Abstract
4803. Duwez, O. F. J. March 6. India-rubber, devulcanizing.-Old vulcanized rubber is kneaded as thin as is possible and boiled for some time with water and finely-powdered lime, which has been heated to a temperature considerably higher than that necessary in the manufacture of lime. Cement or other materials containing lime, which have been highly heated, may be used instead of lime. Sugar, salts of lead, baryta, glycerine, caustic alkalies, or carbonates may be added to the mixture. The rubber is afterwards washed and rolled, and can be re-vulcanized. Lime of the kind described is stated to form a soluble hydro-sulphate with the extracted sulphur.
