A widespread method for utilizing rubber-containing waste is incineration, which leads to an increase in the volume of pollutants in the environment. A method is proposed for processing waste into ecologically safe waterproof materials.Extensive use of rubber-containing objects leads to the accumulation of signifi cant amounts of synthetic rubber waste. An increase in the amount of synthetic rubber waste amenable to utilization (SRWU), sent to centers for temporary accumulation or storage, and cases of their unauthorized burning or placement on the surface of soil point to poor development in the sphere of SRWU processing. Forms, types, and shapes of synthetic rubber vary: industrial and domestic rubber objects that have lost useful properties; used tires with fabric or metal cords, etc.The most widespread and technologically simple method of utilizing and dumping SRWU is burning with the aim of obtaining energy. Synthetic rubber waste is a fi re hazard, and contaminating substance discharges have an unfavorable effect on ecological systems.In addition, synthetic rubber waste is a source of hydrocarbon raw material, textile material, and alloy steel scrap (in the form of artifi cial and natural fi bers). The main components of rubber-containing materials and objects [3] are rubber mixtures, commercial grade carbon, silicic acid, oils and resins, sulfur, vulcanizing activators, and ecological fi llers.There are numerous methods for breaking down SRWU [4]. Comminution is energy consuming and complicated both with respect to determining the nature, amount, and direction of loads, and also diffi culties in qualitative and quantitative estimation of the comminution results.The authors suggest a production process for utilizing rubber-containing waste and manufacture of waterproof materials from it. The main production operations of the process are: 1) synthetic rubber waste preparation for utilization; 2) loading one or several forms (types) of SRWU into a bunker; 3) SRWU mechanical comminution with preparation of rubber crumb and associated components [5]; 4) laying SRWU rubber crumb into molds; 5) pressing rubber crumb with established parameters (temperature and pressure); and 6) cutting and packing waterproof material obtained. A line for SRWU processing (Fig. 1) and waterproof material preparation (productivity 10 tons/day) should be located within a heated building with an air temperature of 15-20ºC, and atmospheric pressure 745 mmHg.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
