FEATURES OF CLEANING DETAILS SURFACE BY DRY ICE
Journal Title: Проблеми тертя та зношування - Year 2018, Vol 80, Issue
Abstract
The article describes the theoretical study method of cleaning aviation technic and equipment parts by dry ice, which is more effective in comparison with other methods of purification. The comparative characteristics of other surface cleaning methods are given. The obtained analyt-ical data describe the advantages of the purification method dry ice granules using. But it is necessary to take into account the cost of equipment and raw material (dry ice) and a friction coefficients of shoot out dry ice granules supply through a pistol and special nozzles. Today we can see a tendency to accelerating and improving the operating conditions and technology of maintenance and repair of aircrafts in Ukraine. Any repair or maintenance includes the processes of external washing after receiving, cleaning and washing before applying protective and decorative coatings, a complex of work of aircraft parts, consisting the processes of prod-uct cleaning, application of defectoscopic materials (with capillary control). Based on the ob-tained results, we can draw the following conclusions: dry ice processing is an absolutely dry process, because the dry ice pellets consist of CO2 and evaporate immediately upon contact with the cleaned surface; the equipment does not produce waste, except for the pollutants itself, and make high-quality method of cleaning is absolutely non-toxic without using haz-ardous chemicals; dry ice treatment is not abrasive and does not damage the surface of cleaned parts; the combination of high cleaning speeds and a wide range of nozzles means that even normally unavailable elements can be quickly cleaned up; In some cases, dry ice treatment can be used without additional disassembly and installation of equipment, which reduces the time for process simplification.
