Maintenance repainting

Oleo-resinous binder with zinc dust and graphite pigments Generally called zinc dust graphite paint, this relatively cheap material can resist temperatures in the range of 200-300°C. However, regular maintenance repainting will be required.

The wastes generated during paint application are primarily due to 1) paint overspray, and 2) the failure of the application which requires the stripping, cleaning, and repainting of the item. Source reduction can be achieved by use of low overspray application equipment, proper operator training, preventive maintenance, and parts inspection. 

If BkPdr is spilled on benches or floors, all work in the vicinity must be stopped until the pdr has been removed and the expl hazard of any remaining dust or fine particles has been removed by washing down the area with w Most of the above operations belong to maintenance activities. To these may be added repainting marking of containers, replacement of metallic caps, etc... 

Maintenance of bombs(maintaining them in serv-icable condition for immediate use) includes derusting, repainting and removal of exudate from the bombs and the floor of magazines. Removal of exudate from the floor is done by pouring hot water over it and scrubbing. When a comparatively small amt of exudate is present on the exterior of bombs, it can be removed with acetone and the bombs considered suitable for issue. Where ex-cessibe exudate is present on the exterior of bombs, the lots involved should be reported to the Ordnance Ammunition Command, Joliet, 111 and held for disposition... 

Finally, the humid, tropical Johnston Island climate corroded parts of the JACADS building and equipment. For example, exterior steel support beams, pipes, and pipe supports rusted and required frequent repainting, and some pipe supports had to be replaced. Also, corrosion caused significant deterioration of exterior valves, instrumentation, and electrical function boxes. Army officials stated that, because they had underestimated how corrosive the environment would be on Johnston Island, they had not initially used appropriate corrosion protection materials. To correct the corrosion problems, the Army now uses corrosion-resistant paints and fiberglass equipment covers. Also, the Army hired additional maintenance personnel to perform preventive maintenance work on the building areas and equipment most susceptible to corrosion. 

Economic losses are divided into (1) direct losses and (2) indirect losses. Direct losses include the costs of replacing corroded structures and machinery or their components, such as condenser tubes, mufflers, pipelines, and metal roofing, including necessary labor. Other examples are (a) repainting structures where prevention of rusting is the prime objective and (b) the capital costs plus maintenance of cathodic protection systems for underground pipelines. Sizable direct losses are illustrated by the necessity to replace several million domestic hot-water tanks each year because of failure by corrosion and the need for replacement of millions of corroded automobile mufflers. Direct losses include the extra cost of using corrosion-resistant metals and alloys instead of carbon...
