Description

Наблюдающеес  при регенерации измельченной резины и других технических процессах почернение вызываетс  образованием сернистого свинца.The blackening observed during the regeneration of ground rubber and other technical processes is caused by the formation of lead sulphide.

Предлагаемый способ имеет целью устранить почернени  вулканизированной резины и заключаете в кип чении измельченной резины с IVo раствором азотной кислоты, вследствие чего все свинцовые соединени  раствор ютс  и вулканизированна  резина сохран ет первоначальную окраску. П1редмет патента.The proposed method is intended to eliminate blackened vulcanized rubber and boil ground rubber with IVo nitric acid solution, as a result of which all lead compounds dissolve and vulcanized rubber retains its original color. Patent of the patent.

Способ обработки вулканизированной резины с целью удалени  из нее свинцовых соединений, отличающийс  тем, что измельченную вулканизированную резину обрабатывают на кипу слабым раствором азотной кислоты.A method of treating vulcanized rubber to remove lead compounds therefrom, characterized in that the crushed vulcanized rubber is treated on a pile with a weak solution of nitric acid.
