Abstract

L'invention concerne un abrasif synthétique, comprenant les constituants suivants : polypropylène, polyéthylène, un matériau abrasif et un lubrifiant. Le matériau abrasif est un oxyde d'aluminium, une poudre de quartz et/ou une cendre volcanique. L'abrasif synthétique a une grande résistance à l'abrasion et une grande résistance aux chocs, et n'exige pas l'addition de matériaux abrasifs ni de consommation de bois et favorise donc la protection de l'environnement; de plus, après une utilisation répétée, les déchets peuvent être recyclés, ce qui facilite la réduction du coût de production.
