Title Removing contaminants from the air in recycled rubber sole production
Original title Očistka vozduha ot vrednyh vybrosov v proizvodstve podošvennogo regenerata [in Russian]
Bibliographic information Sep. 1987, No.9, p.16-18. Illus. 3 ref.
Abstract Air sampling around the extruders of rubber devulcanisers in several plants showed that the principal contaminants emitted by black regenerated rubber are styrene and plasticiser fumes. Ammonia is emitted only when plasticisers have been used in the rubber. An experimental device with a capacity of 100m3/h for cleaning the air collected by local exhaust systems was constructed and tested. In the device, the air is bubbled through MP-75 oil, then passed through a bed of fluorinated plastic chips and a glass fibre filter. The device reduced plasticiser fume levels by as much as 97.4%.
