Текст статьи The use of carbon containing solid residue of pyrolysis of disused tires

To date the greatest interest from the products of pyrolysis of rubber products is carbon black (soot). In the literature there are recommendations on the possibility of using this carbon residue (UTO) as a pigment in the paint industry, filler in Rezina industry and for the production of sorbents. But in order to use UTO or where it is necessary to know its specific properties. However, the RTI processors provide insufficient characterization of the physico-chemical properties of the UTO. [1].

The aim of this work was to study the physico-chemical properties of the UTO received on installation goes out on the company "Connectology plus" (Kaltan). The raw material used disused heavy tires (CGS), which contains 90% natural rubber, which has a significant influence on the properties of the resulting UTO. The results of the experiment are presented in the table:

Physico-chemical properties	Values
pH of aqueous suspension	5-7
Analysis moisture (W^а), %	0,4 ± 0,03
Ash, W - %	0,3±0,1
Bulk density, kg/m³	318±0,2
Dispersion microns, not more than	10-40
Absorption of dibutyl phthalate, cm³/100	65±6

Mass fraction of sulfur, %	2,4±0,2
Oil absorption, g	114,5

The obtained results do not differ from similar characteristics of carbon number П701, П705, П803 produced from traditional raw materials (gas, coal, oil) according to the known technology (furnace, etc). Thus, the carbon black obtained by pyrolysis, can be used as pigment in the paint industry and in construction.

Industrial use of the obtained product is currently in paint and varnish factories, Novosibirsk, Tyumen, Urals. [2].
