Show HILL TOP TIMES Friday, April 11, 1986 (from page dry paint residue. 1) Sacramento ALC at McClellan AFB, Calif., is testing a "flashlamp" paint stripping process which employs lamps mounted high-intensit- y in a water-coolehousing. The lamps are strobed at the work surface to vaporize the paint, leaving only a carbon residue. Warner Robins ALC, Robins AFB, Ga., hopes to test an experimental laser stripping process late next year. Used with moderately powered lasers, the process will be integrated with robotics for application and control. New technology is also being employed to replace chromium plating processes and the hazardous waste problems associated with them. For example: San Antonio ALC, Kelly AFB, Texas, has an operational plasma-spracoating process for parts which previously required chromium plating. An automated process, it applies d y , thermal barriers and wearresistant cowlings on critical engine components. The control system uses an automated, guided shuttle cart and two gantry robots to move parts into the cell and to apply the plasma coatings. The process not only replaces the use of chromium tanks, a major source of hazardous waste, but also improves conditions for employee safety and health. In addition to new technology, chemical substitution and filtration are also being used successfully to reduce waste, according to General Cornell. For example: Aerospace Guidance and Metrology Center, Newark AFS, Ohio, is looking into use of Cylsonic cleaners as a replacement for Freon. This process, which uses sonic vibration in a biodegradable detergent bath, is expected to reduce operational expenses, as well as hazardous wastes. Ogden ALC uses a filtering system to clean chemical paint strippers prolonging their life from months to years in some cases. Chemical analyses are used to tell when new stripping agents are required, rather than blindly emptying chemical tanks on a set cycle. General Cornell also cited reclamation and recovery of metals and chemicals as a technique being successfully employed to reduce waste. For example: Sacramento ALC has two metal recovery systems in operation. A distillation process separates cadmium from rinse water, allowing the water to be reused and returning the cadmium to the plating tank. A closed-looprocess uses ion exchange to treat chromium rinse water. Chromium is returned to the plating tank and the cleaned water is sent back to the rinse p and petroleum products last year. d At Warner Robins ALC, a was used recovery system last year to recover 30,000 gallons of purging fluid and 3,000 gallons of JP-for a savings of $107,000. Maintenance activities at AFLC bases are also expanding efforts to segregate waste products for either reclamation or for resale. San Antonio ALC reduced the number of drums of waste material destined for disposal from 3,000 to 2,000 barrels, a savings of 33 percent over the past year, through improved collection, identification and segregation of materials, General Cornell said. Treatment and disposal alternatives, including pretreatment and incineration, are also being studied by AFLC, according to the general. Sacramento ALC is evaluating a biological pretreatment system for the reduction of phenols, while Oklahoma City ALC has just completed a study of photo-ozon- e pretreatment of electroplating wastes which indicates that cyanides can virtually be eliminated from the waste stream. "As disposal regulations become more stringent, we will be forced to solar-powere- 4 consider incineration as an alternative to current disposal practices," General Cornell said. "This idea is being pur- in-hou- se sued by maintenance and civil engineers ... the only problem is we have yet to see one demonstrated that will meet Environmental Protection Agency requirements. However, this technology is developing rapidly and I anticipate we will be acquiring hazardous waste incinerators at all of our bases over the next 10 years." The command's senior civil engineer said, "Incineration is the next major step we must take to significantly reduce hazardous waste disposal." (AFLCNS) projects enhance quality working areas here Self-hel- p tank. Oklahoma City ALC uses an ion exchange process to recover nickel from the waste stream. According to General Cornell, Warner Robins ALC and AGMC are leaders in use of chemical recycling in their industrial processes. In fiscal 1985, they saved almost $1.7 million in new chemicals and avoided costs associated with disposing of 157,000 gallons of hazardous waste, he said. The centers are also segregating some wastes for recycling by contractors, the general said. The recycled material is either reused by the Air Force or sold by the Defense Logistics Agency, he explained. This arrangement is estimated to have saved AFLC from disposing of 5,600 barrels of waste solvents, calibrating fluids By Bob old windows along the east wall on the second floor were removed and replaced with a single window of thermopane glass. Spaces left by the old windows were bricked up. In addition, the entire hallway was repainted and vertical cloth blinds were hung to complete the project. In a recent quality of life competition, the division placed third in office areas and break areas. In the next competition, the Product Sup- Ketterer Directorate of Maintenance Directorate of Maintenance employees working in the Aircraft Division, Bldg. 225, are enhancing areas through then-workin- g self-hel- p projects under the Quality of Life Programs. Since last year, they have 78 projects, either in work or completed, ranging from minor repairs in office areas to larger contracts. Presently, the interior walls in the four hangars are being painted, with an estimated completion date in September. In another project, now complete, - port Unit Office will be submitted. Employees are now replacing its carpet and repainting and hanging vinyl wallpaper so it will be ready for judging. ' IT'S HERE! SPRING THE FOURTH ANIMATED CLASSIC FROM DISNEY! VALUES!
