry of ceramic coatings of Brazil and the world.The process object of invention, for use of the residue from the kaolin in formulations of ceramic body and its production, applied in coatings proved entirely satisfactory enabling formulations that meet the characteristics of the coating on the basis of clear color, ease D And the application, ease of production, with excellent appearance and chemical stability in different environments.The object of the invention process applied in coatings proved entirely satisfactory for producing formulations with the microstructural characteristics and technological properties higher than those found in the market and proposing the same purpose.
