Analysis of the raw clay

Before development of modern plants designed for production of ceramic building materials or reconstruction of the old ones it is virtually important to conduct thorough physical, chemical, and technological researches of basic clay raw materials.

Such researches,done using modern precision instruments and applyings cientific methods,are necessary for future production parameters and technologies optimization. Those give an answer to many questions concerning equipment selection minimizing costs and risks even before the construction works begin.

For example, expert thermaland dilatometric analyses of clay raw materials, which are essential when conducting their physical and chemical researches, allow considering every peculiarity of their behavior during heating and cooling processes. This provides correct development of firing conditions of semi-products adjusted to specific raw materials and ultimately helps to save fuel.

As experience has shown, dilatometric researches of raw materials help to achieve a 2-3 time reduction spent on installation and start-up works. In addition to this, the data obtained in the result of complex physical, chemical and ceramic-based technological analysis of raw materials permits to validate the choice of raw materials, to optimize batch composition and to forecast properties of future ceramic products. They are also required for the development of documentation on manufacturing processes regulations.

Considering the latest trends in the market of ceramic building materials, technologies of their manufacturing as well as production problems of enterprises of ceramic industry and its raw materials specialties we develop the following work streams:

- complex study of clay raw materials for ceramic building industry and providing recommendations onhow to adjust its technological properties;

- study of plastic ceramic bodies shaping properties using a model of industrial vacuum press;

- study of drying properties  of clay raw materials and ceramic bodies with the following validation of production drying and firing conditions of semi-products;

- determination of reasons of efflorescence on facing ceramic products and development of the methods of their elimination;

- development and optimization of compositions of technological compounds and technological parameters of common, facing, clinker ceramic products as wellas refractory bricks and thermally insulating refractory materials obtained using the technology of plastic shaping and dry pressing;

- invention of scientific methods for forecasting are as of industrial use of compound clay raw materials;

- development of energy-saving solutions using various kinds of fuel and fuel additives;

- development of technology of heat-efficient wall ceramics (high-hollow ceramic stones, porous hollow blocks, efficient bricks);

- manufacturing of facade ceramics of wide color range using natural and man-made chromophoric additives;

- optimization of structural-rheological and shaping properties of ceramic bodies using industrial chemical products and their substitutes for manufacturing goods using stiff and semi-stiff extrusion;

- manufacturingofbuildingmaterialswithhigh-utilizationdegreeofindustrialwaste (facade ceramics using waste coal flotation as mineral supplements and basic raw materials, chemically bonded construction products on the basis of zoloschelochnogo binder, fly ash as a substitute for CHP fusible clays, granular backfill material for road-based drilling mud, etc .).

In addition to the main are as of focus listed above we conduct works on development of technological parameters of granulated products for various functional purposes (fuel, filters, fertilizers, pigments and other).

PLINFA Engineering and Industrial Group is the solution of complex tasks in manufacturing of ceramic building materials.
