Abstract

LE PRODEDE SELON L'INVENTION A POUR BUT D'AUGMENTER LA LIMITE ELASTIQUE ET LA DENSITE DU TEREPHTALATE DE POLYETHYLENE ET AUTRES MATIERES PLASTIQUES SIMILAIRES SUSCEPTIBLES DE DURCIR PAR TENSION. ON CONDITIONNE THERMIQUEMENT LA MATIERE PLASTIQUE JUSQU'A UNE TEMPERATURE SE SITUANT DANS UNE GAMME FAVORISANT UNE ORIENTATION MOLECULAIRE PUIS ON LA CONDITIONNE MECANIQUEMENT EN L'ALLONGEANT DANS UNE PREMIERE DIRECTION JUSQU'A CE QU'ELLE AIT UNE LONGUEUR EGALE A AU MOINS ENVIRON 2, 6-2, 75 FOIS SA LONGUEUR INITIALE. ON ETIRE ENSUITE LA MATIERE PLASTIQUE DANS UNE SECONDE DIRECTION, LE DURCISSEMENT PAR TENSION ET LA CRISTALLISATION INDUITE PAR TENSION AUGMENTANT CONSIDERABLEMENT LORSQUE DEBUTE LA SECONDE OPERATION D'ETIRAGE PAR SUITE DU CONDITIONNEMENT MECANIQUE PAR ALLONGEMENT PENDANT LE PREMIER ETIRAGE. APPLICATION: FORMATION DE RECIPIENTS MOULES PAR SOUFFLAGE.
