Production of radiation destructant from spent butyl rubbers on the linac LU-10-20

Abstract

Radiation methods of materials modification applied in technological chains can have significant economical and ecological advantages as compared to the established chemical, thermal and mechanical methods. Each year the problems of nature resources economy through the use of production and consumption wastes acquire a more significant value, as it allows to solve also ecological issues along with economical ones. This is mostly acute in relation to polymeric systems based on saturated rubbers, for example butyl rubber (BR) used in tyres industry, as due to their high resistance to the action of oxygen, ozone, solar radiation and bacteria they contaminate the environment for rather a long period. At VNIIEF and KSPU there were carried out experiments on application of electron beams with energy from 6 to 10 MeV for radiation destruction of spent rubber based on butyl rubber. Reclaim is tested in the formulation of initial diaphragm mixture, rubber mixture for producing rubberized fabric, roofing.
