PURPOSE:
The development is aimed at creating an energy-saving technology for functional ceramics for tank lining, manufacturing ceramic nozzles for filling heat-exchange columns and absorbers, equipping pumps for pumping aggressive liquids, producing tanks for melts, ceramic sealing rings for rotating shafts of automobile engines, etc.
TECHNICAL CHARACTERISTICS:
The scope of application of functional ceramics has been significantly expanded: it is characterized by equally high rates of acid and water resistance (> 99%); due to the synthesis of thialite, the thermal resistance of materials increases (> 8 thermal cycles from 350 to 20 ° C); due to the synthesis of mullite, the strength of ceramics increases (σ = 27 MPa, σst = 110 MPa).
RECOMMENDED FIELD OF APPLICATION:
The development can be effectively used in chemical, construction, metallurgical, machine-building and other industries.
ADVANTAGES:
The developed high-resource functional ceramics in comparison with world analogues (LLC “Kislototriv Stroyzakhist”, LLC “Promkeramika”, Rauschert GmbH Technische Keramik & KunststoffFormteile) has a lower firing temperature (1250 ° C versus 1280-1350 ° C); characterized by both high acid and water resistance (99.4-99.9 and 99.99%, respectively); world analogues are characterized by high indicators of only acid resistance (97-99.98%). The thermal resistance of the developed ceramics is> 8 thermal cycles (from 350 to 20 ° С), and the maximum temperature of use is 1200 ° С compared to 2-8 thermal cycles and 1000 ° С for existing analogs. The advantage of the developed materials is a decrease in the temperature of their formation from 1300 to 1250 ° C and the possibility of using industrial waste while maintaining high-performance characteristics.
DESCRIPTION:
The created high-resource ceramics, which, together with a set of specified parameters, has an additional resource of properties, which increases its durability and expands the scope. Developed high-resource and vitreous materials with a complex of both standard and new specified properties (high thermal efficiency, chemical and biocorrosion resistance, self-cleaning and bactericidal qualities). The developed materials are characterized by increased constructive quality and prolonged service life under conditions of variable temperatures, exposure to aggressive media and biocorrosion load.
