Discussion on Application of Anticorrosion Technology for Bus Body
The anticorrosion mechanism has been analyzed in terms of eight aspects including the material type for passenger car panels,edge areas,welding after electrophoresis,coating process,film damage at final assembling,damping glue spraying,protective wax spraying and standardized parts for final assembling.By selecting the hot-dip galvanized steel and aluminum sheet materials,the film failure on edge area is improved,meanwhile,the corrosion during the welding process after the electrophoresis and coating process is effectively eliminated.The film damage cuased by drill hole and collision during the final assembling is improved.Furthermore,by means of advancing the damping glue spraying process for wheel cover to the coating process,adjusting the protective wax spraying to the anticorrosion process,using Dacromet coating and applying standardized parts,the quality of bus body can be improved effectively.
