A hose includes a fluorothermoplastic tube layer, a nitrile rubber friction layer disposed over the tube layer, a reinforcement layer disposed over the friction layer, the reinforcement layer comprising braided steel wire, and a cover layer disposed over the reinforcing layer, where the cover layer may comprise chlorinated polyethylene. The tube layer defines a lumen in the hose, and a vapor return line may further be disposed within the lumen of the hose. Hose embodiments of the disclosure may be useful in fueling applications for vehicles using fuels such as gasoline, gasohol, diesel, biodiesel, avgas or jet fuel.
摘要:
The present invention is based upon the discovery that the level of adhesion between steel reinforcing elements and rubber products, such as conveyor belts, in which they are embedded can be significantly reduced by heating the steel reinforcing elements by induction heating to break down the level of bonding between the steel reinforcing elements and the rubber in the article. The present invention more specifically discloses a method for recovering steel reinforcements from a conveyor belt carcass having steel reinforcements which are bonded to the carcass of the conveyor belt, said method comprising (1) heating the steel reinforcements in the conveyor belt by induction heating to a temperature which is sufficient to substantially breakdown bonding between the steel reinforcements and the carcass of the conveyor belt and (2) applying a mechanical force to the steel reinforcements which is sufficient to separate the steel reinforcements from the conveyor belt carcass.
