Title (EN) A WEAR-RESISTANT RUBBER PRODUCT AND A METHOD OF MAKING SAME
(FR) PRODUIT DE CAOUTCHOUC RESISTANT A L"USURE ET PROCEDE DE FABRICATION DE CELUI-CI
Abstract: front page image
(EN)A wear-resistant rubber product adapted to be used as, for example, a lifter in grinding mills, comprises at least two prefabricated parts (11, 12) interconnected with one another by means of a binder layer having a thickness of at least 2mm and consisting of in situ cast and cured polyurethane. The wear-resistant rubber product is manufactured by placing the prefabricated cured rubber parts (11, 12) at a distance of at least 2mm from one another and by introducing, preferably injecting a reacting urethane rubber composition with excess isocyanate groups into the gap (13) to cause said prefabricated parts on either side of said gap to be contacted substantially simultaneously by the said urethane rubber composition.
(FR)Un produit de caoutchouc resistant a l"usure convenant, par exemple, pour etre utilise comme dispositif de levage dans des broyeurs, se compose d"au moins deux parties prefabriquees (11, 12) liees entre elles au moyen d"une couche de liaison d"une epaisseur d"au moins deux millimetres se composant de polyurethane coule et vulcanise sur place. Le produit de caoutchouc resistant a l"usure est fabrique en placant les parties prefabriquees de caoutchouc vulcanise (11, 12) a une distance d"au moins deux millimetres l"une de l"autre et en introduisant, de preference par injection, dans l"interstice (13) une composition de caoutchouc d"urethane avec un exces de groupes isocyanate de sorte que les parties prefabriquees de chaque cote dudit interstice soit en contact sensiblement simultane avec ladite composition de caoutchouc d"urethane.
