METHOD OF MANUFACTURE OF LOW-MOLECULAR RUBBER AND ROTARY APPARATUS FOR REALIZATION OF THIS METHOD Russian patent published in 2002 - IPC

FIELD: methods and devices for mixing and dispersing homogeneous media for manufacture of low-molecular rubber from high- molecular rubber; chemical, petrochemical, food-processing and pharmaceutical industries for production of polymer products and pastes. SUBSTANCE: according to proposed method, low-molecular rubber is manufactured by zones of rotary apparatus, mainly by three zones. In first zone, starting material is subjected to break-down plasticization with rotor revolving at speed of 5-1000 r/min. Next zone is used for destruction of broken-down starting material due to dissipation of mechanical energy with rotor revolving at speed of 500-7000 r/min. Last zone is used for degassing of destruction product and additional (if necessary) thermal destruction and homogenization and cooling due to control of speed of its motion from 30 to 200 r/min. Rotary apparatus proposed for realization of said method includes housing with cooling jackets, loading and unloading branch pipes and working members made in form of rotors. Each zone houses at least one rotor revolving at preset speed; rotors are located at angle of 0-180 relative to one another. EFFECT: intensification of dispersion and/or homogenization process; control of process of production of material at required complex of properties. 11 cl, 3 dwg
