<p>A process of treating the inner steel walls and fluid handling and moving devices in electrical precipitation installations that consists essentially of the steps of cleaning said steel walls and devices, penetrating a liquid suspension of micro micron particles of graphite into said cleanted steel walls and devices so as to build up a smooth adhering and lubricating coating on said steel walls and devices, said suspension including substantially between about 5% and 25% micro micron particles of graphite by weight, between about 34% to 75% by weight of a solution of water and sodium silicate, with the sodium silicate present at about 40% of the solution, between about 2% to 10% by weight concentrated hydrochloric acid, between about 33% and 75% by weight of a solution of water and carboxy vinyl polymer resin wherein the resin is present in amounts between about 1% to 10% of the solution and between about 15% to 20% by weight water to form a slick smooth surface. This invention is distinguishable from others by reason of the process using micro micron particles of graphite in a liquid carrier that enables the graphite penetration of the steel walls and fluid handling and moving devices to build up a smooth coating.</p> |
