THOROUGH REVISION OF AUTOMOBILE TYRES
In fuel oil for boiler rooms
There is a continuous accumulation of worn
splints, basically with a metal cord, and only about 20 % from
the whole is processed. Worn splints represent the most large-capacity
production of the waste products containing polymer which practically
have not been the subject to natural decomposition. That is why the
thorough revision and secondary use of the splints which have left
operation have the important economic and ecological value.
Splints represent valuable polymeric raw material:
about 700 kg of gum which can be reutilized for manufacture of fuel,
industrial rubber goods and materials of building destinations is
contained in 1 ton of splints. At the same time at combustion of 1 ton
of worn splints 270 kg of carbon black and 450 kg of noxious gases are
secreted in an atmosphere.
The highest level of a thorough revision of worn
splints reached in Japan (99 %) and Germany (88,4 %). In countries CIS
the thorough revision of worn splints is on a low level owing to
absence of intrinsically safe equipment for their thorough revision.
Recently waste products of solid organic materials,
including worn tyres (covers), draw attention as a potential source of
obtaining of an oil stock and fuel more and more.
