Conductive lubricant for magnetic disk drives

An improved disk drive system using a non-ferrofluid conductive lubricant is disclosed. In the disk drive system, there is a plurality of critically spaced magnetic disks rotated by a disk motor. A spindle shaft, which is retained by the spindle sleeve, couples to the disk motor and to the plurality of magnetic disks for rotation. The spindle shaft and spindle sleeve uses a bearing, which is lubricated by a non-ferrofluid conductive lubricant. The lubricant is used to prevent electrostatic charge build up during operation of the disk drive system. The lubricant may be either a non-polar oil or a ball bearing grease and further having either a metal caged fullerenes compound, STADIS-450, ASA-3, or Polyfloe 130. One particular type of lubricant is an emeraldine salt of polyanilin produced according to the steps of first reacting a solution of HCL and ammonium persulfate into a solution of HCL and analine to form a polymer. Next, the polymer is mixed with ammonium hydroxide and then is prepared to have a molecular weight of 1,000-20,000. Finally, the polymer is mixed with dodecyl benzylsulfonc acid or camphor sulfonic acid until the emeraldine salt is formed.

Corrosion reduction with amine scavengers

Corrosive amine salts in hydrocarbon streams such as desalted crude oil streams can be prevented or avoided by adding certain amine scavenging chemicals to the streams. Suitable amine scavengers include, but are not necessarily limited to, carboxylic anhydrides and copolymers of carboxylic anhydrides, aromatic anhydrides, isocyanates, polyisocyanates, and epoxides. The non-corrosive reaction products of the amines and/or ammonia with these scavengers are preferably oil-soluble, non-basic and thermally stable. The amine scavengers bind up and react with the amines and/or ammonia to keep them from reacting with materials such as acids (e.g. HCl) to form corrosive amine salts.
