Laboratory of Polymer Composite Material in Shipbuilding

The Lab subordinates to the department of Transport Technologies

at the ESR spectrometer

The Laboratory Goals:

  • establish basic laws of influence of energy fields and the fillers on the mechanism of polymer composites formation and to issue recommendations on developing functional coatings to protect technological equipment from corrosion and wear-out;
  • verify working hypotheses about the interconnection within basic physical, mechanical and thermal properties of composites and the development of software for verification of numerical experiments.

The result of the work would be the development of the ability to predict one or more properties of a composite material with reasonable accuracy.

Research and applied activities:

Tensile Machine UM-5

  • development of new technologies and materials with improved performance characteristics for protecting ship hulls;
  • study the impact of physical fields on the properties of composite materials;
  • nanocomposites and nanotechnologies in modern industry;
  • and use of information technologies in modeling complex systems and predicting their properties.


Research tasks:

IR spectrometer IRAffinity-1 (Japan)

  • develop methodological approaches to the study of energy fields effect (magnetic, ultrasonic, ultraviolet radiation) on the properties of polymer composites;
  • find out the mechanisms of interphase interaction of dispersed and fibrous fillers with polymer binding at the nano-, micro-and macro-levels;
  • investigate the effect of the filler on the surface characteristics at the interphase "polymer - filler" (density, degree of crosslinking, geometric size);
  • issue some recommendations to produce coatings of different functional purpose on the basis of the developed composite and introduce them into industry.

At present, the laboratory is provided with modern equipment to study the structure (EPR and IR spectroscopy), the physical and mechanical properties (tensile machine, Tovarov’s device, Sokslett’s device, rotational viscometer), thermal properties (heat resistance, DTA, DTC, TEC, dielectric characteristics) and wear resistance of polymer composites (friction machine).

One of the projects the laboratory is developing today is designing the modified composite materials for coatings in shipbuilding.

THE INNOVATION IDEA

The idea of the project is to study the influence of the physical properties of the fillers, magnetic treatment, ultrasound and ultraviolet irradiation on physical, mechanical, and thermal properties, corrosion resistance and wear resistance of the protective coatings. In order to determine and optimize the structure of the coatings and modes of magnetic treatment, ultrasound and ultraviolet radiation, as well as the foreseen structure and properties of heterogeneous materials, it is provided to develop managing mechanisms of the interaction at the interphase level "basis –polimer composite coating." The study will suggest methods to control adhesion, corrosion, physical and mechanical properties and wear resistance of heterogeneous materials by using fillers of different magnetic properties. The outcome of the study will be development of a new epoxide-composite coating to protect technological equipment from corrosion and wear-out.

PRODUCT

Viscometer BRUKFIELD (Germany)

As a result, new composite materials and coatings have been created with predictable performance to protect technological equipment from corrosion and wear.

New materials, methods and ways to improve protective coatings resistance to corrosion and wear-out have been developed, and protected by patents of Ukraine. Multilayer coatings based on epoxide-composite materials provide high performance and are suitable for surface protection of technological equipment from corrosion and waterjet.

The implementation of the results is possible in the Kherson region shipyards, which are engaged in testing process to improve corrosion and wear resistance characteristics of the processing equipment. In addition, the results can be implemented in chemical, food processing, oil refining, radar and mechanical engineering industries in order to increase the service life of the equipment.

PROBLEM / OPPORTUNITY

Today, not enough attention is paid for the development of new epoxy-composite materials by modifying the ingredients and compositions by impact of external energy fields at the initial stages of their formation. It makes possible to open up entirely new possibilities in the creation of new protective coatings with improved characteristics. Therefore, investigation of cross-linking of epoxide-composite materials under the influence of a magnetic field, ultrasound and ultraviolet irradiation to improve the performance of protective coatings is an important task of modern industry.

FIELD OF APPLICATION

Ultrasonic dispergator UZDN-A (Russia)

The advantage of this device is ability to account the major factors of dispersive medium, where equipment is used and development new materials, which have high rates of physical, mechanical, thermal properties, corrosion resistance and durability. The technological process of the polymer composite materials formation will meet the level of technologies that are being developed in Belarus, the Baltic States, Russia, Germany, USA and Japan.

All ingredients of composite materials and coatings based on them (epoxy, plasticizers, fillers) are located in Ukraine. At the same time, such particulate fillers, like red and brown sludge, carbon black, ferrite are industrial wastes, so this technology introduces the economic efficiency of the production of new materials.

In addition, employees of Kherson State Maritime Academy have designed proper technological equipment (unit for the magnetic treatment, ultrasound and ultraviolet irradiator) for the treatment of oligomeric compositions by the external energy field impact.

INTRODUCTION OF THE COATINGS PROVIDES

  • improving the corrosion resistance of the equipment in 2.5-2.7 times;
  • wear resistance in 2.0-2.2 times;
  • and increases the period between overhauls in 3.0-3.5 times

OFFERINGS

Implementation of the research is possible at all shipyards in the Kherson region, which are engaged in testing structural elements, improving corrosion and wear resistance characteristics of the processing equipment. In addition, the implementation of the results is possible in chemical, food processing, oil refining, radar and mechanical engineering industries in order to increase the service life of the equipment.
