COMPOSITION OF SEPARATOR FOR CLEANING PIPE AND SEPARATING MEDIA AND METHOD OF ITS MANUFACTURE Russian patent published in 1998 - IPC

FIELD: cleaning pipelines and separating media. SUBSTANCE: used as structure forming components are the following components: rubber or 10-30-% solution, solvent - oil, diesel fuel or kerosene, filler - bitumen, component for cross-linking of molecules of structure forming components - monochloric sulfur at the following ratio of components per unit of volume of separator V^* = 1 cu.m: solvent, 678.9/790.4 kg/l (diesel fuel, kerosene, oil), bitumen, 119.2 kg; rubber, 19.8 kg; monochloric sulfur, 5.9/3.5 kg/l; the required weighted portions of each component per definite volume M_i= M_oi•V^*/V_o are found from the following formulae: M_i, where M₁ is mass of i-component; i, 1-4 (M₂ - solvent; M₃ - bitumen; M₄ - rubber, and M_oi - monochloric sulfur); V_o is mass of each component of i-component per volume unit V^*; V^*= SL - volume of separator determined from relationship M₁, where S is section of pipeline and L is length of separator. Monochloric sulfur is introduced in the form of solution into solution of structure forming components at normal or at reduced or increased concentration; amount of solvent reaches 20% of total mass fraction. EFFECT: enhanced efficiency.
