METHOD OF COUPLING ALUMINIUM COIL BY BONDING AGENT |
摘要 |
The present invention is directed to a method and apparatus for joining aluminum members within an aluminum heat exchanger coil. A tubular member to be joined to a separate member in the coil has its exterior surface roughened by sand blasting to enhance adhesive adherence. The roughened surface is covered with a conversion coating to replace any accumulated aluminum oxide, to prevent the formation of additional aluminum oxides and to simultaneously provide a surface adapted to adhere to an adhesive. An adhesive is then applied to the mating areas of the tubular members to be joined and subsequently cured to form a tight secure joint. This invention is particularly useful in field repair of aluminum heat exchanger coils. |
