METHOD OF PIECES PRODUCTION OUT OF COMPOSITION MATERIALS Russian patent published in 1997 - IPC

FIELD: production of pieces out of composition materials, method is used at enterprises producing ecologically safe production out of wastes of wood-working industry. SUBSTANCE: filler, for example, wood components is mixed with thermoplastic binder, mixer is heated and subjected to cold or hot moulding. Directly before mixing filler and thermoplastic binder are subjected to action of electrostatic fields. Binder is fed in zone of electric field action in finely dispersed state. Amount of thermoplastic binder coating filler during mixing is controlled by value of electrostatic field intensity. As a version filler or thermoplastic binder is subjected to action of electrostatic field. Method allows to produce pieces with high physical and mechanical characteristics, to decrease to minimum thermoplastic binder consumption, to avoid toxic extractions, to make piece material structure close to structure of filler. EFFECT: production of pieces with high physical and mechanical characteristics, decreased to minimum thermoplastic binder consumption, excluded toxic extractions, piece material structure is made close to structure of filler. 1 dwg
