Definitions

  • the invention is composed of the production processes applied for obtaining Sepiolite with a high rheological level and the resulting product.
  • Sepiolite is a clay mineral which is composed of magnesium hydrosilicate. It is used as an admixture material in various production areas owing to its fibrous structure, crystal morphology, high surface area, surface activity as well as its absorptive, catalytic and especially rheological characteristics.
  • Sepiolite has mainly a fibrous structure and there are internal channels throughout this fiber structure. Thanks to this structure, Sepiolite has a high level of absorption and it can retain water several times of its weight. Contrary to other clay minerals like Bentonite, during the water retention of Sepiolite, no expansion is experienced in its volume. Such characterization provides an important advantage to the Sepiolite and its areas of usage.
  • Fibrous structuring which constitute the source of rheological qualification of Sepiolite stand as bundles/clusters which look like ‘shrubs and grass’ Stacks.
  • Patents numbered EU Patent 0.170.299, US Patent 3.951.850, US Patent 3.999.068 and US Patent 3.509.056 in which methods of minimum 90% aqueous hydrocyclone, wet-milling and aqueous decantation/ disassociation/ disagglomeration methods with chemical agents are used in order to develop rheological qualifications of above mentioned minerals and in order to enrich/ modify the mineral, can be given as an example.
  • the invention ensures that Sepiolite is gone through correct and serial mechanic/ physical processes and bundled/ clustered fibers are enriched/ modified by aligning/ setting/ elongating in the right direction without being damaged/ broken.
  • Sepiolite which was brought to a superior level in terms of its rheological qualifications as a result of the invention confines/ holds the liquid within its 50 content and in its surrounding by easily dispersing in the water or high-low polarity dissolvers and it increases the suspension viscosity by this way.
  • the invention is the production process applied for obtaining Sepiolite with a high rheological level which ensure that Sepiolite is gone through correct and serial mechanic/ physical processes and the bundled/clustered fibers are enriched/ modified by aligning/setting/elongating in the right direction without being damaged/ broken and the resulting product.
  • the invention was considered to bring out a productive and less costly method with respect to the current methods and procedures applied for obtaining Sepiolite with a high rheological level.
  • both the usage areas of the product would be enlarged and the yield from the product and its value-added would increase.
  • Clay mineral material which has a minimum 50% Sepiolite in its content is extracted from the mine by selecting it in its natural habitat.
  • the Sepiolite material humidity rate of which was set to 40-60%, is planed/cut through pressurized plane type or pressurized blade cutter machine in a way to obtain a thin chip (planed product) material.
  • the process is carried out without pulling apart the fiber structures which are in a coherent state in the natural structure of the material.
  • the pressurized planing/cutting process also ensures fiber structures to be aligned/set and elongated in the right direction through compacting/crushing and thus, the enrichment / modification process is performed.
  • the material whose rheological qualifications are enriched/ modified by this way is heedfully dried below 300°C to have 6-13% moisture in its content.
  • the dried chips obtained as a result of this process can be placed on the market in order to be used in production processes where high rheological levels are required.
  • Sepiolite which has reached the chip-phase can be grinded at desired micron size to be able to be used in the fields in which micronized materials are needed in terms of rheological levels and easy application.
