Chemical Technology Composite Materials

Plastic, elastomers, composers and other materials production: plastisoles, foam and adhesive materials, laminates material - based, protective coatings and etc.

The main directions of scientific work of the Department formed last 5 years.

  • The theoretical foundations of forecasting of inorganic and polymer composite materials stability under the influence of operating, atmospheric and biological factors have been developed.
  • The effective methods of ensuring the recession level of exploitation composite resistance by weakening the aggressive environment action (including effective and reliable compact radioactive and toxic pollutions and waste) by special element organic coverings, saturated by monomer and polymer solutions, new types of poly concentrate have been created (Doctor of Techniecs, Professor V.A.Sviderskyy).
  • The effective constructional materials on the bases of inorganic binding materials, which are used for the hydro isolation in compacting radioactive waste, conservation and transporting of toxic pollutions and chemical poison have been developed (candidate of Technics assistant professor V.V.Glukchovskiy).
  • Investigation in the field of chemistry and technology of mineral binding materials (mainly cements) and their usage sphere.
  • The development of special cement composition (including increasing and tensing). The usage of industrial waste in the production of binding materials (Doctor of technics professor V.A.Sviderskyy).

The scientific achievements of the Department

The following developments can be classified as the scientific achievement:

  • Development of the compact of liquid radioactive waste (LRW) technology. 
    The principle of this technology is mineral binding material (cement, which is hardening under pressing - contact-condense bindings. The peculiarity of these cements is the absence of water during their hardening. Contact hardening binding is the mineral disperse powder which forms stonelike waterproof body with the strength of compression 20-30 Mpa and water absorbtion 3-5%, right after pressing at the pressure 40-60 Mpa. Compounds on the base of these bindings enlarge theirs strength with the time.
  • Development of immobilized and compact solutions technology, which contain tritium.
    Ihe usage of contact hardening bindings allows to develop the technology of the LRW Immobilization which contain tritium. This technology allows completely link LRW which contains tritium in mineral compounds which contains in volume 50% of mineral forming and 50% of water, which in its rum contains tritium. The destruction of the compound occurs at the temperature above 500°С with the separation of bound water which contains tritium.
  • Development transport - defense containers for saving and bury radioactive waste (RAW)
    Transport defense container is used for transporting safe and permanent (not less than 300 years) saving solid RAW no more than group II.
  • Development of dust collection compounds and the technology of carrying out dust collection works.
    Compound are used for the preliminary processing territories open storehouses, places of saving toxic or RAW and materials, surfaces of engineering constructions before dismantling. It secures all round dust - collection, strength of covered surface - 2,0-10,0 Mpa.
  • Development of lightly deactivated coverings.
    Storehouses are used for the reduction of the level of fixed radioactive waste of building constructions, transport, technological equipment, containers.
  • Development of transport - defense containers for safe and long storage ecologically dangerous and toxic waste.
    Transport - defense container is used for transporting of safe and permanent (not less then 100 years) storage ecologically dangerous and toxic waste of I and III danger classes.
  • Development of glasscement constructional hydroisolation.
    Constructional hydroisolation is used for ensuring impenetrability of capacity for saying fresh and sea water, cleansing construction, storehouse of petroleum products and pumping stations. It is traced on concrete, brick, wood bases and just on the ground.
  • Development of glasscement fabric - based laminate hydro defense forms of heat isolator pipelines.
    Glasscement fabric - based laminate is used for the protection from the atmospheric influence of heat isolation of pipelines and equipment which is situated in and outside the construction, tunnels and impassable channels.
    Glasscement fabric - based laminate can be curved as easily as cardboard, twist in rolls and unroll in a sheet.
  • Development of constructive elements of irrigational systems, water pipelines, drainages, canalizations.
    New constructive elements of irrigational systems are characterized by the reduced specific consumption of materials (5 times lower than traditional elements), increased crack resistance (30 times higher than ferroconcrete), longevity and corrosion resistance. They are used for the subsoil waters level control, drainages, diversion polluted water flows in clearing systems.
  • Development of heat insulator and constructive products on the base of conversion of wood waste.
    They are used for the construction of dwelling, industrial, agricultural buildings as hand outward walls, filling frames, carrier outward and inner non-reinforced building walls up to the second floor, lining of ceiling, floor and roof They reface to the bioresistant materials which are hard to burn.
  • Development of building concretes, products and constructions on the base of multi-tonnage waste of the metallurgical production (domain granulated slugs). The technology allows making highly effective building products and contractions on the base of multi-tonnage waste of the metallurgical production, domain granulated slugs without using the portland cements.

Development of polyfunctional silicon organic coverings, paints, enamel.
The compositions and technologies of silicon organic coverings production have been developed They are characterized high and long heat resistance (up to 600 °C), non combustibility, non toxicity. atmosphere-resistance (10-15 years), hydrophoby. low temperatures resistance, high dielectric characteristics, detute alkali solutions and inorganic acids stability. Modified silicon organic coverings of different types of organic binder and functional additive allow increasing their usage.
