Definitions

  • Patent is related to clay production (bricks etc.), ceramic tile production or any other industry which uses clay material, with possibility of usage in construction or building in general.
  • Our patent is additive which is effective, inexpensive in the forming of clay products, especially in the extrusion of brick, tile or sewer pipe. It is an excellent plasticizing and deflocculating agent. The amount of water that is needed to be added at the pug mill is significantly reduced or completely obsolete.
  • Second parameter is the request that input material - clay contains enough water for the homogenization in the preparation process (maintaining the plasticity of clay needed for the extrusion in pug mill) and the second is limited water removal during extrusion process. Therefore, to implement the whole process successfully, one must input additional water content and after that water must be removed in the drying process before the baking process. Otherwise, if the green bricks are not sufficiently dried, they crack during baking process and are completely unusable. Green bricks, depending on the type of the soil, usually contains between 16 % and 24% of water.
  • Ceramic materials have long been used in a wide variety of applications, including as roofing material and, more commonly today, as floor and wall coverings in homes. Innumerable formulations have been devised to produce kiln-fired ceramic materials having the appropriate properties for the desired end use. Traditional examples of those ceramic formulations include those which contain either shale or clay as the primary component. In the geramic production industry where no extrusion is required, the problem is existence of the calcium carbonate (CaCO 3 ) which on high temperatures (above 900° Centigrade) burns and creates a gas which than can damage surface of the glaze. Therefore two baking stages are in such circumstances required in order to remove calcium carbonate prior baking glaze. Disclosure of the Invention Plasticity of the natural unmodified clay depends of water content and acidity of the soil
  • Plasticity can be adjusted by maintaining acidity of the soil by using our patented additive which is composed out of two components.
  • First component is sodium - silicate (Na 2 O) n (SiOi) nI (H 2 OX commonly known as "water glass”.
  • Sodium - silicate (or natrium - silicate) has downside effect to plasticity of the clay since it decrease acidity (pH) of the soil.
  • second component which is concentrated (75% industrial) phosphoric acid (H 3 PO 4 ).
  • These two components which forms additive are sodium - silicate and phosphorous acid. They are induced into the soil by mixing with the inert dry material (e.g. sand).
  • the function of the inert dry material is to equally distribute additive and to reduce wet content of the clay. Simply in the 1000 kg of the soil between 10 % and 20 % should be replaced with the inert dry material previously mixed with the additive.
  • Natrium - silicate is added in the following rate: 10 kg per 1000 kg of the soil.
  • Phosphoric acid is further added in the following rate: 4 kg per 1000 kg of the soil.
  • Inert dry material used for additive distribution can be sand, fine grounded rejects from the clay production (broken bricks, etc.).
  • Important thing for the inert dry material is that when exposing to the high temperatures while baking does not produce gases and has an extremely low water content.
  • Green bricks, depending on the type of the soil, usually contains between 16 % and 24 % of water, as compared to our method where one can completely avoid any water addition in the production process. The water content can be reduced to 10 % - 14 % in the green bricks or any other clay products that requires extrusion.
  • drying time is significantly reduced with the baking time which results in production rate, energy savings and quality.
  • phosphoric acid can be used in order to completely remove calcium carbonate as carbonate salts.
  • phosphoric acid is added as a water solution directly on the soil.
  • the time of the contact between the soil and phosphoric acid is related to the size of the particles of the calcium carbonate. It is recommended that adding is done prior pug mills in order to equally distribute acid in the soil.
  • sodium silicate (natrium silicate)
  • sodium silicate is much easier to add as a previously mentioned mixture with dry inert material such as sand, while adding phosphoric acid has to be previously arranged as a mixture with the original soil for better reaction with calcium carbonate.
  • the percentage of dry inert material (e.g. sand) for such purposes is between 3% to 5% without any side effects (no change in color).
  • the best possible implementation is to introduce sodium silicate mixed with dry inert material (e.g. sand) and then, depending on the volume of soil, calculate concentration as described in previous article.
  • the sodium silicate mixture with sand should be introduced prior any mills in order to allow the best possible homogenization of mixture and the soil.
  • Phosphoric acid than should be introduced just before extruder (water solution) in the concentration as described in previous article.
  • industrial wastage like fly ash or other industrial wastage in particles can be used in above described process as dry inert material. This can lead to ecologically safe removal of potentially hazardous material thus lowering costs of brick production.
  • This patent can be used in any industry that involves clay production or ceramics production as described in previous article. Also, it can be used as a ecologically safe method for removal of industrial wastage. Introduction in the industry is seamless and easy. It does not involve any additional equipment because any clay industry already posses pug mills and water distribution systems that can be easily adjusted for our additive disposal system.

Abstract

La présente invention concerne l'ajout d'une matière inerte ayant une très faible teneur en eau (par exemple du sable), modifiée avec un additif afin de réduire la teneur en humidité et de maintenir la plasticité de l'argile. Simplement, on devrait remplacer entre 10 % et 20 % de 1000 kg de la terre par la matière sèche inerte préalablement mélangée avec du silicate de sodium (Na2O)n(SiO2)m(H2O)k et de l'acide phosphorique (H3PO4) ajoutés séparément. On ajoute le silicate de sodium en proportion de 10 kg pour 1000 kg de terre glaise et on ajoute l'acide phosphorique séparément en proportion de 4 kg pour 1000 kg de terre. La matière sèche inerte utilisée pour véhiculer l'additif peut être du sable, des déchets finement broyés provenant de la production d'argile (briques cassées, entre autres). Il est important que la matière sèche inerte, lorsqu'elle est exposée à des températures élevées lors de la cuisson, ne produise pas de gaz et ait une teneur en eau extrêmement faible. Les briques vertes, selon le type de terre, contiennent habituellement entre 16 % et 22 % d'eau. En utilisant notre invention et en évitant complètement tout ajout d'eau au cours du procédé de production, on peut réduire à 10-14 % la teneur en eau dans les briques vertes ou n'importe quels autres produits d'argile. Par conséquent, la durée de séchage et la durée de cuisson sont considérablement réduites, ce qui entraîne un meilleur rendement de production, des économies d'énergie et une meilleure qualité. Lors de la production de céramiques, ou lors de la production de n'importe quel produit d'argile où le problème repose sur la présence de carbonate de calcium (CaCO3), on peut utiliser l'acide phosphorique afin d'enlever complètement le carbonate de calcium sous forme de sels de carbonate. L'acide phosphorique est ajouté en fonction du pourcentage de carbonate de calcium en proportion de 0,0066 litre pour chaque kg de terre contenant 1 % de carbonate de calcium.
